Evolutionary origins of vocal mimicry in songbirds

open access: yesEvolution Letters, 2018
Vocal learning is an important behavior in oscines (songbirds). Some songbird species learn heterospecific sounds as well as conspecific vocalizations.

Comparing bird communities within shrubby transmission line rights-of-way managed by mowing or by selective herbicide application in Maine and New Hampshire [PDF]

open access: yes, 2018
In the northeastern U.S., thousands of miles of shrub-dominated transmission line rights-of-way (ROW) extend across the landscape and provide some of the largest and most stable shrubland habitats in the region.

Prothonotary warbler nestling growth and condition inresponse to variation in aquatic and terrestrial preyavailability [PDF]

open access: yes, 2016
Aquatic prey subsidies entering terrestrial habitats are well documented, but little is known about the degree to which these resources provide fitness benefits to riparian consumers.

Thresholding species distribution models: Simple approaches for land‐use planning in multifunctional landscapes

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Species distribution models (SDMs) are often used to understand changes to species' distributions and their habitats under different land‐use scenarios, enabling decision makers to prioritize areas for management efforts and balance environmental conservation with socio‐economic demands on the landscape.

The songbirds as an inspiration for Byzantine kratēmata [PDF]

open access: yesMuzikologija
Byzantine kratēmata, widely known as the terrirem, as part of other, broader musical works, date approximately back to the eleventh-twelfth century. A small group of four kratēmata are named after birds (Aēdhon - Luscinia megarhynchos, Potamis -

CISO: Species distribution modelling Conditioned on Incomplete Species Observations

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Species distribution models (SDMs) are widely used to predict species' geographic distributions, serving as critical tools for ecological research and conservation planning. Typically, SDMs relate species occurrences to environmental variables representing abiotic factors, such as temperature, precipitation, and soil properties.

Urbanization and brood parasitism affect growth, but not free amino acid concentrations in nestling song sparrows (Melospiza melodia)

open access: yesFrontiers in Bird Science
Urbanization is projected to grow rapidly in the coming decades. Several consequences of this form of anthropogenic change for ecosystems and individuals are described by the fields of urban ecology and urban ecophysiology, respectively.

The Development of Structured Vocalizations in Songbirds and Humans: A Comparative Analysis

open access: yesTopics in Cognitive Science, 2019
Humans and songbirds face a common challenge: acquiring the complex vocal repertoire of their social group. Although humans are thought to be unique in their ability to convey symbolic meaning through speech, speech and birdsong are comparable in their ...

Stable Isotope Analysis as a Tool to Prevent Illicit Wildlife Trade of Songbirds in Brazil

open access: yesAnimal Conservation, EarlyView.
Feather isotopes provide clear differences between wild and captive songbirds in Brazil. Combining multiple isotopes improved classification accuracy and revealed individuals falsely declared as captive‐bred. These results demonstrate the potential of isotope analysis to detect wildlife laundering in the bird trade.
