We are excited at waiting and watching for the hummingbirds to appear. Dorothy's letter reminds us of a message that's important to the well being of our backyard birds. During migration, birds are particularly vulnerable to predators. They are unfamiliar with their surroundings, and tired and hungry after the long journey. This makes them perfect prey for a cunning cat roaming outdoors.
Cats are dangerous predators for birds at other times of the year, too.
For example, most young birds leave the nest before they can fly well. Whenever you see newly fledged baby birds on the ground or taking short practice flights, remember that they are easy prey for a cat. Keep kitty indoors. Worldwide, cats may have been involved in the extinction of more bird species than any other cause, except habitat destruction. The American Bird Conservancy's first national poster competition was held last year and attracted entries from 28 states.
