Fri 30 May 2014 survey


Fr 30 May 2014

All,

   I had a great day on Bulls Island today conducting the waterfowl/shorebird survey. Captain Richard and First Mate Olivia of CEX's Bulls Island Ferry were gracious and helpful to haul me out there, set me up with a truck, and then to haul me all the way back at the end of the day. There was only 0.02 in of rain that fell from about 1 PM till about 2:30 PM--it was just barely enough to force me to put on a rain jacket, mostly because it was threatening to become steadier. Clouds and fairly moderate temperatures kept the day's weather otherwise very tolerable.

   I tallied 42 target species on the survey proper and 61 species overall (full eBird checklist is appended, below), though counts of total individuals was down somewhat (727 individuals) compared to most outings. In short, pretty good variety but overall numbers somewhat lower than recent. 

   I had advance word of both Reddish Egret (got it on the North Beach) and Purple Gallinule (missed it in its reported location in Lower Summerhouse Pond along Beach Road). I'll keep looking for the PUGA. (Interestingly a PUGA has also been recently reported from Caw Caw; perhaps there's a minor PUGA irruption ongoing.)

   Species of the day has to be a new one for the survey and perhaps a new species for the island: Black-bellied Whistling-Duck! I had 27 calmly sitting in the small impoundment wedged between the Boneyard, Moccasin Pond, and Jack's Creek (I can't recall the name of this impoundment--help me, Dan? It shares a trunk with Jack's where you take the "second" water quality data for Jack's.). Just outside of the survey area! Not to worry, as it happens, as I later had 5 more BBWD on the wing flying out of the Upper Summerhouse Pond! BBWD officially on the survey!

   Other notable avian sightings included: Red-breasted Merganser (in the saltwater marshes between landings), juvenile Common Gallinules, American Coot, Black Tern, Sandwich Tern, and Black Scoter. Shorebird numbers were overall down (1 Dunlin and no yellowlegs, Black-bellied Plover, or Red Knot, e.g.), though I had almost 70 peeps some of which I could ID as Western Sandpiper, some of which I couldn't distinguish Western Sandpiper versus Semipalmated Sandpiper. That's often a tough ID to make--I'm working hard on the peeps.

   Non avian sightings included fox squirrels (1 in the yard/picnic grounds plus 1 along Beach Road in the AM plus 2 in the yard about 3:30 PM), white-tailed deer, bottle-nosed dolphin, and several alligators.

   Looking forward at the tide chart suggests the following dates to consider for the next survey:

Sat 14 July 2014 high tide 5.1 ft at 9:12 AM
Mon 16 July 2014 high tide 5.2 ft at 11:04 AM
Tues 17 July 2014 high tide 5.2 ft at 12:03 PM

Stay tuned for further plans.

Regards,

David

Fri 16 May 2014 survey


Sun 18 May 2014

All,

   This Friday past (16 May 2014) Kathy Greider and Grant Greider joined me on Bulls Island for the ongoingwaterfowl/shorebird survey. We caught the 9:00 AM CEX ferry out; Captain Richard Stuhr and First Mate/Naturalist Olivia graciously hauled us out to the island and back through an exceptionally low tide. I saw exposed mudflats where I knew them to be but had never before seen them. Captain Richard passed that "trial by fire" (maybe better "trial by low water") with aplomb. CEX had a busy day beyond the scheduled regular ferry service with a chartered school group and their monthly weekend overnight customers. 

   We were able to share scope views of our last two birds on the day (simultaneously some of our best birds of the day) on Upper Summerhouse Pond with the overnighters: Ruddy Ducks (2 males in breeding plumage plus 1 female--I now know why they're AKA blue bills) and a Greater Scaup (female). Other notable sightings included an American Black Duck (distinctly violet speculum lacking any white borders and overall very dark), FOS Black Terns, many hundreds of Royal Terns and Black Skimmers, Black Scoters, Red-breasted Mergansers, many Anhingas, Red Knot, and all three peep sandpipers.

