A little bit of birding

Yesterday I traveled around Cayuga Lake with Harvey, Tom, and Tim. It was only the third time so far this semester I've been able to really get out and bird heavily, so I was quite excited.

We started just before 8 at Stewart Park on the south end of the lake, to view the Slaty-backed Gull that has been a regular presence in Ithaca since January (See other Cornellian posts here and here). We picked out The Gull pretty quickly as it slept on the ice edge with all the others, occasionally preening or getting spooked around. We also picked out 2 immature Glaucous Gulls way out through the ice and heat shimmer, but the other Stewart regulars of Iceland and Lesser Black-backed Gulls were not present. Two vanfuls of Delaware birders showed up, and we scooted out as they got their taste of Ithaca gulling.


We began birding up the east side of the lake, hitting necessary stops such as Myers and Long Point. This area is largely agricultural, so we divided our time between driving around looking for flocks and scanning the lake for waterfowl. Two interesting finds in the hills included a small flock of Snow Geese in the fields, including at least one blue phase. They were close enough to the road to be able to hear their muttering, a very different goose honk than Canada, but not close enough for my camera to really capture their sound in video. Here's my best:





Another interesting inland find was a small mixed flock in the shrubberies near a house. Among such winter birds as Robin, White-throated Sparrow, and Goldfinch, we picked out three White-crowned Sparrows: two adults and one immature. One of the adults was even singing a few songs. The immature was interesting, and may have been a Gambel's race. I didn't get a detailed look at it and am not versed in the identification of White-crowned subspecies, so I can't really comment further there. One final inland bird before hitting the good scanning spots on the lake was an adult male Yellow-bellied Sapsucker - a pretty good woodpecker for the winter.

The lake was mostly empty, although it was beautifully clear and calm. It wasn't until we got fairly far up near Farley's Point that we got something besides geese. Hear was some of the lakes extensive Aythya rafts, tucked in close to shore where we could scope fairly easily. No super-unusual ducks: Redhead, Canvasback, Greater Scaup, Ring-necked Duck, Wigeon, Black Duck, Mallard, and Pintail were all present. There were also some scatterings of swan, including a bunch of Tundra Swan and 8 Mute Swans, a pretty high count for the Basin. The best bird on the lake was also present. An Eared Grebe has been on Cayuga Lake for several consecutive winters (just like Pacific Loon). It's been a little more difficult to find this year, being only occasionally reported from both the East and West shores, and there is some question as to multiple individuals being present. We were lucky, and the Eared Grebe was present at Farley's, swimming and diving just beyond the Aythya flock.

Farther up the lake, we passed the ice edge and waterfowl became restricted to the few open pools. More scanning revealed much the same as before, with added numbers of Tundra Swans and a few Trumpeter Swans as well, making for a perfect 3-swan day. On the ice-free ponds in Union Springs next to the lake, we did find some up-close Green-winged Teal, Gadwall, and Redhead. The pond's resident Eastern Screech-Owl was also basking in the sun from the hole of his duck box.


From here we headed up to the Montezuma wetlands complex. At some point earlier in the morning, we had started a raptor count due to the high numbers of hawks out in the beautiful February weather. Here at Montezuma we hit raptors in abundance. A quick check to see if the Wildlife Drive was open yielded a Rough-legged Hawk and Northern Harrier scuffling over the Main Pool. More Rough-legs and some Red-tailed Hawks were soaring in the distance.


A single field off of Route 89 held an incredible number of hawks in close proximity. In less than ten minutes at least three Red-tails, six Rough-legs, and three Harriers passed through this field. It must be loaded with voles! This same area yielded some half-hardy birds: Great Blue Heron and Northern Mockingbird.

From the Main Pool area we headed up north to the Mucklands area. These open expanses of agriculture, muck, and weeds have held reported Short-eared Owls recently. We of course had no luck in the middle of a sunny day (although one was reported that evening) but we did run into a flock of Redpolls. We searched the ~120 Common Redpolls but couldn't turn up a Hoary.


From the Mucklands we headed west, taking a short jaunt out of the Cayuga Lake Basin to bird the northern end of Seneca Lake in Geneva. Here we added Iceland Gull to our day's list, as well as an adult Lesser Black-backed Gull in Seneca Falls.


On the way back into the Basin, to bird down the west side of the lake, we ran into a Snow Bunting flock. Approximately 120 of them flew around from field to tree and back again. It was very odd to see a tree loaded with Snow Buntings, a typical open field bird.


One of our last birding stops was to stop at Sheldrake to scan the lake for the recently reported Pacific Loon. We couldn't find anything but Common Loons in the dying light, but we did see a male Long-tailed Duck and a male Red-breasted Merganser to make up for it.

The day concluded with a flat tire and ice cream at The Creamery (the ice cream is worth the inconvenience of having to put on the spare).

