Crested Cormorant Migration?
138410
Crested Cormorants typically nest in or around Denver in the summer months, around April - July, but they are not a very common bird there anyway.

Absolutely not.  They are warm-blooded creatures capable of maintaining an internal body temperature.  If birds were cold-blooded, you can bet that penguins and non-migratory birds would be in deep trouble when exposed to low temperatures!

Bald eagles were once plentiful in New Jersey. But by 1982, there was only one known nest and that nest had failed for 8 successive years. A group of scientists in the Endangered and NonGame Species Program (ENSP) of the New Jersey Fish, Game and Wildlife department decided to do something about it. Through dedication, the ENSP  re-introduced bald eagles into New Jersey.\n\nIn 2003 there were  40 nests with 41 young. Since 1982, the state has monitored the bald eagle population. The data that they have collected has provided important information about the health of the eagles and the health of the environment. Also, the data has been used to protect critical habitat for bald eagles.\n\n. Although bald eagle recovery has made significant progress in New Jersey, there is currently no plan to remove it from the New Jersey  endangered and threatened wildlife list. In spite of the successes, the bald eagle population in New Jersey is still under many pressures:\n\n    * Habitat destruction\n    * Water quality issues\n    * Persistent chemicals that exist in the environment and food sources that cause fertility problems\n\n 45 pairs of bald eagles in New Jersey are making themselves at home in Cumberland County, New Jersey. They're adding sticks to their nests and laying eggs or they're watching over eggs laid in February.\n\nThe local breeding population of eagles are not alone. Many wandering eagles from elsewhere winter in the wilds of Southern New Jersey and can be seen from March through early April.\n\nIn mid-January (2004) the Midwinter Bald Eagle Survey tallied 170 Bald Eagles in New Jersey. Most of them (126) were in southern New Jersey.

Yes, the Monarch Butterfly, during its migration in winter.  It travels almost non-stop to the south where its warmer, as much as 1,870 miles covered.

There have been plenty of studies but nobody seems to have a good answer!\n\nI visited a zoo last Sunday (my kids took me, lol) and there were plenty of sparrows there - nesting as well.\n\nhttp://www.birdsofbritain.co.uk/bird-guide/house-sparrow.htm

It lives in the Yenissei Area of the Taiga... Guess there are a lot of firtrees there! http://www.zooclub.ru/birds/vidy/228.shtml

Its not. There have been a couple cases in Africa I believe, but you also need to think about population density and where birds and people are migrating to and from most often. In this case where are birds and people frok Asian moving away from and to. Right now there are a lot of birds migrating in the Northern Hemisphere and so therefore more incidneces in the North. Please check out the CDC web site for more info.

It is actually a large sea bird.  For more info, please go here: http://www.aolsvc.worldbook.aol.com/wb/Article?id=ar010920&sc=-1

Strom-petrel is a type of small seabird in the family Hydrobatidae, part of the order Procellariiformes. These smallest of seabirds, relatives of the petrels, feed on planktonic crustaceans and small fish picked from the surface, typically while hovering. The flight is fluttering and sometimes bat-like.\n\nStorm-petrels have a cosmopolitan distribution, being found in all oceans. They are strictly pelagic, coming to land only when breeding. In the case of most species, little is known of their behaviour and distribution at sea, where they can be hard to find and harder to identify.\n\nStorm-petrels nest in colonies on islands, arriving in the evenings. One white egg is laid in a burrow in turf or soft soil. Both sexes incubate in shifts of up to six days. The egg hatches after 40 or 50 days; the young is brooded continuously for another 7 days or so before being left alone in the nest during the day and fed by regurgitation at night. Nestlings and parents leave the nest together after 60 or 70 days.\n\nThe name "petrel" is a diminutive form of "Peter", a reference to Saint Peter; it was given to these birds because they sometimes appear to walk across the water's surface. Early sailors named these birds "Mother Carey's Chickens" because they were thought to warn of oncoming storms; this name is based on a corrupted form of Mater Cara, a name for the Blessed Virgin Mary.\n\nThere are two subfamilies. The Oceanitinadae are mostly found in southern waters; there are 7 species in 5 genera. These have short wings, square tails, elongated skulls, and feed by hopping and fluttering on the water. All but one species have white underparts; the exception is Wilson's Storm-petrel which is also the only one to regularly migrate any great distance into the northern hemisphere.\n\nThe Hydrobatinae are thought to descend from an ancestor of Wilson's Storm-petrel. The 14 species in 3 closely related genera have longer wings, forked or wedge-shaped tails, and walk on the water rather than hop. All but two are wholly dark in colour. They are largely restricted to the northern hemisphere, although a few can visit or breed a short distance beyond the equator.

