Ecological and morphological determinants of evolutionary diversification in Darwin's finches and their relatives

Ecology and Evolution, 2020
Darwin's finches are a classic example of adaptive radiation, a process by which multiple ecologically distinct species rapidly evolve from a single ancestor.

Apparent effect of chronic Plasmodium infections on disease severity caused by experimental infections with Mycoplasma gallisepticum in house finches

International Journal for Parasitology: Parasites and Wildlife, 2017
An epidemic caused by a successful host jump of the bacterial pathogen Mycoplasma gallisepticum from poultry to house finches in the 1990s has by now spread across most of North America. M. gallisepticum causes severe conjunctivitis in house finches.

A Social Relations Model for the Colonial Behavior of the Zebra Finch

Journal of Methods and Measurement in the Social Sciences, 2010
A social relations model was developed for 5 years of behavioral recordings from a captive colony of Zebrafinches (Taeniopygia guttata). A quantitative ethogram was applied, using one-zero focal animal sampling on an ethologically comprehensive checklist

Colour Cues That Are Not Directly Attached to the Body of Males Do Not Influence the Mate Choice of Zebra Finches. [PDF]

PLoS ONE, 2016
Mate choice decisions of female zebra finches are generally thought to rely on the assessment of male quality, which includes the specific ornamentation of males.

Timing matters: age-dependent impacts of the social environment and host selection on the avian gut microbiota

Microbiome, 2022
Background The establishment of the gut microbiota in early life is a critical process that influences the development and fitness of vertebrates. However, the relative influence of transmission from the early social environment and host selection ...

The Field Metabolic Rate, Water Turnover, and Feeding and Drinking Behavior of a Small Avian Desert Granivore During a Summer Heatwave

Frontiers in Physiology, 2019
Global environmental change is leading to an increase in the frequency, intensity, and duration of extreme weather events, so effective environmental management requires an understanding not only of the physiological response of organisms to increased ...

Naris deformation in Darwin’s finches: Experimental and historical evidence for a post-1960s arrival of the parasite Philornis downsi

Global Ecology and Conservation, 2016
The rate of evolution depends on the strength of selection, which may be particularly strong for introduced parasites and their naive hosts. Because natural selection acts on phenotypes and because parasites can alter host phenotype, one fruitful ...

Influenza A(H7N9) Virus Transmission between Finches and Poultry

Emerging Infectious Diseases, 2015
Low pathogenicity avian influenza A(H7N9) virus has been detected in poultry since 2013, and the virus has caused >450 infections in humans. The mode of subtype H7N9 virus transmission between avian species remains largely unknown, but various wild birds

Relative Water Economy Is a Useful Index of Aridity Tolerance for Australian Poephiline Finches

Birds, 2022
We evaluate if the iconic Australian Zebra Finch (Taeniopygia guttata) has a unique physiology or if its metabolic, thermal and hygric physiology are similar to other Australian poephiline finches, by comparing it with three other species, the arid ...

Influence of human activity on gut microbiota and immune responses of Darwin’s finches in the Galápagos Islands

Avian Conservation and Ecology
Urbanization can influence many environmental factors that can affect the condition, immunity, and gut microbiota of birds. Over the past several decades, the Galápagos Islands of Ecuador have experienced increasing human activity, which has led to ...
