The Indigo Bunting is particularly common at ROLF in the spring and early summer. Males are readily identified by their iridescent dark blue plumage. Females are a soft brown with blueish patches on the tail. Buntings along with Tanagers display complex molting patterns. In the fall male adult Indigo Buntings resemble females. Varying degrees of blueness may be observed. Indigo Buntings are sometimes seen feeding on lawns and make use of bird feeders.
