About These Birds
American Crow
The American crow is one of North America's most familiar and intelligent birds. Research has shown they can recognize individual human faces and communicate perceived threats to other crows. They form large winter roosts of up to hundreds of thousands of individuals in some cities.
Wandering Albatross
The wandering albatross has the largest wingspan of any living bird, reaching up to 3.5 meters. These oceanic nomads can circumnavigate the globe, covering over 120,000 km per year using dynamic soaring with minimal wing flapping. Pairs mate for life and may live over 60 years.
