Little Bunting (Emberiza pusilla) [XC456197]
by David Armini from Baikal Ringing Station, Tankhoy, Irkutsk, Russian Federation (call)
Little Bunting (Emberiza pusilla) [XC437067]
by Fraser Simpson from Mankhan, Khovd, Mongolia (call)
Nest
Usually in a tussock of grass, on the ground.
Eggs (Guide)
4 - 6; pale green with dark speckles and streaks.
Subspecies
No subspecies.
Sometimes placed in a separate genus, Ocyris. Recent phylogenetic study suggests that this species is closely related to Rustic Bunting (Emberiza rustica), Yellow-breasted Bunting (Emberiza aureola), Chestnut Bunting (Emberiza rutila), Yellow Bunting (Emberiza sulphurata) and Black-faced Bunting (Emberiza spodocephala), forming a subclade with them. It has been suggested that they form a polytomous group of species, probably the result of a rapid, "simultaneous" radiation.
