Island songbirds as windows into evolution in small populations

open access: yesCurrent Biology, 2020
Due to their limited ranges and inherent isolation, island species have long been recognized as crucial systems for tackling a range of evolutionary questions, including in the early study of speciation [1,2].

Categories, concepts, and calls : auditory perceptual mechanisms and cognitive abilities across different types of birds. [PDF]

open access: yes, 2013
Although involving different animals, preparations, and objectives, our laboratories (Sturdy's and Cook's) are mutually interested in category perception and concept formation.

A neonicotinoid insecticide reduces fueling and delays migration in songbirds

open access: yesScience, 2019
Hazardous delays Neonicotinoids are a widely used group of pesticides that have been shown to have negative impacts on an increasing number of species, most notably pollinators. Eng et al. tested how exposure to these compounds influenced the behavior of

Songbirds can learn flexible contextual control over syllable sequencing

open access: yesbioRxiv, 2020
The flexible control of sequential behavior is a fundamental aspect of speech, enabling endless reordering of a limited set of learned vocal elements (i.e. syllables or words).

Parental benefits and offspring costs reflect parent–offspring conflict over the age of fledging among songbirds

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2020
Significance Parent–offspring conflict has explained a variety of ecological phenomena across animal taxa, but its role in mediating when songbirds fledge remains controversial.

Testosterone affects song modulation during simulated territorial intrusions in male black redstarts (Phoenicurus ochruros) [PDF]

open access: yes, 2012
Although it has been suggested that testosterone plays an important role in resource allocation for competitive behavior, details of the interplay between testosterone, territorial aggression and signal plasticity are largely unknown.

To transduce a zebra finch: interrogating behavioral mechanisms in a model system for speech. [PDF]

open access: yes, 2017
The ability to alter neuronal gene expression, either to affect levels of endogenous molecules or to express exogenous ones, is a powerful tool for linking brain and behavior. Scientists continue to finesse genetic manipulation in mice.

Migration of North Asian Passerines

open access: yesАмурский зоологический журнал, 2022
The East Asian-Australasian bird migration system is one of the most species-rich migration systems, nevertheless, we have very little information on the migration of the species that use the Asian-Australasian Flyway.

Scale and Sensitivity of Songbird Occurrence to Landscape Structure in a Harvested Boreal Forest

open access: yesAvian Conservation and Ecology, 2005
To explore the spatial scales at which boreal forest birds respond to landscape structure and how those responses are influenced by forest harvest, we quantified the relationship between amounts of forest in the landscape at multiple spatial scales and ...
