Th 6 Feb 2014 survey

Th 6 Feb 2014
   On Tuesday 4 Feb 2014 Dan Ashford motored me out then joined me for the waterfowl/shorebird survey onBulls Island. My eBird report is appended below. It was cold and breezy Tuesday--wished I'd worn warmer clothes, but since I was out birding it was all good. About two weeks ago one riser board in the trunk connecting Jack's to the bay and another riser board in the trunk connecting Upper Summerhouse Pond to the marsh were removed; both impoundments are still draining and the water level in each has dropped very slightly but noticeably. Salinity measurements show Jack's about on target (14.0 ppt), Upper Summerhouse Pond a bit higher than desired (11.9 ppt), and all other impoundments being essentially fresh water (<= 1 ppt) [accepting Moccasin Pond that continues to receive salt water intrusions on astronomically high spring tides, according to Dan].
   Highlight bird of the day must go to the four Canvasback in Jack's Creek. I'd seen Canvasback there on Monday 13 Jan 2014 while conducting the USF&WS midwinter waterfowl survey, and that was the first time in many years that I'd seen any Canvasback at all on Bulls (so long ago that I can't remember when that was--maybe decades.) Now we've gotten them officially on our waterfowl/shorebird survey! [Were they seen on thesurvey prior to my joining in Dec 2011? I've not looked at the data.] Hope they hang around for the rest of the winter.
   Waterfowl on Bulls continue in relatively good numbers this winter, the best showing that I've seen in many years. Hopefully the actual numbers (when I get some time to look at them) will support this impression. There were good counts of Northern Shoveler (57) Northern Pintails (23) , Redheads (240), Lesser Scaup (766), Buffleheads (136), and Ruddy Ducks (437). Other species of note include a good flock of Black-crowned Night-Herons (44), Piping Plover (2), Killdeer (43--they seem to be everywhere I look since our recent frozen precipitation event), Wilson's Snipe (11) and Forester's Terns (141). We tallied 78 species in total for the day's outing including 51 target species.
   Interestingly the north beach continues to disappoint this winter. The only shorebirds present during Tuesday's survey were Ruddy Turnstone (2) and Sanderling (6); otherwise there were only a few flyby Double-crested Cormorant (12), Lesser Scaup (12), a single Black Scoter (plus a recently deceased and Black Scoter), and a small contingent of gulls and terns (11 individuals, total). The beaches at Price's Inlet were also nearly completely void of birds. (I surveyed that SW end of the island specifically for the statewide shorebird surveythat just concluded.)
   I did spend a few minutes looking for the recently reported White-crowned Pigeon and Scissor-tailed Flycatcher but without success. Mammals seen included Fox Squirrel (3), White-tailed Deer (3), and Raccoon (1). Oh...and there may be canines on the island; tracks resembling canine tracks have been seen and are being scrutinized as possibly from coyote or fox. No sightings of actual canines yet. [The Red Wolves currently at the See Wee Visitors' Center don't count, and the Red Wolf breeding program hasn't operated on Bulls for several years.]
   The high tide on Thursday 20 Feb 2014 will be 4.6 ft at 10:44 AM. That will be our target date for the nextsurvey, so stay tuned for a confirmatory email with those plans.
