Now to the really good stuff!
The raptor migrations have begun here in Veracruz! If you’ve never experienced it is pretty mind boggling. Last year Pronatura Veracruz counted over 5.5 MILLION migrating raptors. The folks at Pronatura are one of the few groups doing anything about conservation and education here in Veracruz, I applaud their efforts.
(As a side note, three years ago when Tim Smart was here as a hawk watch counter he posted the daily results of the Veracruz count. I for one, really miss those daily reports on HAWKCOUNT/BIRDHAWK. The reports helped to give a true sense of the migratory marvel. I have mentioned it to both Norma Ferris and Rafael Rodriquez of Pronatura but so far the daily reports have not appeared. One of the mission goals of Pronatura is “environmental education” and the daily reports certainly contain migratory information.
If others out there miss the reports, I would encourage you to contact Pronatura Veracruz and see if they will share the information with the world.

I have set up house here in Paso de Ovejas Veracruz SEE MAP. From the rooftop of my small apartment I have set up a hawk watch observation post. I have been able to determine that most of the raptor migrations from the Chichicaxtle count site pass directly over Paso de Ovejas. I will make an attempt to share with you via this weblog observation highlights as well as photos.

MISSISSIPPI KITES ANYONE???
Yesterday, September 3, 2004 provides some of the best views of Mississippi kites of the season. Approximately 38,000 Mississippi Kites were counted by PRONATURA between Cardel 16,000 and Chichicaxtle 22,000
Here are some photos that I took from my rooftop viewing area here in Paso de Ovejas.
I observed a heavy “push” from 13:00 to14:00 with up to three lines moving through at the same time. Around 20,000 Mississippi kites passed overhead in the course of an hour!
Here are some photos. Enjoy!

Greetings from Veracruz:
For those of you who don’t know me, I’m David McCauley. I have lived in Veracruz for the last 12 years and began birding 6 years ago. I run a small birding tour business here in Veracruz, Birding Veracruz. I love Mexico. It is a wonderful country and its people are (for the most part) warm and friendly. It is of great concern to me the rapid loss of habitat here in Mexico. With over 115 species of migratory birds, (which either pass through or winter here in Mexico) concern over habitat destruction in Mexico and Latin America should be of interest to birders.
I note with some interest that a great number of birders in the U.S. have developed a “list fixation” and that issues such as habitat loss seems to be of very little concern. In many birding message boards conservation or environmental concerns are dismissed or banned.
Hmmmmm?
I don’t consider myself an environmental activist. Having grown up on a farm in central Washington and based on my observations here in Mexico, this farm boy thinks that it time to plant some trees south of the Texas border.
I am not much of a believer in causes and clubs or organizations. My goal in what remains of my life (I’m 51) is to purchase several small parcels (15 to 30 acres, each) of land in a variety of habitats here in Mexico and restore the original habitat. Its not much, but I believe that is a small step in the right direction.
The other project that I am working on here in Mexico are short presentations in the schools focusing attention on birds and their importance.
Small steps. I am optimistic that much can be accomplished here.

Raptor-Rapture!
Paso de Ovejas, Veracruz
The fall 2004 raptor migrations have begun. From the roof top and balcony of my rented apartment here is Paso de Ovejas, (MAP) I may have the best seat in the house for the observation of migrating raptors. On the 8-17 and 8-18 I observed over 140 Mississippi Kites and 10 Swallow-tailed kites in five hours of viewing.
In one “stream” I counted 40 Mississippi kites and 5 Swallow-tailed Kites.
From my
rooftop, I have a virtually uninterrupted 360 degree view. (Sunrise Paso de Ovejas)

It’s great to read the HAWKCOUNT reports from all the hard working teams in the US.
I love the names, Cranberry Marsh, Hawk Mountain Sanctuary, Allegheny Front, Wildcat Ridge, Waggoner's Gap, Bake Oven Knob, Second Mountain. I try to imagine what the hawkwatch sites must look like.

I also read with great interest the hawkwatch reports of Patty Waits Beasley from Corpus Christi, TX (Chocolate anyone?)
Corpus Christi movements provide me with a good ideas of possible raptor flows with two to three days anticipation.

