Peruvian booby: Difference between revisions

Peruvian boobies breed throughout the year, however the main breeding season occurs during the austral spring-summer period (September to March). Pairs of birds may attempt to breed for a second time during the year depending on food availability. Peruvian boobies [[avian clutch size|clutch size]] varies from one to four eggs, but clutches are most frequently 2–3 in size. The eggs are pale blue in colour. Eggs are incubated for approximately 4 to 5 weeks, and both male and female parents share the nest attendance. The rearing period lasts about 3 months. Breeding success depends on food availability and is related to colony location, [[Group size measures|colony size]] and timing of breeding, among other variables.<ref name=zavalaga1/>
