The lark bunting (Calamospiza melanocorys) is a medium-sized American bunting native to central and western North America. It was designated the state bird of Colorado in 1931. The lark bunting is monotypic, the only member of the genus Calamospiza, and is not closely related to any other genera. It was first described by J. K. Townsend in 1837, from a specimen collected on a trip he took with Thomas Nuttall, under the name Fringilla bicolor. This is a preoccupied name, so Leonhard Hess Stejneger renamed the species in 1885 Calamospiza melanocorys. By then, the lark bunting had already been given its own genus, the one it is still placed in, by Charles Lucien Bonaparte in 1838.
Lark buntings are small songbirds, with a short, thick, bluish bill. There is a large patch of white on the wings and they have a relatively short tail with white tips at the end of the feathers. Breeding males have an all black body with a large white patch on the upper part of the wing. Nonbreeding males and females look similar and are grayish brown with white stripes.

Rare
Under 5% of wildlife watchers report a Lark Bunting sighting in Monterrey on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 177th most-seen of the 207 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Lark Bunting in Monterrey on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Lark Bunting sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Lark Bunting is recorded against all the birds logged in Monterrey (9 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