In July I was able to photograph a juvenile Northern Potoo located a short distance from Paso de Ovejas. Here are some of the photos:

The Art of the Hawk Watch. Hawk Watch in Veracruz – River of Raptors
Birding is filled with a myriad of experiences that reward, that enrich us. Among these experiences, in my opinion, none are as satisfying as the often overlooked “Art of the Hawk Watch”
Each spring and fall a select group of birders drop everything to enter the realm of the hawk watch. First impressions can be deceiving, the hawk watch may appear boring, too difficult or too demanding from the exposure to the physical elements (heat/cold/winds) .
For many their first experience at a hawk watch is to spend many hours in the heat or cold and be rewarded by someone pointing out a distant speck and being informed that it was a Cooper’s hawk. After minutes of fruitless searching with the binocular you see something, it turns out to be the bread crumb from your ham sandwich that somehow got stuck on your binocular. When you do finally see something, it turns out to be a gull.
At the end of the hawk watch day (6 hours) you have see 17 birds of prey; 9 Broad-winged hawks , 2 Cooper’s Hawks, 3 Sharp-shinned hawks and 3 Turkey vultures, at least that is what the official counter says. The only good clear view that you got was a low flying Turkey vulture. You think to yourself, hawk watch? Whoopee! Great fun! Next weekend I think I will stay home and count nose hairs in the mirror. This is point where “been there, seen that, done that” can really take it’s toll.
If any of this sounds familiar, I have good news for you, not all hawk watches are the created equal.
I have the excellent fortune of living in the heart of what is probably the greatest migratory flyway for raptors on the face of the earth!
Last year over 5 million raptors, representing some 24 species were counted.

A little over a month ago, I rented a small apartment in Paso de Ovejas. Paso de Ovejas is located about forty minutes from the port city of Veracruz ( to the northwest), on the old highway that goes to Xalapa. I am here in preparation for the fall raptor migrations, River of Raptors .
For those who don’t know, I am a struggling nature photographer and birding guide and for most of the year I live in Tlacotlapan Veracruz ( a nice expanse of tropical wetlands located about two hours to the south of Veracruz)
I will be dividing my time between four weblogs, Birdwatch, Veracruz Hawk watch, Adventures in bird digiscoping and River of Raptors Veracruz. I will share photos, birding observations and try to give you some insight as to my daily life here in Mexico. I appreciate comments and feed back.

After five days of a combination of rain, strong winds and thunder storms, I have observed very little raptor movement.
Today we have sunshine so I will put in a full day observing and hopefully will see some nice 'pushes'.

Spring hawk watch
Tlacotalpan Veracruz Mexico

Rain, strong winds " Veracruz norte" on the 2nd and third. No raptor movement. May fourth, no migratory movement. I went out digiscoping and found plenty of Turkey Vultures roosting in the trees, many were soaring but not headed anywhere fast. I think raptors are waiting for more optimum migration conditions.

I got some good bird photos yesterday, some nice views of the
Bare-throated Tigerheron
Tigrisoma m.mexicanum

This evening I plan to make a post of the photos on my other weblog:

Spring Hawk Watch 2004
Tlacotalpan Veracruz


Some four hundred and fifteen years ago in the small Plaza that is now called Plaza Doña Marta, the documents were signed designating Tlacotalpan a pueblo.
Tlacotalpan means "land between sky and water"
The Mexican writer Elena Poniatowska once remarked "When I want to smile, I remember Tlacotalpan; when you pronounce the word Tla-co-tal-pan, it's as though you wash your face and laughter comes in."
There is alot of history here in in Tlacotalpan. Today another small bit of history was added. In the course of the afternoon, thousands of Mississippi kites streamed over the Plaza Doña Marta (6,333 Mississippi kites were counted today), it was during that time (when a group of tourists from Germany wandered through the plaza)) that we passed the 100,000 mark for the number of raptors counted in in 28 consecutive days here at the spring hawk watch.
As I reflect on the events of this month, I indeed feel fortunate to live in this special place and to have been witness to this spring raptor migration phenomenon.
I doubt that there are few spring hawk watch sites that offer this diversity, 17 species of migrating raptor species have been observed. In addition, 8 local resident raptor species were observed; Gray-headed kite, Black vulture, Snail kite, Common black hawk, Great black hawk, Crested caracara, Aplomado Falcon, Roadside hawk.
This adds up to a total of 25 raptor species in 28 days!

