Short Description
Hen harriers are medium-sized, relatively slender, light birds of prey. The iris is yellow. They swing through the air at low altitude.
The males are smaller than the females and weigh less than a wood pigeon. They are mostly blue-grey. The tips of the wings are black and sharply defined. The undersides of the rump, the belly and part of the wings are white. The iris of the young males is grey and turns yellow by autumn.
The females are clearly larger and heavier. They are mostly medium brown and partly black banded. They have a dark eye stripe and a distinct facial veil, which is narrowly whitish towards the neck. The iris of the young females is dark brown. In the 4th or 5th year it is amber and from the 7th year bright yellow.
The young are dark brown. The underside is beige brown.

In the city
Hen harriers are extremely rare in Germany and are almost only found on the Frisian Islands. They often hunt in meadows and fields and breed in moors, dunes, heaths and forest clearings.
Fun Facts
In Germany, the hen harrier is a very rare breeding bird. Fewer than 50 pairs were counted in 2013.
Hen harriers feed mainly on voles, but also on songbirds and waders, more rarely on lizards or insects.
Their flight behaviour while foraging is conspicuous and often described as swinging.
During courtship, the male often has prey with him while he shows off his flying skills to the female. The prey is presented to the female before mating takes place.
The nests are hidden on the ground. You should not get too close to them, as they are defended very aggressively.
