4 Aug 2015 Survey. Shorebird migration is well underway, and the bird of the day was...three

Tues 4 Aug 2015

   The shorebird migration was under way on Bulls Island today during our regular waterfowl/shorebird survey. Irvin PItts, who drove down from Lexington early this AM, and Nolan Schillerstrom joined me today and contributed greatly to this ongoing volunteer surrey effort. Irvin was rewarded with two (I believe) year birds for his list and Nolan added two life list species to his. Many thanks to both of them for being so generous with their time, effort, and expertise.

   Coastal Expeditions, specifically Captain Richard Stuhr and First Mate Nick Johnson, graciously provided our boating transportation out to Bulls and back. I was pleasantly surprised to see that they had about 30 customers show up on a Tuesday morning in early August just after overnight showers had barely left the area. Fortunately the weather was terrific for us; skies were bright overcast (shading us from a strong August sun) with just a little direct sun breaking through after lunch, but the wind was a gentle land breeze that allowed the mosquitoes and deer flies to really swarm. Rainfall over the previous 2 days totaled approximately 1.5 inches leaving most of the island damp.

   We tallied 22 shorebird species today and 0, yes…zero, waterfowl. We had 51 target species on the survey proper, 66 species on the island, and 70 species for the ferry ride and the island combined. Adding Irvin's checklist for Garris Landing brings our total for the day up to 78. Not too bad for early August. This may have been the first time that we've not recorded even one duck on the survey, but that was OK because the diversity of shorebirds completely distracted us from that fact. 

   The "bird of the day" was a Pectoral Sandpiper on the edge of Jack's that posed for Irvin's camera; after walking out into Jack's Creek we very quickly tallied 7 additional Pectoral Sandpipers! I was really enjoying seeing so many "birds of the day" until we nearly immediately tallied a new "bird of the day," 3 Stilt Sandpipers. But that was again almost immediately replaced by yet another "bird of the day," a first record for the survey (I think) and a first eBird record for Bulls Island: Wilson's Phalarope! Actually 2 WIPH swimming in the shallow water together! I guess this was a "three birds of the day" kind of day.

   Other notable shorebird species tallied today included Piping Plover, Whimbrel, Marbled Godwit, Red Knot, and all three peep sandpipers (Western, Semipalmated, and Least). It was a good day for shorebird species on the island. Other notable target species included Great Back-backed Gull and Roseate Spoonbill (the first I've seen on Bulls since February). The "trash bird" of the day must have been Black Tern (76) as we seemed to see them everywhere either resting on the sand or soaring on wing. 

   Interesting non-target species included Red-shouldered Hawk, Mississippi Kite, Swallow-tailed Kite, and Yellow Warbler. Our eBird checklist from the island is appended below.

   Avian misses included Mottled Duck, Black-bellied Whistling Duck (strange how a species that had never been recorded on Bulls prior to May 2014 has now become a "missed" species), Purple Gallinule (very recently reported to CEX's Nick who reported it to me), and Reddish Egret. 

   Non-avian sightings included Atlantic bottlenose dolphin (including one that fully breached in the ocean immediately beyond the breakers!) and numerous butterflies and dragonflies. We missed seeing fox squirrels.

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

Mon 17 Aug 2015 5.0 ft high tide forecast at 10:17 AM
Tues 18 Aug 2015 5.0 ft high tide forecast at 10:55 AM
Wed 19 Aug 2015 4.9 ft high tide forecast at 11:34 AM
Th 20 Aug 2015 4.9 ft high tide forecast at12:14 PM

Looking forward to continued fall migration!
