Little tern
The little tern is the smallest European tern and also a very brave bird. It chooses to make its nest in places where other birds wouldn't dare. That limits any competition. Little terns often lay their eggs in nothing more than a hollow in the sand. By nesting in such risky places, the colonies often lose eggs during high tide and the chicks turn numb due to a lack of shelter. By nesting in small colonies, they spread the risk.

Up till the 1960s, there were 1000 pairs of little terns nesting in the Netherlands. However, suitable undisturbed nesting areas became scarse with the arrival of the Delta Works, the expansion of the harbor of Rotterdam and the massive increase in beach recreation. In addition, pollution of the seawater contributed to the decline in the population, reaching a low in 1970 with no more than 100 nesting pairs.
In 1993, the Dutch Bird Society began a campaign for the little terns: 'Actieplan Dwergstern’. The purpose was to raise the minimum number of nesting pairs in the country to 600. It was a success. In 2008, the nesting population in the Netherlands was 850 pairs, of which more than 50% in the delta region. Texel had 226 pairs in 2009.