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.

Researchers have cracked the puzzle of how pigeons find their way home: they just follow the main roads.\n\nZoologists now believe the phrase "as the crow flies" no longer means the shortest most direct route between two points. They say it is likely that crows and other diurnal birds also choose AA-suggested routes, even though it makes their journeys longer.\n \nSome pigeons stick so rigidly to the roads that they even fly round roundabouts before choosing the exit to lead them back to their lofts.\n\nAnimal behaviouralists at Oxford University are stunned by their findings, which follow 10 years of research into homing pigeons. For the last 18 months they have used the latest global-positioning technology, allowing them to track the ground the birds covered to within one to four metres.\n\n"It really has knocked our research team sideways to find that after a decade-long international study, pigeons appear to ignore their inbuilt directional instincts and follow the road system," said Prof Tim Guilford, reader in animal behaviour at Oxford University's Department of Zoology.\n\n"For long-distance navigation and for birds doing a journey for the first time, they will use their inbuilt compasses and take sun and star bearings.\n\n"But once homing pigeons have flown a journey more than once, they home in on a habitual route home, much as we do when we are driving or walking home from work.\n\n"In short, it looks like it is mentally easier for a bird to fly down a road and then turn right. They are just making their journey as simple as possible".

I am not certain what you mean, but if you are asking about their breeding and nesting details, Here goes:\n\nWhoopers usually build a nest in marshes or shallow ponds, in about 25 cm of water (the flightless chicks can swim to escape predators) and most often in relatively dense stands of bulrush. \n\nA pair usually has two eggs. Both eggs generally hatch, but if both eggs are left in the nest, usually only one chick survives. The reason for this may be related to a food shortage, particularly when wet areas begin to dry out and terrestrial predators, such as the gray wolf, are able to penetrate the cranes' nesting marshes.\n\nThe incubation period is 29� 30 days, and both parents share the task of incubating the eggs in the nest. Few eggs are lost to predators thanks, in part, to the vigil of the adult birds. The reddish orange young hatch during the last week in May or the first week in June. From then on, the parents are kept busy feeding their chicks. During the summer, the cranes rarely fly. Some birds may be incapable of flight during short periods due to the molt of major wing feathers.\n\nFamily groups frequent the shallows of small ponds and marshes, where the adults perhaps find larval forms of insects such as dragonflies, damselflies, and mayflies, and also snails, small clams, water beetles, leeches, frogs, and small fish to feed their young. When the parent birds kill larger prey, such as snakes, mice, small birds, ducklings, and even birds up to the size of half-grown bitterns, they share the spoils of these hunts with their young.\n\nBy the end of September or early October the young birds are ready to try their wings on the 4000 km migration to the Texas winter range. On the way south, the birds spend one to five weeks feeding in their staging (stopover) areas in Saskatchewan. In these areas, undisturbed whoopers may spend the entire one- to five-week staging period on the same quarter or half-section of land. Here the birds fatten up on waste barley and wheat in stubble fields, and roost during the night in nearby wetlands.

I sure do wish I knew where you were and what grows where you saw the bird.  The link below is to my "Bible" of birdwatching sites with a link to the Eastern Bluebird - male and female.\n\nSecond link is to some other nature source information you might want to check out.

Hey, thanks for the question...\n\nI was about to answer that they don't, but in trying to back up my facts, I learned that apparently they do.  I guess you really do learn something every day!\n\nI don't see anything that clarifies their migration in particular, so I have to assume a lot of it is done by foot.  However, they can swim very long distances, and this may be a part of their travel methodology.
