2013 Fall Migration Banding Results

The 2013 fall migration banding station at the Kiawah Island Banding Station is in the books!  Nets were opened for a total of 98 days (out of a possible 108) from August 15 - November 30th.  The last two weeks of November were extremely windy and 7 days were lost during that time.  The other three days were lost due to bad weather during the first week of the season giving us a stretch of 82 consecutive days of banding in between. 

We banded 4,529 new birds and had 1139 recaptures of 82 different species.  The most commonly banded species were Common Yellowthroats (1,146), Yellow-rumped Warblers (1, 054), and Gray Catbirds (572).  Those three species combined made up 61% of all the bird banded this season!

We banded 9 species never before banded at KIBS:  Eastern Whip-poor-will, Willow Flycatcher, Alder Flycatcher, Ash-throated Flycatcher, Bay-breasted Warbler, MacGillivray's Warbler, Grasshopper Sparrow, Orchard Oriole, and Bobolink.

We increased our effort from 7,220.6 net-hours in 2012 to 9,584.2 net-hours this year.  This increase was due solely to the addition of 3 new nets as we banded exact number of days as we did last fall. 

We also had lots 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. 

Compared to last fall, the number of new birds banded was way down.  There was a decrease in the capture rate from 65.2 birds/100 net-hours in 2012 to 47.3 birds/100 net-hours in 2013 - a net loss of 17.9 birds/100 net/hours.  Interestingly but not surprising, the capture rate of recaptures remained about the same (11.9 birds/100 net-hours in 2013 and 12.2 birds/100 net-hours in 2012).  Most species exhibited decreases in their capture, however there we a few exceptions that actually showed substantial increases.  These included White-eyed Vireos, Red-eyed Vireos, Northern Mockingbirds, and Painted Buntings.

 

The bird of the season has to go to the MacGillivray's Warbler that was banded on October 18th.  This individual represented a FIRST STATE RECORD for that species in South Carolina!

I would like to thank all those that made this season such a great success: my banding assistants (Mattie VandenBoom, Claire Stuyck, Josh Lefever, and Vicki Morgan); the Kiawah Island Conservancy for providing funding for mist nets, banding equipment, and the hiring of 3 banding assistants; the Town of Kiawah Island for allowing me to take on an extremely time consuming project; Kiawah Development 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.      

 

The Final Day of the 2013 Fall Season

I woke up at 5:00am and stepped outside to check on the weather.  The wind sounded like a freight train as it howled through the live oaks.  I turned around, shut off my alarm, and went back to bed.  What an uneventful way to end the 2013 fall banding season.     
I will be putting together a summary post sometime in the next couple of days with the season's totals and highlights. Winter banding will begin around December 10th with banding occurring every 10 days through the end of March. In addition, our third season of winter marsh sparrow banding will begin around December 4th to coincide with the higher (> 6 feet) daytime high tides.  If anybody is interested in helping out with marsh sparrow banding let me know - the more the merrier.

Thanks for following along with us during the 2013 fall migration banding season!  I'm already looking forward to next fall.

Banding Marathon: Another Chat

It was a long day today. . . Blustery winds are predicted for tomorrow (the last day of the fall season) so I decided to take advantage of today's great conditions and pull a sunrise-to-sunset banding marathon.  Bird activity wasn't great but at least it was fairly constant throughout the day.  The bird of the day was a Yellow-breasted Chat - the 2nd one banded in a week!

Yellow-breasted Chat (HY, M)

Other interesting captures included a bunch of returns:

Yellow-rumped Warblers:  11/13/09, 11/18/09, 1/15/10, 11/01/10, 11/13/11, 11/15/11, 12/9/11, 11/4/12, 11/13/12, 11/24/12, 11/24/12.
Gray Catbird:  11/01/12
Northern Cardinal:  11/05/09

By the end of the day I had done the 3/4 mile route to check nets 16 times (not including the opening and closing of nets) plus the 1/2 mile walk in and the 1/2 mile out of the banding station.  My feet were tired but the spectacular view of the sunset over the Kiawah River was well worth it.

