Fall shorebird migration begins and Gull-billed Terns at every survey site

Fri 8 July 2016

   Jeff Kline joined me for yesterday's waterfowl/shorebird survey. Coastal Expeditions joyfully hauled us out and back; they had a good day with so many passengers showing up that they needed two ferries to get everyone out to the island. Captains Wil Christenson and Gates Roll and First Mate Nick Johnson gave us their usual first class treatment. Wil and Nick knew just where to see the female Red-breasted Merganser hanging out in the marshes of Bulls Bay. 

   We tallied 43 species on the survey proper, 63 species on the island, and 68 species on the day's outing. Our eBird checklist from the island is appended below, FYI.

   There were two recent posts to the Carolinabirds listserv proclaiming the beginning of fall shorebird migration. Steve Shultz reported a Solitary Sandpiper in Dare County, NC, on 24 June and Audrey Whitlock reported Western Sandpipers along Split Pea Inlet, NC, on 26 June. I thought that each was a bit too eager to declare the beginning of fall migration, but after Thursday's survey, I'm in full agreement. We tallied a banded Piping Plover showing full-on alternate (breeding) plumage, several Lesser Yellowlegs, and almost 50 Western Sandpipers. 

   We tallied Gull-billed Terns from each and every survey location on the island. I don't recall any one survey having tallied any species at every survey site before. 

   Other avian sightings of note include Red-breasted Merganser (predictably and reliably hanging out in Bulls Bay along the ferry route), Reddish Egret, Yellow-crowned Night-Heron (Black-crowned Night-Herons are much more common on Bulls), an Osprey juvenile still on the nest, Swallow-tailed Kite, Mississippi Kite (at Garris Landing), Clapper Rail (actually very uncommon on the survey proper), Marbled Godwit, Whimbrel, Black Tern, Common Tern, and Belted Kingfisher (fairly uncommon during summer).

   Non-avian sightings of note included Atlantic bottle-nose dolphin and butterflies. Sarah Dawsey, the refuge manager, reported that she had tallied 65 (I think that was the number) turtle nests on the day and they hadn't even surveyed Bulls Island yet; they headed out to look for turtle crawls on Bulls after we returned to Garris Landing about 4:30 PM. 

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