Transcript:
Slide 1: Oystercatchers are typically monogamous with both the mother and father heavily involved in raising chicks. But in a 1998 field study Dik Heg and Rob van Treuren reported a surprisingly high frequency of stable ‘trios’ forming. Two females and a male share a territory and nest. Together they act cooperatively to attend to their young and defend the territory
Slide 2 : Within the trio the two females regularly copulate with each other as well as the male. The female-female copulations are behaviourally indistinguishable from the male-female copulations, with the females adopting either the male or female ‘role’.
