Inbreeding.

[Achilles]

We are all well aware of the problems associated with inbreeding. How does Mother Nature avoid the problem with wild birds?

[Afshimo]

migration? adult birds chuck younger out the nest and territory? loss of food/feeding area so they move?

[Barbary Boy]

inbreeding in the wild is commonplace. a peregrine gets shot from its nest , there is a high probability that the bird that replaces it was reared in that very eyrie. if this gos on and on the resulting problems sort themselves out through natural selection. in captivity some people call it line breeding, which is ok up to a point but an injection of new blood will be required every 2 or 3 generations or so to avoid serious problems. i allways try to get totally unrelated birds for pairs but wuold not be averse to brother and sister for one generation if there was no other option, or son/mother, daughter /father, its ok to critisise this but if you have very rare, impossable to obtain species then this is an acceptable way to go for me , as long as its monitered and controlled.

In the wild its purely survival of the fittest

Ye gods! I agree with BB!<vbg>

Inbreeding doesn't seem to be much of a problem with birds. If you read some of the old cock fighting books, very close breeding was actually recommended.

Wolf populations in North America (for example) had a definite mechanism in place to increase the incidence of inbreeding, so there were several distinct races of wolves, some of which have since disappeared due to the interference of man.

As others have posted, it is the selection which is the key. All the rabbits in Australia are descended from a very few imported individuals. There are many more examples.

By the way, let's get the terminology right.

If it works, it's line breeding.

If it doesn't, it is called inbreeding....
