Ruff courtship and mating, a special and rare phenomenon to see. For the first time in 20 years it is again happening in nature reserve Waalenburg on Texel island . Around 55 ruffs were seen by Natuurmonumenten last week in Waalenburg. Courtshiping with their beautiful collars up the males were trying to impress the females.
Previously, there used to be many ruffs in Waalenburg, it was a well-known lek.
After 1985, the ruff disappeared as a breeding bird on the island. Natuurmonumenten hopes that ruffs will actually breed in Waalenburg this spring.
