Concerning the Blue Grosbeak
While the male Blue Grosbeak is vibrant and a bit chunky, the finch-like bird that lives in breezy habitats is usually recognized by a vocalization. When it is first seen, the male Blue Grosbeak is distinct, with the deep blue plumage highlighted by two Rust-colored wing bars.
Similar to the black-throated Blue Warbler, the genders of adult Blue Grosbeaks are able to be clearly discerned due to their distinct colors (a phenomenon called the sexual dimorphism). Females are mostly a subdued mix of brown and rusty tawny feathers occasionally with some blue feathers with blue feathers.
Both genders sport huge, conical bills as well as blackish tails and wings. Contrary to the similar hue, and smaller Indigo Bunting the grosbeak is known to flick and spread its comparatively long tail while it glides through the undergrowth, or rests on fences and wires.Although the bird is referred to as”grosbeak,” or “grosbeak” (literally”large bill) It isn’t associated with other birds of the same name.

Family Ties
The most recent mitochondrial DNA study puts it with the Blue Grosbeak in the Passerina Genus, which means that it’s the closest relative to Lazuli Indigo, Painted, and Varied Buntings, but not too similar birds like The Evening Grosbeak, which is actually a part of the finch family.
It is believed that the Passerina Genus falls into the larger family Cardinalidae which includes the rose-breasted Grosbeak, Northern Cardinal along with the Scarlet Tanager.
Subtle Songster
in his Field Guide David Allen Sibley aptly describes the Blue Grosbeak’s songs as “a thick, husky, and rich warble that has a distinctive, unbroken pace and a mumbled sound ….” While it is easy to listen to but this song’s rambling may go unnoticed, particularly when it is heard from a distance.
Males are the only ones who sing, however, a distinct sound is heard by both genders -A loud metallic “chink” which is usually the first sign that a Blue Grosbeak has been in the vicinity.
The Bluest Breeder
Male Blue Grosbeaks claim territories and seek out an mate with their song. The Blue Grosbeak is monogamous during the breeding season and males defend their loved ones by following her around when she is feeding. Similar to other blue-colored birds like Blue Grosbeaks, such as the Mountain Bluebird,
the vibrant coloring in Male Blue Grosbeak is a result of refracted light. the majority of it falls within the ultraviolet spectrum, which is invisible to the human eye. It is believed that males’ color reflects their breeder’s quality and this could affect the choice of a female grosbeak’s partner.
