Predation risk associated with nesting in gull colonies by two Aythya species: observations and an experimental test
To reduce nest predation certain duck species nest in association with more aggressive species. For instance, Pochard Aythya ferina and Tufted Duck Aythya fuligula often nest in association with small larids, such as the Black‐headed Gull Larus ridibundus . I studied nest predation, nesting associat...
