Blue birds.....but are they bluebirds?

Mountain Blue Bird is the only thing that looks similar in my Audubon Bird Guide to the Western Region.  \n\nhttp://images.search.yahoo.com/search/images?fr=FP-pull-web-t&p=Mountain%20Bluebird

Maria, \n\nBirds are bipedal, warm-blooded, oviparous vertebrates characterized primarily by feathers, forelimbs modified as wings, and hollow bones. I will attach some links to follow for your question as it is a very detailed one.

Yeah, all ducks have webbed feet, although in some species the webbing isn't as complete and can be harder to see.\n\nBut the birds you saw are almost certainly coots. Your description fits them to a 'T' in both size, colouration and behaviour. Coots are vicious greedy little buggers.\n\nHave a look at the links below to see if they look familiar

I see it blue..isn't it??

Cool question. They are gregarious (like groups) wading birds related to other large wading birds such as \nBoatbills, Shoebills, Hammerkops, storks, ibises and spoonbills.\n\nYou can find the scientific classification and their spot in the bird family tree at the link below!

They vary. How strong and healthy are the birds?

This is sybil's first question. Try and give her a good answer.\nI'm sure someone out there has a good idea of what it could be.\nAnybody got a bird book? Cause now I really want to know too.

I think the word YET needs to enter your train of thought. 10 years ago there was no evidence to suggest that the Archaeopteryx wasn't the ancestor of all birds, now we know more and find that there is something that pre-dates it. In 20 years time there might well be eveidence to pre-date it yet further.\n\nWho knows what will turn up? Do you think this find discredits the theory of evolution or is it just the established theory of the evolution of birds that, until more evidence is discovered, has been undermined?

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

Not around here they aren't. I haven't heard any evidence to say they are, but it is possible. Not very likely however. I would say it is more likely that they are disapearing from a specific place, such as around you, because of changes in the climate, introducion of a new species that is competeing with or eating the bees, or something like that.

Blue Herons are (surprise) bluish gray, long legged long necked birds found in fresh water marshes and lakes, ponds.  They are found though most of the  US.  There are several kinds of egrets, but I assume you are thinking of the great egret which is similar in size and shape to Blue Heron but is all white.  They are found more around the coast from the Southern mid Atlanatic to Texas.  They tend to be more in salt water locations or in rivers near the coast.  There are several kinds of cranes, 2 inhabit the lower 48.  One is a whooping crane and incredibly rare , nearly extinct species that breeds in the Arkansas/Texas area.  Most likely any crane you would see is as sandhill crane tht inhabits various habitats in the interior of the country.  It is smaller than the heron or egret, is grayish in color and has a red crest on its head.

Maverick is right. If you look at a cladogram (a graphic representation of the evolution of birds) you will see  polytomies (several branches that arise from a single node) indicating that some of the basal relationships of modern birds are not completely resolved. And anyway, all modern birds belong to the Neornithes (a subgroup of Aves), so they all have a common ancestor that was more recent than Archaeopteryx or non-avian dinosaurs. \nCladogram showing position of birds within dinosaurs:\nhttp://www.mun.ca/biology/scarr/Natural_Classification_of_Aves2.gif\nhttp://www.geol.umd.edu/~tholtz/G104/birdorg2.jpg\n\nHere's another one showing the position of the major groups of modern birds (Palaeognatha, the large non-flying birds and the tinamous, and Neognatha, the rest of modern birds):\nhttp://www.usd.edu/biol/faculty/swanson/ornith/pics/phylogeny.gif\n\nThat said, there's a rare bird, the hoatzin (Opisthocomus hoazin), whose chicks have temporary claws on their hands (wings), which they use to climb and move about in trees. It does have an "ancient" look, although it is a modern bird, and some people have linked it with Archaeopteryx.

The answer is either “No” with a but or “Yes” with an and.\n\nRobins and chickens are totally separate species of birds. They are no more closely related than humans are to baboons. You wouldn’t expect a human and a baboon to be able to mate and produce babies would you? So no, robins and chickens can’t interbreed.\n\nHowever there are many different species of animal that CAN interbreed and produce offspring. But the different species need to be fairly closely related, far more closely than human and baboon… or a chicken and a robin.\n\nFor example we can interbreed horses and donkeys to produce baby mules, and we can breed cattle and buffalo, or camels and llamas. \n\nAnd the same is true of birds. While chickens can’t be bred with robins they are often bred with guinea fowl and pheasants for example, and occasionally bred with turkeys (see links below). \n\n\nSo to answer the question, yes different types of bird can mate and produce chicks, there's no doubt about that. But chickens and robins are not two types that are capable of it. Chickens and turkeys or chickens and pheasants are.\n\n\n>>>>>A robin and a chicken might be a stretch, but how about\n>>>>>two different types of sparrows? \n\nYes, in fact the various sparrow species are amongst the most likely to hybridise.\n\n>>>>>>Does it ever happen in the wild?\n\nRegularly. See the last two links.\n\n__________________________\n\nAddenda\n\nScientist said: "Only organisms of the same species can produce viable offspring"\n\nThat is simply not true. \n\nI know they teach you that in school, but it has no factual basis whatsoever and is not accepted by any biologist anywhere on the planet.\n\nJust to name a few examples cattle and bison, wolves and coyotes and fin and blue whales are all perfectly capable of breeding. They all interbreed commonly in the wild and the offspring are all perfectly fertile and have young themselves. \n\nEven lions and tigers will produce offspring that are capable of producing cubs, though most are not, and there have been at least 2 documented cases of mules having foals.\n\n\nUnless someone wants to argue that cattle and buffalo are the same species then ability to produce fertile offspring doesn't prevent two animals being seperate species in any way.\n\n\nSal said: "There are different kinds of chickens that can interbreed with each other. But a chicken can't breed with a turkey."\n\nA total lie with no basis in reality. I just provided links which prove that turkeys can breed with chickens.\n\nSal also said"This is one of thousands of examples as to why the theory of evolution is hard to swallow. If animals can change into other kinds of animals, you would be able to see at least a slight form of interbreeding betweeen different species, but you dont."\n\nWell since I have proved this belief completely wrong, and Sal now knosw that interspecies breding is common, even in the wild, I guess Sal will now accept evolution?\n\nYeah, right. Like facts and evidence played any part his belief.

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.

Because if they were green, people wouldn't call them blue birds.
