Photographer and biologist Johan Hammar is photographing red kite (Milvus milvus) from a hide in southern Sweden. Europe holds about 95 % of the world population of red kites but in many countries they are decreasing. In Sweden it was almost extinct. Only 30 pairs remained in 1960. But thanks to nature conservation efforts there are now more than 1300 breeding pairs in Sweden.
However, there is a threat for this species of people poisoning raptors.
In Belgium there are about 200 nesting couples.
