Bird metrics. Faye Romero, now a Ph.D. candidate at the University of Rochester and also a co-author on the study, says she spent many of her undergraduate years at the University of California, ...

They also studied museum specimens of Anna's Hummingbirds dating back to the 1800s — well before the popular outdoor bird feeders existed — providing a range of beaks to measure over about 10 ...

According to a recent study in Global Change Biology, a journal focused on environmental change, the use and prevalence of hummingbird feeders — like those red and clear plastic ones filled with ...
