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.
Eurasian Wren
The Eurasian wren is one of the smallest birds in Europe but possesses an astonishingly loud song for its size. Males build multiple dome-shaped nests, from which the female selects one to line and use. In British folklore, the wren is known as the king of birds for outwitting the eagle in a flying contest.