Tlacotalpan Veracruz

This was going to be my day off. I headed out to do some digiscoping/birding in the blazing sun, it was nice to get a bit of a break from the hawk watch. I was able to observe 73 species in about 3 hours.
Species of note: rufous-breasted spinetail, green-breasted mango hummingbird (male), barred antshrike, black-cowled oriole, bare-throated tigerheron.
While taking refuge in the shade of a tree, this Northern jacana, jacana spinosa caught my eye and I was able to capture some details. View 1 View2 View3 View4 View5

Once I got back to the house and had a bite of lunch, I walk out onto the porch and note that conditions seem right for raptor movement. So at 2p.m. I move the rocking chair and hawk watch gear out on the porch for a bit of viewing.
It is HOT 35C-95F. 10 km per hour wind from the south. Cloudless skies. At first glance, a few high flying resident black vultures. The sensation of waves of heat hitting my face, followed by the temptation to park the binoulars and take a nice long siesta.
To the southeast I notice a nice push of swallows, (barn swallows to be exact) in this part of the world during migration, swallows and lots of them moving steadily forward can be indicator of impending raptor movement. Within a matter of a minute, I see them, a rapidly moving, HIGH flying group of Mississippi kites (187 on the counter).
In an instant I am no longer tired, time flies and I enter the unique world of raptors in migration!
The rest of the afternoon is filled with some of the best views of the hawk watch thus far. 4.5 hours 3,299 raptors.
Mississippi kites (high kettle)
Broad-winged hawk
Swainson's hawk.
The highlight of the afternoon a fairly low flying female hook-billed kite!

Collage of flight profiles of the Broad-winged hawk. There is nothing static about a Broad-winged hawk in flight, the flight profile is constantly changing. I have created a collage showing different forms of flight of the Broad-winged hawk.
Please feel free to copy the collage, I hope that it will be helpful.

Plaza Doña Marta
Tlacotalpan Veracruz

The day started out crystal clear, fortunately we got a few clouds and some high haze that provided some eye relief for the spotting and counting of raptors.
We had four brown pelicans pass overhead, we don't see that many brown pelicans here as they tend to cling to the coast which is about nine miles away.
We had some kids drop by after school who wanted to observe, unfortunately I don't have but three binoculars for visitors and only one of them works. I guess I need to make a request to Birder's Exchange for some used binoculars.
It is a good thing if a kids interest can be sparked as to the ins and outs of the hawk watch.
The sight of the day was 2 Zone-tailed hawks. I was able to snap a quick picture of one of the Zone-tailed hawks in glide.

Spring Hawk Watch

Tlacotalpan Veracruz
I was going to go to Veracruz today, but when I notice that the winds were coming from the south I decided to postpone my trip and see what the day had to offer in terms of raptor migration. Southerly winds in the a.m. are not the norm. The morning and early afternoon were pretty slow but at 4:30 p.m. things changed in 15 minutes 3,000+ Mississippi kites came over the plaza.
It is a tremendous rush to see a line sreaming overhead, at times the Mississippi kites were 20 abreast. I was able to get a picture of a small kettle at the very end of the push.

Spring Hawk Watch

Plaza Doña Marta

Tlacotalpan Veracruz

BROAD-WINGED'S, SWAINSON'S, MISSISSIPPI KITES AND A FUNERAL
Here in Tlacotalpan the tradition remains of the walking funeral procession, between 10-11:00a.m. a funeral procession passed by the Plaza Doña Marta, site of the hawk watch.

Two days ago I made a post with photo "Sharp-shinned or Cooper's?" A sequence of photos that I had taken in the plaza of a low flying raptor.

Thanks to Van, (a keen observer from Colorado who responed to my post on Bird forum) who firmly stated it is neither a Sharp-shinned or Cooper's but rather something tropical, perhaps a Roadside hawk or a hooked-billed kite.
Well...........faux pas on my part and thanks for the correction Van.
After checking the few photos that I have of the Roadside hawk in flight, (the Roadside hawk-Buteo magnirostris is very common here) I am sure that what I observed was a Roadside hawk. A big serving of "humble pie" here today!
I have been birding rather intensively for the past six years in Mexico, almost everyday I learn something new. I supose that is why I enjoy this so much.
MORE CLEAR SKIES TODAY
Perhaps this photo will give you an idea of what I am dealing with while spotting and counting.
I wanted to post a couple of photos of the regulars at the hawk watch, Black Vultures. The "Tlacotalpan garbage dump gang" (black vultures) are generally the first to "get lift" in the morning and the last down in the late afternoon. They spend the day criscrossing the sky and are most definitely 'master's' at finding and soaring in thermals. In part I believe that one of the reasons that a fair amounts of raptors pass over Tlacotalpan is the very presence of Black Vulture, which are clear indicators of active thermals.

