The 1 millionth record was transcribed on February 8th, 2014 by Jane Gillette of Wakefield, MA. Vernon Bailey recorded the original observation of a house wren seen in New Mexico in 1904.
We have hundreds of species on our list for you to track, and we’d love to know what’s happening in your yard. It’s not too late to start observing! We’re especially interested in observations of deciduous trees, lilacs, and dogwoods.
