High-throughput assessment of vocal modulation following chemogenetic inhibition in songbirds [PDF]
iScienceSummary: Chemogenetic tools that enable reversible manipulation of neuronal activity are essential for studying the neural bases of behavior, yet their application in songbirds remains limited.

Darwin's small and medium ground finches might have taste preferences, but not for human foods
Royal Society Open Science, 2022 Urbanization is rapidly changing ecological niches. On the inhabited Galapagos Islands, Darwin's finches consume human-introduced foods preferentially; however, it remains unclear why.

Where did the finch go? Insights from radio telemetry of the medium ground finch (Geospiza fortis)
Ecology and Evolution, 2022 Movement patterns and habitat selection of animals have important implications for ecology and evolution. Darwin's finches are a classic model system for ecological and evolutionary studies, yet their spatial ecology remains poorly studied. We tagged and

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

Urban living influences the nesting success of Darwin’s finches in the Galápagos Islands
Ecology and Evolution, 2021 Urbanization is expanding worldwide with major consequences for organisms. Anthropogenic factors can reduce the fitness of animals but may have benefits, such as consistent human food availability.

Current Biology, 2005 Why are they Darwin’s? Darwin was the first scientist to study them, and he made them famous. On his epoch-making visit to the Galapagos archipelago in 1835 he collected some specimens for museums, as did Robert FitzRoy, captain of the Beagle, and a couple of their shipmates.

Sex identification in embryos and adults of Darwin's finches.
PLoS ONE, 2021 Darwin's finches are an iconic example of adaptive radiation and evolution under natural selection. Comparative genetic studies using embryos of Darwin's finches have shed light on the possible evolutionary processes underlying the speciation of this ...

Ecotoxicology and Environmental Safety, 2021 Lead (Pb) is a pervasive global contaminant that interferes with sensitive windows for neurological development and causes oxidative damage to tissues. The effects of moderate and high exposure to Pb have been well-studied in birds, but whether low-level

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).

Auditory processing in the zebra finch midbrain: single unit responses and effect of rearing experience [PDF]
PeerJ, 2020 In birds the auditory system plays a key role in providing the sensory input used to discriminate between conspecific and heterospecific vocal signals. In those species that are known to learn their vocalizations, for example, songbirds, it is generally ...
