New HawkCount feature now online!
Have you seen HawkCount lately?
Now, when you visit http://hawkcount.org you can immediately see all the hawkwatches and the total hawks seen there for each day of the past week. Daily totals are listed for each site reporting that day, and you can then click on any site’s name to open and view its full daily report and the hourly totals. The daily lists for the current day (and for the previous day) automatically update every couple of minutes, so you don't need to reload the page to see listings of new reports as they come in.
The new tabular listing only displays the last week’s totals, but all of a site’s information is always available at that site’s page in HawkCount. Just click on Find a Hawkwatch to locate individual sites or select Monthly or Daily data summaries and then choose the hawkwatch you wish to view from the dropdown list.
For the first time you can now quickly glance through all reporting sites for a given day and see the total number of hawks seen in one spot. Check it out!

Raptor Bytes - hawkwatching morsels from around the web
On Tuesday (October 8th) it was nice to see www.google.co.uk celebrating the birthday
and work of ornithologist and illustrator William John Swainson. Though he
lends his name to the common name of three North American bird species, with
the hawk being the most important obviously, sadly we weren’t treated to the same
celebration on this side of the pond. You can read more about Swainson, his
work and his somewhat checkered history by following the link (here).
Talking of Swainson’s, this has to be one of the most sought
out species for any eastern hawkwatch, and with the insanity of Broad-winged
season now passed, it’s a good time to be grilling those passing raptors for a
nice rarity. The majority of eastern Swainson's records seem to fall into a period from
early October to late November. One of my favorite blogs, Nemesis Bird,
produced a series of excellent articles on aging and determining the color morphs of
Swainson’s Hawks a couple of years back and you can see part one of the three part article (here).
Nemesis Bird is a fantastic blog with lots of lively and valuable content from a collection of excellent and interesting young writers. A bunch of the team for the blog are also self confessed raptor fiends so raptor fans will find much to enjoy there. Other posts have included such cool ideas as live blogging via ustream from their local hawkwatch (here). One of the Nemesis Bird team, Mike Lanzone, also sits on the HMANA Board. As well as the blog you can keep up to date with what the guys and girls from Nemesis Bird are up to on their facebook page (here).

Possum & Hawk Migration Studies - Luke Tiller |
I was excited to receive my fall copy of the HMANA Hawk Studies
Magazine and it looks like my dog Possum was pretty thrilled too (congrats if you noticed that he is looking at a Red-tailed Hawk, the awesome
Swainson’s shot is on the back cover). Fascinating articles on the
history of NEHW (so cleverly named they didn’t even need to adjust the acronym
when they changed the name) from good friend Neil Currie, in depth Raptorthon
reports from Laurie Goodrich, Hawkwatching in Hawaii with Lance Tanino, the fall
2012 flyway reports from across the country, an article about teaming up with
the Migratory Dragonfly Partnership and all complimented by some stunning and
often full color raptor photography from Steve Byland and Vic Berardi amongst
others.
Hawk Migration Studies comes as part of your HMANA membership package so if you aren’t a member already or haven’t signed up for the year you can do so by visiting the membership page of our brand spanking new website (here). You can also download membership brochures to distribute at your local hawkwatch and I would encourage members to do so.

Swainson's Hawk (dark juvenile) - Braddock Bay Raptor Research |
I'm wondering if everyone saw those cool little species maps that
eBird were producing - essentially an annual cycle of species reports . This one from March is for the Swainson’s Hawk (here). Interesting that it doesn’t register the increasing number of individuals that seem
to be overwintering on the Gulf Coast (perhaps still not in enough density to be picked up in this kind of data representation) .
These Gulf Coast birds have been suggested as the potential originators of some of the hawkwatch
sightings of Swainson’s Hawk across the northeast.

Migration in central Arizona
Adult male Cooper's Hawk, Sierra Prieta Overlook, Prescott AZ, 25 September 2013 |
Last year, my wife and I moved to Prescott, AZ. (near the geographical center of the state) and I immediately began looking at maps to find a good spot to see some migrant raptors. Mountains rise to the west and of town to just over 7000 feet. I noticed a pullout along a dirt road running along a southwest facing escarpment that dropped steeply to the west...the Sierra Prieta Overlook (SPO). Besides looking out over such a view, anyone visiting has to 'overlook' the broken glass from weekend revelry. This spot had potential.
Migrant raptors don't congregate in too many places in Arizona to make hours of watching pay off. Yaki Point, on the south rim of the Grand Canyon, has been operated by Hawkwatch International for several years and produces some decent flights. A good place to see Broad-wings reliably. Not far south of here is the Aubrey Cliffs IBA, a volcanic bluff running north of the town of Seligman. Arizona Game and Fish coordinates volunteers to cover this site during fall and decent numbers are seen. South of Tucson along the Santa Cruz River, a recently discovered passage of Gray, Common Black and Zone-tailed Hawks is the only other concentration of note. I wanted something a little closer to home.
So, with a bit of hope, my binoculars and a notepad, I ventured up to the SPO for a few days last September and saw...nothing. Local Red-tails and milling vultures. I knew the site wasn't going to produce a ton of birds, but maybe a trickle. But I would find out this fall that the site is fairly sensitive to wind direction and speed. I just needed to spend more time. My ego was bruised a bit, but not beaten.
Why not give Spring a try? I only spent parts of three days in late March and early April and noted migrating Turkey Vulture, Osprey, Northern Harrier, Sharp-shinned and Cooper's Hawk, Swainson's, Zone-tailed and Red-tailed Hawk, American Kestrel, Merlin and Peregrine Falcon. Numbers were low, but it was encouraging. Other commitments kept me from more days on the SPO, but my gut told me that more birds were passing the site. In a stroke of luck, I was able to convince the Arizona Field Ornithologists to award me a small grant to explore the site in greater detail in 2014. Fingers are crossed for good flights.
A couple of weeks ago, on 24 September, I found myself at the SPO scanning the hills and ridges to the north looking for migrants. I had to give the fall flight another chance. I wasn't disappointed this time. The winds were from the southwest (perfect) and there were birds. Needless to say, I was pleased. The totals for 5 hours of watching:
T. Vulture - 42
Sharp-shinned - 10
Cooper's - 24
Red-tail - 12 (difficult to get accurate with local birds confusing things)
A. kestrel - 12 (most of them before 9am)
Peregrine - 2
Total - 102
On subsequent days, I also observed a few N. harriers and Swainson's hawks, but overall numbers were significantly lower. For the first few days in October, the winds have been northeasterly, which isn't good for the overlook, and migrants have been scarce. But, I will be back up there soon, looking north. My goal for the season is a migrating goshawk. It's just gotta happen.
