Fri 16 May 2014 survey

Sun 18 May 2014


   This Friday past (16 May 2014) Kathy Greider and Grant Greider joined me on Bulls Island for the ongoingwaterfowl/shorebird survey. We caught the 9:00 AM CEX ferry out; Captain Richard Stuhr and First Mate/Naturalist Olivia graciously hauled us out to the island and back through an exceptionally low tide. I saw exposed mudflats where I knew them to be but had never before seen them. Captain Richard passed that "trial by fire" (maybe better "trial by low water") with aplomb. CEX had a busy day beyond the scheduled regular ferry service with a chartered school group and their monthly weekend overnight customers. 

   We were able to share scope views of our last two birds on the day (simultaneously some of our best birds of the day) on Upper Summerhouse Pond with the overnighters: Ruddy Ducks (2 males in breeding plumage plus 1 female--I now know why they're AKA blue bills) and a Greater Scaup (female). Other notable sightings included an American Black Duck (distinctly violet speculum lacking any white borders and overall very dark), FOS Black Terns, many hundreds of Royal Terns and Black Skimmers, Black Scoters, Red-breasted Mergansers, many Anhingas, Red Knot, and all three peep sandpipers.

   Both Jack's Creek and Upper Summerhouse Pond are maintaining high water levels and, therefore, few shorebirds. The newly opened inlet at the oceanfront marsh at Jack's Creek remains and is keeping that water low, however the shorebirds there were not as numerous as usual.

   Non avian sightings on the day included bottle-nosed dolphin, fox squirrel (1 along Summerhouse Pond Road), many dragonflies, and the usual bevy of American alligators. Recently reported avian species that we did not see included Roseate Spoonbill and Reddish Egret (we'll look again next survey). We also missed seeing Bald Eagle. :-(  My eBird checklist on the day's outing is appended, below, FYI.

   Looking ahead at the tide calendar suggests the following dates for our next survey:

Friday 30 May 2014 high tide 4.7 ft at 9:38 AM
Saturday 31 May 2014 high tide 4.5 ft at 10:20 AM
Monday 2 June 2014 high tide 4.3 ft at 11:47 AM
Tuesday 3 June 2014 high tide 4.3 ft at 12:33 PM

   Stay tuned for further plans.
