About These Birds
Common Raven
The common raven is among the most intelligent birds, demonstrating tool use, future planning, and social manipulation in scientific studies. In many cultures, ravens feature prominently in mythology as creators, tricksters, or messengers. Their complex vocalizations include over 30 distinct calls.
House Sparrow
The house sparrow is perhaps the most successful bird in the world at living alongside humans. Introduced to New York in 1851, it spread across North America within decades. Despite its global abundance, house sparrow populations have declined significantly in parts of western Europe.
