Notes from the Week
The Black Oystercatchers took center stage this week. Susan Glarum captured a fabulous series of photos of our favorite oystercatcher couple sharing parental duties at Haystack Rock. This nesting pair in the saddle gives us a great opportunity to observe the lengths to which birds go to successfully hatch their eggs. One adult is almost always on the nest to keep the eggs protected from the elements and predators. The exchange between parents is quick so as to expose the eggs for only a short time. The couple was spotted chasing away another Black Oystercatcher early in the week. Later in the week, two gulls harassed the incoming Oystercatcher who did not go immediately to the nest.