Thanks to those who e-mailed and responded yesterday, it is nice to hear from folks.<br> I just spotted our wintering peregrine falcon perched on the telecommunications tower here in Tlacotalpan, I am sure that it will be leaving shortly, I will miss it when it migrates but all of you up north will be enjoying will be enjoying your peregrine falcons. I noticed this winter on several occasions that our peregrine falcon is a bit of a gourmet. With good scoped views I was able to clearly view the peregine plucking a grebe, (either least or pied-billed) the lobed toes of the grebe being visible and unmistakable. I thought this to be a bit curious as I have always seen them munching on rock doves in the past.
This past fall while leading two birding guests, we witnessed a "kill" of a peregrine falcon and the victim was of all things a cattle egret. It was pretty impressive. I will try to make some notes next year as to peregrine snacks of choice.
As for yesterday's ID question, I went with the juvenile Cooper's hawk pretty much based on this PHOTO.
Note the progressively shorter outer tail feathers on the juvenile Coopers.

As for the hawk watch, clear blue skies and high flying raptors made counting a virtual nightmare. I could have used some help today! I estimate that I probably missed 50% or more.

Spring Hawk Watch 2004

HELLO! Is anyone reading this weblog or am I just mumbling to myself?
There is a space for comments on the far left side at the end of each post. I would appreciate hearing from you!
Blue skies are a raptor observers challenge(cloudless skies can kick your butt). Spend 9 hours scanning the blue for raptors and you will see what I mean!
Today was a fairly good day at the hawk watch number wise with 3,991migrating raptors tallied.
Late in the afternoon a cloud of rock doves flies over the plaza, their flight is not the normal flowing pattern of the rock pigeon. These guys are agitated.
I start looking for the source and spot a low flying accipiter, grab the digital camera (which I hand hold to the eyepiece of my binocular) and start taking some pics. This is not the easiest thing to do, but I am getting better at it. I was able to get about nine or ten pics of the juvenile accipiter. At first glance the pictures are not very sharp but they are useful for those who want to learn flight ID's for raptors.When you are observing raptors in flight most of the time all that you are dealing with is "shape" and these "shapes can change dramatically depending on what they are doing be it gliding, soaring or stooping.
In a time span of 40 seconds you can see the difference in the views of the same accipiter. This PHOTO COLLAGE represents the classic field challenge of IS IT A COOPER'S OR A SHARP-SHINNED HAWK?
Weigh in with your pick in the comment box, I will tell you later what I think it is.

Fifteen days into the count and I have counted 73,453 migrating raptors.
We had a vistor to the hawk watch site today. I noticed something sitting on the peak of a red tiled roof, to my surprise a migrating common night hawk. It stayed on the roof until things warmed up and flew away, it looked exhausted.

Spring hawk watch 2004
Plaza Doña Marta ("Martha" on the plaque in the plaza is a misspell)
April 15, 2004
Tlacotalpan, Veracruz
I spent a total of ten hours observing today. Most of the day the skies were crystal clear. Clear skies will put the skills of any any observer to the test, unless you spot the raptor with binoculars or a scope directly they may very well pass by undetected/uncounted.
Last year was my first time to conduct a hawk watch. As I compare last years count here in Tlacotalpan with this years the biggest difference is that I am scanning the skies more thus finding more. Most of the time I am counting by myself and that is a definite limitation.
I am not counting all the migrating raptors, however I am seeing enough to give an idea as to general movements.
Even at the the "Everest" of all hawk watches, River of Raptors Veracruz which is the fall count in Cardel and Chichicaxtle (where five to six million raptors are counted each season) not everything gets counted, and this is a team of dedicated and experienced counters.
I have to thank Tim Smart for teaching me a few things about spotting and ID. Tim is an excellent counter and his knowledge of raptors is quite complete. One of the things that I recall about Tim in Cardel is the near relentless form in which he is constantly searching the skies.
For those new to a hawk watch one of the most overheard comments is "I don't see anything", many times the problem here is that the binoculars are not pre-focused on a distant part of the sky. As a spotting tip, if you have a cloud with some detail, focus on it. Once focused you should be able to scan the sky and pick up many of the movements of raptors. When the skies are clear and your last focus was the low flying Monarch butterfly, when you get back to searching for raptors you can be certain that you won't see much more than another butterfly.

