Sat 30 Aug 2014 survey


Sat 30 Aug 2014

All,

   Bob Seigler joined me yesterday for the ongoing Bulls Island waterfowl/shorebird survey. I was pleased to see Coastal Expeditions' owner and captain Chris Crolley for our ride out to Bulls on their brand new Carolina Skiff. Certified by the Coast Guard for 20 passengers, this new boat has twin 115 hp motors and is stable and fast; it will serve CEX for smaller charters, beach drops, and smaller regular ferry service like we had yesterday morning. CEX's Captain Gates Roll ferried us off the island. Many thanks to both Chris and Gates. Nice new ride! 

   Bob and I tallied 47 target species for the survey proper, 61 species overall on the whole day's outing. Our eBird checklist for the day is appended, below, FYI. Species of note include Black-bellied Whistling Duck, Blue-winged Teal, Reddish Egret, Roseate Spoonbill, Cooper's Hawk, Piping Plover (no apparent leg bands or flags), Red Knot (no apparent leg bands or flags), Western Sandpiper, Bonaparte's Gull (very unexpected), Caspian Tern, and Common Tern. Avian misses include Least Bittern, Gull-billed Tern, and Red-winged Blackbird (I probably looked right through and/or over them). We also tallied very few woodland species, even considering that we were driving rather than walking the roads. 

   Non-avian sightings included multiple sightings of bottle-nosed dolphins (including an up-close view of some "impact feeding" behavior where the dolphin uses its tail to slap the shallow water and, thus, their prey fish), American alligators keeping cool in the water, butterflies, and dragonflies. We missed seeing any fox squirrels. 

   There's been a VERY BIG change to Upper Summerhouse Pond (USP) since my last visit there on Thursday 14 Aug 2014. The dike separating USP from the extensive salt marsh along the extreme SW corner of the impoundment has been breached. The trunk (water control structure) is completely exposed and the earthen dike is completely washed away around both sides and top of the trunk leaving a 15 m break in the dike. Upper Summerhouse Pond is now completely tidal! We saw it at about an hour and a half before the afternoon low tide and the water was fast draining out leaving extensively exposed mudflats and vegetation in USP.

   This same USP dike was breached during Hurricane Hugo (21 Sept 1989), though I believe that this new breach around the trunk is 40 m or so from the Hugo breach site. I've studied some of my photos from Dec 1989 but am unable to confirm the precise location of that breach. I suspect that the USF&WS will bring in a private contractor to make repairs, but with their very tight budget such a fix may not come soon. In the meantime it will be interesting to follow the birds using USP. Yesterday USP had an American White Pelican, 15 Roseate Spoonbills (PINK!), both species of yellowlegs, the only Black-necked Stilts for the day, and the typical egret, heron, cormorant, and ibis species. 

   I am cross-posting this email to Carolinabirds for the upcoming (26 and 27 Sept 2014) Carolina Bird Club meeting in Charleston and the trips then to Bulls Island.

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

Thurs 11 Sept 2014 high tide forecast 6.4 ft at 10:05 AM
Fri 12 Sept 2014 high tide forecast 6.2 ft at 10:57 AM
Sat 13 Sept 2014 high tide forecast 6.0 ft at 11:50 AM

Stay tuned for further plans.

Th 13 Aug 2014 survey


Th 14 Aug 2014

All,

   Susan Thompson and Brian Houghton joined me today on Bulls Island for the ongoing waterfowl/shorebirdsurvey. It was a "Chamber of Commerce" weather day! Captain Richard Stuhr and First Mate/Naturalist Olivia Wilson of Coastal Expeditions gave us their usual first rate service in getting us out to the island and back. Many thanks!

   We tallied 46 species on the survey proper, 61 species on the day's outing. My eBird checklist is appended, below, FYI. Great finds on the day included Purple Gallinule (including 1 mature and 3 chicks!), Black-bellied Whistling Ducks, Green-winged Teal, Reddish Egret (juvenile), Roseate Spoonbill, Cooper's Hawk, Bald Eagle, Piping Plover, Whimbrel, and American Avocet. Misses included Wilson's Plover, Marbled Godwit (recently present in high numbers), and American Oystercatcher (though Richard and Olivia saw one early that I missed).

