Black-Capped Chickadees in Ultraviolet

Prolefeed Studios recently received a grant from the Wisconsin Society for Ornithology to study the plumage of Black-Capped Chickadees (Poecile atricapillus) under reflected sunlight in the near ultraviolet spectrum (300-400 nanometers). Many birds and insects can see a wider range of electromagnetic radiation than humans can, including the 300-400nm band. Several researchers have theorized that Chickadees, which appear uniformly black and grey to the human eye, might exhibit more distinctive markings under UV illumination.
