Annual summary reports of Red Knot breeding ecology studies on the Seward Peninsula since 2011.

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...

Many of North America’s most rapidly declining avifauna breed in the boreal and alpine ecosystems of Alaska. Joint Base Elmendorf-Richardson (JBER) located in Anchorage, Alaska, provides critical nesting habitat for five avian Species of Special Concern (SOSC): Solitary Sandpiper Tringa solitaria, Lesser Yellowlegs Tringa flavipes, Olive-sided Flycatcher Contopus cooperi, Rusty Blackbird Euphagus carolinus and Blackpoll Warbler Setophaga striata. Joint Base Elmendorf-Richardson derived the Species of Special Concern list from the Birds of Conservation Concern (USFWS 2008) and the Department of Defense Mission-Sensitive Priority Bird Species (DoD PIF 2015) lists. Department of Defense Partners in Flight recognizes...

Principal to the management of migratory landbird resources is an understanding of their occurrence within the landscape. Baseline information on bird distribution is a primary need “to preserve a natural diversity and abundance of fauna and flora on refuge lands” (U.S. Fish and Wildlife Service [USFWS] 1993a). Documenting the occurrence and distribution of all migratory bird species is a priority of the USFWS’s action plan for developing a nongame bird inventory and monitoring strategy for National Wildlife Refuge system lands (USFWS 1993b ). Distribution and abundance information previously collected on National Wildlife Refuges has contributed to the description of distributional patterns of birds in Alaska....
