Data to accompany the article 'Nesting Success of the Commodore Park Great Blue Heron Colony, 2014-2023', published in Northwest Science

A Pacific Great Blue Heron (Ardea herodias fannini) colony in Seattle, Washington, was studied from 2014 to 2023. Community scientists observed the usage of 120 nest locations repeatedly throughout each nesting season, for a total of 672 nest-years. This data package includes the dates of key phenological stages for each nest-year as well as the number of chicks present. It also includes the script used to analyze these data and create the figures within the Marsh et al. manuscript published in Northwest Science.