Spring hawk watch 2004
Tlacotalpan Veracruz
Weather not condusive to raptor migration. Overcast, rain and windy with a high temp of 23C-74F. I spent two hours in the a.m. at the plaza.
Raptor total 8 (1 Osprey and 7 Turkey vultures)
Due to the weather I took a break from the hawk watch to go out into the field and do some birding/digiscoping (Digiscoping is where you combine a digital camera with a spotting scope to take pictures)
My "digiscoping outfit is pretty simple I use a Sony Mavica 250CD camera handheld to the eyepiece of my Nikon 80 spotting scope.
Here are some of the results of the digiscoping system:
I spent 3 and a half hours in the field and was able to observe 70 species. The highlight of the day was a view (I was unable to get a picture) of a Western tanager (male). In my six years of birding here in Tlacotalpan this is my first sighting of Western tanager.
Here are five of the species that I was able to digiscope today:
Roadside hawk buteo magnirostris griseocaudaview one view two view three

Vermilion flycatcher (Male)
Scissor-tailed flycatcher Tyrannus forficatus
Mangrove swallow (this little swallow was perched on a fencepost and the background is color of the house behind it)
The HIGH POINT of my digiscoping day was this TENNESSEE WARBLER (male) Vermivora peregrina
view one view two
Well, you get and idea of my birding excursion for the day. I was nice to take a little break from the hawk watch but I am anxious to see what tomorrow will bring, hopefully the weather will improve.

Report on the Spring hawk watch 2004 Tlacotalpan Veracruz
Plaza Dona Marta
Tlacotalpan Veracruz
April 10, 2004

This is my second year conducting the spring hawk watch here in Tlacotalpan. One of the most frequent question that am asked is WHY WOULD YOU DO THIS?
When I am sitting on the porch of the house alone, 90+ degrees, 95% humidity , hardly a breeze ,zero raptor movement, scanning the scorching hazy blue sky, "Why do you do this?" seems like a perfectly valid question. On last years count with no tally board or explanation of what I was doing, I am sure that many of the locals thought "Well, it looks as though the gringo has lost his mind completely", they were kind though, they would smile and wave as they passed by. I have to admit that at first glance there is something rather "Kafka" about the whole hawk watch scenario.<
OK so back to the "WHY" of the hawk watch. My justification for observing raptors in migration or even birding for that matter is about making a connection.
Let me give you an example, the other day 12:00 p.m. (hotter than the hubs of hades) I am relentlessly bino scanning the nearly cloudless sky and a catch a faint glimpse on the horizon of a swirling "kettle". I spring from my tlacotalpan stlye rocking chair (rocking chairs are great for hawk watches) and grab the scope. I focus in and instantly see that good things are cooking in the distance, a good sized group of migrating broad-winged hawks is about to make an appearance over the small plaza called Dona Marta in Tlacotalpan Veracruz. I make a quick mental check of my data entry sheet, temp. wind direction, make sure that the clicker counter is ready, I step inside the livingroom, sling the digital camera over my neck and am back to the scope. I now can see that there are three independent "kettles" in the same area.
Now this is the moment that I call "raptor anticipation", the adrenaline has kicked in and I am ready. I quickly scan with the binos to the east and I pick up a small (150-200) "kettle". When you are conducting a hawkwatch by your lonesome and you detect multiple "kettles" this is what I refer to as a "situation". I call into the house to my partner of 10 years who is a gifted painter, "Rafa VEN!" Rafael comes quickly out of his studio with binoculars in hand, (you see , the "Rafa VEN!" command is reserved for special raptor movement sightings and is used sparingly.) I point in the direction of the small "kettle" and instruct him to tell me when they "stream" or break into a line as they leave the thermal so I can count them.
With Rafael focused on the movement in the east I return to my first large kettle which is breaking and a line forming headed directly for the Plaza Dona Marta. I make a quick mental note that the approaching line is approx. 15 abreast. I am able to count the first group with individual rapid clicks. The line ends and a see a break of empty sky. A quick glance at the counter 523. I scan back to the horizon and with one kettle counted I discover that a new kettle has formed, I now have three more to deal with.
Note: when "kettles" break or start to "stream" a counter had better be paying attention as raptors in glide don't dawdle. I have timed the movements of a breaking stream if raptors on the distant horizon, from that point until they pass over head 35-45 seconds. Of course there a few hard and fast rules as to raptor movements as winds, temp. can change quickly.
OK back to the task, I am now looking at a fair sized kettle, (in Tlacotalpan Veracruz that means1,500 to 2,000) I quickly jot the last line count 523 on my scratch sheet and reset the counter. As my next "kettle" breaks I note that they are approximately 20 abreast, grouped closely together, as they move out I am carefully watching the movement , each click of the counter represents 20. I am clicking at the rate of about one click per second, when this line ends, I quickly glance at the counter 76, I make a notation 76X20 on the scratch pad. At the end of the hour I will do the math and get a total for the hour. What the 76X20 means is that in 76 seconds I counted 1,520 Broad-winged hawks!
The next kettle has already broken and is almost over the house! Quick. Regroup and get the count!................... Perhaps this will give you an idea of a good "push " of raptors at a hawk watch and counting them. On this day at one moment I counted 7 active "kettles" at one time in the sky. The end result this day, 90 minutes, 11,000+ raptors. There were moments where these lines or streams kettled again directly over the plaza, filling the sky with thousands of swirling Broad-winged hawks! So this is why I observe raptors. I think that is one of nature's most awesome spectacles.

