Black Oystercatcher Morphology and Primary Feather Lengths in Alaska and British Columbia, 2019-2022
May 13, 2024
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.

Latitudinal gradients and sex differences in morphology of the Black Oystercatcher (Haematopus bachmani)
Environment and behavior are widely understood to affect bird morphology, which can lead to differences among subspecies or populations within a wide-ranging species. Several patterns of latitudinal gradients in morphology have been described, though Allen's and Bergmann's rules are the most well-known and have been tested and confirmed across a diversity of taxa and species. These state that indi
