Tues 11 Nov 2014 survey

Tues 11 Nov 2014


   Wil Christenson, Eliese Ronke, and Olivia Wilson joined me today for the Bulls Island waterfowl/shorebird survey. Coastal Expeditions'  (CEX) Captain Richard Stuhr and First Mate Olivia Wilson graciously got us out to the island and back. CEX's Captain Chris Crolley gave us a sendoff and a great heads-up on where to look for the returning waterfowl. As always I am very grateful for CEX's expertise, interest, and service.

   We had a sneaky good tally of 44 target species on the survey proper and 82 species on the whole day's outing. Our eBird checklist for the day is appended, below, FYI. Waterfowl have begun returning to Bulls Island and winteringshorebird species are increasing.  (Maybe they've sensed that major cold front barreling down from Canada and moved ahead of that weather. Who knows?) 

   We all had excellent scope views of an American Bittern that flushed across a narrow ditch and perched high in the grasses of Jack's Creek. The most unexpected sighting was a White-winged Scoter in Upper Summerhouse Pond. Other sightings of note included either first-of-season (FOS) or first high counts of wintering species including: Little Blue Heron, Yellow-crowned Night Heron, Bufflehead, American Black Duck, Green-winged Teal, Ruddy Duck, Dunlin, Northern Shoveler, Bonaparte's Gull, Horned Grebe, Redhead, Lesser Scaup, Red-breasted Merganser, and Common Loon.

   Upper Summerhouse Pond (USP) continues to impress with a wide variety of shorebirds, wading birds, waterfowl, and passerines. There is an ongoing algal bloom in parts of USP leaving me wondering whether is is a salt water (likely) or fresh water (much less likely) bloom. I really need to get a refractometer so that I can read salinities in the impoundments. There was a large mixed flock of shorebirds in the oceanfront marsh at Jack's Creek that was flushed by a Peregrine Falcon before we got a scope on them; after that flush, the marsh was all but empty of shorebirds and was as quiet (bird wise) as I ever remember. 

   Non avian sightings included long-tailed skippers, Monarch butterflies, Gulf fritillaries, yellow sulfur butterflies, carpenter bees, a fox squirrel, baby American alligators (count of 23), many adult gators (Wil had to literally kick one gator's tail out of the way so that the truck could just squeeze by), a pair of shrews (likely--heard only), and a relatively fresh marine mammal stranding on the North Beach--an Atlantic bottlenose dolphin. 

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

Tues 25 Nov high tide 6.1 ft at 9:24 AM
Wed 26 Nov high tide 5.9 ft at 10:15 AM
Fri 28 Nov high tide 5.6 ft at 12:10 PM

Stay tuned for final plans.