   Non avian wildlife sightings included Atlantic bottle-nosed dolphin, fox squirrel (1 along the road to the dock, 1 along Lighthouse Road at Beach Road), American alligator, spiders on webs, butterflies, and dragonflies. Once again the mosquitos and deer flies were mercifully very few. 

   After Sunday's perigee/full moon (aka "super moon") the tides were running high and were further aided by steady NE to E winds today. The trunk connecting Jack's Creek to Bulls Bay was open allowing a significant inflow of seawater into Jack's Creek thus raising the water level appreciably. Also the marsh oceanfront at Jack's Creek has recently been filled with the high tides yet continues to drain back into the ocean. The dunes continue to accrete on the North Beach--there was significant exposed beach even with these astronomical high tides. 

   Looking forward at the tidal calendar suggests the following dates for our next waterfowl/shorebird survey:

Th 28 Aug 2014 high tide 5.2 ft at 10:09 AM
Fri 29 Aug 2014 high tide 5.2 ft at 10:44 AM
Sat 30 Aug 2014 high tide 5.2 ft at 11:21 AM

Stay tuned for further plans.

   I am cross-posting this email to Carolinabirds in advance of the upcoming fall Carolina Bird Club (CBC) meeting in Charleston 26 to 28 Sept 2014 and the field trips to Bulls Island.

Fri 1 Aug 2014 survey


Fri 1 Aug 2014

All,

   Susan Hancock joined me yesterday for the Bulls Island waterfowl/shorebird survey. We were fortunate to have three great hosts from the Coastal Expeditions (CEX) ferry carry us to and from the island: Owner and Captain Chris Crolley and First Mates and Naturalists Olivia Wilson and Nick. (Sorry, I can't recall Nick's last name.) CEX has been such a great asset for this survey, always giving us first rate service, that I wish I could do more than simply say "Thank you!"

   The morning's high tide was forecast to be only moderately high at 4.7 ft, but the stiff East winds kept the levels much higher through the whole day. We had only a trace of rain at 3:30 PM right at the end of the survey, but the ferry ride back was in and out of light rain that dampened our clothing but failed to dampen our spirits after such a great day's birding.

   We tallied 45 target species on the survey proper, 59 species on the day's outing. My eBird checklist is appended, below, FYI. Avian species of note include: 1 Piping Plover (no leg bands), Roseate Spoonbills (fully PINK!), American Avocets, Reddish Egret, and 1 Red Knot. We also had good numbers of Short-billed Dowitchers, Marbled Godwits, Semipalmated Sandpipers, Least Terns, Sandwich Terns, and Black Terns.

   Non-target avian species seen included 1 Belted Kingfisher and 1 Northern Rough-winged Swallow. Misses included Least Bittern and Wilson's Plover. Non-avian sightings included Atlantic bottle-nosed dolphin, white-tailed deer, cottonmouth, butterflies, and dragonflies. Also missed were fox squirrels. The mosquitoes and deer flies were very few. (The steady East wind kept the insect pests down and kept the tide up much higher than the 4.7 ft predicted high tide.)

   The North Beach continues to accrete! The dune line is taller, and the vegetation, especially the sea oats, is growing much further out and in much greater number than even two weeks ago. Strangely, however, the North Beach continues to have few birds, a trend that has been fairly consistent over this entire calendar year. The water level in the marsh oceanfront at Jack's Creek appears relatively stable though low, but the recent breech in the dune line remains. It will be interesting to see what happens there with the upcoming perigee full moon, aka super moon at 2:09 PM Sun 10 Aug 2014, and the associated high tides. I hope that the winds will be favorable to protect the whole island during those several days of spring astronomical tides.

   Looking forward at the tidal calendar suggests the following dates to consider for our next survey:

Tues 12 Aug 2014 high tide 5.9 ft at 9:33 AM
Wed 13 Aug 2014 high tide 6.0 ft at 10:29 AM
Thurs 14 Aug 2014 high tide 5.9 ft at 11:24 AM
Fri 15 Aug 2014 high tide 5.8 ft at 12:20 PM

   Stay tuned for further plans.

Regards,

David
