Maclear 1968 C. bairdi: 3 July there are 3 known 3-egg nests in the drum area now, and probably more. this late burst is amazing; there are young out as eggs are being laid. 4 July the two close nests remain with 3 eggs each. 5 July three eggs they shall be. Gabriel took one nest and added the eggs to the other. So it is clear now that late clutches are more likely to stop at 3 eggs. this is surely a factor in the 1965 situation.
