Justification of Red List category
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km² combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population justification
The global population is inferred to number 2,000,000 mature individuals (Partners in Flight 2019).

Trend justification
The species has been undergoing a large, significant increase (Partners in Flight 2019). Short-term trends suggest that the population in North America has been roughly stable over the past three generations (11 years) (Pardieck et al. 2018).

Crotophaga sulcirostris occurs in the Americas, from the U.S.A. south through Mexico, Guatemala, Belize, El Salvador, Honduras, Nicaragua, Costa Rica and Panama to South America, where it occurs in Colombia, Ecuador, Peru, Bolivia, Chile, Venezuela and the Netherlands Antilles (del Hoyo et al. 1997). The race pallidula, described from Cabo San Lucas in the early 20th century (Bangs and Pernard 1921), is probably now extinct.
