Where do winter crows go? Characterizing partial migration of American Crows with satellite telemetry, stable isotopes, and molecular markers

http://www.americanornithologypubs.org/doi/full/10.1642/AUK-18-23.1


All recorded movements of (A) 3 satellite-tagged resident American Crows in Davis, California, and (B) 1 resident in Utica, New York, USA, over the duration of the study. Colors indicate different individuals. Data were recorded for each bird over a 12?42 mo period.


First recorded fall migratory movements of 8 satellite-tagged American Crows on the west coast and 5 on the east coast of North America. Colors indicate different individuals.

Effects of climate change and environmental variability on the carrying capacity of Alaskan seabird populations

http://www.americanornithologypubs.org/doi/full/10.1642/AUK-18-37.1


Sites of monitored seabird colonies in Alaska, USA (yellow triangles), and their corresponding ecoregions. St. Lazaria Island is within the Gulf of Alaska, even though it is shown outside the scope of this large marine ecosystem (as delineated by https://www.st.nmfs.noaa.gov/ecosystems/lme/index; M. A. Smith personal communication). White polygons represent the spatial extent of extracted covariates: sea surface temperature (rectangles) and euphausiids (circles).

Evaluating time-removal models for estimating availability of boreal birds during point count surveys: Sample size requirements and model complexity

http://www.americanornithologypubs.org/doi/full/10.1650/CONDOR-18-32.1


Locations of point count surveys from 1991 to 2014 compiled across boreal and hemiboreal regions (according to Brandt 2009) of North America by the Boreal Avian Modelling Project (BAM). We analyzed the point counts for which surveyors recorded when each bird was first detected relative to multiple time intervals (colored dots). Gray dots represent point counts with a single time interval. Numbers of point count surveys (n) in each of 11 different combinations of the count duration (min) and the number and length of the time intervals are given in the legend. The inset shows an expanded view of a region in northeastern Alberta, Canada, where many projects with different counting methodologies overlapped.