April 9, 2004 near perfect hawk watch conditions today high temp of 31C-84F and a consistent gentle breeze for most of the day.
Between 12:00-13:00 the sky filled with Broad-winged hawks, At one time I could observe 6 "kettles" at the same time. I counted the major streams but lost some of the smaller groups.
The hour count for Broad-winged hawks was 8,524.
the afternoon was nice with breeze and a good raptor mix riding the thermals over Plaza Dona Marta and no big hurry. In the afternoon raptors can fly in quite low making for some great views. We got a visit from a resident Roadside hawk looking a bit tattered
11 migrating raptors observed today plus 4 resident species for a total of 15 species observed.
Non-raptor species observed (21).
Around 11:00a.m. hundreds of thousands of migrating dragonflies passed by in a five minute period.

About as good as it gets. Tlacotalpan hawkwatch "sizzled" today(CLICK TO VIEW PHOTO. The day began with the filming of a new Mexican soap opera in Plaza Dona Marta. The rest of the day was good solid raptor movement. 8 species of raptors moved through today. Broad-winged hawks were by far the most abundant (13,875) Here is a pic of one "stream" of Broad-winged hawks, I counted over 1,500 in this one group. I WAS ABLE TO GET SOME PICS of what I believe to be a low flying juvie Cooper's hawk being pursued by some other birds.
Toward the end of the day's hawk watch, I noticed these girls playing with their pet racoon in the plaza. they came over to read the tally boad and I was able to get a pic

April 4 was a great day for a hawkwatch here in Tlacotalpan Veracruz.
I observed a total of 13 raptor species 10 of which were migrating. I made a rather rustic tally board to record the previous days totals as well as the totals for the season. I focused on the nine most observed species.
Today I observed some nice movements of mississippi kites and was able to digiscope several of their flight postures.
MISSISSIPPI KITES VIEW 1 2 3 4
There was some nice pushes of Broad-winged hawks in the a.m. To give you a sense of the numbers, I have taken this digital photo of the migrating broadwings and enlarged it to place a small yellow dot over each broad-wing hawk. The photo shows what Malcom Hodges aptly refers to as "sky pepper" There are over 500 broad-winged hawks in this photo. in this particular stream/kettle I counted over 2,000 broad-winged hawks in a matter of 20 minutes!
I got a bit of help with the hawkwatch yesterday from Jonathan and Jose, two local kids who have displayed an early interest in raptors migration. They helped for a couple of hours spotting and entering data.

All said and done and great day, 9,725 raptors counted for the day. Here is the breakdown:
Turkey Vulture 9

I have been working on my new website http://geocities.com/veracruzhawkwatch

I am dedicating some pages to different species of raptors in flight in order to help people ID raptors. I have photos of Broad-winged hawk, Swainson's hawks and Turkey vultures. I could use some flight photos of Sharp-shinned hawks, Cooper's hawks, Merlins, red-tailed hawks, red shouldered hawks, merlins, american kestrels, hook-billed kites, plumbeous kites, American swallow-tailed kites. They don't have to be close or super sharp as I am most interested in flight shapes. You can check out the page for and idea of what I am looking for. If you have any photos that you would like to share please contact me veracruzhawkwatch@yahoo.com

This weblog is about migrating birds of prey in Veracruz Mexico. It is called "River of raptors" because one may observe a steady "stream" of raptors on their southern migration. Veracruz is the "Everest" of hawk watch sites. Very few people have witnessed this natural event first hand. I am hooked on raptor observation and desire to share with others this incredible event.
