CAPTAIN SAM'S (west end)
Nets were opened for a total of 98 days (out of a possible 108) from August 15 - November 30. We had five more rain days this year compared to last year, including a 3 day stretch (October 3-5) when we received around 20 inches of rain. In combination with extremely high tides this created catastrophic flooding in the area.
We banded 4,770 new birds and had 1,122 recaptures of 83 different species. The most commonly banded species were Common Yellowthroats (1,266), Gray Catbirds (843), and Yellow-rumped Warblers (595). Those three species combined made up 57% of all the birds banded this season!
We also had a lot of recaptures from birds that were banded in previous seasons. It will take a while to sort through all those records to determine how many unique returns we actually had as some of those were undoubtedly captured more than once during the fall.
We increased our effort from 11,565.6 to 12,115.8 net-hours despite banding five fewer days than last year. This increase was due to the addition of 2 new nets bringing us to a total of 25 nets.
We banded 316 fewer birds this fall compared to last year and the capture rate decreased 6.6 birds/100 net-hours from 55.3 last year. This decrease can partly be attributed to the large decrease in Yellow-rumped Warblers this fall. For the first time in several years, the capture rate of recaptures also decreased by 2.2 birds/100 net-hours. The capture rate of recaptures is usually fairly constant only varying by a few tenths each season.
There were 10 days when over 100 birds were banded with 3 of those with over 200 birds banded. The best day was on October 6th when we banded 436 birds and had 20 recaptures. This was by far, the biggest day we have ever had at KIBS!
We banded 2 species never before banded at KIBS: Black-billed Cuckoo and Lincoln's Sparrow.
There were no vagrants banded this year, but some rare and notable species included Black-billed Cuckoo, Red-breasted Nuthatch, Swainson's Warbler, Blue-winged Warbler, Bay-breasted Warbler, and Lincoln's Sparrow. Some notable species absent this year included Eastern Kingbird, Brown Creeper, Wood Thrush, Chestnut-sided Warbler, and Canada Warbler.

LITTLE BEAR (east end)
Nets were opened for a total of 57 days (out of a possible 72) from September 7 - November 17. We had 15 days cancelled due to rain, wind, and/or flooding. The Little Bear site was shut down from October 3-12 due to extensive flooding of the Ocean Course which is the only way to access the site. This was unfortunate because the days after the rained stopped beginning on October 6, Captain Sam's experienced huge volumes of birds moving through the site. Little Bear missed out on all this activity but it was sure nice to have all "hands-on-deck" at Captain Sam's during that time.
We banded 2,370 new birds and had 410 recaptures of 70 different species. The most commonly banded species were Gray Catbirds (563), Common Yellowthroats (424) and Yellow-rumped Warblers (423). Those three species combined made up 59% of all the birds banded this season!
We logged 3,552.4 net-hours out at Little Bear this fall. We started out with 10 nets but that number increased to 16 as the season progressed and we learned more about the site.
Little Bear had a very good capture rate at 78.2 birds/100 net-hours - much higher than at Captain Sam's. There were 11 days when over 75 birds were banded with 3 of those days with over 100 birds banded. The best day was on October 13th when we banded 118 birds and had 5 recaptures.
We banded 3 species never before banded at KIBS during the fall at Little Bear: Green Heron, Saltmarsh Sparrow, and Seaside Sparrow.

I would like to thank all those that made this season such a great success: the banding assistants (Mattie VandenBoom, Chris Snook, Sean McElaney, Casey Weissburg, Michael Gamble, Nancy Raginski, and Ryan Donnelly); the Kiawah Island Conservancy for providing funding for the hiring and housing of 7 banding assistants; the Town of Kiawah Island for allowing me to take on an extremely time consuming project, and the funding for one banding assistant; Kiawah Partners for allowing access to their property; and finally to all the volunteers that donated their time to either come out and help or just to observe.