I think the highlight of our day was the sheer abundance of raptors. Here are our totals for our informal winter raptor survey:

66 Red-tailed Hawk (59 Cayuga Basin, 7 Seneca Basin)
15 Rough-legged Hawk (mostly at Montezuma)
8 Northern Harrier (mostly Montezuma)
2 Kestrel
5 Bald Eagle (all but one at nest: 1 at Mud Lock, 1 at Mucklands, 2 at Armitage)
1 Coopers Hawk
plus a Peregrine Falcon seen by Harvey on campus before the trip.

That's a pretty good day for the 'dead' of winter.

Bird family resources

If you are interested in family-level bird taxonomy, or even just want to view pictures and video of cool birds, here are two excellent resources:

Don Roberson's Bird Families of the World pages
Don does an amazing job summarizing the latest in family-level bird taxonomy. He has individual pages with information on almost all families, and includes a lots of information about changing taxonomic status (see the break-up of the Old World Warblers). Don is liberal with his family splitting, but this just serves to highlight diversity. This is the reference I use when I have any questions on bird families.

Handbook of the Birds of the World: Internet Bird Collection (IBC)
The Handbook of the Birds of the World is a series (still in progress) to illustrate and describe every species in the world. This amazing reference is, unfortunately, rather prohibitively expensive. If you want a taste, though, go to the Handbook site and view a healthy sampling of plates from each of the volumes. For example, check out Owl and Hummingbird plates here.
The really cool part of the Handbook online is the IBC. This is an extensive online collection of bird videos, some of which are really amazing. Here are some highlights:

Black Heron (Egretta ardesiaca: Ardeidae): displaying its unique feeding behavior. It folds its wings over its head to provide shade for poor, unsuspecting little fishies.

Hamerkop (Scopus umbretta: Scopidae): this unique African species, a monotypic family, destroys a Xenopus frog.

Sunbittern (Eurypyga helias: Eurypygidae): another monotypic family, this one from the Neotropics. Check out that display. And check out my close-up of a spread-wing of the species here.

Marvellous Spatuletail (Loddigesia mirabilis: Trochilidae): a male displaying its unique tail morphology. See my previous post on this species here.

Shoebill (Balaeniceps rex: Balaenicipitidae): monotypic families are cool. I'm pretty sure this one could kill you.

Kagu (Rhynochetos jubatus: Rhynochetidae): Run Away!


Note to students: If you use the resources to study, make careful note that the taxonomy of these sites doesn't always follow what we are teaching. Always refer to your Birds of the World handouts.

The Living Bird Online

The Cornell Lab of Ornithology publication, the Living Bird, is now online! Check out the new site, which features the latest issue, a lot of photography and articles from Macaulay Library's Alaska recording expeditions.

When you need to find the daddy...

It's amazing what heating and cooling and heating will do...

I and the Bird #68 - Winter Doldrum Edition


Welcome to the 68th Edition of I and the Bird! That is, if your flight over here wasn't delayed by "inclement weather" - the polite euphemism we use for blinding snow squalls. It is the deep of winter, folks, and that means radical changes in the way we interact with our feathered friends.


Gone are the days when 20+ species of warbler dripped from the trees. Sheets of snow and ice have blanketed the mudflats that once held hundreds of migrating shorebirds. You can spend hours slogging through snowy trails while barely hearing a single chip note.


This winter birding, or lack of it, can really get you down. Do you yearn for the spring to come? Do you grieve for the birds of summers past? The winter doldrums affect everyone differently. Let's see how they affect the birders on the blogosphere.


Denial

Birders are full of denial in the dead of winter, and will go to endless lengths to forget about the cold imposing winter around them.

Some, like Eva at The Flying Mullet go In Search of a Booby, and find one: "I paid the 50 cent fee and proceeded out on the pier. There were Rock Pigeons and Boat-tailed Grackles all around. At the end of the pier was my booby!". Unfortunately, chaos theory has yet to prove that tropical seabirds flapping in Florida can change the weather in New York.

Other birders, like Amila at Gallicissa, don't have to chase tropical vagrants, because they live in the tropics. In Birding with Malcolm and Duan, Amila gets out for a thorough birding trip in Sri Lanka. He's clearly just avoiding the New York winter.

Nowhere is denial more apparent than in Rick of Aimophila Adventures. His post, Mock Spring and an AZ BTB, describes his desperate attempt to turn an Arizona winter into a midwestern spring: complete with finding his first Arizona Black-throated Blue Warbler.

In another fit of denial, Charlie of 10,000 Birds abandons his homeland in the UK for supposedly sunnier grounds in California in Following in Corey's tyre tracks. Guess what he finds in California?
As utterly beautiful as the drive to Idyllwild was - and as startlingly bright and sunny once the clouds cleared - I have to say right now that from a birding point-of-view the next few hours were a touch disappointing. I spent most of the morning gripping the steering-wheel like my life depended on it (perhaps it did) which I’m sure didn’t help, and seeing vehicles coming back down the hill covered in so much snow that they looked like mobile snowdrifts did little for my confidence.
At least he did end up seeing good birds - check out the rest of his trip.

