This video is about black terns in the Netherlands.
On the Groene Strand beach on Voorne island, there were 284 nesting black-headed gull couples. Figures for other species there: common tern: 196; redshank: 4; ringed plover: 3; little ringed plover: 6; avocet: 17; oystercatcher: 7.
In the Voorhofsche polder, near Waddinxveen, in 2013 there were 45 black-tailed godwit nests; 34 northern lapwing nests; and 12 redshank nests. Common terns and tufted ducks nested there as well.
And in Staelduin nature reserve, a caterpillar was found of the rare sycamore moth.
