This data set is composed of data collected from an experimental study inoculating mallard ducks (Anas platyrhynchos) with Saxitoxin and associated control ducks. Data includes the specific of inoculation, observational behavioral data, daily weights, dosing, results of inoculation, testing of samples collected throughout the study, and necropsy results.

The Kittlitz’s Murrelet (Brachyramphus brevirostris) is a small, non-colonial seabird endemic to marine waters of Alaska and eastern Russia that may have experienced significant population decline in recent decades, in part because of low reproductive success and terrestrial threats. Although recent studies have shed new light on Kittlitz’s Murrelet nesting habitat in a few discrete areas, the location and extent of other possible nesting areas throughout most of its range remains unclear. This data release consists of (1) nest locations for the Kittlitz’s Murrelet (2) potential Kittlitz’s Murrelet nesting habitat. These data support the following publication (available online early): Jonathan J. Felis, Michelle...

Summary of Bering and Chukchi Seas seabird necropsies, 2017-2021. More than 14,000 dead seabirds were reported and a total of 117 carcasses were examined. 92 cases had emaciation identified as the Cause Of Death (COD), seven cases where COD was undetermined, and 17 cases where COD was determined as "Other", which included predation, trauma, encephalitis, peritonitis, and bacterial infection. Low Pathogenic Avian Influenza (n=4) and saxitoxin (n=15) were also detected; however, the virus and biotoxin were not determined to be the COD except for one case in 2020 where saxitoxin toxicosis was suspected.
