Birds are the third most popular pet in the United States. Even though they are small and caged, birds still require a great deal of care and attention. They are complex creatures, and if you take good care of your own bird, you will have the opportunity to see what unique pets they are.
In general, the smaller domesticated bird species (canaries, finches, cockatiels, parakeets, lovebirds) are less likely to suffer from behavior problems than their wilder, more exotic counterparts. These species have been adapted to life as companion animals through long genetic selection. If you take proper care of them, most will never exhibit any behavior problems.
For those birds who do have behavior problems, the more common ones include frequent egg-laying by the female, or self-mutilating behaviors, such as feather-plucking. Such problems can be signs of boredom, dietary issues, incompatibility with cage mates, or stress.
Keep in mind that these issues are less frequent or non-existent in domesticated species, but can be seen more frequently in larger species.
