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 ...

Passeromyia Rodhain & Villeneuve and Philornis Meinert are the only known Muscidae whose larvae are parasites of birds. Passeromyia is known from the Old World and Philornis from the New World. Opinions on the relations between these two genera and their

Parental care in the Small Tree Finch Camarhynchus parvulus in relation to parasitism and environmental factors. [PDF]
The parental food compensation hypothesis suggests that parents may compensate for the negative effects of parasites on chicks by increased food provisioning. However, this ability differs widely among host species and may also depend on ecological factors such as adverse weather conditions and habitat quality.

Evidence for rapid downward fecundity selection in an ectoparasite (Philornis downsi) with earlier host mortality in Darwin's finches. [PDF]
Frontal view of a female Philornis downsi, a myasis‐causing paraiste of Darwin's finches, whose body size, abdomen size, and fecundity have decreased c. 30% across 12 years as nestling hosts die at an ever younger age. Photo by Bradley Sinclair. Abstract Fecundity selection is a critical component of fitness and a major driver of adaptive evolution ...

Under adverse conditions, older small tree finch males (Camarhynchus parvulus) produce more offspring than younger males. [PDF]
In many bird species, females paired with older males have a higher breeding success. Small tree finches are heavily affected by an invasive nest parasite. Nests of older males had more fledglings than those of younger males. However, the difference in breeding success disappeared when parasites were experimentally reduced with the insecticide ...

First record of Philornis glaucinis Dodge & Aitken, 1968 (Diptera: Muscidae) in Thalurania glaucopis Gmelin, 1788 (Aves: Trochilidae) [PDF]
From the groups causing myiasis, the genus Philornis Meinert, 1890 appears as the only representative of the family Muscidae, obligatorily associated with birds.

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

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
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
