A sea turtle clutch. A clutch of eggs is the group of eggs produced by birds, amphibians, or reptiles, often at a single time, particularly those laid in a nest. In birds, destruction of a clutch by predators (or removal by humans, for example the California condor breeding program) results in double-clutching. The technique is used to double ...
Avian clutch size should be proportional to breeding season resource productivity per breeding pair of birds. [10] This relationship has been found in a series of studies from Alaska and Costa Rica. [10] According to Ashmole's Hypothesis, the clutch size of resident birds is proportional to the level of competition with migrant birds. [11]

The average clutch size is four to six eggs per nest. Females lay one egg a day and incubation begins when the penultimate (second to last) egg is laid. Incubation lasts 15–16 days and the female is the main incubator, with some help from the male.
