Waterfowl mate, geese and swans sit brooding on their nests. The willow trees are in bloom, attracting swarms of bumblebees. Sap can be tapped from the birch trees. Stinging nettles and goutweed are fresh and perfect for making pesto. The first leverets are born and the first toads of the season flock to the ponds. At the end of the month, the cranes migrate northwards.
Now the bittern booms its drum-like sound by Hejresøen lake and Store Høj Sø lake - both locations have bird towers and hides from which you can observe birds - skylarks, blackbirds and starlings each have their own tune, and the lapwing is active. It is breeding time for the kestrel, and there are lots of goslings, ducklings and cygnets. The sheep, which are outside all year, start to lamb, and the cattle have returned to spend the summer months in Vestamager. The first tadpoles can be studied; on warm days, the grass snake basks in the sun; and the fallow stags shed their antlers. You can bring the antlers home if you find any.
The foxes venture outside their den to play. The nightingale sings, the cuckoo calls - it is an ornithological choir. The marsh harrier patrols the edge of the reed bed for food. The bees are busy and sand martins and swifts stuff themselves with insects while the first butterflies flutter around. The hawthorn and willow herb, which you can use like asparagus, are both in bloom. The foxes have had their cubs, while the common water frog breeds and croaks deafeningly day and night.
