Winter Raptor Survey - Blizzard Raptors – Houtzdale WRS

Dark Rough-legged Hawk - Alex Lamoreaux
Guest Post by Alex Lamoreaux from Nemesis Bird
Earlier today I ran the Houtzdale Winter Raptor Survey in Clearfield County, PA. This 110 mile route meanders through pockets of grasslands, stripmines, agricultural fields, and forests from Tyrone to Curwensville and then up to Clearfield. When we left State College to drive down there this morning it was sunny and calm. About halfway, in Blair County, we spotted an immature dark type Rough-legged Hawk hunting in the median strip and perching in the trees along the road. I quickly pulled over to try for a few photos as it glided past us. I was shooting into the sun, but the bird was close enough to make up for it.

Once we got down to the beginning of the survey route clouds had moved in and it was beginning to feel like snow. Sure enough within an hour or two it was lightly snowing and the roads were already covered with over an inch. The snow fell harder throughout the day, and the wind picked up a bit. Needless to say, raptors numbers were a little low despite the great habitat along the route. Almost all of the birds we did see were perched in trees and trying to stay warm. We had 5 adult Red-taileds, all perched in trees along the route, 1 adult Red-shouldered Hawk that we inadvertently flushed out of a tree while driving. We had only 1 immature Red-tailed Hawk and it was perching right along the road, hunting and diving into the snow ahead of us. We also had 2 immature Cooper’s Hawks – one flying over the road and perching in a tree briefly, and another perched in a tree above the road. At a bridge over the West Branch of the Susquehanna River we got out to stretch our legs and had a nice fly-by Great Blue Heron and two female Common Mergansers.

Raptor Bytes - hawkwatching morsels from around the web

Battling Bald Eagles - Steve Beal
Not sure why but these raptor notes seem to be taking on a somewhat themed feel to them. Let's just roll with it shall we?

Eagle Festivals
Mid-winter can be tough on your average raptor enthusiast what with the beginning of spring migration still over a month away. Though there’s winter bird surveys to do (link here), looking for something to really entertain the less fanatical birders in your clan isn’t always as easy. That’s why when I lived in New England I always looked forward to the area's various Eagle Festivals. Even as a hard bitten hawkcounter that has racked up daily flights of almost 100 eagles at Braddock Bay (hawkcount link), it’s hard not to still get excited by any encounter with a Bald Eagle. As anyone who has stood at a hawkwatch with a group of kids, or adults, knows, just one eagle can inspire game changing awe, so when you get the opportunity to share a bunch of them with other people you have to grab it.

Personally I worked on the Connecticut Audubon Eagle Festival in Essex on the Connecticut River for a couple of years and it was quite simply amazing. Though they stopped running the festival a few years back, they still run the eagle viewing boats (details here), and if you've never viewed Bald Eagles from a boat you haven’t lived in my honest opinion! There are also excellent events run on the Hudson River near Croton (details here) and on the Merrimack River in Newburyport and Amesbury (details here). 

What are your favorite winter raptor events? Share them in the comments section or on the link from our facebook page.

Bald Eagle - Steve Beal
Eagle Myths?
I'm sure you've all heard the story that Benjamin Franklin proposed that the Wild Turkey should be the national symbol rather than the Bald Eagle. The truth of the matter is he really didn't. What he did do was complain in a private letter to his daughter, after the eagle had been chosen as the national symbol, that veterans' organizations might be better off using the turkey rather than the eagle (a symbol often used by European monarchies) for their organizations symbols (more here). Thanks to Rick Wright for steering me towards this, his blog has lots of fascinating posts about birds including things like 'Are Bald Eagles really Bald' (link here)!

Eagles in North American Birds
The most recent North American Birds, which is published by the American Birding Association (website here) and available to members for an additional subscription, has an excellent article (here) concerning a possible White-tailed Eagle that was reported from late April at Derby Hill in 1995. Though rejected by the state rare records committee, the sighting has been included in a number of publications on raptors. This most recent paper reevaluates the report referencing important developments in White-tailed Eagle identification. It's a fascinating article and one that is well worth a read. You can also read the original NYSARC (New York State Avian Records Committee) reasons for rejecting the report on their website (here). Worth noting that Derby is one of the sites closest to Braddock Bay, will be one of the conference field trips, and the date almost corresponds to our 2014 conference date (details here)! Not sure we can promise you a repeat of a rarity of that magnitude, but it does show the incredible potential of hawkwatches in the region.


Wild Russian Eagles
Talking of Eurasian eagles, I wonder if anyone else has been catching the rather excellent Wild Russia documentary series that is being aired by Animal Planet here in the US. The Kamchatka episode had some amazing footage I rather enjoyed of dueling eagles. Though this clip doesn't show the best of it, the Golden Eagle tangling with the heftier Stellar’s Sea Eagles was incredible.

Thanks to Steven Beale for the use of the Bald Eagle shots. You can see more of his excellent work on his photo blog (here).

Winter Raptor Surveyors can now enter data on line!

