The Butter-butts Keep Buttering

 CAPTAIN SAMS

This fall has been exceptional in terms of overall bird numbers, species richness, number of foreign recaptures, etc.  Pretty much every season-long metric has been surpassed already and we still have an the month of November to go.  After 2.5 months of banding we have banded 4,778 birds.  In the past 16 years of banding at Captain Sam, there have only been three years where we have banded that many birds during the entire season - 2022 (5,704), 2017 (4,795), and 2014 (5,083).  The month of November can sometimes be hit or miss as most of the neotropical migrant have already passed us by.  There is usually 1 or 2 more moderate pushes of migrants into our area during the first half of November but that is mostly going to be made up of Yellow-rumped Warblers with Ruby-crowned Kinglets, Hermit Thrushes, and sparrows filling in the remainder.  

Today was quite slow and we only banded 21 new birds and had 14 recaptures.  A cold front is pushing its way across the US, but it seems the high pressure system sitting over the Southeast may be stronger and will prevent it from reaching us or drastically weaken it.  The next cool down doesn't look like it will happen until the end of next week.  There is a wind shift to the north on Saturday which may help bring us some new birds.

LITTLE BEAR

We ended our day with a total of 37 birds. Today picked up a little bit more than yesterday because we managed to catch a few roaming flocks of Yellow-rumped Warblers throughout the station.  From here on out, they will most likely be the most abundant species we catch each day. In late fall and winter, yellow-rumps form small to large foraging flocks and we will catch several of them in a net a one time.  
We didn't have much diversity today and only had a total of 8 species captured at our station. Even on these slower days it is nice to enjoy hearing all the birds chirp as they fly over the station. Today we saw a flock of Eastern Bluebirds  and a decent amount of Tree Swallows fly over. I hope that we might catch either of them this season but I'm just gonna keep thinking that Little Bear is just to cool for them.

Tomorrow seems like it might be much of the same, so we shall see what our nets will catch in the morning.

This Sedge Didn't Have an Edge

  CAPTAIN SAMS

It was a pretty good day out at Captain Sams, albeit a bit slow. We ended the day with 52 birds (43 new and 9 recaptures). Unsurprisingly, our main catch of the day were Yellow-rumped Warblers with 34 new and 1 recapture. This recapture was a bird that was actually banded earlier this year on March 5th. We had a few other older recaptures today as well, including a Song Sparrow originally banded on November 16th, 2021 and a Common Yellowthroat that was banded on October 23rd, 2023. Interestingly enough I was the one who banded the yellowthroat last year as a hatch-year, so it was pretty cool to see that this bird survived and is coming through the station once again.

We also had a first of the season today, a Sedge Wren! These small birds are particularly hard to catch due to their ability to slip right through our nets. Most years the crew has to try to target these birds and will sometimes even use two nets sitting parallel to each other in order to catch them. But this year we got lucky and managed to catch this individual passively. It had almost slipped out of the net by the time I got to it, but luckily I was able to reach it before it got away. It was pretty cool to see this tiny bird up close! 



Sedge Wren (hatch-year, sex unknown)


Today we reached 100 species banded between the two stations for this year. The record for the most species banded for KIBS in one season is 105, so we will have to see if we can snag 6 new species before the season ends!


- Natalie






LITTLE BEAR

We had a nice overcast start to the morning before it heated up as it often does at Little Bear. Today we banded 12 new birds and 10 recaptures of 10 different species, of which was mostly our usual sparrows and catbirds. Over the past couple weeks, we have been recapturing a number of our Gray Catbirds, and a few of them have been putting on more fat which has been encouraging to see! We are hoping that they'll fuel up and continue their journey soon.

Late Arrival Surprises

 CAPTAIN SAMS

Although the season is starting to wind down, that doesn't prevent us from enjoying ourselves on slow days like today. Shortly after opening the usual array of nets at Captain Sams, we decided to open up the seasonal swallow nets in hopes that Tree Swallows will take time to feed on the Wax Myrtle trees nearby. The banders at KIBS strategically set nets near wax myrtle trees that have an abundance of berries in hopes that when they do come to feed some of them might find their way into our nets. Tree Swallows will swarm these trees to feed on their berries when temperatures are cold and flying insects are not active. Only certain species, and very few, can properly digest these berries as they have a waxy coating protecting them. Fortunately for the Tree Swallows, they are able to digest and substitute these berries for insects when temperatures are cold and their typical prey item is not available. Unfortunately for us, we didn't catch any today. Hopefully we will have an opportunity in the future to attempt for them again. 

