2014 Fall Migration Banding Summary

The 2014 fall migration banding station at the Kiawah Island Banding Station officially ended yesterday!  Nets were opened for a total of 103 days (out of a possible 108) from August 15 - November 30th.  Despite a very rainy September and October, we only had to cancel banding on five days due to bad weather.    

We banded 5,083 new birds and had 1,334 recaptures of 80 different species.  The most commonly banded species were Common Yellowthroats (1,217), Gray Catbirds (1,046), and Yellow-rumped Warblers (843).  Those three species combined made up 61% of all the birds banded this season!

We banded 6 species never before banded at KIBS:  Cooper's Hawk, Clapper Rail, Eastern Screech-Owl, Sedge Wren, Yellow-throated Warbler, and Rose-breasted Grosbeak.

We increased our effort from 9,584.2 net-hours in 2013 to 11,565.5 net-hours this year.  This increase was mainly due to the addition of 3 new nets along the dunes and that we banded on 5 more days than last year.  

We also had a bunch 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 banded 554 more birds this fall compared to last year but the capture rate decrease by 3.4 birds/100 net-hours.  This decrease is due to the increased effort recorded this year.  Interestingly but not surprising, the capture rate of recaptures remained about the same (11.5 birds/100 net-hours in 2014 and 11.9 birds/100 net-hours in 2013).

There were no rarities banded this year - so breaks the 3 year streak of Bell's Vireos.  Other notable species absent this year included Baltimore Oriole, American Goldfinch, Swainson's Warbler, Kentucky Warbler, Canada Warbler, Wilson's Warbler, Least Flycatcher, Yellow-bellied Flycatcher, and Eastern Kingbird    

The following is a photographic recap of the some of the highlights from this season:

I would like to thank all those that made this season such a great success: the banding assistants (Mattie VandenBoom, Libby Natola, Matt Zak, and William Oakley); the Kiawah Island Conservancy for providing funding for the hiring and housing of 3 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.
