Frequently Asked Questions

Do ravens and crows get along?

No, ravens and crows rarely socially interact outside aggressive territorial disputes. Their lifestyles and habits differ despite phylogenetic ties. Still, raven-crow hybrid pairs occur where their ranges overlap.

How can you tell a raven from a crow?

Ravens are noticeably bigger with larger beaks, shaggy neck feathers, wedge-shaped tails, and deeper “croaking” vocalizations. Crows have rounded tails, smooth feathers, higher-pitched “cawing” calls.

Do ravens eat crows?

Ravens may opportunistically predate eggs and nestlings of crows but they do not routinely hunt adult crows, despite the size difference. Territorial fights break out but cannibalism is uncommon among corvids.

Can crows and ravens talk?

No. But ravens and crows have impressive vocal repertoires used for communication. They mimic noises, use various calls in social interactions, and regional “dialects” suggest cultural transmission.

How do crows and ravens differ in behavior?

Crows often live in family groupings while mated raven pairs remain solitary. Crows scavenge cautiously but ravens boldly investigate novel items or environments. Different social dynamics suit each species’ niche.

Can crows remember human faces?

Yes, researchers find crows can remember specific human faces associated with threatening or caring experiences for years. Their ability to encode memories with emotional valence suggests episodic recall.

Why do ravens have jagged tail feathers?

Ravens evolved wedge-shaped tails to provide aerodynamic agility useful during aerial stunts and maneuvering. The specialized tail structure serves as a distinguishing ID feature.

Do crows mate for life?

Unlike ravens, crows do not form permanent pair bonds. Males provide food for their mates while breeding but most associations only last for a single season before the birds switch partners.

How has the intelligence of corvids evolved?

Evolutionary pressures for using tools, caching food, recognizing social dynamics, and adapting to diverse habitats selected for enhanced learning, memory, and innovativeness over time.

Do ravens have better vision than crows?

No evidence suggests either corvid species enjoys superior eyesight overall. But ravens’ adaptations to high altitudes may confer visual acuity advantages helping them spot carrion from vast distances.
