Anyone know anything about the flight pattern of a Black-capped Chickadee?

I'm not going to give you some useless chickadee facts.  If you are asking about the flight pattern, I assume you already know what one looks like and where it lives.  So I'll cut to the chase.  Regarding how the chickadee flies, it "rolls."  It flaps a few wingbeats and then brings its wings close to its body and allows itself to fall through the air like a torpedo, riding the momentum.  It then starts flapping its wings again.  Then falling, then flapping, then falling, then flapping.   This kind of flight acts to greatly conserve energy.  As far as migration patterns, they are fairly non-migratory in the States, sometimes ranging further south in the colder months and further north in warmer months.

I believe they're cavity nesters. In other words, they would nest in holes in trees in the wild, so it wouldn't look like much from the ground. They are also a common users of manmade bird houses.

Depends on the bird. Some settle down for the night alone, or on a nest. I assume you're talking about big flocks of birds like blackbirds and crows. Some of them look for a spot to roost together because of safety in numbers. They may fly all over at dusk to round up everybody and then fly to whereever they decide is a safe spot to spend the night.

Birds fly south because it is instinct. I hope that answers your question.

sounds like a warbler...but hard to tell from just this description, and not knowing where you live.  The two that pop into mind with that coloring could possibly be a Yellow-rumped Warbler, or Golden-winged Warbler. (maybe a female)\n\nhttp://www.mbr-pwrc.usgs.gov/id/framlst/i6420id.html\nhttp://www.enature.com/fieldguides/detail.asp?allSpecies=y&searchText=Yellow-rumped+Warbler&curGroupID=1&lgfromWhere=&curPageNum=1

There are several advantages to flying at night instead of during the day, some or all of these may have an influence on migration times.\n\nTaking their direction from the position and polarized light of the setting sun ensures that they start off facing the right way.\n\nDaytime predators such as falcons are avoided.\n\nDehydration that could result from flying for hours in warm, sunlit skies is reduced.\n\nThermals and updrafts are less common at night, without sunlight creating pockets of differential heating.  This makes night flying smoother, and more stable.\n\nFlying at night means that foraging activities take place on the ground during the day when most birds visual acuity is greater.  This means that food detection and selection as well as predator avoidance are scheduled at a time when their senses are best suited for the task.\n\nAt night the moon and stars are often visible, adding back-up navigational aids to the internal compasses and directional sense that the birds already have.

i did a small unit in animal behaviour and physiology and from what i remember .. birds have a much narrower vision (acuity of vision) which enables them to detect preys for examples from large distances while flying .. thats all i know, it not ... mm .. that informative.. but i hope it helped .. lol

ok\n Hoatzin chicks have archyopterix-style claws on their wings\n\nPuffin`s beaks are not as colourful out of the breeding season\n\nThe Goatsucker (no, not el Chuppacabra, the bird!) of the USA is called a Nightjar in the UK\n\nAmerican Robins are not related to european Robins, they are in fact a type of thrush\n\ncormorants have to open their wings to "dry" them as they`re not as waterproof as other waterbirds.

I'm guessing it was a tern. They may appear to have an orange ring because the base of the bill is orange and the end of the bill is black. They do dive.\n\nDid it look anything like this?\nhttp://www.mbr-pwrc.usgs.gov/id/framlst/i0700id.html

If it's a medium-sized, rather ugly mottled black/brown bird that congregates in the evenings to form a roost community then it may be grackles.  They have no song, just a rather raucous squawking call and when they gather by the hundreds in the trees nearby, they are a nuisance of the first order.  Much worse than pidgeons.  We have them in Texas and I believe that at different times of the year they plague most of the US.

Usually for nesting purposes.  Their homes are the northern region.  They will fly south to escape the winter months and return home.  When they get home in spring, they lay eggs and have offsprings.  They are used to the cooler summer instead of staying in the hot south during the summer months.

If it has wings it's a "fly"\nIf it doesn't it's  "grounded"!!! \nThat was a cute question. I'd never thought of that....LOL ;o)

Although the "balance" hypothesis sounds logical, experiments have determined that the head-bob of pigeons is rather related to vision.\n\nI'll quote myself (from the answer at the bottom link):\nHead bobbing has been hypothesized to be related to vision.\nWhen a bird's head is still, the images can form on the retina without the blur of motion. \nNow you're thinking: but the head is not still, it's bobbing! \nHowever, this is a visual effect, and in reality the head is keeping immobile, while the body moves. Head bobbing increases the stillness of the head during walking, running and landing. \nHead bobbing is not caused by an anatomical link of feet to neck or something like that; instead, it's synchronized with the movements of the feet, and although this could and has suggested a biomechanical function (balance, like our arm-swinging movements during walking), experiments have proven that head motions are determined by visual stimuli rather than biomechanical or inner-ear stimulation. \n\nThis is from a research paper:\nhttp://www.biomotionlab.ca/Text/TrojeFrost00.pdf

there may be some info here\n\nhttp://en.wikipedia.org/wiki/Humming_Birds

Although hummingbird migration is not well documented by large numbers of banding records, we do know a few facts, and we can draw logical inferences about some of the unknown areas.\n\nCLICK LINK BELOW FOR FULL DETAILS:
