1. A bird's feathers are extremely important, and when they clean and smooth them, it is known as preening. Birds in the wild preen their feathers on a regular basis. This is true of
most captive birds as well, but not all. For example, some birds do not preen their feathers at
all. This problem is most common in birds that are taken from their mothers at a very young
age. Presumably, the absence of preening is due to the fact that they were never shown how
to do it properly. A more common problem among captive birds is excessive preening. Some
birds may pull out large numbers of their feathers or bite them down to the skin. It should be
noted that wild birds never exhibit this kind of behavior. There are several suggestions
about how the problem of excessive preening can be solved. Giving birds baths or placing
them in an area that has more activity to prevent boredom are suggestions. However, these
measures are often not sufficient to solve the problem.
