Forest Policy Scenario Analysis: Sensitivity of Songbird Community to Changes in Forest Cover Amount and Configuration

open access: yesAvian Conservation and Ecology, 2007
Changes in mature forest cover amount, composition, and configuration can be of significant consequence to wildlife populations. The response of wildlife to forest patterns is of concern to forest managers because it lies at the heart of such competing ...

Prenatal Valproic Acid Exposure Affects Song Learning in Zebra Finches: A Potential Model for Vocal Development in Autism

open access: yesLife
Autism spectrum disorder (ASD) encompasses a range of neurodevelopmental conditions characterized by impairments in social abilities and communication. Studying appropriate animal models can enhance our understanding of the neural mechanisms underlying ...

Crop type influences edge effects on the reproduction of songbirds in sagebrush habitat near agriculture

open access: yesAvian Conservation and Ecology, 2014
Extensive fragmentation of the sagebrush shrubsteppe of western North America could be contributing to observed population declines of songbirds in sagebrush habitat.

Short-term weather patterns influence avian body condition during the breeding season

open access: yesFrontiers in Ecology and Evolution, 2023
Despite a large body of literature investigating the effects of long-term climate trends on birds, the effects of short-term weather on individual body condition are less established.

The Feasibility of Counting Songbirds Using Unmanned Aerial Vehicles

open access: yes, 2017
Obtaining unbiased survey data for vocal bird species is inherently challenging due to observer biases, habitat coverage biases, and logistical constraints.

A hypothesis on improving foreign accents by optimizing variability in vocal learning brain circuits [PDF]

open access: yes, 2015
Rapid vocal motor learning is observed when acquiring a language in early childhood, or learning to speak another language later in life. Accurate pronunciation is one of the hardest things for late learners to master and they are almost always left with

A loss of heterozygosity, a loss in competition? The effects of inbreeding, pre‐ and postnatal conditions on nestling development

open access: yesEcology and Evolution, 2016
The early developmental trajectory is affected by genetic and environmental factors that co‐depend and interact often in a complex way. In order to distinguish their respective roles, we used canaries (Serinus canaria) of different genetic backgrounds ...

Abcam Monoclonal Egr-1 ab133695 is an effective primary antibody replacement for Santa Cruz sc-189 polyclonal Egr-1 in songbirds

open access: yesHeliyon, 2019
Background: The immediate early gene ZENK (acronym zif268, Egr-1, NGFI-A, krox24) has been used extensively in songbird research (Mello et al., 1992; Jarvis and Nottebohm, 1997), as well as other research areas.

Songbirds can learn flexible contextual control over syllable sequencing

open access: yeseLife, 2021
The flexible control of sequential behavior is a fundamental aspect of speech, enabling endless reordering of a limited set of learned vocal elements (syllables or words). Songbirds are phylogenetically distant from humans but share both the capacity for

Early Auditory Experience Modifies Neuronal Firing Properties in the Zebra Finch Auditory Cortex

open access: yesFrontiers in Neural Circuits, 2020
Songbirds learn to sing much as humans learn to speak. In zebra finches, one of the premier songbird models, males learn to sing for later courtship through a multistep learning process during the developmental period.
