This dataset consists of one table with predator disturbance information from the Common Murre breeding season (June-August) from 2016-2020 on Gull Island, Kachemak Bay, Alaska.
To assess the effects of rotenone (fish toxicant) treatment and possible fish removal effects on nesting Osprey (Pandion haliaetus) populations, nests were observed at two reservoirs east of Ashland, Oregon. Hyatt Reservoir was treated with rotenone on October 12, 1989. Howard Prairie was observed as an untreated reference area. Nests at both reservoirs were observed two years pre-treatment (1988, 1989) and two years post-treatment (1990, 1992). The dataset contains Osprey reproductive parameters, foraging parameters, prey delivery rates and bald eagle piracy rates at eight intensively observed nests. Fish stocking records and creel data were obtained from the Oregon Department of Fish & Wildlife for both reservoirs...

This data release is composed of seven datasets regarding colonial seabirds and forage fish at two seabird nesting colonies on Gull and Chisik Islands in lower Cook Inlet, Alaska. These data were collected to detect changes in the breeding population of Black-legged Kittiwakes and Common Murres on two nesting colonies in lower Cook Inlet and to compare those counts to baseline counts from 1995-1999. They are part of an ongoing study in lower Cook Inlet, Alaska to assess the recent status of forage fish and seabirds (2000-2020).
