From Rob :
New York City Audubon has a new tool for logging dead and injured birds and it's called "D-bird" (in Brooklyn we may call it "Da-Bird"). When you find a bird, often near a building with glass, you log the relevant info into D-bird, species, where found, age or sex if known, or anything relevant. If people make it a part of their regular birding activity D-bird can potentially map where high concentrations of bird mortality occur and thereby lead to remedies.
