Rangeland Songbirds

open access: yes, 2023
Abstract Songbirds that occur across the diverse types of North American rangelands constitute many families within the Order Passeriformes, and hundreds of species. Most are declining, and many are considered potential indicator species for rangeland ecosystems. We synthesized information on the natural and life history, habitat requirements,

Evolutionary origins of vocal mimicry in songbirds

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

Epigenetic‐Based Evidence for Distinct Effects of Age, Sex, and Experience in Developmental Critical Period Learning

open access: yesDevelopmental Neurobiology, Volume 86, Issue 3, July 2026.
ABSTRACT Although much is known about the encoding of experience, how the brain organizes neural circuits capable of learning and memory formation is largely unstudied. Canonical critical periods emerge from a convergence of maturation‐ and experience‐dependent processes.

Spring Migration of Songbirds

open access: yes, 2011
The St. Andrews Bird Banding Station has been running mist-netting programs to capture and record data on songbirds since 1989.

Spring migration of Blackpoll Warblers across North America

open access: yesAvian Conservation and Ecology, 2020
The awe-inspiring seasonal migrations of birds between breeding and wintering grounds has long attracted the interest of casual naturalists and professional ornithologists alike. Although new technologies improve our ability to follow individual migrants

Evaluation of an automated recording device for monitoring forest birds

open access: yesWildlife Society Bulletin, 2012
Monitoring of forest songbirds via auditory detections during point surveys can be enhanced by using preprogrammed recording devices. During May–July 2008, we compared boreal forest bird surveys conducted with SM‐1 bird song recorders (Wildlife Acoustics,

How important are quantum mechanical effects in controlling biological functions: Enzymes, electron transfer and bird navigation

open access: yesProtein Science, Volume 35, Issue 7, July 2026.
Abstract In light of the centennial of the Schrödinger equation, this article addresses the popular idea that quantum mechanical effects play an important role in biological systems. We start by defining what is qualified as a quantum effect. We then clarify the idea that quantum mechanical tunneling is a crucial factor in enzyme catalysis.

Data from: Female song is widespread and ancestral in songbirds

open access: yes, 2014
Bird song has historically been considered an almost exclusively male trait, an observation fundamental to the formulation of Darwin’s theory of sexual selection.

Flexible parental care in a songbird correlates with sex‐specific responses to seasonal phenology, mating opportunity and reproductive success

open access: yesJournal of Animal Ecology, Volume 95, Issue 7, Page 1178-1193, July 2026.
This population‐comparative study reveals that male and female parents respond differently to social and ecological conditions. This sex‐specific responsive strategy is related to the incongruent parental care systems across populations in Chinese penduline tits.

Migrating songbirds recalibrate their magnetic compass daily from twilight cues

open access: yes, 2004
Night migratory songbirds can use stars, sun, geomagnetic field, and polarized light for orientation when tested in captivity. We studied the interaction of magnetic, stellar, and twilight orientation cues in free-flying songbirds.