In total today, we captured 29 new birds and 9 recaptures for a total of 38 birds. Notable species included a House Finch, a late Northern Waterthrush, and yet another Brown Creeper. As October comes to a close, we are starting to see less and less passing migrants and more wintering arrivals. We still likely will see a few more migratory birds before the end of the season and are eager to see what shows up. Until some of those late migrants find our nets, we continue to enjoy the newly arriving winter birds that will make South Carolina their home for the winter.

- Noah Nei


LITTLE BEAR

Today was still a slower day with our busiest part of the day being the first 2 runs in the morning. We luckily had a flock of Myrtle Warblers (Yellow-rumped Warblers) find our nets. We ended the day with a total of 46 birds and only 8 of them were recaptures. We did add a new species for Little Bear, a White-crowned Sparrow. I was hoping for one of them to show up in our nets soon. 

Anther species that was a fun catch is a Hooded Warbler that showed up in our nets. This is a late catch that was not expected at our station. They typically are captured during our first month and maybe halfway through October but this late. I know there are some birds that manage to migrate late but it sure is fun to find one in our nets.

The Birds are "Butter"-ing us up

 CAPTAIN SAMS

Today was slightly slower than yesterday with 55 new birds and 24 recaptures. Just like yesterday Yellow-rumped Warblers were our most common catch, however instead of catching 101 of these "butter butts" we only got 29. Regardless, it was still a good day of banding. The Tree Swallows are still out and about, and this morning we set up 2 more swallow nets to be used when they decide to descend to feed on the wax myrtle berries. Tree Swallows will typically feed on bugs high above the canopy, but when insects are not present (usually due to cold weather) they will descend to the trees to eat some berries. We hope to catch them around the wax myrtle trees while they feed. Time will tell if we will get lucky with some Tree Swallows this year!

We also had a surprising amount of Common Yellowthroats today. For the last week or so we've only been catching a few each day but today we had 6 new and 2 recaptures. This is, of course, a far cry from the days earlier this season where we caught 100 yellowthroats in a day, but it is interesting to see this tiny push of them so late in the season. Overall October was a great month of banding, and I am interested to see what we catch during this last month!

- Natalie








LITTLE BEAR

It's warming up again at Little Bear! It nearly hit 80 degrees by the time we left site, and the mosquitoes sure are here for it. We had a slow but successful day of banding, with 27 newly banded birds, and 13 recaptures. Myrtle Warblers, Gray Catbirds, Song and Swamp Sparrows are most of what has been passing through the station these days, with a surprisingly regular appearance of a Yellow-billed Cuckoo or two. The contrast of species we encountered earlier this season compared to what we're seeing now is stark, and it is felt in studying (and struggling) with new molts. But recognizing molt patterns has gotten easier as I have seen and learned more about them here, and this change definitely allows more opportunity to practice.

Myrtle Sunday

 CAPTAIN SAMS

It was a lot busier today with 128 new birds and 7 recaptures of 18 different species. While opening nets, we heard constant chips from hundreds of Yellow-rumped Warblers migrating over the station. We ended up capturing 101 Yellow-rumped Warblers out of the 128 new birds captured. We also enjoyed watching a couple thousand Tree Swallows circle around the station all morning and come down on a wax myrtle bush on the edge of the marsh and strip it of its berries. 


-Michael



LITTLE BEAR

It was another good day at Little Bear today, we caught 44 new birds and recaptured 11 for a total of 55. It started off fairly warm but cooled down unexpectedly as we continued netting later into the day. Unfortunately, this weather shift didn't seem to be in our favor and Little Bear slowed down dramatically during the latter half of the day. It is typical for Little Bear to be busy during the early hours of the morning, but does often slow down as the sun rises and heats up the dunes. 

