Some birds are endangered because of various things.
Like hunting, low population, having a hard time mating, poisons that are inside the animals/bugs they eat (which causes thin eggshell coating[the eggs will be destroyed when the mother sits on them] and possibly death), disease, lack of enviroment, pollution, hard time adapting, old age, non-native animal that's invading other ecosystems, something that was taken out or put in their enviroment/ecosystem (which causes the system to go wacko) ,etc.
Just go check out what's happening to other animals and see what comes up or research the history of Peregrine Falcons.

First off they are off the endangered list. They are still on the protected list. The main reason for the falcons and hawks demise was DDT. That was a pesticide that was used for farming. When the birds got their system full of DDT they would lay eggs with brittle shells. They had other reactions to the DDT but the very thin egg shells was the one that probably caused the birds to become endangered. I live in the burbs but had to quit flying my pigeons because the falcons and hawks would rip through the flock. There wasn't a day go by that the birds of prey didn't take two or three pigeons. The falcons will attack a flock and practice their killing techniques. They will dive and slice a bird up and fly back up and do it again over and over until the tire of it. I have lost as many as five or six birds in one fly.

because of pesticides we use in the past. The pesticides where injested by bugs and became some what poisonous and were eaten by larger animals (mice, fish, other birds). as it went up the food chain it became more toxic but to the immune system and reproduction system not the animal itself. So when the peregrine eats it's injesting the poison and when it lays it's eggs the shells are super soft because of the poison defect. The egg breaks when the mother sits on it, so not many are being born. If they are they are fed poison and many die young. Also they have prefered mates and don't just mate with any other falcon out ther.
