BiologyDuring the wet season, the Galapagos dove feeds largely on caterpillars and on flowers of the cactus Opuntia helleri (2) (5) (7). At other times, much foraging takes place on the ground, with the doves taking seeds of the bush Croton scouleri, often using the beak to dig up and uncover seeds. Other small seeds and fruits may be eaten, as well as cactus pulp, and the fly larvae and pupae that may be found inside cactus trunks and pads (2) (7). Feeding habits may differ between islands, with only some Galapagos doves reported to perch on Opuntia cacti and feed on the flowers, possibly due to differences in the rigidity of the cactus spines between islands (7). The Galapagos dove typically breeds between January and November, though breeding season may vary between islands (2) (5), and on Genovesa does not start until early February, after the rains (7). The nest itself is either placed on the ground, in rock cavities, or at around 75 centimetres above the ground, in an old nest of the Galapagos mockingbird, Mimus parvulus (2) (5) (7). Ground nests usually suffer higher predation than those above the ground (2) (7). Two eggs are normally laid, and hatch after an incubation period of 13 days. Fledging occurs at between 13 and 17 days, and the breeding pair may go on to nest again just 6 to 10 days later, sometimes raising up to three broods in one season (2) (7).