A Slow Thanksgiving Morning

The thermometer read 32.3 degrees when I arrived at the banding table this morning. The sand crunched underneath my feet like I was walking on a fresh snow after a hard freeze.  I had to delay opening the nets until around 8:00am due to the cold temperatures.  The wind was fairly calm when I arrived but quickly increased to strong gusts around 20 mph.  This caused me to not open all of the nets as I had planned to do.  The wind then calmed down again around 10:30am but the bird activity continued to be slow and I only banded 5 new bird and had 6 recaptures of 4 different species.

Happy Thanksgiving!

Rain and Wind - No Banding Today

I was not able to band today due to rain and strong winds.  I'll try again tomorrow.

- Aaron

The Calm Before the Storm

I didn't think there was any chance that I was going to be able band today with a huge weather system barrelling its way towards us.  But when I woke up this morning and checked the wind outside - it was actually calm, not the 20mph gusts that were forecasted.  The rain had not reached us yet but it was looming near. As any of the banding assistants will tell you, if there is a window in which I can band, I will, even if it is only for an hour or two.  This morning I was able to get a little over 3 hours in before the rain started but not before banding 10 new birds and recapturing 10 more of 5 different species.         

The Impending Doom

Tomorrow appears to be a wash with rain continuing through the early morning hours and predicted wind speeds between 25-30mph.

No Banding Again Today

Banding was cancelled today due to cold temperatures and windy conditions.

No Banding Today

I was not able to band today due to 25 mph winds.  Tomorrow's predicted winds are forecasted to be around 20 mph with temperatures around the freezing mark.  If I do make it out in the morning, it probably won't be until after 8:00am.

Late Yellow-breasted Chat

With the approaching cold front, bird activity picked up a little bit today with 32 new birds and 11 recaptures of 8 different species.  The biggest surprise of the morning was a Yellow-breasted Chat!  A majority of the chats move through KIBS in August/early September but occasionally there will be a late one.  In fact, there are a few that overwinter along the South Carolina coast every year.  Last year, I banded one on December 20th.  Today's bird had a moderate amount of fat so I bet this one will not be sticking around.    



Yellow-breasted Chat (HY, male)

Snakes are not commonly seen around KIBS but today I saw two beautiful corn snakes.  The first, a 4 footer, was on the ground sunning itself in the trail between net 16 and 20.  It was very cooperative and allowed me to pick it up for a quick photo.  I walked right by the 2nd corn snake as I was checking net 3.  As I was returning from the far end of the net, I noticed it about head high in the wax myrtle about midway down the net.    



Corn Snake #1

Corn Snake #2

 
The weather over the next several days is not looking good for banding.  Wind is going to be an issue again on Sunday and Monday with predicted winds from 20-25 mph.  Rain is in the forecast for Tuesday and Wednesday.

Friday's Results: 11/22/13

The weather finally cooperated and I got back out to the banding station today.  Unfortunately, the birds did not. . . I only banded 12 new birds and had 15 recaptures of 7 different species.  Often this time of year recaptures outnumber new birds - as was the case today.  Among the recaptures today were several interesting returns:

White-throated Sparrow:  3/20/13
White-throated Sparrow:  11/13/12
Song Sparrow:  11/28/12
Yellow-rumped Warbler:  11/24/09

Still Too Windy - No Banding

The wind was still too strong to open the nets this morning.  Tomorrow's forecast is looking much improved with fairly calm winds.  It's been three months since I spent an entire 8 hours in the office in front of a computer, so it will be nice to get back to my "other office" tomorrow.

No Banding Today - Too Windy

The wind this morning was just as strong, if not stronger than yesterday so I did not even bother to try banding today.  Tomorrow is not looking much better but I hope to get for a little while.

Sadly, all of the banding assistants have left KIBS.  I would like to thank them all again for a successful fall migration season!  Their passion and enthusiasm for birds and bird banding was unmatched, and I appreciate all the tireless hours and effort they put into the project.  Their hardwork will not be forgotten.  Good luck Mattie, Claire, Vicki, and Josh!

"American Robin, Listen What I Say, Hey"

Strong northeast winds forced us to close down the nets a little after 9:00am but not before banding 7 new birds and recapturing 2 others of 6 different species. 

