Anna's Hummingbird (Calypte anna) Flying

Detailed Description

Anna's hummingbird (Calypte anna) photographed mid flight. Anna's hummingbirds are year-round residents of California where samples were collected for the development of a nonlethal method to test small birds for trace element concentrations. Seventeen naturally occurring trace elements, including those associated with adverse health impacts when birds are exposed to toxic levels (iron, lead, mercury, selenium, zinc, cadmium, and arsenic) were measured in small birds without harm with the new method. The method was developed for hummingbirds, with Anna's hummingbirds as a test species and can be more broadly applied to other hummingbird species. Source of photo.
