Summary

These data provide morphological measurements and primary feather length measurements of Black Oystercatcher (Haematopus bachmani) captured at several sites across Alaska and British Columbia between 2019 and 2022. The first table contains mass and morphological measurements of body and bill size. The second table provides lengths of individual primary feathers measured from folded wing photographs using a computer software. These feather lengths are to be used in a size-constrained components analysis to calculate wing shape such as pointedness and convexity.

Purpose

These data were collected as part of a broader project studying Black Oystercatcher morphology, movement, and diet across Alaska, USA and British Columbia, Canada. Photographs of wings were taken in the field of folded wings on a board with a ruler for scale. The primary length measurements were collected using computer software analysis from wing photos.
