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.

Fri 12 Sept 2014 survey

Fri 12 Sept 2014


   Eliese Ronke joined me today for the ongoing Bulls Island waterfowl/shorebird survey. Eliese recently arrived at the USF&WS Cape Romain offices as an SCA (Student Conservation Association?) volunteer intern. She'll be working at Cape Romain NWR through November and hopefully will be joining us again for the survey

   Coastal Expeditions (CEX) once again graciously gave us their best services in getting us out to the islandand back. Many thanks to both Captain Dan and First Mate/Naturalist Olivia Wilson. Their new Carolina Skiff is a really nice ride! CEX has a very busy weekend ahead of themselves with a sunrise beach drop to Bulls Islandtomorrow morning, their usual Saturday Bulls Island ferry runs, and their quarterly Cape Island lighthouse charter from McClellanville to the Cape Romain lighthouse on Sunday. All this will be going on while one of their own gets married Saturday! Congratulations, Gates Roll!

   We tallied 47 target species on today's survey and 59 species overall. Our eBird checklist is appended, below. Avian highlights include: 1 American Bittern, 3 Reddish Egrets, 7 Piping Plovers (none with apparent leg bands or flags), 268 Marbled Godwits (I sure hope that I didn't miss Long-billed Curlews resting in plain sight but with their bills tucked on their backs, but I looked as closely as I could at each.), 2 Pectoral Sandpipers, all three peeps (We actually had 1 Western Sandpiper plus 1 Semipalmated Sandpiper plus 1 Least Sandpiper in one, close, scope view in excellent light.), 1 Great Black-backed Gull, 40 Caspian Terns, 102 Common Terns, 1 Bonaparte's Gull, and 13 Roseate Spoonbills.

   Avian misses (and near-misses) include: Double-crested Cormorant (2), Least Bittern, Glossy Ibis, Mottled Duck, Black-necked Stilt (1), and Least Tern (1).

   Non-avian sightings included: Atlantic bottle-nosed dolphin; American alligator (no surprise there); one small, unidentified snake; and butterflies and dragonflies. The mosquitoes and deer flies were the most numerous I've had this summer, though I still abstained from using repellent on my exposed skin. We missed seeing any fox squirrels. 

   We spoke briefly with two SC DNR law enforcement officers who, along with colleagues flying low and wide over Bulls Bay, were on the lookout for shrimp baiters out before today's noon starting time of the shrimp baiting season. 

   Much to my great and pleasant surprise, the breached dike at Upper Summerhouse Pond (USP) has been repaired! They've removed the damaged trunk and completely filled in the breached site. I understand from CEX's Olivia that they are installing a new trunk further out and around Summerhouse Road (that I didn't actually see today). The residual water in USP is, from two or three weeks of tidal influence, undoubtedly saline and remains very low. I don't know if there is any current salt water influence at the site of the new trunk going in, but likely not much if any. I don't know what their plan (or hope?) for restoring a brackish (or fresh?) water salinity in the impoundment is, but they've really surprised and impressed me with their repair efforts so far, especially with both low funding and so few employees. I was so convinced that USP would be under tidal influence for months, but they showed me otherwise!

   Looking ahead at both the tidal calendar and my own calendar suggests the following dates for our nextsurvey:

Thursday 25 Sept 2014 high tide forecast 5.7 ft at 9:04 AM
Monday 29 Sept 2014 high tide forecast 5.7 ft at 11:39 AM

I'll be leading field trips out to Bulls Island on both Friday and Saturday 26 and 27 Sept 2014 for the Carolina Bird Club's fall meeting in Charleston, so I'll not be able to complete the survey either of those two days. Furthermore, I'm completely disinclined to ask anyone to haul me out there on any Sunday. Though the tide on Thursday will be somewhat earlier in the day than usual for our survey, that seems the most likely date, but stay tuned.

   I'm cross posting this to Carolinabirds for those CBCers coming to Bulls in two weeks. Looking forward to those outings!
