Seawatching, september-november 1989
Sula , Volume 3 - Issue 4 p. 155- 156
Again, sites in Noord-Holland took the greatest share in seawatching hours. However, a reasonable number of hours were received from sites in Zuid-Holland (mainly Sep-Oct) and at the Waddensea islands (Terschelling, Ameland, Schiermonnikoog). Migrating divers were seen commonly in November. As usual, the most substantial movements were recorded from the Waddensea islands (notably Terschelling), including 440 individuals on 24 November. Hundreds of Great Crested Grebes per day were seen in the second half of November, while Red-necked Grebes ’peaked’ in the second half of October and early November.
