Media notes

Contributed for the female bird song project: femalebirdsong.org; female Cerulean Warbler singing from her nest (female song previously undocumented in this species); nest stage is incubation; ID'd and sexed visually, but also sexed based on incubation behavior, which is a female-only behavior in this species; this cut of songs given entirely by the female while she sat on her nest; we documented her singing like this from June 14-22, which largely overlapped with the incubation stage of her nest; will upload video showing the female singing while incubating at a later date
