Scientists have found that when giant pandas mate with their preferred partners, they mate more often and have more babies, but if they choose to mate with their relatives, that would lead to less genetic diversity. However Fitzpatrick suggests this new insight into animal breeding behaviour should be something taken into account when considering human impact on the environment.

This includes proximity to other breeds, viability for mating, and/or the age of the bird. If they are unable to do so, it is going to end up showing through inbreeding and/or aggression. hybrid infertility . Genetic defects are more likely to be carried by birds with the same genes. As the mate-choice studies he looked at were all done with captive animals, it'shard to say how much this will apply to animals in the wild. Bears are extraordinarily intelligent animals. In situations such as this, you will want to make sure the two birds are separated. Standing up on its hind legs allows a bear to get more information from its senses of smell, sight and hearing.
