Integrative neural mechanisms for social communication of learned vocal behavior [PDF]

Frontiers in Integrative Neuroscience
Context-sensitive behaviors are crucial for the adaptive success of many organisms. Investigating neural processes that facilitate context-sensitive behavior requires knowledge of the molecular signaling and anatomical brain connectivity within and ...

Perception of Sex Differences in Black-Capped Chickadee (Poecile Atricapillus) Chick-A-Dee Calls [PDF]

Animal Behavior and Cognition, 2020
Black-capped chickadee (Poecile atricapillus) chick-a-dee calls differ acoustically depending on flock membership, individual identity, and species identity.

Relative Importance for Lincoln’s Sparrow (Melospiza lincolnii) Occupancy of Vegetation Type versus Noise Caused by Industrial Development

Frontiers in Ecology and Evolution, 2022
Anthropogenic noise can create an acoustic environment detrimental for animals that communicate using acoustic signals. Currently, most studies of noise and wildlife come from traffic noise in cities.

Two subspecies of a songbird migrant optimise departure from a coastal stopover with regard to weather and the route lying ahead

Journal of Avian Biology, 2023
Songbirds on migration spend a greater share of their travelling time at stopover sites in order to rest, recover and refuel compared to actively flying.

A method for estimating songbird abundance with drones

Drone Systems and Applications, 2022
Using drones to conduct airborne bioacoustics surveys is a potentially useful new way to estimate the abundance of vocal bird species. Here we show that by using two audio recorders suspended from a quadcopter drone it is possible to estimate distances ...

Parental influence on begging call structure in zebra finches (Taeniopygia guttata): evidence of early vocal plasticity [PDF]

Royal Society Open Science, 2015
Begging calls are signals of need used by young birds to elicit care from adults. Different theoretical frameworks have been proposed to understand this parent–offspring communication. But relationships between parental response and begging intensity, or

Categorizing the songbird market through big data and machine learning in the context of Indonesia’s online market

Global Ecology and Conservation, 2022
The songbird trade has been identified as a major threat to wild populations, and the bird market has now expanded to online platforms. The study explored the use of machine learning models as a monitoring framework; developed models for taxa ...

Habituation in songbirds [PDF]

Neurobiology of Learning and Memory, 2009
Songbirds respond to initial playback of a recorded conspecific song in numerous ways, from changes in gene expression in the brain to changes in overt physical activity. When the same song is presented repeatedly, responses have been observed to habituate at multiple levels: molecular, cellular and organismal.

Non-Invasive Monitoring of the Spatio-Temporal Dynamics of Vocalizations among Songbirds in a Semi Free-Flight Environment Using Robot Audition Techniques

Birds, 2021
To understand the social interactions among songbirds, extracting the timing, position, and acoustic properties of their vocalizations is essential. We propose a framework for automatic and fine-scale extraction of spatial-spectral-temporal patterns of ...
