Rangeland Songbirds
Songbirds that occur across the diverse types of North American rangelands constitute many families within the Order Passeriformes, and hundreds of...

Seasonal modulation of pectoralis muscle fiber type composition in migratory songbirds
The pectoralis major is the muscle required for migratory flight in songbirds, and has been believed to be exclusively composed of fast oxidative...
-
Songbirds initiate migratory flights synchronously relative to civil dusk
BackgroundEach spring and fall billions of songbirds depart on nocturnal migrations across the globe. Theory suggests that songbirds should depart on...

Pre-migratory flights in migrant songbirds: the ecological and evolutionary importance of understudied exploratory movements
Across the animal kingdom, from honeybees to cranes to beavers, exploratory movements to exploit resources, scout prospective territories, or...

Comparisons of songbirds on sale across online and physical markets in Indonesia
Unsustainable wildlife trade is a leading threat to biodiversity, not least in Southeast Asia where serious overexploitation of songbirds has...

Can Suttonella ornithocola entail a potential hazard to songbirds? A systematic review
Passeriformes populations have experienced a marked decline in number during the last decades. Several infectious agents have been described as key...

Covariation between protandry and sexual size dimorphism is age specific in songbirds
In many migratory songbirds, males arrive earlier at stopover sites and at the breeding grounds (‘protandry’) and older birds precede younger ones,...

Nest predation decreases with increasing nest height in forest songbirds: a comparative study
Nest predation is the most important factor responsible for nest failure in birds. Nest height may be a factor that affects the rate of nest...
-
Daily singing of adult songbirds functions to maintain song performance independently of auditory feedback and age
Many songbirds learn to produce songs through vocal practice in early life and continue to sing daily throughout their lifetime. While it is...

Atmospheric pressure predicts probability of departure for migratory songbirds
BackgroundWeather can have both delayed and immediate impacts on animal populations, and species have evolved behavioral adaptions to respond to...

The Role of the Basal Ganglia in the Development and Organization of Vocal Behavior in Songbirds
AbstractThe basal ganglia play an important role in the development of motor behavior; however, the mechanisms and specificity of their role in the...

Mendelian nightmares: the germline-restricted chromosome of songbirds
Germline-restricted chromosomes (GRCs) are accessory chromosomes that occur only in germ cells. They are eliminated from somatic cells through...
-
Fruit parasitism and abundance of a non-native insect pest affects abundances of some songbirds
Non-native insect pests can have significant effects on forest ecosystems. Forest fruit-targeting non-native insect pests may cause extensive damage...

The importance of time of day for magnetic body alignment in songbirds
Spontaneous magnetic alignment is the simplest known directional response to the geomagnetic field that animals perform. Magnetic alignment is not a...

Interspecific avoidance of song overlap in tropical songbirds: species-specific responses to acoustically similar and different intruders
AbstractTo ensure effective acoustic communication, signals should reach receivers in the least distorted form possible. Animals use various short-...
-
Factors predicting susceptibility of songbirds to nest predation by corvids
Despite the suggestion from several meta-analyses that nest predation is not limiting songbird populations, responses to experimental removal of nest...

Stopover territoriality in songbirds crossing the Sahara: aggression and energetics during migration
AbstractStopover territoriality, i.e., the defense and broadcast of an ephemeral home range during avian migration, is rare or perhaps overlooked....

Broadband 75–85 MHz radiofrequency fields disrupt magnetic compass orientation in night-migratory songbirds consistent with a flavin-based radical pair magnetoreceptor
The light-dependent magnetic compass sense of night-migratory songbirds can be disrupted by weak radiofrequency fields. This finding supports a...

Zebra finches increase social behavior in traffic noise: Implications for urban songbirds
Traffic noise is a pervasive pollutant that affects wildlife at individual and group levels through mechanisms such as disrupting communication,...
