Remove ectoparasites from nests to increase survival or reproductive success
A replicated, controlled study from 1982-1989 in Nebraska, USA (Brown & Brown 1999) found that survival of cliff swallow Petrochelidon pyrrhonota chicks from nests treated with Naled (an organophosphate insecticide) did not decline with later laying date, unlike control nests. The number of chicks surviving to ten days old was also higher for fumigated nests than control nests (1.75-2.80 chicks/nest survived to ten days old in 15 fumigated nests vs. a maximum of 2.50 chicks/nest, declining to <1.25 chicks/nest for clutches laid after 25th June for non-fumigated nests).
