[cayugabirds-l] more migration on radar tonight

[Dave Nutter]

Again winds are calm and birds are aloft tonight. Radar beams for weather go 
out in a straight line which rotates, forming a disc or shallow cone. Because 
of the Earth's curvature, the beam samples higher and higher altitudes farther 
from the radar station. After sunset migrating birds fly up to their cruising 
altitude intercepting that disc or cone thickly enought to show as up as a 
fuzzy or even solid area, but far enough away from the station the radar is 
sampling higher than the birds and it fades out. The result is an unmoving 
circular fuzzy cloud centered on the radar station, bigger and thicker on heavy 
migration nights like this. If you watch as it forms in the evening it seems to 
blossom, while in the morning it shrinks and retracts as the birds descent. 
Using doppler radar show the birds are moving, and this is a circular sample of 
a vast cloud layer.

[cayugabirds-l] Michigan Hollow

[Geo Kloppel]

I visited a plantation area on the west side of lower Michigan Hollow this 
morning, hoping for Pine Warblers. What I got was Red-breasted Nuthatches, 
Brown Creepers, Ruby-crowned Kinglets and Hermit Thrushes.

-Geo

Re: [cayugabirds-l] Swan Pen Yellow-rumped Warbler

[Chris R. Pelkie]

Kevin pointed out another Yellow-rumped Warbler yesterday up here on the North 
Wilson side of the Sapsucker Pond, but I only heard it then.
Today, I heard then caught up with it for some good looks.

This is FYI for Sapsucker Woods walkers this weekend.
It was near the beaver exclosure cage both days.

[cayugabirds-l] Avicaching update—early April

[Ian Davies]

Hi Cayugabirders,

With this bright morning and the forecast of warm weather for the weekend, it 
seems that spring may finally be ramping up. Many signs of the coming season 
are already here, especially in the wooded hills in our state forests. Forested 
slopes echo with the hesitant staccato beat of drumming Yellow-bellied 
Sapsuckers, and the jumbled notes of Louisiana Waterthrush song reverberate 
along rocky streams. Winter Wrens herald the warming weather with their 
impossibly bubbly song, and the thumping of Ruffed Grouse hums through the 
landscape. It’s a great time to be a birder.

If you’re interested in seeing these species, and many more, a great way to do 
so is through Avicaching! 
(ebird.org/content/ebird/avicaching/)

Avicaching is a good excuse to get out into the trails and forests around 
Ithaca, exploring new areas, seeing some fun species, all while contributing to 
the knowledge of our local birds. In addition, the more that you Avicache, the 
higher your chance to win a pair of Zeiss binoculars! Importantly, between now 
and the end of June your local birding can help us understand more about the 
effects that roads have on birds and bird surveys. Roadside bias is an 
important element of any research conducted on birds, and Avicaching is helping 
us understand these biases. All you need to do to help is go birding! 25 people 
have taken part already, contributing more than 650 checklists—you can see the 
stats and map of locations here: http://ebird.org/ebird/avicache/home.

This weekend should bring a host of new arrivals into town if the forecast 
holds true—a push of Ruby-crowned Kinglets, Palm, Pine, and Yellow-rumped 
Warblers, some additional Louisiana Waterthrushes, and many more tidings of 
spring! If you make it out to appreciate these returning species, consider 
checking out an Avicache or two—who knows what you’ll find!

Wherever you go, I hope that you find some good birds. See you in the field.

Best,
Ian
