The Trill of Broad-tailed Hummingbirds –July 5, 2018

Turn up your volume and listen to the trill of male Broad-tailed Hummingbirds while you can. Male Broad-tails produce a loud trill with their wingtips as they fly, but over time the feathers that produce this sound wear down from use. By midwinter the trill is often inaudible. Before the next breeding season rolls around they grow new feathers and are once again ready to trill away
