What are the chances of survival for a bird? It is important for my school work..?

Depends on the bird. Usually it is inversly proportional to the size of the cache of eggs. Chickens for example lay a great number of eggs because they are flightless and pretty much defenseless. Mortality is high so the species compensates with prodicious egg laying. Interestingly this makes them an excellent livestock choice which has certainly contributed to the survival of the species.

at this point, I am very concerned since only insects outnumber the birds in the world and they are airborn. The mutation could occur at any moment and infect humans. This is how the flu of 1917 or so occured and spread rapidly

Here is a poem, but please use it only as inspiration:\nO' to hear the birds chirping, tweet, tweet!\nIt is such a lovely sound, O' so sweet.\n\nThis is what your teacher wants, but please write your own.

birds can be found all over the world. It all depends on what kind of bird.

Try this you may be able to sift through all the information and decide on where students may be able to help:\nhttp://en.wikipedia.org/wiki/Disaster_management\nThere are many related external-links at the bottom also.\n\nGiven all the natural and man-made tragedies in the world, it sounds like a great project

Eagles are listed as Threatened at this point.  They are not in danger of becoming extinct but of course that can change.  See the link for more info on Eagles

Extinction. \n  \n\nExtinction is a hot topic, of central interest to conservation, environmentalism and also to academic ecology. Ecologists are increasingly realizing that extinction has shaped the communities and ecosystems we see today, and that it operates on a range of timescales and spatial scales. \n\nExtinction doesn't just involve the complete loss of species, vanishing from the Earth. Extinction of local populations is often of key importance in shaping communities, even though other populations of the same species may exist in the same general area. \n  \n\nLocal extinction of populations. \n\nIn any area of forest, or patch of swamp, or coral reef, populations of animals and plants will be coming and going. If you were to compile lists of (say) all the bird species nesting in an fairly small isolated area of forest in Connecticut in one year then come back 20 years later, although most of the species in the list would be the same, the chances are that some of them would be absent (but quite likely replaced by other species). The ones that have come and gone would likely be the ones that had relatively few nesting pairs there anyway. \n\nWhy would they have gone extinct? Well, most often it would simply be that the population had a run of bad luck. Maybe there were 3 pairs nesting, and just by chance there for several years in a row there were late frosts that killed all the insects so the parents had nothing to feed their young, so the nestlings all died. Small populations are at the mercy of such 'bad luck', known as stochasticity. Even an initially abundant population (of say 150 nesting pairs) might still suffer a series of bad luck events (an exceptionally cold winter knocking back the population, followed by the late spring frosts) that can take it down from abundance to nothing at all in a few generations. \n\nAnother problem in a small population might be inbreeding. In species that normally have quite large populations and lots of exchange of genes, a range of harmful recessive genes can be present in the population without often showing themselves. Only when the population shrinks due to bad luck is there a significant chance of close relatives mating (e.g. if there are only 2 nesting pairs in the forest each year, the young are bound to end up mating with close relatives). When close relatives mate, they each have a good chance of carrying some recessive lethal genes in common; the result may be high mortality among the offspring. Experiments with repeated brother-sister crossings in domesticated animals (for several generations in a row) show that within 3 or 4 generations the young almost never survive to maturity because they have so many things wrong with them. This inbreeding effect is thought likely to hammer many isolated populations as their numbers get low, adding to the bad luck, although there are no well-documented cases of it occurring in wild populations. An apparent example of inbreeding effects appears to be the cheetah (see below), which has very low genetic variability apparently due to its numbers crashing to only 4 or 5 individuals at some unknown time in the last 10,000 years, then expanding rapidly again. Cheetahs have low fertility rates (e.g. very low viable sperm counts), and their cubs have high death rates that seem to be the result of its recent history of inbreeding. In this case, the population remained viable and recovered despite the inbreeding effects, but one can imagine that the problems might equally well kill off less lucky populations/species that reach very low numbers. \n\nObservations suggesting the importance of inbreeding in causing near-extinction:\n\n1) Gray Wolves of Isle Royale, Canada. The population was established by 1 breeding pair of wolves around 1949. By 1980 the population had grown to approximately 50 individuals, but by 1990 it had dropped to 14. Few pups were sighted by investigators who also noted that females were not breeding. Furth

Probably not. You might want to go and see if you can't find that little guy again. And then, try going to www.audubon.org and see if there is a branch near you that might be able to take the bird in, or find a local vet to bring it to. Because you really can't put the bird into a random nest - what ever kind of creature owns it will more then likely reject it as well, since it's not that particular bird's off spring.

I think we consider the idea of these researchers:\n\nGeochemist Christopher Romanek of UGA's Savannah River Ecology Laboratory (SREL) can determine the telltale composition of elements he finds in a feather through stable isotope analysis.\n\n"He can analyze a feather and tell us if that bird came from either a coastal colony or an inland colony by the carbon, because the salt marsh ecosystems utilize a different carbon than do the inland systems," said Larry Bryan, research coordinator of SREL's wood stork program.\n\nThe type of nitrogen Romanek finds indicates whether a wood stork is eating top-level wetland predators, such as large bullheads and catfish, or creatures farther down the food chain, including minnows, bluegill, crayfish and tadpoles.\n\n"That's interesting because the higher you get up the food chain, typically, the higher mercury concentrations you're going to have in these aquatic organisms," Bryan said.\n\nFor more than 15 years now, SREL researchers have studied the endangered wood stork (Research Reporter, Winter/Spring 1996). During the past three years, Bryan has recorded mercury concentrations in wood stork nestlings. The concentrations amount to less than a millionth of a gram, but they are high enough for the U.S. Fish and Wildlife Service to consider them potentially harmful. "Some of the nestlings could be at risk," Bryan said.

I don't think they are endangered, but, in National Geographic's book "Complete Birds of North America", it is listed as Uncommon to Rare.  It also says that there is no reliable information on population trends.\n\nSorry I couldn't be more helpful.

it can be every where specialy when  your country is hosting wild birds, but i wish this problem uprooted from all over the world soon.\n\nstay safe\nnn

Don't worry. you can buy a physiology book. then buy a dead animal,  then anatomise it. just do it ,  success belong to you.  good luck!

I would call your local health department and alert them. If you pick up the birds use gloves and place them in some type of receptacle so they can be transported. I think in this day and age it would be helpful for you and the public.

I don't think the male will incubate the eggs. I believe that only female eggs incubate eggs. I think you should take the birds to a shelter or store or something so they can live.

Depends on your Country but in my experience (UK) it is a central part of pest control strategy.\n\nWith your knowledge of bird control you should be able to identify buildings affected by bird pests.  Once identified you should be able to contact the building owners (not the maintenance contractor) and offer a short presentation on the risks and benefits of control.  I would also target car dealerships and local authorities.\n\nOffering a local paper an article on the problem might also be a good strategy ... there are always slow news days needing fillers.\n\nGood luck with it.

Something very similar happened to me two weeks ago.I found a dead bird on my front stoop.It didn't appear to be injured and it looked like it was asleep.But ,it wasn't.I'm not a superstitious person,so I don't know anything about that.I do know that a few years ago all of the crows in our area died as a resulty of west nile virus.I suspect the dead bird I found, might have been sick from something like that.

I agree with the above post in that if any research is being done, then it's still in the works, so it hasn't been announced yet. And genetically altering things, especially something as complicated as poultry, is a lot harder than most people seem to think. I would seriously doubt that anyone is working on genetically altering an entire species just to raise resistance to this strain of avian influenza. Any mutation in the flu and the genetic alterations would probably end up useless.