Surveying the landscape

Although HMANA has been encouraging its members to participate in Winter Raptor Surveys for a number of years, there has not been an easy way for surveyors to enter their data a la HawkCount.  The Winter Raptor Survey Committee has now succeeded in developing an on-line data entry procedure.

Log on to http://www.hmana.org/wrs.php and find out how to participate in what promises to be a valuable citizen science effort.  Winter Raptor Surveys provide an opportunity to a) bridge the gap between fall and spring migration; b) contribute to the growing understanding of seasonal raptor dynamics; and c) have fun.  

When you log on you will see the guidelines for selecting an area and designing a route.  You can then register your route, download a field data sheet, and look forward to having a lot of fun in the field this winter.  The data you collect will provide researchers with important information for, among other things,  studying the effects of global climate change on raptor distribution, for looking at fluctuations in gender and morph demographics; and population statistics which can be combined with migration studies and contribute to fine-tuning the Raptor Population Index.

Those who have done surveys in the past will be glad to know that they can register their routes and enter that past data for those routes.  If you have been doing surveys for a while, you should check the website above to read the changes in the instructions and to download the revised field data sheet.

This HMANA WRS data entry system is now ready for survey data entry. Because in the “back-ground” it is techni-cally still under development, the WRS Committee requests you report any problems or suggestions to wrs@hmana.org.  The Committee hopes that any “glitches” during this initial phase will be minor, and that participants will find the process of entering data to go smoothly.

Watching a hover-hunting Rough-legged Hawk illu-minated by bright sunlight reflected off a snow-covered field, seeing how amazingly silver a male Northern Harrier looks as it courses back and forth over that same field, determining that the
lump of weeds off to the left is really a Short-eared Owl --- all these experiences await you this winter.  Record them!  Ten years from now that information could be of great value.

California (raptor) dreamin'....

     In February the Bear Valley, like many other parts of California, is green with spring.  Farms, orchards, and vineyards carpet the valley floor.  Bordered on the west by the Gavilan Mountains and on the east by the southern Diablo Range, the valley is a visible manifestation of the San Andreas fault.  A quiet two-lane highway runs the western length of this striking landscape, a road enough off the beaten path that one can pull off to the side without fear of causing a traffic catastrophe.  And that's a boon to birders, especially hawk gawkers.

     It was one gorgeous late February day that we ventured southward from Hollister along the verdant fields and hillsides. The valley must be home to uncountable small furry critters and lizards and other tasty fare because we saw raptors almost everywhere.  A wide range of behaviors were exhibited: many were hunting, some of the birds were in dramatic courtship displays, some were engaged in what appeared to be territorial disputes, some were migrating, and some were possibly hangers-on from winter, not quite ready to head north.

     Red-tailed Hawks predominated, providing great opportunities to study a wide range of color variation.  I believe I have come to love the dark Western morph the most.  American Kestrels seemed to be everywhere, and I think I can truthfully state that I have never seen so many in one day anywhere other than a coastal migration watchsite.  They hover-hunted over fields, they were perched on utility lines, on fence posts, on small saplings.  They pestered Red-tails, they pulled the wings off large insects, they preened, they mated, and made us wonder if this was the Kestrel Shangri-la.

     Northern Harriers were probably the next most numerous, with silvery adult males as well as "brown" birds drifting back and forth above the grasses and marshy areas, and sometimes sitting on a fence. Red-shouldered Hawks were often perched on utility poles along the road.  We spotted the occasional Merlin zipping along parallel to the road, or perched on a snag on the steep slopes on our west side.  Here and there a delicate-looking White-tailed Kite captured our attention. Sharp-shinned and Cooper's Hawks were frequently spotted.  A side trip up into Pinnacles National Monument rewarded us with awesome albeit too-fast-to-get-the-camera views as a Prairie Falcon whipped over us at about 30 feet.

     When the frequency of Golden Eagle sightings equals what you might have of Red-tails in the East, you know you're in great raptor country.  Two Goldens acting a bit "courtship-ish" caught our attention as we scanned a horse pasture below us.  At another stop one appeared to be mantling over prey .  Sometimes, while watching a pair of Red-tails in the sky, a Golden would drift into view.  Then there'd be one that was perched on a rocky outcropping, or the archway of a ranch entrance.  At overlook pull-offs where we would be looking down on these birds, their golden nuchal feathering gleamed in the afternoon sunshine.

     Best of all to this Easterner, were the Ferruginous Hawks.  I spotted the first one when we were still about 400 meters north of it as it perched on a fence post.  It was definitely a "wow" moment for me, but the next three or four sightings of that species were just as "wow," as each of those long-winged buteos made certain we appreciated their majesty.

     Had we visited a week later would we have seen as many raptors?  Would we have seen as much diversity(12 species, including the abundant Turkey Vultures)?  What might it have been like a month earlier in that valley?  Perhaps some light could be shed on the situation by systematic monitoring such as the Winter Raptor Survey.  I'd volunteer, except that I live 3000 miles away!
