The Evening Grosbeak is a stocky finch with a heavy, thick bill. Males have yellow foreheads and bodies, with dark heads and shoulders, and prominent white wing patches. Females are olive-brown, with light underparts.
Evening Grosbeaks breed across parts of southern Canada into parts of the western United States. They are irruptive migrants - residents in their breeding grounds year-round, occasionally traveling in large flocks outside of their summer homes during the winter months in search of food.
The Evening Grosbeak was the American Birding Association (ABA)
Bird of the Year 2012.
Conservation
The Evening Grosbeak is listed as Least Concern on the IUCN Red List and was last assessed in 2012 by BirdLife International. 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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to 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.
