Een weekje Cap Gris Nez in het voorjaar van 1985

From 24 April through 1 May 1985 seawatches were carried out at Cap Gris Nez (France) recording seabirds and shorebirds. Most counts took place during the first hours of the day (table 1). After a week of stormy weather with northeasterly winds the wind changed to SW during the counting period and large numbers of birds passed by. The weather conditions during the counts are specified in table 2, which presents the results of the seawatches. Of all birds recorded only a 0.37% flew south. These numbers are indicated between brackets in table 2. All other birds flew NE and all average numbers calculated only concern these. Large numbers were noted of divers (260 ind., 8.4/hour). Common Scoters (573 ind., 18.65/hour), Velvet Scoters (1135 ind., 36,8S/hour). Bar-tailed Godwits (3444 ind., 111.7/hour). Little Gulls (1038 ind., 33.7/hour). Sandwich Tern (1606 ind., 52.1/hour) and Common and Arctic Tern (5155 ind., 167.2/hour).
