Occurrence of Philornis bella Couri in nestlings of Tyrannus melancholicus Vieillot (Tyranninae) in the municipal district of Seropédica, Rio de Janeiro [PDF]

Biotemas, 2011
Five nestlings of Tyrannus melancholicus Vieillot, 1819, between nine (n = 2) and twelve days (n = 3) old, were studied from July to September in 2006. A total of 43 larvae was collected, of which 33 (76%) became adults and were identified as Philornis ...

Specificity within bird–parasite–parasitoid food webs: A novel approach for evaluating potential biological control agents of the avian vampire fly

Journal of Applied Ecology, Volume 59, Issue 8, Page 2189-2198, August 2022., 2022
Our results confirm previous laboratory studies indicating specificity by Conura annulifera and support the hypothesis that this species would produce few, if any, nontarget impacts if released into Galapagos to suppress populations of the Philornis downsi.

Functional traits and foraging behaviour: Avian vampire fly larvae change the beak and fitness of their Darwin's finch hosts

Functional Ecology, Volume 36, Issue 7, Page 1806-1817, July 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract The avian beak is a key morphological trait used for foraging. If parasites alter beak shape, we may expect changes in host foraging behaviour. Larvae of the avian vampire fly Philornis downsi cause naris enlargement in Darwin's finch nestlings when first and second ...

Avian disease surveillance on the island of San Cristóbal, Galápagos

Ecology and Evolution, Volume 11, Issue 24, Page 18422-18433, December 2021., 2021
In the Galápagos archipelago, two important wildlife diseases, avian pox (Avipoxvirus spp.) and avian malaria (Plasmodium spp. and related Haemosporidia), challenge endemic species. We find avian pox prevalence differs significantly with prevailing climate, being highest during El Niño events (~11% in 2016 and in 2019 versus <1% in the La Niña year of ...

Darwin’s finches habitually anoint their feathers with leaves of the endemic tree Psidium galapageium during the non‐breeding season

Ethology, Volume 127, Issue 10, Page 914-924, October 2021., 2021
Our study revealed that four species of Darwin's finches habitually anoint their feathers with leaves of the endemic tree Psidium galapageium, which contain volatiles with anti‐parasitic properties. We observed anointing most frequently in the morning when leaves are still wet and probably omit more volatiles.

Ecoimmunity in Darwin's finches: invasive parasites trigger acquired immunity in the medium ground finch (Geospiza fortis). [PDF]

PLoS ONE, 2010
BACKGROUND: Invasive parasites are a major threat to island populations of animals. Darwin's finches of the Galápagos Islands are under attack by introduced pox virus (Poxvirus avium) and nest flies (Philornis downsi).

Urban living influences the nesting success of Darwin’s finches in the Galápagos Islands

Ecology and Evolution, Volume 11, Issue 10, Page 5038-5048, May 2021., 2021
Urbanization is expanding worldwide with major consequences for organisms, understanding the trade‐offs of urbanization is of critical importance, particularly in environments with unreliable annual natural food availability, such as the Galápagos Islands.

Behavioural response to songs between genetically diverged allopatric populations of Darwin’s small tree finch in the Galápagos

Journal of Evolutionary Biology, Volume 34, Issue 5, Page 816-829, May 2021., 2021
Male song can signal species identity and male quality, and behavioural response to song can drive divergence or introgression. In this study, we describe clear differences in male song types and a weak signal of population genetic difference across two populations of small tree finch on two Galapagos Islands. Resident males responded to the song of an

New molecular data on subcutaneous Philornis (Diptera: Muscidae) from southern South America suggests the existence of a species complex

Revista Mexicana de Biodiversidad, 2016
The taxonomic identification of species in the genus Philornis Meinert (Diptera: Muscidae) has been based primarily upon analysis of morpho-logical characters. However, relying solely on morphology has led to frequent species misidentification.

New distribution records for Muscidae (Insecta: Diptera) in Latin America [PDF]

Check List, 2015
The geographical distribution of Muscidae from Latin America has been extended. The following eight genera, including 28 species, were collected: Cyrtoneurina (2 spp.), Cyrtoneuropsis (8 spp.), Dolichophaonia (1 sp.), Neomuscina (7 spp.), Ophyra (1 sp.),
