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. Photos and captions by staff member Susan Glarum.

"I'm waiting Dear."

"I'm coming, I'm coming"

The Exchange

"I'll see you in about an hour." 

"I always have to rearrange things after you've been here."

School group season has come to an end with only Astoria Elementary School second-graders visiting this week. The highest visitor count for the week was 130 on Sunday morning.
