Evening Grosbeak

Hesperiphona vespertina

  • uncommon
  • 40 km/h
  • Vulnerable

Cracks sunflower seeds with a beak built for industrial work. Mass-mailing in canary yellow.

Population
~3.8 million (global, Partners in Flight estimate); eastern North American populations have declined heavily since the 1970s-80s for poorly understood reasons
Habitat
Coniferous and mixed forest (spruce-fir in the north, pine in western mountains) during breeding; deciduous groves, semi-open woodland, box-elder/maple stands, fruiting shrubs, and feeders in winter
Fun fact
Despite its name, the Evening Grosbeak is vocal and active throughout the day — early naturalists mistakenly believed it sang mainly at dusk.
Range
Breeds across boreal Canada and the western mountainous US into Mexico, having expanded east to New England and the Maritimes in the late 1800s-early 1900s; winters irruptively and unpredictably south into the US; rare vagrant to the British Isles
Diet
Seeds (especially box elder, ash, maple, and locust), tree buds, berries, small fruits, maple sap, and weed seeds; readily takes sunflower seeds at feeders; supplements diet with insects (including spruce budworm caterpillars) and mineral-rich grit/gravel in breeding season
Size
0.19 m
Wingspan
0.33 m
Lifespan
16 years
