Black Oystercatcher Morphology and Primary Feather Lengths in Alaska and British Columbia, 2019-2022 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.
