The effects of dietary carotenoid supplementation and retinal carotenoid accumulation on vision-mediated foraging in the house finch. [PDF]

open access: yesPLoS ONE, 2011
BACKGROUND: For many bird species, vision is the primary sensory modality used to locate and assess food items. The health and spectral sensitivities of the avian visual system are influenced by diet-derived carotenoid pigments that accumulate in the ...

Whole genome sequencing and assembly of the house sparrow, Passer domesticus [PDF]

open access: yesGigaByte
The common house sparrow, Passer domesticus, is a small bird belonging to the family Passeridae. Here, we provide high-quality whole-genome sequencing data along with its assembly for the house sparrow.

Host Disease Tolerance Predicts Transmission Probability for a Songbird Pathogen [PDF]

open access: yesEcology and Evolution
Disease tolerance reduces the per‐pathogen fitness costs of infection for hosts and is an important component of host adaptation to pathogens. However, how disease tolerance affects host transmission potential is not well understood, especially because ...

House finch leg color changes with infection

open access: yesJournal of Avian Biology
In numerous animals, dramatic coloration (e.g. bright red or yellow) often indicates potential fitness, but it is less clear whether subtle coloration in the same individuals (e.g. grey or brown) could also encode such signals.

The Greater the Tilt, the Taller the Nest? The Effect of Solar Array Type on Bird Nest Architecture and Nest Microclimate [PDF]

open access: yesEcology and Evolution
The increasing demand for renewable energy has led to widespread installation of photovoltaic (PV) solar arrays, however, their ecological impacts, particularly on bird species, remain poorly understood.

Repeated evolution on oceanic islands: comparative genomics reveals species-specific processes in birds [PDF]

open access: yesBMC Ecology and Evolution
Understanding the interplay between genetic drift, natural selection, gene flow, and demographic history in driving phenotypic and genomic differentiation of insular populations can help us gain insight into the speciation process.

Ultrafast evolution and loss of CRISPRs following a host shift in a novel wildlife pathogen, Mycoplasma gallisepticum. [PDF]

open access: yesPLoS Genetics, 2012
Measureable rates of genome evolution are well documented in human pathogens but are less well understood in bacterial pathogens in the wild, particularly during and after host switches.

Antibiotic perturbation of gut bacteria does not significantly alter host responses to ocular disease in a songbird species [PDF]

open access: yesPeerJ, 2022
Bacterial communities in and on wild hosts are increasingly appreciated for their importance in host health. Through both direct and indirect interactions, bacteria lining vertebrate gut mucosa provide hosts protection against infectious pathogens ...

High virulence is associated with pathogen spreadability in a songbird–bacterial system

open access: yesRoyal Society Open Science, 2023
How directly transmitted pathogens benefit from harming hosts is key to understanding virulence evolution. It is recognized that pathogens benefit from high within-host loads, often associated with virulence.

Worlds at our fingertips:reading (in) What Remains of Edith Finch [PDF]

open access: yes, 2020
Video games are works of written code which portray worlds and characters in action and facilitate an aesthetic and interpretive experience. Beyond this similarity to literary works, some video games deploy various design strategies which blend gameplay ...
