Wed 16 July 2014
All,
Rob Dillon joined me yesterday for the ongoing Bulls Island waterfowl/shorebird survey. We caught the 9:00 AM Coastal Expeditions ferry out and the 4:00 PM ferry back. Captain Gates Roll and First Mate/Naturalist Olivia Wilson treated us very well giving us their usual excellent service on our day's effort. Thanks, CEX! Even though we were scheduled on the ferry, USF&WS maintenance worker Greg Geathers saw us unloading in the Garris Landing parking lot and came over to make sure that we had a boat ride out to the island; thanks, Greg.
Even though it's what I would call "high summer," it was the 15th of July after all, our survey turned up pretty fair results. We tallied 39 species on the survey proper, 55 species overall on the whole day's outing; my eBird report on the day is appended, below, FYI. Birds of the day were a pair of American Avocets seen in Jack's Creek. Both gulls-and-terns and shorebirds were represented in surprisingly high numbers. We tallied many Royal Terns, Sandwich Terns, Black Terns, Forester's Terns, Gull-billed Terns, Least Terns, and a pair of Herring Gulls. Shorebirds in good number included Black-bellied Plover (listed from eBird below as Grey Plover), Short-billed Dowitcher, Marbled Godwit, Spotted Sandpipers, and Semipalmated Sandpipers.
I tallied the first-of-year Roseate Spoonbills for the survey in Upper Summerhouse Pond; these 3 happened to be exceptionally pink and pretty, the pinkest I've ever seen. We also saw 2 Mallards, 3 Swallow-tailed Kites, fewer Mottled Ducks and Common Gallinules than recent surveys, and surprisingly low numbers of both Red-winged Blackbirds and Boat-tailed Grackles, and only 1 Double-crested Cormorant.
Other non-avian sightings on the day included American alligators (no surprise there), Atlantic bottle-nosed dolphin, fox squirrels (1 along Summerhouse Road at Beach Road plus 1 in the oak lawn in front of the Dominick House), and several spiders, butterflies, and dragonflies. Mercifully all-but-absent again were biting insects; the steady SSW winds really helped keep them down. As he had done back in April, Rob looked for freshwater gastropods; after beating back the lounging alligators, he waded into several impoundments to find only limpets (Ferrissia fragile); absent were the Physa caolinae pulmonates that he had found back in April. He suspected that there might be some seasonality to the snails, and he's looking forward to a fall and winter sampling on Bulls to further explore that hypothesis.
Tall clouds started darkening the western horizon about 1:45 PM, and we understood from Gates and Olivia that weather was building and threatening to move over us. We pushed just a little bit to finish up early to try an beat the weather. As it turned out, the threat passed without incident and left us at Garris Landing back in the sunshine.
We started our day hearing Painted Buntings (and saw a female) at Garris Landing and heard PABU a couple of times on the island, but hadn't seen a breeding plumage male. While walking back down the dock at Garris Landing talking about what a good day's outing it had been, I mentioned that I'd try to find a male PABU in the parking lot for Rob to see well. He accepted my offer, actually insisted that one be waiting for us in the oak tree right above my parked car. I did find him a beautiful male PABU, but we had to walk about 20 yards to the gravel driveway back to the maintenance shed to track one down. Rob graciously accepted that binocular view of a breeding plumage male PABU.
Looking ahead at the tidal forecast suggests the following dates for our next survey:
Tues 29 July 2014 high tide 4.7 ft at 10:05 AM
Wed 30 July 2014 high tide 4.7 ft at 10:42 AM
Thurs 31 July 2014 high tide 4.7 ft at 11:19 AM
Stay tuned for further plans.
Regards,
David