Today, we managed to catch Little Bears second Yellow-bellied Sapsucker for the season. Sapsuckers are the only migratory woodpecker in the eastern United States and will spend their winters in South Carolina but are found further north during the breeding season. We captured a hatch year male, who showcased some remaining juvenile feathers within his body plumage but had also partially molted into his new formative plumage. This is only Little Bears second Sapsucker of the season, so we were all quite excited when it showed up in our nets.

Slow and Steady Wins the Race

 CAPTAIN SAMS

As we began our small trek from the beach to our station, we heard a familiar beep from our radio telemetry antennae... the Bobcats are back! We followed a radio-collared individual for a good portion of the morning, monitoring a few nets nearby. This proved to be an easy task on a slow day, with 22 new birds banded and 9 recaptures. 

Radio Telemetry is a helpful technique for tracking animal movement and behavior. It can be used on a variety of species, since transmitters can be specially sized and fitted; Bobcats wear their transmitters as a collar, turtles get tagged on their shell, and there are a variety of harness styles available for birds big and small. 

On Kiawah Island, Bobcats are monitored with the goal of identifying habitat use patterns through the day and night, locating dens, as well as collecting information on their survival and dispersal. Read more about this local project here.

3 Element Yagi antennae and receiver

We use a Yagi antennae to pick up signals from the transmitter. The antennae needs to be tuned to a frequency that is only emitted by the study animal. A receiver is attached, which helps the user collect bearings by playing a "beep" signal that increases in volume when the antennae is pointed towards the study animal. A numerical value is also shown on the receiver to further indicate distance from the signal source.

Despite the limited bird activity, today was well spent brushing up on a research staple skill!

-Lisa Viviano


LITTLE BEAR

We were greeted this morning with a heavy layer of fog over the golf course which gave us a great spooky season October feeling. Luckily the fog burned away as the sun rose, and revealed a beautiful sunrise out on the beach. Our first two net runs yielded us about 30 birds but things slowed down drastically after that. Overall we caught slightly less birds than yesterday (28 new and 9 recaptures for a total of 37). We caught many of the usual characters, including the increasingly common Yellow-rumped Warblers, the classic Gray Catbirds, and a lone Common Yellowthroat. We also caught 4 Swamp Sparrows and 2 Song Sparrows, I am a huge sparrow fan so I'm always happy to see some coming through the station. 


Swamp Sparrow (after-hatch year, sex unknown)


Most of the neotropical migrants have already made their way past South Carolina but we are still catching a few stragglers here and there, including a Black-throated Blue Warbler that we caught today. As the season progresses these birds will become even rarer until eventually they have all made their way through, but it is always fun to catch a few individuals who are running a bit late. As winter creeps ever closer I am excited to see what other species we will catch!

First-of-the-Season Black-throated Green Warbler

 CAPTAIN SAMS

As predicted, we had an uptick of migration activity last night.  We were greeted by the sounds of many migrants (mainly Yellow-rumped Warblers) flying over the banding station as we opened the nets in the dark.  Not surprisingly, Yellow-rumped Warblers made up a huge percentage of our catch today with 63 of them.  In addition, we captured two returning yellow-rumps that were banded last fall.     
We ended the day with 89 new birds and 13 recaptures of 19 different species.  The highlight of the day was a Black-throated Green Warbler (BTNW).  We don't band that many BTNWs.  In fact, in the 16 year history of KIBS, we have only banded 18 prior to today.  

Black-throated Green Warbler (hatch-year, male)

Armadillos are a fairly new addition to the fauna of Kiawah Island.  They arrived on Kiawah about 10-12 years ago and now are very common and have expanded across the entire island.  Because they are mostly nocturnal, you don't see them very often but one was out and about today rooting around the banding area between net 15 and 25 in search of food.  It was oblivious to my presence and walked right up to me as it nosed it way though the leaf litter. To compensate for poor vision, armadillos have an excellent sense of smell which they use to help navigate them through their surroundings.    

Nine-banded Armadillo

LITTLE BEAR

Today was a slower day than yesterday with only a total of 48 birds banded. We definitely have seen a drop in the amount of Gray Catbirds that are captured. It is nice to see more of our wintering birds show up. We didn't add any new species, but our highlight species for the day was a nice young Cape May Warbler and also an Indigo Bunting. I think overall it was a good day. We watched a bunch of Tree Swallows fly over us, taunting us by just skimming over the tops of our nets but it was still a sight to see.
