Hi all!

We wrapped up the season last Thursday with boat-based surveys of Snake Island and the Outer Harbor.  We observed 7 adult American Oystercatchers with 4 chicks on Snake, as well as one adult on Fisherman’s Bend in Winthrop and one adult on the shore of the Logan runway.  Susannah reported 5 fledged chicks on Snake earlier in June.  Of the four we saw last Thursday, 3 were two young to have been observed in June, indicating that Snake has potentially produced at least 8 fledged chicks this season!

Unfortunately, observations of oystercatcher productivity elsewhere in the Harbor have been less fruitful… We observed 2 adults on Calf, 1 adult on Little Calf, 1 adult on The Graves, and 1 adult on Shag Rocks, all feeding intertidally.  No other fledged chicks were observed.  A summary of oystercatcher observations throughout the 2012 season and our ‘best guesses’ for productivity outcomes are attached.

Other items of note on Thursday were a Whimbrel on Green Island, and 6 harbor seals hauled out on The Graves.  We also noted feeding Spotted Sandpipers on Snake, Calf, Little Calf, Green, Middle Brewster, and Outer Brewster.

Thanks you all for a wonderful season!
