Numerous birding journals have reported rapid spreading of disease in feeder birds in the last couple of years. House Finches seem especially susceptible through the East and in the Pacific Northwest. In Tucson, research on Cooper's Hawks has turned up new evidence that the impact of such diseases may not be limited to the primary feeder users.

Doves weakened by a protozoan that causes trichomoniasis are easy prey for the Hawks. The recent research shows that 85% of the Cooper's Hawk nestlings are infected. The disease affects the mouth and throat, and starvation is the result.

Because such diseases are spread by direct contact among birds that congregate to feed to bathe, it is suggested that birdbaths and feeding stations be thoroughly cleaned with diluted bleach, and that summer feeding be discontinued. Also, creating several small feeding areas instead of one large station is thought to be helpful.

Humming Bird Feeders
Like seed feeders, it is very important to keep their containers clean and their nectar fresh. Nectar must be changed or used at least twice each week, otherwise it may ferment, threatening the health of the Hummingbirds using your feeder.

Make sure to place your feeder with the bird's safety in mind. Hang it in a spot out of the sun and wind, about 6 to 7 feet from the ground, and away from any place accessible to cats.

Also, you needn't buy nectar to enjoy feeding Hummingbirds. You can make nectar by combining one part sugar with four parts water. Use hot water to help the sugar dissolve, but let your mixture cool before putting it in the feeder. Finally, don't bother to add any food coloring, nectar doesn't have to be red.
