Data on puffin chick-meals were collected to characterize forage communities and determine meal energy density. This dataset contains chick diet data and consist of: date, location, species, mass, total length, fork length and comments. Seabirds are strongly shaped by the energetic constraints they face in supplying food to their chicks at centralized colonies while foraging for patchily distributed prey in surrounding waters. Using puffin diets as indicators of forage fish communities, we assessed spatial variation in forage fish community structure, and compared chick meals between colonies and ecoregions to determine how they differed with prey number, biomass, energy density, and species richness. 20120803 20140816 observed Complete None planned Our study area spanned 2,400 km from Kodiak Island in the northern Gulf of Alaska westward along the Alaska Peninsula to the terminus of the Aleutian Archipelago. -180.0000 -138.5156 66.9301 48.6910 USGS Metadata Identifier USGS:ASC331 ISO 19115 Topic Category Biota Oceans Environment NASA GCMD Earth Science Keyword Thesaurus Birds Marine ecosystems USGS Biocomplexity Thesaurus Aquatic birds USGS Thesaurus Ecology None Chick diet Burrow Forage fish Fish Prey Energy density USGS Geographic Names Information System (GNIS) Alaska Gulf of Alaska Aleutian Islands Alaska Peninsula North Pacific Bering Sea None Tufted Puffin Invertebrates ITIS Integrated Taxonomic Information System Unknown online database online ITIS-North America Details of taxonomic rank above the class aves retrieved November 5, 2024, from the ITIS online database https://www.itis.gov https://www.itis.gov Taxonomic rank follow the most current (as of November 2024) taxonomic designation by the ITIS.

The USFWS Alaska Maritime National Wildlife Refuge (AMNWR) and the Aleutian and Bering Sea Islands LCC also provided financial and logistic support. We are grateful to AMNWR managers Steve Delehanty, Jeff Williams, and Heather Renner for program support and for the use of data from Aiktak and Buldir, and to Captain William Pepper and crew of the R/V Tig ̂lax ̂ for outstanding research logistic support in the Aleutians. Additional advice and support was provided by Vernon Byrd, Scott Hatch, Lisa Spitler, and Bill Sydeman.

Data is observational, there will be missing data, and some fields are not relevant or obtainable during collection. Latitude and longitude coordinates were obtained from a commercially available Garmin GPS with a resolution to within ± 4 m. FIELD: To obtain chick meals we placed wire-mesh screens over the entrance of puffin burrows so that adults returning with food for chicks could not enter their burrows, and subsequently dropped chick-meals at burrow entrances. Screens were placed at burrow-entrances and left in place for 2-4 hours. All screens were retrieved and chick meals delivered by adults were collected. Chick meals were brought back to the ship’s lab where prey samples were measured and identified to the lowest possible taxon. Prey items were measured individually (total length, mm) and total meals were weighed to the nearest 0.1 g. For common species, we measured mass of a subsample from each colony, and estimated mass from length for remaining fish using linear regression. Unknown Chick meals were collected from Tufted Puffin colonies in the Aleutian Islands and along the Alaska Peninsula.
