Black-billed Magpie vs Common Raven (Pica hudsonia vs Corvus corax): The Complete Backyard Identification Guide
Quick Answer: The Fastest Way to Tell Them Apart
Two big western corvids that share the wide-open West. Three rules:
- Color: black-and-white = magpie; entirely black = raven.
- Size: slim and jay-bodied = magpie; huge, hawk-sized = raven.
- Voice: nasal chattering = magpie; deep, resonant croaks = raven.

Song & Call Comparison
Black-billed Magpie
Voice: a harsh mag-mag-mag and a nasal, whining maa.
Behavior: noisy at carcasses and roosts; quiet when raiding nests.
Common Raven
Voice: deep resonant kraaak, croaks, knocks, and even mimicry.
Flight display: pairs roll and tumble while croaking.
Range & Seasonal Presence
The Black-billed Magpie lives in open rangeland, river bottoms and western towns, building domed stick nests in shrubs and trees.
The Common Raven owns wild country — mountains, desert, forest and coast — plus wilderness-edge towns. Both patrol western roads for carrion, side by side.
Feeder Behavior & Favorite Foods
- Black-billed Magpie: suet, meat scraps, peanuts and pet food on platforms.
- Common Raven: roadkill, garbage and large scraps — a rural feeder only in wild areas.
- Caution: both learn feeders fast; secure trash and pet food if you do not want permanent residents.
- Water: both drink and bathe at ground-level water.
Temperament & Flock Behavior
Black-billed Magpies are bold gossips — chattering in loose flocks, strutting with tail raised, teasing dogs.
Common Ravens are brilliant and playful — aerial barrel rolls, snow slides, and problem-solving that matches any primate.
