Th 22 Jan 2015 survey

Th 22 Jan 2015


   Wil Christenson and Rachel Jones joined me today for the ongoing Bulls Island waterfowl/shorebird survey. With thanks to Coastal Expeditions for their generous and ongoing support, we were able to get out to the island and back on our own schedule. Good thing, too, as we needed more time than usual to count all the waterfowl hanging out on Jack's Creek.

   We tallied 50 species on the survey proper, 80 species on the day's outing; our two eBird checklists are combined and presented below, FYI. Waterfowl were very plentiful, especially on Jack's Creek. We tallied many Bufflehead, Gadwall, American Wigeon, Ruddy Duck, Hooded Merganser, Northern Shoveler, Green-winged Teal, and Red-breasted Mergansers and added small numbers of Northern Pintail, Canvasback, and Ring-necked Duck. 

   Unfortunately shorebirds numbers were way down with very few seen on either the North Beach or the oceanfront marsh at Jack's Creek. Even the dropping water levels in Jack's failed to attract shorebirds there. A nice shorebird find was a Wilson's Plover. Since we moved the survey up by a day to avoid getting drenched in Friday's predicted rain, the high tide was earlier than we typically  plan for the surveys; perhaps we missed our usual target high tide plus-or-minus 2 hours and thus missed many of the shorebirds that had gone off foraging.

   There were a few other nice finds on the day including Green Heron, Glossy Ibis, Great Black-backed Gulls, all three marsh sparrows, and a Roseate Spoonbill. 

   Non-avian sightings included white-tailed deer, eastern fox squirrel, numerous bobcat tracks, bottle-nosed dolphin, and American alligators.

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

Fri 6 Feb 2015 high tide 5.0 ft at 8:59 AM
Sat 7 Feb 2015 high tide 4.8 ft at 9:32 AM
Mon 9 Feb 2015 high tide 4.5 ft at 10:41 AM
Tues 10 Feb 2015 high tide 4.3 ft at 11:22 AM
Wed 11 Feb 20115 high tide 4.2 ft at 12:10 PM

Stay tuned for further plans.

Th 15 Jan 2015 mid-winter Bald Eagle survey

Th 15 Jan 2015


   Here's a bonus report, below, that Wil Christenson and I submitted yesterday from our efforts on Bulls Island conducting both the mid-winter Bald Eagle survey and the mid-winter waterfowl survey. Thanks to the generous support of Coastal Expeditions, we got out to the island early and were able to stay late. And we needed all that time to count the ducks on Jack's Creek. 

   Both eagles and ducks were well represented on the island; Jack's Creek, in particular, was brimming withwaterfowl. The only waterfowl species that we missed were Canvasback, Long-tailed Duck, Blue-winged Teal, Greater Scaup, and the three scoters. Bird of the day, however, was Green Heron--five total seen in two different locations. After having seen no alligators on our previous survey, we did see one gator braving the cold yesterday. Also seen were dolphin cresting the surface of Bulls Bay.

   Arrangements are under way to construct a new, long dike across Jack's Creek. I don't know when construction begins, but it may last several months. Should be interesting to follow changes in the waterfowland shorebirds during and after construction.

   Through the generous and ongoing support of our waterfowl and shorebird surveys from Coastal Expeditions, we have a newfound flexibility in conducting upcoming surveys. The tide table suggests that Friday 23 Jan 2015 (5.9 ft high tide at 9:49 AM) should serve the survey well. We will be leaving Garris Landing slightly earlier than usual, likely about 8:30 AM, and returning slightly later than usual, likely by 5:00 PM or so. Wil and I will have space for one additional person; first email reply to this message gets the seat for the Friday 23 Jan 2015survey.

Fri 9 Jan 2015 survey

Fri 9 Jan 2015


   Wil Christenson and Pam Ford joined me today for the ongoing Bulls Island waterfowl/shorebird survey. USF&WS got us out to the island early (thanks, Greg) and safely back (thanks, Sarah). 

   Jack's Creek water levels have dropped appreciably (and will drop much further) in preparation for beginning construction of a new dike across that impoundment. The water level sure seemed to make the Gadwall happy as I probably saw more Gadwall butts up in the air than any other position. The Willet and Greater Yellowlegs also seemed to appreciate the water level judging by their high numbers in Jack's. The water level at Upper Summerhouse Pond may be slightly higher (impression only--I'm sure that a new staff gauge to measure water levels will be installed with the upcoming trunk installation); there were no shorebirds at USP and many fewerwaterfowl than over the past two months of terrific waterfowl counts there.

   We tallied 42 species on the survey proper and 61 species on the whole day's outing. Our eBird checklist for just the island (i.e., not the boat ride out for which I submitted a separate checklist) is appended, below, FYI. Jack's Creek and the oceanfront marsh were the best of the survey today followed closely by the North Beach. We saw high numbers of Pied-billed Grebe, Black-crowned Night Heron, Bufflehead, Gadwall, Ruddy Duck, Hooded Merganser, American Coot, Western Sandpiper, Forester's Tern, and Red-breasted Merganser. There were finally a few shorebirds on the North Beach today, most of which appeared to have flushed from the large sand bar in Bulls Bay to the North Beach right as we walked out. The same sandbar had a Great Black-backed Gull. 

   The bird of the day we didn't even see, however. Sarah Dawsey, the Refuge Manager, reported 3 Roseate Spoonbills from a corner of Jack's Creek that we skipped on our slightly foreshortened survey today. "Very pink," she said. Thanks for your report, Sarah.

   Avian misses of note included American Black Duck and Redhead.

   And one that fooled us…we heard a persistent, squeaky, croaky note coming from the deep woods right beside the parked truck. All three of us were intensely focused on this sound trying to identify it. Wil moved into the thick pine forest steadily closing in on the sound wondering why the bird didn't flush. When he came right on top of the continuing creaky call, he noticed the downed pine limbs moving in time with the croak and finally determined that it was wind-blown limb-on-limb movements causing the creak. Wonderfully chagrined and laughing out loud, we each did our own mental exercises to remember that sound so as not to be fooled again. We were ready to declare a new species…pine bough bird (an auditory cousin to leaf birds, stick birds, and stump birds that everyone is familiar with).

   Despite the cold temperatures there were a few mosquitoes about today, but the most interesting non-avian wildlife sighting was a clutch of brown bats that Sarah found huddled in a sink in the work shed. The bats were very sluggish (likely from the cold?), hardly moving at all. They were not longer than my finger, and their fur was surprisingly fine and soft to the touch. We also saw several Atlantic bottle-nosed dolphin (both in Bulls Bay and off the North Beach) but didn't see the first American alligator (Wil and Pam, do you recall seeing any alligators?).

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

Th 22 Jan 2015 6.1 ft high tide at 8:59 AM
Fri 23 Jan 2015 5.9 ft high tide at 9:49 AM
Sat 24 Jan 2015 5.6 ft high tide at 10:41 AM
Mon 26 Jan 2015 4.9 ft high tide at 12:32 PM

Stay tuned for further plans.

   In a final wrap up to 2014, I'd like to thank the 19 of you who volunteered with me over the past year to complete the surveys. Together you contributed an estimated 229 hours and 45 minutes of your time to the USF&WS in service to the waterfowl and shorebirds of Bulls Island. On behalf of all of them…Thank You!
