    Why do birds sitting on a power line all look in the same direction?

Birds fly and land into the wind for maximum lift and control of flight. All birds land into the wind, explains Bobby Harrison of Oakwood College in Huntsville, Alabama. These finches do likewise and, therefore, land facing the same direction -- into the wind.
The wind shifts direction, as it often does in springtime New Mexico, and the birds move with the wind, still heading into the wind and consequently still facing the same direction on the power line.

Now the wind dies. The becalmed birds begin to preen and hop about as the mood strikes and face different directions.

A few species, however, like the golden crown sparrow of California, still face the same direction. They do this even though no wind co-ordinates their choice, to keep relationships peaceful.

There you have it – when it is windy, birds face into the wind. Otherwise most species face randomly selected directions.

Many knowledgeable readers answered this question getting it right -- 77 per cent of the time.

Hey Bobbie, I remember a few years back watching something like this on Live cam. Is this the same? There were different cams for different Pubs playing some great Irish Music. Maybe it was St. Paddy's Day, who knows but it was fun.  bguitar

19794  Other Nature Related Information / General Nature Discussion / Improving your eBird reporting skills--Chickadees on: 14-Aug-10, 07:46:11 AM


At eBird data quality is of paramount importance, and we put a lot of time and effort into building the data quality process. From developing better automated data filters, to growing and managing the network of much appreciated volunteer experts who help review data, we strive for a clean dataset. In some cases this process is straightforward. Rare birds are rare, and these will always be flagged for review. But what about the common species? When two similar species occur together regularly in a region we can't easily automate the data verification process. For example, Black-capped and Carolina Chickadees both occur in New Jersey, but there is only a small area of overlap. Which Chickadee do you see? Are you reporting the correct species from your backyard? Over the years we've discovered a few groups of common birds that are often misidentified. This article is the first in a series to help shed light on these frequently misidentified species groups.

Chickadees

Chickadees are frequently encountered birds across much of North America, visible at backyard feeders and most wooded areas. They are common where they occur, and in many parts of the country only a single species is possible. Chickadees are largely resident, with only the extreme northern populations of Boreal, Black-capped, and Mountain chickadees moving marginally south in some years. In general chickadee movements are rare! They do form small flocks during winter, and often associate with other woodland birds.

The name "Black-capped Chickadee" could refer to any bird in this group, as all species have black or dark brown caps. Despite this, not all chickadees are correctly identified as "Black-capped Chickadees"! Black-capped Chickadee does not occur across the southern United States, and distinguishing it from other similar species where ranges overlap can be problematic. The biggest issues arise where it overlaps with Carolina Chickadee. The two are very similar in appearance, and birders need to use caution in the zones of overlap. There is no shame in reporting a bird as Black-capped/Carolina Chickadee if you're unsure. Excellent treatments of chickadee identification can be found in any field guide (e.g., The Sibley Guide to Birds), and we won't duplicate those efforts here. Instead we'll focus on distribution, and help you realize how each species occurs across the landscape.

The first step to accurately identifying chickadees is figuring out which species occurs in your area. In many places there is only one possibility. If you live in east Texas you're seeing Carolina Chickadee--done deal! In other places several species occur together, and in these places you need to be more careful.

Black-capped Chickadee is widespread across much of North America, absent from the Mid-Atlantic and Southeast, and from the Southwest. It barely reaches northern California on the Pacific Coast. It is a bird of high elevation deciduous forest in many places, occurring south into the Appalachians.

Carolina Chickadee:
Widespread and common throughout the Southeast stretching west through Central Texas, the Carolina Chickadee is the only chickadee species across most of its range. It occurs in a narrow band with Black-capped stretching from coastal central New Jersey, west through southern Kansas. In the narrow band of overlap hybrids occur, though these are often exceedingly difficult to identify. It is completely appropriate to report chickadees from the range of overlap simply as 'Black-capped/Carolina Chickadee', indicating that it is one or the other, but a positive identification was not reached.

The appropriately named Mountain Chickadee occurs throughout the montane West. It is rarely encountered outside of these regions, and is strictly a vagrant at lower elevations. In some places in occurs with Black-capped, Boreal, and Chestnut-backed Chickadees, but always look for this species distinctive white eyebrow!

Though widespread throughout the forests of northern North America, the Boreal Chickadee is less frequently encountered by birders than the Carolina Chickadee. Boreal Chickadee occurs only rarely south of the northern forests during 'irruption years', when a few make it to New England (mostly at feeders). It is not to be expected out of range, however, and any reports outside of the boreal forest will be subject to scrutiny.

Chestnut-backed Chickadee is primarily a bird of the Pacific Coast, stretching inland across Washington into parts of British Columbia and inland to Idaho. Across much of its southern range it is the only chickadee species, but it occurs regularly with Black-capped in the Northwest. Luckily it is relatively easy to identify, having a dark chestnut back and warm brownish flanks.

The Mexican Chickadee is the most range-restricted of all the North American chickadees, just stretching across the border into the mountains of extreme southeast Arizona and southwest New Mexico. If you aren't birding in the Chiricahuas in southeastern Arizona, you almost certainly aren't seeing a Mexican Chickadee!

The next time you see a chickadee in your yard, first remember where you are, and make sure the species you're reporting matches up with the possibilities in your area. Then take the next step and make sure to identify the bird based on its field marks and voice.

The Chappaquiddick superintendent for The Trustees of Reservations has resigned and Trustees are taking full responsibility for an incident late last month where an unfledged nest of least tern chicks was nearly run over by a Trustees-owned four-wheel-drive truck that was on the barrier beach conducting a natural history tour.  (Continued)

Those chicks are so cute.

19796  Other Nature Related Information / General Nature Discussion / Cincinnati Zoo Hawk Flies Away on: 14-Aug-10, 07:36:01 AM
Another Harris Hawk has flown the coop at the Cincinnati Zoo. "Tex" took off during a private demonstration Monday afternoon.
 
Zoo officials believe he's hanging out in the Clifton area. The size of a Harris Hawk is between a pigeon and a red tailed hawk. Zoo officials say its fairly common for demonstration birds to fly off - and the zoo has been lucky it hasn't happened more often.

You'll recall in June, another Harris Hawk named Tucson, flew away during the Wings of Wonder show.  It returned later the same day.

7:15   After A & B left the nest box, 1 went over to the NW side platform of Mercury. Archer now on 3rd Ibeam OCSR. Watcher's MAK, Dan, Dana. Lots of flying this morning.

I'm with you on this, Janet! Donna! WHAT are you thinking with Boone's Farm??? Great big "ICK"! Since you "never leave home" (haha!), get yourself a good book about The Wines of the World to entertain you in your idle moments... I would rather eat a swampful of frogs... with Brussels sprouts!... than drink that! Eeeeeeee-uuuuuu!

Waiter! Send the sommelier to her table, please..

Well C'mon, I was only 17 and that was the drink of choice back then and of course Boone's Farm Strawberry Hill....(yummy). I don't drink wine now....I'll take the old fashioned "Beer" and check this out Bobbie, I like "Guinness" and a nice German beer.
