My research identifies 1) the terrestrial birds in Alaska that are most at-risk to environmental change and 2) the key habitats and resources these at-risk species require across their annual cycles and ranges to adapt to change.
I research the ecology and population dynamics of terrestrial birds (landbirds) in arctic and boreal ecosystems of Alaska and Canada. This large, yet poorly studied group of Federal Trust Species includes 142 breeding bird species in Alaska alone. My research produces information on status, trends, resource use, and limiting factors to identify 1) the landbird species most at risk to environmental change and 2) the key habitats and resources these species require to adapt to change. This information is used by resource managers in Alaska and Canada to prioritize limited resources for the species and habitats most in need of conservation. Many of my studies address bird populations at large spatial scales such as the state of Alaska, the western boreal forest biome, or entire species’ migratory ranges. These studies require considerable coordination among U.S. and Canadian collaborators to collect the data and often involve new approaches to analyze data compiled across multiple studies.

Point count offsets for estimating population sizes of north American landbirds
Bird monitoring in North America over several decades has generated many open databases, housing millions of structured and semi-structured bird observations. These provide the opportunity to estimate bird densities and population sizes, once variation in factors such as underlying field methods, timing, land cover, proximity to roads, and uneven spatial coverage are accounted for.

The Olive-sided Flycatcher (Contopus cooperi) is a steeply declining aerial insectivore with one of the longest migrations of any North American passerine. We deployed light-level geolocators and archival GPS tags on breeders in boreal Alaska to determine migratory routes, important stopovers and non-breeding locations.

Alaska is a land of extremes. The diversity of its avifauna reflects the heterogeneity of its landscape, with more than 500 species of birds recorded in the state. Species inhabiting primarily terrestrial habitats, known collectively as landbirds, constitute the largest and most ecologically diverse component of the Alaska avifauna.

Alaska provides habitat for 143 species of landbirds that occur regularly in the state, about half of which breed predominantly north of the border between the contiguous United States and Canada.

The arrangement of habitat features via historical or contemporary events can strongly influence genomic and demographic connectivity, and in turn affect levels of genetic diversity and resilience of populations to environmental perturbation.

Estimating population abundance is a challenging task complicated by the amount, type, and quality of available data. Conservationists have relied on design-based estimates from Partners in Flight (PIF), which primarily uses roadside data from the North American Breeding Bird Survey (BBS) to estimate populations sizes. However, the BBS was not designed to estimate population sizes. We developed moAuthorsPeter Solymos, Judith D Toms, Steven M. Matsuoka, Steven G. Cumming, Nicole K. S. Barker, Wayne E.

In June and July 2018 and July 2019 we surveyed birds on St. Matthew and Hall islands, isolated in the central Bering Sea. Our surveys were focused on the McKay’s Bunting (Plectrophenax hyperboreus), Rock Sandpiper (Calidris ptilocnemis ptilocnemis), and Pelagic Cormorant (Phalacrocorax pelagicus) but encompassed all birds and yielded 13 species and four subspecies new to the islands’ avifaunal liAuthorsBryce W.

Currently, the deployment of tracking devices is one of the most frequently used approaches to study movement ecology of birds.

We used conventional and finite mixture removal models with and without time-varying covariates to evaluate availability given presence for 152 bird species using data from point counts in boreal North America. We found that the choice of model had an impact on the estimability of unknown model parameters and affected the bias and variance of corrected counts.

Avian acoustic communication has resulted from evolutionary pressures and ecological constraints. We therefore expect that auditory detectability in birds might be predictable by species traits and phylogenetic relatedness.
