Listening to the City: Evaluating BirdNET Reliability and Bias in Urban Bird Community Assessments

Remote Sensing in Ecology and Conservation, EarlyView.
BirdNET substantially overestimates urban bird species richness, but seasonal filtering and local calibration meaningfully improve classification precision. ABSTRACT BirdNET is increasingly used for passive acoustic monitoring (PAM), yet its reliability in urban environments that have high levels of anthropogenic noise remains poorly understood.

Joint analysis of structured and semi-structured community science data improves precision of relative abundance but not trends in birds

Scientific Reports, 2022
Estimating absolute and relative abundance of wildlife populations is critical to addressing ecological questions and conservation needs, yet obtaining reliable estimates can be challenging because surveys are often limited spatially or temporally ...

Wildlife management in the United States – thoughts on evolving to better address species overabundance and disease transmission

Wildlife Society Bulletin, EarlyView.
Management options and actions are important for responsibly working to keep populations of sometimes overabundant species of invasive and native wildlife at levels that keep damage (e.g., agricultural, environmental, human health and safety) and disease (e.g., species specific, shared with livestock, zoonotic) associated with them at acceptable levels.

eBird observations of the Myioborus ornatus superspecies.

, 2021
eBird considers Myioborus ornatus to be one species, but [1] treat it as two separate species: Myioborus ornatus in the Eastern Andes (orange polygon) and Myioborus chrysops in the Central and Western Andes (brown polygon).

The spatiotemporal effects of seasonal migration on passerine phylogenetic community structure

Journal of Animal Ecology, EarlyView.
The effects of mobile organisms on community structure and assembly are poorly understood. Distributional data show that seasonal migration in birds drives a complex continental redistribution of phylogenetic community structure. These results reveal a dynamic continental landscape of community structure directed by the movements of migratory birds ...

Does "task difficulty" explain "task-induced deactivation"?

Frontiers in Psychology, 2012
The "default mode network" is commonly described as a set of brain regions in which activity is suppressed during relatively demanding, or difficult, tasks. But what sort of tasks are these?

Museomics Deciphers the Phylogeographic Differentiation and Conservation Status of a Montane Pheasant

Integrative Zoology, EarlyView.
Museum specimens provide a rich source of historical DNA, enabling insights into phylogenetic relationships and demographic history of the endangered Koklass Pheasant. Our findings uncovered a previously unrecognized population in Guizhou province and highlighted elevated extinction risk in populations from Anhui province and Southern China, informing ...

Improving Data Quality in eBird- the Expert Reviewer Network [PDF]

Biodiversity Information Science and Standards, 2018
eBird is a global citizen science project that gathers observations of birds. The project has been making a considerable contribution to the collection and sharing of bird observations, even in the data-poorest countries, and is accelerating the accumulation of bird records globally. On 22 March 2018 eBird surpassed ½ billion bird observations.
