Abstract
SUMMARY Roberts, P. E., F. D. Merritt and R. B. Floyd. 1974. Wedge-tailed Shearwaters on Muttonbird Island, Coffs Harbour, NSW. Emu 75: 19–22. Wedge-tailed Shearwaters returned to Muttonbird Island in the first nine days of August in 1971 and 1972. Laying extended from 21 November to 3 December (mean date 27 November), with no statistically significant differences between 1971 and 1972. Incubation was shared by both partners in shifts of one to five days, started by either sex, for a total of 52–54 days. Hatching is estimated to occur about 19 January ± one week. The last of the chicks departed about 10 May.Keywords
