Evening Grosbeak vs Pine Grosbeak (Hesperiphona vespertina vs Pinicola enucleator): The Complete Backyard Identification Guide
Quick Answer: The Fastest Way to Tell Them Apart
The two big winter grosbeaks. Three rules:
- Bill: massive and pale = Evening; small and black = Pine.
- Male color: yellow with a yellow eyebrow = Evening; rose-red with gray = Pine.
- Wings: one big white patch = Evening; two white wing bars = Pine.

| Feature | Evening Grosbeak | Pine Grosbeak |
|---|---|---|
| Scientific Name | Hesperiphona vespertina | Pinicola enucleator |
| Length | 6.3–7.1 in (16–18 cm) | 7.9–10 in (20–25.5 cm) |
| Wingspan | 11.8–14.2 in (30–36 cm) | 13 in (33 cm) |
| Weight | 1.9–2.6 oz (53–74 g) | 1.8–2.8 oz (52–78 g) |
| Overall Shape | A big, bull-headed finch with a massive pale bill — irrupts to feeders in winter | A plump, robin-sized finch of the far north — tame, slow-moving and deep-voiced |
| Male Plumage KEY | Yellow body, dark brown head with a bold yellow eyebrow band, black wings with a huge white patch, massive greenish-yellow bill | Rose-red head, breast and back over gray, black wings with two white wing bars, stubby black bill |
| Female Plumage | Silvery-gray with softer yellow touches, the same giant bill and white wing patch | Gray with olive-gold head and rump, the same white-barred black wings |
| Bill Shape KEY | Enormous, conical, pale greenish-yellow — a sunflower-seed crusher | Short, rounded, black — stubbier than an Evening Grosbeak’s |
| Tail | Short, black with white (male), forked look at rest | Long, notched, black |
| Core Range | Boreal and mountain forest of Canada and the northern US; irrupts south in some winters | Boreal spruce-fir forest across Canada and Alaska, western mountains; irrupts south in winter |
| Migration | Irruptive — absent some winters, everywhere in others, following cone crops | Irruptive — follows cone and berry crops south in some winters |
| Feeder Presence | Platform feeders heaped with black-oil sunflower — a flock descends like a gold rush | Black-oil sunflower at platform feeders during invasion years; crabapples and mountain ash |
| Favorite Foods | Sunflower at feeders; spruce budworm, maple seeds and ash keys in the wild | Buds, seeds and frozen fruit; sunflower at feeders |
| Song | No true song; calls carry the flock | A clear, fluty warble, rarely heard away from the breeding grounds |
| Flight Call KEY | A ringing, far-carrying “cleep” or “cleer” | A mellow three-note “tee-tee-tew”, often given in flight |
| Population Trend | Declining steeply — winter irruptions are rarer than decades ago | Declining in parts of its range; winter visits are the treat of an invasion year |

Song & Call Comparison
Evening Grosbeak
Calls: a ringing, piercing cleep — heard before the flock is seen.
Notes: finchy chatter and trills within the feeding flock.
Pine Grosbeak
Calls: a mellow, fluty tee-tee-tew, often in flight.
Song: a clear warble, mostly on the breeding grounds.
Range & Seasonal Presence
The Evening Grosbeak breeds in boreal and mountain forest of Canada and the northern US, irrupting to feeders far to the south in cone-crop failure years.
The Pine Grosbeak breeds in open boreal spruce-fir across Alaska, Canada and western peaks, drifting south in winter to fruiting trees and feeders.
Feeder Behavior & Favorite Foods
- Evening Grosbeak: platform feeders heaped with black-oil sunflower — a flock can empty one daily.
- Pine Grosbeak: sunflower too, plus frozen crabapples and mountain-ash berries.
- Irruption years: both appear far south of normal when northern seed crops fail.
- Behavior: both are remarkably tame — feed at arm’s length without flushing.
Temperament & Flock Behavior
Evening Grosbeaks are noisy, pushy flock birds that dominate every feeder they find.
Pine Grosbeaks are gentle and slow-moving, plucking berries at eye level and ignoring onlookers.
