Data from: Introduced parasite changes host phenotype, mating signal and hybridisation risk: Philornis downsi effects on Darwin’s finch song

Sonia Kleindorfer, Georgina Custance, Katharina Peters & Frank J. Sulloway
Introduced parasites that alter their host’s mating signal can change the evolutionary trajectory of a species through sexual selection. Darwin’s Camarhynchus finches are threatened by the introduced fly Philornis downsi that is thought to have accidentally arrived on the Galapagos Islands during the 1960s. The P. downsi larvae feed on the blood and tissue of developing finches causing on average ~55 % in-nest mortality and enlarged naris size in survivors. Here we test if enlarged...
