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

Ibis, 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 ...

Experimental demonstration of the fitness consequences of an introduced parasite of Darwin's finches. [PDF]

PLoS ONE, 2011
Introduced parasites are a particular threat to small populations of hosts living on islands because extinction can occur before hosts have a chance to evolve effective defenses.

Feather function and the evolution of birds

Biological 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

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.

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).

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.

Comparative metabolomics reveal developmental and ecological plasticity in the invasive parasite Philornis downsi (Diptera: Muscidae) from the Galapagos Islands. [PDF]

J Insect Sci
Abstract Invasive species pose a critical threat to biodiversity, often endangering ecologically naive endemic fauna. The avian vampire fly, Philornis downsi Dodge & Aitken, 1968 (Diptera: Muscidae), a semi-hematophagous ectoparasite introduced to the Galápagos Islands, has caused severe declines in endemic and native bird ...
