G. Jimenez-Uzcategui: "The taxonomy of this species has been very confusing: Ridgway (1896) mentions five “species” (considered even by most other authors of the time as subspecies): nanus, dubius, intercedens, carolensis, and abingdoni (the latter three of which he himself described). Two subspecies were recognized: P. r. nanus (Gould 1841), occurring on most islands, and P. r. dubius (Gould 1841), from San Cristóbal. Salvin (1876), but, suggested that specimens of P. r. dubius were instead juvenile males of P. r. nanus (Wiedenfeld 2006). However, the last study mitochondrial and nuclear genetic, data, morphology, and behavior suggest that Galápagos forms should be elevated to two full species: P. nanus Gould, 1838 (Galápagos Vermilion Flycatcher) and P. dubius Gould, 1839 (San Cristóbal Vermilion Flycatcher) (Carmi, etal. In press.)".
Preference for an altitude zone in Galapagos: Dry zone - high altitude dry zone
Habitat preferences: Bosques abiertos, bosques, zona de Scalesia, bosques nativos de Zanthoxylum, bosques de guayaba introducida.
Feeding preferences: Sit and wait predator, which perches on exposed branches and flies for insects, flies and moths. But it may also hunt for arthropods, such as spiders and caterpillars, ranging from tiny aphids to 4cm large caterpillars.
Trophic role: Carnivorous
Reproduction mode: Exclusively sexual
Reproductive biology: A year-round a territorial species; the male does conspicuous song flights; its song is rather short and weak. Pairs stay together for at least one season. Breeding takes place during the warmer part of the year but has been observed breeding as early as October. Mostly the female builds a cup nest of moss, lichens, and fine fibers, feathers from other species, placed 2 to 10m high in a fork or on a horizontal branch. The female lays 2-3 eggs and incubates while the male helps in feeding her. Both sexes feed the chicks; fledglings stay with their parents approximately 4 weeks after leaving the nest.
Distribution classification: Eutropical
Distribution map of specimen collection localities or observation records for this species in our collections database.
Distribution: Breeds on most main islands except San Cristóbal (other species: P. dubius Gould, 1839) , Santa Fe, Rábida, Wolf, Española, Darwin, Genovesa, Baltra, because there are few or no recent records.
