Features of Lark bunting bird
Lark bunting birds are average-sized songbirds, with a small, solid, blue color bill. They have a huge white color patch on their wings and they have moderately a small tail, with white color tips at the end of their feathers. Breeding male birds contain an entire black body with a huge white patch on their upper part of their wing. Non-breeding female and male Lark Bunting birds look similar and they appear with grayish tan with white color stripes.

The song is made up of a combination of trills and whistles, which is a soft hoo. Their nest is an open cup on the floor in a grassy region.
Sexual choice in Lark Bunting birds is predominantly interesting, as the option of a female mate is radically diverse from year to year. In diverse years, female Lark bunting birds show preference derived from the black coloring, size of beak, size of wing patch, including other characteristics of a male bird. The result of this great variation of female option from year to year is the preservation of hereditary variation in numerous dissimilar male sexual decorations.
A study determines body color, percentage of black against brown color feathers on the remains of the body, size and color of the wing patch, size of the body and the beak, and remaining mass, so as to evaluate the manifold features potentially chosen by the female Lark bunting birds. The success of the social pairing is measured, including total yearly fitness, finding female option as the main factor. Flexibility in the female option is preferred for adapting to transformations in social and ecological environments.