Today was Mattie's last day at the Kiawah Island Banding Station.  I would like to thank her for making this a very successful season (and for staying a few extra days to help me out).  She and her expertise will be surely be missed.  I learned a lot from her this season and the contributions that she made during her time at KIBS will not be forgotten.  I wish her all of the luck in the future!

Mattie measuring the wind chord of a Yellow-rumped Warbler


I will be flying solo (unless I get any volunteers) for the last 11 days of the season.  I set a goal at the beginning of  the season to band 5,000 birds this fall.  With 11 days left, I need to average 52 birds a day to get there.  It's going to be a tall order to fill (especially since tomorrow is going to another windy day) but I think it's attainable, if (and only if) we get another strong push of Yellow-rumped Warblers.  If the yellow-rumps don't show up, then I'm toast.    

The following sentence is one that I will probably never type again when writing about KIBS.  The most common species banded today was the American Robin.  Four were captured during the first net round representing all of the age/sex classes except a hatch year/female.  



American Robin (AHY, M)

The photo below shows a good comparison between an adult male and an adult female American Robin.  The male (left) has a blackish head with a bright orange breast with very little pale edging.  In contrast, the female (right) has a brownish head and a pale orange breast with extensive pale edging.  Not shown in the photo, but males will also have a blackish tail compared to the duller/brownish tail of females.       


American Robin -  AHY, M (left); AHY, F (right)

The next photo compares a hatch-year male (left) with the same adult male (right) from above.  Notice that both of these have blackish heads but the hatch-year bird has much more extensive pale edging in its breast feathers.  In addition to the edging on the breast, there was a molt limit within the greater coverts of the hatch-year bird which is what we used to initially age that individual.

The return of a couple old friends

We had a pretty good day with 47 new birds and 16 recaptures of 8 different species.  I had to bail after the 2nd net run for a prior appointment but I left the station in the capable hands of Mattie and Will.  A steady stream of new Yellow-rumped Warblers mixed with a various assortment of recaptures kept them busy most of the morning. 

We had a couple of very neat recaptures today:

1.  A Sharp-shinned Hawk that was originally banded on 4/21/10.      
2.  A Yellow-rumped Warbler that was banded exactly 4 years ago today on 11/18/09.  Today was the only time this individual has been captured since its banding date.  Either he is very good at evading the nets or he is just passing through to a wintering site further south.

Yellow-rumps, Yellow-rumps, Yellow-rumps

Eighteen birds captured on the first net round made Mattie and I think that we may be in for a good morning.  Well . . . the 2nd net round yielded only 2 birds and the 3rd only one.  But, we ended up the day with 32 new birds and 8 recaptures of 7 different species.  Of the 32 new birds banded 31 of them were Yellow-rumped Warblers.  Yellow-rumps will be the majority for the remainder of the season. 

Last year I did a post on how we age and sex Yellow-rumped Warblers.  Rather than reinventing the wheel and replicating that post I will just provide a link to it.  It shows a very detailed description on molt limits used in ageing and the plumage characteristics that we look at in order to determine the sex of individuals.

And we are now down to two . . .

This past week has felt like a scene out the movie Groundhog Day - everyday is pretty much the same.  Ruby-crowned Kinglet, Gray Catbird, Yellow-rumped Warbler, Song Sparrow, Swamp Sparrow . . .

And so it repeated itself again today with 26 new birds and 14 recaptures of 9 different species.  

Today was Vicki's last day at the Kiawah Island Banding Station.  Vicki's contribution this season was essential and I thank her for all of the hard work she put in during the past 3 months.  I wish her the best of luck on the next leg of her journey.

Slow day despite improved weather conditions

We experienced improved weather conditions over yesterday but it still did not produce as many birds as we had hoped for.  The wind chill registered below freezing temperatures at sunrise which prompted us to delay opening the nets for about 1 hour.  The most interesting bird of the day was a somewhat late Painted Bunting.  Most Painted Buntings have left the area by this time of year but we usually catch one or two in November, and it is not unheard of for a few to overwinter along the coast.
