Shorebirds are among the most rapidly declining species in North America (Rosenberg et al. 2019), with many long-distance migrants experiencing the greatest declines (Environment Canada 2020). Nonetheless, not all shorebirds are declining and there may be differences among species and populations using different migratory routes. For instance, previous meta-analyses have suggested that shorebirds using the Mid-Continental Flyway are experiencing more rapid declines than those using the Pacific or Atlantic flyways (Thomas et al. 2006). At the same time, within a species, more northerly breeding populations are experiencing greater phenological mismatches and lower reproductive success than southerly ones (Kwon et...

Boreal wetland birds are among the continent’s most rapidly declining avifauna. However, many of these declining species still breed commonly on military lands in Alaska. We propose to survey these species, as well as, additional boreal wetland obligates at breeding sites on Eielson Air Force Base (AFB) and then track migratory movements throughout the annual cycle. Our surveys aim to identify important wetland features for conservation and levels of fragmentation that may reduce bird breeding numbers. Our tracking of birds during migration will identify habitats for conservation at key stopover and wintering areas, and therefore allow conservation on military lands in Alaska to be directly linked to conservation...

Upland Sandpiper is one of many declining shorebird species (-4.6%/year in Alaska; Ziolkowski et al. 2023) which breed on military and adjacent lands in Alaska. Western and eastern populations are small and unstable, and the species is endangered at the state level in several eastern U.S. states (Houston et al. 2023). Though there has been considerable work with Upland Sandpipers in their core, central U.S. breeding areas, this is the first dedicated study of Upland Sandpipers in Alaska. The objectives are to resight, band, and track Upland Sandpiper at breeding sites in Delta Junction, AK and Donnelly Training Area (TA 501 & TA 511) to estimate vial rates, determine migratory connectivity, and determine important...

Shorebirds are a group of predominantly migratory birds that are declining at an alarming rate; many of them have declined by more than 50% since 1970 and 13 are of federal conservation concern. With staggeringly long, trans-hemispheric migrations along each of North America’s migratory flyways — distinct corridors that divide North America longitudinally — shorebirds breeding in the Arctic and sub-Arctic and wintering in Central and South America encounter a multitude of threats during their annual cycles. This study aims to track the fall migration of a suite of species from their breeding sites across Alaska to the southern extent of their respective ranges and address how differences in migratory connectivity...

Multiple lines of evidence suggest that the Gray-headed Chickadee (Poecile cinctus lathami), a population endemic to Alaska and northwestern Canada, has declined and/or been extirpated from locations where they were considered historically common. In contrast, the Boreal Chickadee, a native congener, has recently colonized locations where Gray-headed Chickadees once occurred. This project focuses on whether hybridization (and subsequent transfer of genetic material from one species into another with continued breeding events overtime) between these two closely related chickadee species may be responsible for Gray-headed Chickadee declines. Specifically, our objectives are to: 1) Conduct call-playback surveys to...
