- Populasi
- ~3.8 million globally; eastern North American populations have declined heavily since the 1970s-80s for poorly understood reasons
- Habitat

- Fakta menarik
- Despite its name, the Evening Grosbeak is vocal and active throughout the day — early naturalists mistakenly believed it sang mainly at dusk.

- Makanan
- 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
