Corvus corax
Like a crow track, but noticeably bigger — and they often hop and slide in snow.
3.5–4.5 in long. Three forward toes, one strong rear toe. Larger than a crow print. Mix of walking and two-footed hops. Beak and wing marks around carrion.
Mountains, deserts, coastlines, boreal forest, towns. Northern Hemisphere, widely.
Diurnal
Carrion, eggs, rodents, scraps, insects
Ravens play — they've been filmed sliding down snowbanks for no reason at all.
Should I be concerned?
Harmless.
