Notornis, 22 (4), 295-301

P.J. Dilks (1975)

Article Type: Paper

Feral pigeons bred in all months of the year but did less well in March when food was short. The most common clutch size, two, was also the most productive, 50% of eggs producing flying young. Clutches of one and four had significantly lower productivity. Clutches of one accounted for 15% of total clutches, three for 1% and four for 3%. Man seemed to be the only important predator of adult birds.
