Fri 26 Sept 2014 survey

Fri 26 Sept 2014


   Yesterday Wil Christenson, formerly the Captain of the Coastal Expeditions (CEX) ferry, and Olivia Wilson, the current First Mate of the CEX ferry, joined me for the Bulls Island waterfowl/shorebird survey. CEX owner Chris Crolley was at Garris Landing to give us a good send off with his long-ago Captain Al back at the helm (apologies, but I can't recall Al's last name) and Naturalist/Guide Gates Roll back from his recent wedding. CEX gave us their usual top-notch service in getting us out to Bulls and back.

   We tallied 35 target species on the survey proper, 58 species overall; our eBird checklist on the whole day's outing is appended, below, FYI. Shorebird migration seems to be past peak and several of the usual summer resident birds appear to have left. Avian highlights include good numbers of Pied-billed Grebes, 6 Reddish Egrets, many Common Gallinules, American Coot, Sora, Common Tern, Roseate Spoonbill, American White Pelican, Bald Eagle, Peregrine Falcon (one resting on the North Beach--strange how there were almost no small shorebirds within sight there  ;-)) , Merlin (it was a terrific day for raptors!), Seaside Sparrow, and Bobolink. 

   Summer avian residents apparently now gone include Wilson's Plover, Black-necked Stilt, Least Tern, Gull-billed Tern, and Black Tern.

   Non-avian sightings included at least 25 American alligators at the trunk connecting Jack's Creek and BullsBay, Atlantic bottle-nosed dolphin, love bugs, and mosquitos. 

   The recent breach at the SW corner of Upper Summerhouse Pond (USP) has been repaired and a new drain (not a trunk but a metal drain pipe, ostensibly functioning as an overflow outlet from USP to the salt marsh) has been placed in the extreme SE corner of USP. The water level has risen a bit in USP due to, I suspect, recent rains. An impressive and quick repair given the tight budgets that the refuge has been working under!

   I lead a Carolina Bird Club field trip out to Bulls Island today on a CEX charter. With 16 great birders in total and an exceptional CEX guide in Chris Crolley, we tallied 85 species on the day! I'm taking another CBC field trip out to Bulls tomorrow where we'll try for an even larger tally, so here's hoping that Chris dreams about sparrows again tonight.

   Looking forward at the tide calendar and my own calendar suggests the following possible dates for our nextsurvey:

Monday 13 Oct 2014 high tide of 5.8 ft at 12:07 PM
Tuesday 14 Oct 2014 high tide of 5.5 ft at 12:59 PM

High tides on these dates are slightly later than we typically access, but I have other plans for the preceding several days that will prevent me from going until Monday or Tuesday. Stay tuned for final plans.
