what makes wild bluebirds fight injured birds?

Question

we found a bluebird in the yard with a broken leg. other bluebirds were attacking it. My husband removed it to a cage with food and water

Answer 1

well nature is not always as sweet and pretty as we'd like. most types of animals--and many types of birds, not just bluebirds--will destroy a member of their species if they are injured or sick, it is a kind of survival of the fittest method. heck, humans used to leave their old people out in the snow to die when they became a burden. not that much different.

Answer 2

If you have found an injured wild bird, please contact a licensed wildlife rehabilitator. You can find one here: http://www.tc.umn.edu/~devo0028/contact.htm

These people have the training and the resources to deal with sick, injured and orphaned wild animals, and see to their eventual release back into the wild.

Please do not attempt to care for the bird yourself, especially if it has a broken leg. It needs medical attention, which the licensed rehabber is trained to give.

Also, in the US, it is illegal to keep most native wild species without the proper permits. In addition, if you do not have the proper training, you can do more harm than good. I like what this website has to say about it: "First of all, there are federal and state laws that prohibit keeping wild birds. And there are so many important but subtle elements to raising a wild bird that the job is only legally entrusted to licensed rehabilitators. Many well-meaning people raise baby birds or rescue birds from cats or after accidents, and sometimes they don't realize that the bird in their care is suffering from a serious dietary deficiency. Some of the problems aren't apparent to untrained people, but can cause death, or make the bird less likely to evade predators or to survive harsh natural weather conditions."

Answer 3

Since there are several species of blue birds, it is difficult to determine which one. Birds will kill and eat the youngest or the weakest if there is not enough food available. This is a way to insure survival for the remaining birds.

Answer 4

They're Blue Jays, not blue birds. They are very aggressive. They even steal food from dogs!
