Avian Demographic Data from the Colville River Delta, Alaska Avian Demographic Data from the Colville River Delta, Alaska
This data release contains multiple tables with information on avian demographics collected at the Colville River Delta, Alaska, 2011-2018. Researchers with the U.S. Geological Survey began studying the reproductive ecology of birds at a site on the Colville River near the Beaufort Sea coast in 2011. Researchers monitored the nests of geese, shorebirds, and landbirds at this study site
Body Composition of Bar-tailed Godwits (Limosa lapponica) Body Composition of Bar-tailed Godwits (Limosa lapponica)
These data are in one table with measures of the external morphology and internal organ and muscle groups collected from Bar-tailed Godwits.
Tracking Data for Whimbrels (Numenius phaeopus) Tracking Data for Whimbrels (Numenius phaeopus)
This data release includes 2 child items with tracking data for Whimbrels, a shorebird found throughout tundra and boreal habitats of Alaska during the summer and winters along the coasts of the continental U.S., and central and South America. Child Item 1: "Argos Satellite Tracking Data for Whimbrels (Numenius phaeopus) - Processed Data" -- Quality-controlled data collected from Argos...
Goose Mass and Vegetation Data, Colville River Delta, Alaska, 2012-2017 Goose Mass and Vegetation Data, Colville River Delta, Alaska, 2012-2017
This data release contains three tables of information from the Colville River Delta, Alaska (CDR): offtake of Carex subspathacea (2012-2014), standing crop of C. subspathacea (2012-2014), and snow goose and black brant gosling mass data (2012-2017). Data were collected as part of the USGS Changing Arctic Ecosystems Initiative to understand the response of wildlife to rapid physical...
Normalized Difference Vegetation Index, Biomass, and Nitrogen Content of Goose Forage, Northern Alaska, 2011-2018 Normalized Difference Vegetation Index, Biomass, and Nitrogen Content of Goose Forage, Northern Alaska, 2011-2018
This data set contains four tables of information regarding the sampling of plant biomass, nitrogen, cumulative thaw degree days, precipitation, and Normalized Difference Vegetation Index (NDVI) for the Colville River Delta and Point Lonely area of northern Alaska.
Information from Bird Nests Monitored on the Colville River Delta, Alaska, 2011-2018 Information from Bird Nests Monitored on the Colville River Delta, Alaska, 2011-2018
This dataset contains nesting information for birds breeding at a site on the Colville River, Alaska, 2011-2018. Nests were located during area searches conducted by biologists, and standardized information on each nest was collected following protocols of the Arctic Shorebird Demographic Network (Brown et al. 2014).

Shorebird research at the U.S. Geological Survey Alaska Science Center Shorebird research at the U.S. Geological Survey Alaska Science Center
Shorebirds—which include sandpipers, plovers, and oystercatchers—are perhaps best known by their presence on sandy beaches, running along the water’s edge while they probe for food. But they are probably less recognized for their impressive long-distance migrations. Millions of individuals travel from across the globe to breed throughout Alaska each spring, making these birds a familiar...

Through thick and thin: Sexing Bristle-thighed Curlews Numenius tahitiensis using measures of bill depth Through thick and thin: Sexing Bristle-thighed Curlews Numenius tahitiensis using measures of bill depth
Birds often exhibit diagnostic traits that differ among individuals of the same species with regard to factors like sex, age, or breeding status. Shorebirds exhibit a wide diversity of colors, shapes, and sizes of their bills, and these traits are commonly used to determine the sex of individuals. In curlews (genus Numenius), length alone accurately separates the sexes in some species...

Factors promoting the recolonization of Oahu, Hawaii, by Bristle-thighed Curlews Factors promoting the recolonization of Oahu, Hawaii, by Bristle-thighed Curlews
Suitable habitat for Arctic-breeding migratory shorebirds is decreasing at their traditional wintering islands and atolls in the Central Pacific Flyway (i.e., Oceania) due to habitat degradation, reclamation, and sea-level rise. To maintain the size and resiliency of their populations, migratory shorebirds will need to expand their winter ranges by either colonizing new sites or...

Shorebird subsistence harvest and indigenous knowledge in Alaska: Informing harvest assessment and management, and engaging users in shorebird conservation Shorebird subsistence harvest and indigenous knowledge in Alaska: Informing harvest assessment and management, and engaging users in shorebird conservation
Limited data on harvest and population parameters are major impediments to assess shorebird harvest sustainability. Because of sharp declines in shorebird populations, timely conservation efforts require approaches that account for uncertainty in harvest sustainability. We combined harvest assessment and ethnographic research to better understand shorebird conservation concerns related...

Technical comment on “Global pattern of nest predation is disrupted by climate change in shorebirds” Technical comment on “Global pattern of nest predation is disrupted by climate change in shorebirds”
Kubelka et al. (Report, 9 November 2018, p. 680-683) claim that climate change has disrupted patterns of nest predation in shorebirds. They report that predation rates have increased since the 1950s, especially in the Arctic. We describe methodological problems with their analyses and argue that there is no solid statistical support for their claims.

Alaska Shorebird Conservation Plan, Version III Alaska Shorebird Conservation Plan, Version III
In recognition of declines among perhaps half of Alaska’s breeding shorebirds, ongoing or emerging threats to shorebirds and their habitats, and considerable knowledge of Alaska’s shorebirds acquired over the past decade, the Alaska Shorebird Group decided that the Alaska Shorebird Conservation Plan was due for updates. Similar to Version II (2008), we structured the plan in two parts...
