Boyd's shearwater

The epithet commemorates British ornithologist Arnold Boyd.

Females take longer foraging trips and travel further north.

This seems to be driven by differing preferences for chlorophyll concentration and sea surface temperature.

This may be because females spend more time incubating eggs and are therefore more deprived of nutrition.

It has also been shown to be synonymous with the extinct Puffinus parvus Shufeldt of Bermuda.