Then there are the birders who take their denial in another direction. They relax inside next to the warm fireplace, and ruminate on the latest ornithological findings.

Drew at The Nemesis Bird talks about varying female mate choice in Lark Buntings in The fickle females of the bird world.

Gavan from Gavan Central (Gavan) dreams of summer when he asks, Do birds get sunburn? The answer is far more complex than you might think.

When I am in full-blown winter doldrum denial, I have an outlet. I dive into the Cornell Museum of Vertebrates collections, and visit the wonders of the bird world via round skin with my Ornithology class. Along the way I hope I convey there are useful birding lessons in my Molt and Plumage Lab.

Anger

Nathan of The Drinking Bird in North Carolina doesn't deny that winter is in full swing. Tempers are short, however, and when he can't take anymore of the Scott's Oriole being seen by so many in NYC, he has to go out and see his own, along with other great western vagrants, in Great Scott!

Carrie of Great Auk - Or Greatest Auk?, writes a wonderful expose on Woodcock in Meetings with Remarkable Birds, but her prose can't completely mask the underlying tension:
Of course, that doesn’t mean you’ll see a Woodcock. What you’ll see, most likely, is absolutely nothing. Next most likely, you’ll see a feathery explosion of WHAT THE F*@! WAS THAT whistling rapidly away while you put your foot down in the spot where a Woodcock was.
With all this anger and unreleased tension going around, it's no surprise that bird bloggers are gravitating towards the lean, mean killing machines of the bird world: raptors.

Rob of Rob's Idaho Perspective discusses The Ways of Nature at his backyard feeders with the impact of a Sharp-shinned Hawk on other birds' behavior.

Trevor of Trevor's Birding captures great photos of an Australian raptor in Great Birding Moment #33: Collared Sparrowhawk.

Katie at bogbumper describes The Kill, in which a Sparrowhawk of a her own catches a meal.

Bargaining

Some birders deal with the winter doldrums with cooler heads.

Liza at The Egret's Nest believes it isn't too much to ask to get a beautiful picture of a corvid morning, even in the dull gray weather.

Katie at RSPB Notes on Nature, asks, Do you have a Swede in your garden?, because one day you might just find 16 imported Blackbirds in your backyard.

Behind the Bins knows winter drives a hard bargain, but is willing to pay the price with a Long Wait for the Hoary Redpoll, a life bird.

Depression

Sometimes there is nothing left after all the blustering and bargaining... sometimes you just have to except the fact that there are many more months of cold gray bird-deprived chill ahead of you...

Grrlscientist tries to stave off the depression by posting a video of The Tiny Secrets Inside of a Hummingbird's Nest, because: "it seems appropriate for today, considering that winter has closed her icy hand around us all."

The Ridger at The Greenbelt finds that when "it's cold enough to numb your fingers" you can still see Little gray birds on a cold gray day.

Sometimes it isn't the weather that gets you down, but the failures when you do get out birding. Mike at The Feather and the Flower describes an unsuccessful chase for a Ross's Gull that he shared with over a hundred of other birders around the northeast (myself included). Mike tried hard to remain upbeat in his post, Pretty in Pink, while I summed the trip up simply as:


Acceptance

Some birders quietly deny the icy grip of winter around them, others lash out by chasing birds or flying to faraway places. Eventually though, we all reach the point of acceptance, and get out and enjoy the winter birding to its fullest extent!

At Alis Volat Propriis, Leigh Kicks-off the year right, by getting out there and birding!

Tai at Earth, Wind & Water puts some additional observations into a previous sighting of an Ani in Carib specialty - redux.

Susannah from Wanderin' Weeta (With Waterfowl and Weeds) also gets out and about, in Birding in Three Stages. She even finds real glimmers of spring ahead!

The Wrenaissance Woman of Wrenaissance Reflections proves that even common feeder birds should never be ignored in her study of the finches at her feeder on a Finchy Friday

True acceptance of winter is mastered not when we just when we get out there and bird, but when we get out and bird for a purpose.

Birdfreak heavily promotes Citizen Science, while Island Rambles participates in the Yearly Bird Count for Victoria, BC and Patrick of The Hawk Owl's Nest joins in an Eagle Fest.

**Edit**
Sorry Duncan! Duncan's post at Ben Cruachan Blog slipped through the first pass. His post, A wander around the wetlands, goes to show that it ain't winter everywhere in the world.

Well, that about concludes this edition of I and the Bird! I hope you all have gotten over the winter blues and come to accept the fact that winter can be some really great birding! Now get out there and find some Snowy Owls or Gyrfalcons or Hoary Redpolls or refind that cursed Ross's Gull at Niagara!

All interpretations of people's moods are fictional (unless you guys really are angry and depressed?). Let me know if there are any problems/broken links/forgotten entries/questions/comments/hate mail at nds22 AT cornell DOT edu. Thanks!