   Both Jack's Creek and Upper Summerhouse Pond are maintaining high water levels and, therefore, few shorebirds. The newly opened inlet at the oceanfront marsh at Jack's Creek remains and is keeping that water low, however the shorebirds there were not as numerous as usual.

   Non avian sightings on the day included bottle-nosed dolphin, fox squirrel (1 along Summerhouse Pond Road), many dragonflies, and the usual bevy of American alligators. Recently reported avian species that we did not see included Roseate Spoonbill and Reddish Egret (we'll look again next survey). We also missed seeing Bald Eagle. :-(  My eBird checklist on the day's outing is appended, below, FYI.

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

Friday 30 May 2014 high tide 4.7 ft at 9:38 AM
Saturday 31 May 2014 high tide 4.5 ft at 10:20 AM
Monday 2 June 2014 high tide 4.3 ft at 11:47 AM
Tuesday 3 June 2014 high tide 4.3 ft at 12:33 PM

   Stay tuned for further plans.

Fri 2 May 2014 survey


F 2 May 2014

All,

   I had a great day on Bulls Island today for the ongoing waterfowl/shorebird survey. CEX's owner and Captain Chris Crolley graciously hauled me out to the island along with only three other folks. Because he wasn't sure that he'd have customers staying until the 4:00 PM ferry, I hustled through the survey sites to meet the 1:00 PM ferry and was able to cover almost all of the impoundments. Fortunately it wasn't hot as I didn't even stop long enough for a drink of water until I got back on the ferry to leave.

   44 target species on the day's survey, 71 species overall. My eBird checklist is appended, below. Not bad for an abbreviated survey. Good finds on the day included a Greater Scaup, several Least Bitterns, a Cattle Egret, Wood Stork, Piping Plover, Wilson's Plover, Marbled Godwit, Black Scoter, Bonaparte's Gull, Red-breasted Merganser, Horned Grebe, plus MANY Black-bellied Plover, Semipalmated Plover, Dunlin, Spotted Sandpiper, and Short-billed Dowitcher. 

   Misses (not yet arrived? simply missed?) include Gull-billed Terns, Stilt Sandpiper, Western Sandpiper, Black Tern, and Red Knot.

   Non-avian sightings included alligators by the score, white-tailed deer, eastern pondhawks (dragonflies), butterflies (primarily palamedes swallowtails, I believe), loggerhead sea turtle (its head popped up in front of the ferry), bottle-nosed dolphin, mosquitos, and love bugs (flying solo not coupled).

   One of the best areas today, no surprise because it's almost always very good for shorebirds, was the oceanfront marsh at Jack's Creek. It had a very large mixed flock of shorebirds, primarily Dunlin, Semipalmated Plover, and Short-billed Dowitcher, many of which were well advanced in their molting into breeding plumage. Very surprising, though, was the fact that this marsh had VERY LOW water levels. I finally found why: the low dune line separating the marsh from the beachfront and the ocean has been breached and the marsh largely drained straight into the ocean! 

   On the other hand, recent rains (1.27 inches in just the last couple of days) have raised Jack's Creek (from 4.70 to 5.12 on the water level gauge in two weeks) until it is now spilling over the highest riser and Upper Summerhouse Pond has risen (4.10 to 4.62) and is at the very top of the riser board at the trunk leading to the salt marsh. In both impoundments previously exposed mudflats are now completely flooded again and appear too deep for most shorebirds. 

   Dan and Greg (the USF&WS biologist and maintenance guy, respectively) were busy today spraying the impoundments with herbicides attempting to knock down the invasive Phragmites, and there were volunteers cutting the lawn and painting the Dominick House (by hand with real brushes no less!).. Many of the grassy roads have been mown recently and look good.

   Looking forward at the tide calendar suggest the following dates to consider for our next survey:

Friday 16 May 2014 high tide 5.0 ft at 9:28 AM
Saturday 17 May 2014 high tide 5.0 ft at 10:19 AM
Monday 19 May 2014 high tide 5.0 ft at 12:11 PM

Stay tuned for the next announcement.

Regards,

David
