Summary, in English

Kallander H. 2011. Fishing flocks of Great Crested Grebes Podiceps cristatus consist of breeding birds. Ardea 99: 232-234. This note corrects a statement made in an earlier note on flock-fishing Great Crested Grebes Podiceps cristatus at the South Swedish Lake Krankesjon, namely that the flocks presumably consisted mainly of non-breeders. This has been proved wrong. The majority come from a loose colony and consist of birds during incubation recesses. Flock-fishing started around 1 May in 2008, 2009 and 2011, but not until the beginning of June in 2010. The reason for the late start in 2010 is unclear. Flocks formed soon after sunrise and dissolved at various times during the day. Only once was a fishing flock seen in early evening.
