I captured this Black Oystercatcher pair in profile as they scrambled around some rocks. They paused for just a second, in a perfect, pointed posture, one against the other.

The bird in back has an eye fleck, which usually means female. From the Journal of Field Ornithology:

“ … we found that eye flecks were sex-linked. Using an eye-fleck model where all females have full eye flecks and males have either slight eye flecks or no eye flecks, we correctly assigned the sex of 117 of 125 (94%) oystercatchers.”

The photos below were taken on the same day, on the same rock as the two split and converged, one always looking for the other.
