- Abstract
Roosts and nesting sites of the endemic Galapagos Dove Zenaida galapagoensis were found on Santa Cruz, Daphne Major and Baltra Islands. At Las Grietas (0°45'26"S, 90°18'56"W), a tourist visitor site on Santa Cruz, roosts and a nesting site were found in 2017, in cracks and cavities of difficult access. The nest was observed for 24 days. Two adults incubated but the nest was abandoned in the late incubation phase. The nest, comprising twigs and dry leaves, contained two fertilised eggs and one broken shell, and the reason for abandonment is unknown. It contained no larvae or pupae of the parasite Philornis downsi. We observed up to ten doves at this site, including eight juveniles. In 2019, a second nest with two eggs was found in a hollow cactus trunk adjacent to the Charles Darwin Research Station on Santa Cruz. This nest was observed from incubation to fledging of both nestlings. We found 13 pupae of P. downsi in this nest, the first report of this invasive species parasitizing the Galapagos Dove. One nest was found on Daphne Major and another on Baltra Island, each with two eggs. These nests did not contain plant material and had no traces of P. downsi.
