Abstract

Using data obtained in 2002 and 2003 from sites in the Hummingbird Monitoring Network, we investigated the effect of geographic factors—latitude, longitude, and elevation—and year on hummingbird diversity patterns in Southwestern U.S.A. In California, none of these factors affected hummingbird richness but elevation significantly affected abundance. In southeastern Arizona, longitude and elevation significantly affected richness; year affected abundance. For all sites, elevation and longitude affected richness, year and elevation affected abundance. We compared these results with global hummingbird diversity patterns and suggest that the distribution of forest and rainfall patterns are likely important factors for conserving hummingbird diversity and abundance.
