First report of the Philornis torquans complex in adult birds in continental Ecuador: Is parasitism by Philornis being underestimated?

open access: yesRevista Mexicana de Biodiversidad, 2022
Myiasis by Philornis is a usual phenomenon in Neotropical birds. Philornis larvae are hematophagous and are known to affect both nestlings and adults. Still, parasitism in adults seems opportunistic and has been poorly studied compared to parasitism in ...

Genomic Introgression Between Critically Endangered and Stable Species of Darwin's Tree Finches on the Galapagos Islands. [PDF]

open access: yesEvol Appl
ABSTRACT Natural hybridisation among rare or endangered species and stable congenerics is increasingly topical for the conservation of species‐level diversity under anthropogenic impacts. Evidence for beneficial genes being introgressed into or selected for in hybrids raises concurrent questions about its evolutionary significance.

Life‐stage and sex influence Philornis ectoparasitism in a Neotropical woodpecker Melanerpes striatus with essential male parental care

open access: yesIbis, Volume 165, Issue 4, Page 1235-1250, October 2023., 2023
The nestlings of many Neotropical bird species suffer from Philornis (Diptera: Muscidae) ectoparasitism. Although nestlings are typically considered the intended targets, recent work indicates that Philornis infest adult birds more frequently than previously appreciated, yet few studies have concurrently surveyed nestlings and adults for Philornis in ...

Feather function and the evolution of birds

open access: yesBiological Reviews, Volume 98, Issue 2, Page 540-566, April 2023., 2023
ABSTRACT The ability of feathers to perform many functions either simultaneously or at different times throughout the year or life of a bird is integral to the evolutionary history of birds. Many studies focus on single functions of feathers, but any given feather performs many functions over its lifetime. These functions necessarily interact with each

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

open access: yesBiotemas, 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

open access: yesJournal 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

open access: yesFunctional 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 ...

Life Cycle and Development of Diptera [PDF]

open access: yes, 2021
Diptera, or true flies, are of considerable economic importance, as these flies have a valuable role as scavengers, parasitoids and predators of other insects, pollinators, food for predators, bio-indicators of water quality, and tools for scientific ...

Avian disease surveillance on the island of San Cristóbal, Galápagos

open access: yesEcology 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

open access: yesEthology, 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.
