In our study about the breeding biology of the Blackish Oystercatcher Haematopus ater, conducted during 1991/92 breeding season, the laying period started at the end of the second week of October and finished at the end of November. Mean clutch size was 1.8 (sd= 0.4, n= 26, modal clutch size= 2), while the mean laying interval between the first and second eggs laid in the same clutch was 2.8 days (s.d.= 1.4, n= 16). The laying-hatching intervals averaged : 28 days (s.d.= 2.5, n= 11). Hatchings occured between the second week of November and the first week of December and mean hatching interval was 1.8 days (s.d.= 0.5, n= 5).
