The Kiawah Conservancy Visits! And a Station First Barn Swallow!

 Captain Sam's:

Today at Captain Sam's was a very special day, we had members of the Kiawah Conservancy come out and join us for banding. Thankfully the winds had changed slightly from what they had been for the last few days. This provided us with some birds to show to the members what we do and show off some neat species. It's always a good time when you get to talk birds with other people in the community who care for the well-being of the creatures some of us spend our time trying to understand. Just shortly after everyone left, we were however able to catch a recapture Mourning Dove that was banded last year as an after hatch year bird. This means the dove we caught today has been calling Kiawah Island home for at least three years now! It's great when you get unexpected recaptures from years prior, just a little check in from our feathered friends. Another exciting bird we caught today was a Traill's Flycatcher. I myself haven't seen them in the hand until I came here to Kiawah, so it has been nice to look at them closely and do the measurements needed to try and figure out if it's an Alder or Willow Flycatcher. Sadly our bird today was, like many, in-between the ranges for both so unsafe to call it one or the other. This bird inspired today's haiku.

Thanks again to Taylor, Sarah, and Collie for coming out to the banding station! If anyone wants to get involved with the Kiawah Conservancy they can do so here. Tomorrow looks like it's going to be a very windy day with the wind bands coming from Ida, that being said it's hard to say what will or won't get blown in because of it, so stay tuned for these next couple of days!

Little Bear:

Today at Little Bear, we didn't catch a lot, but we made up for that with a station first, BARN SWALLOW. Barn swallows are one of the most numerous species we see at the banding station, but they are seldom thought of as possibilities to be caught in our nets. They tend to stay high and their agility, vision, and knack for avoiding our lanes generally keep them as distant sights at the banding station. However, on our first net run, I was stunned to see a barn swallow in one of the bottom trammels of a mist net. I was smiling and nervous as I put the bird in the bag, because I knew it was unusual, but unsure as to how infrequent until I met back up with Josh at the table.

After processing an assortment of other species, we saved the swallow for last. Josh carefully banded and measured the bird and we aged it to be a hatch-year based on its very short tail, wing, and fork length. Afterward, we were able to snag some photos of this beautiful bird. I know that for the rest of the day I watched the barn swallows streaming overhead with a newfound appreciation.  

After the swallow, things slowed way down and we processed only a handful of birds. We did catch one of my favorites, a Downy Woodpecker, and got to see this awesome bird completing its preformative molt.

FOS Northern Parula

 Captain Sam's:

Today was a slow but steady day. We had a total of 22 birds! Slowly we are increasing our numbers but not yet. I am hoping something gets pushed over to us as the storm Ida moves north. Also praying for everyone that was affected by the storm and that they are safe as well. 

Hopefully tomorrow Captain Sam's will have their Northern Parula too! 

-Kristin

Little Bear:

It was a little cooler as we opened the nets this morning (only 74 degrees!), and bird activity seemed to be up from the past few days. We had a relatively busy first net run, that matched our capture count from yesterday (14 birds), highlighted by 2 Eastern Kingbirds

Eastern Kingbird- these birds almost never sit still for photos,
and this is by far the best picture I've gotten of the 4 we've caught so far this month

After the first net check, the sun warmed things up fast and our capture rate dropped quickly- we only caught another 7 birds for the remaining 4 hours that we were open. But we had a few goodies, like a Prothonotary Warbler and our first-of-the-season (FOS) Northern Parula.

We're optimistic that things will continue to pick up as this week goes on- hopefully our first 'big day' isn't too far off!

Sunrise Screech-owl

 Captain Sam's:

Expecting another extremely slow day, today's banding yielded a few more birds than we thought we would get. We caught 15 birds today, which isn't too terrible for a hot August day. The first net run just after sunrise started the day off well, with 6 birds - and one of those was an Eastern Screech-owl! It was a hatch-year rufous morph, and still had some fluffy feathers on its head, just like the one we caught 10 days ago on 8/19/2021. Unfortunately it managed to wiggle away while it was being weighed, so we weren't able to get a photo of this one. Hopefully we'll catch more as the season goes on!

-Kandace


Little Bear:

Walking out to Little Bear today, Josh and I had low expectations, but were eager to see how the day would turn out. To our surprise, on the first net run, we each found multiple birds of a few different species. This was such a nice surprise from the day before that even processing these few numbers felt like a treat. 

We recaptured a Traill's Flycatcher and measured everything to key it to its specific species, but unfortunately, the bird fell somewhere in between the marks for Willow and Alder Flycatcher, Although we were both fairly certain it was a Willow, it is best to leave it as Traill's unless we are able to definitively identify the bird. 

We caught a few migrant species like Northern Waterthrush, American Redstart, Ovenbird, and Common Yellowthroat. These were all somewhat unexpected given the direction of the winds these last few days, but much appreciated. 

The Northern Cardinals and Carolina Wrens continue to fill up the nets. Dominated by hatch-year birds, I am loving the chance to appreciate these species while I can.

There are still quite a few resident and breeding species that we have yet to get in the nets at Little Bear. A tantalizingly close Eastern Towhee and Blue-gray Gnatcatcher come to mind right away. Hopefully, the station starts to welcome newcomers on their journey south and also attract the local birds who have seen us around the entire season already.

Is it a bug? A leaf? No, it's a hummingbird!

Captain Sam's:

Today at Captain Sam's we expected the day to be much like yesterday was but to our surprise it was slightly more pleasant in temperature and humidity, still quite hot but just not as bad. Thankfully this slight difference along with other forces also allowed us to catch a few more birds than yesterday. That being said we still did have a slightly shorter day than last week. As a nice surprise, I was walking a net run I noticed something green in the top part of one of our nets. On first approach I thought it was a leaf I was going to extract so birds can't see the invisible wall of net, but when I got a little closer I noticed it was actually a Ruby-throated Hummingbird! I've handled this species before but not through the eyes of a bander observing molts and such so it was pretty exciting! Thankfully I've banded Black-chinned Hummingbirds out west and had the skillset to carefully extract this delicate little bird. The bird we caught today was an after hatching year female, meaning she is a year or older in age, sadly we aren't permitted to band these little ones. Some things that pointed to this being an after hatching year (AHY) female was the amount of white in her tail and overall tail shape. In males they're much more pointed/forked with no white, and in hatch year birds the tail looks similar to an adult female but has a more pointed/forked tail. Below I've added a shot of the tail next to one of charts so you can see what we saw. Another thing that initially told me this was an AHY bird was when you look extremely closely at the bill you'll see small marks in the bill called corrugations. In HY birds they continue down more than half the bill and in AHY birds you'll see little to no corrugations. It's always a neat group of birds to look at, under poor light conditions you might see them as dark green to black but in the right light you'll experience the amazing emerald green structured feathers they have. It also inspired me to write two haikus and since I can't decide which one I liked better I'm posting both!

Little Bear:

We had an arduous, sweaty, and thankfully short session at Little Bear this morning. The heat and humidity combined for a 'real feel' of 91 degrees by sunrise, and we hoped to at least catch a few birds before undoubtedly having to close early. A couple juvenile Northern Mockingbirds and Carolina Wrens decided to show up in the nets and give us something to do. But overall, it was one of the unavoidable slow and hot days that Little Bear always has early in the season. We're already counting down the days to the predicted shift in winds later next week.

A Meal Fit For A Queen

Captain Sam's:

Today was a very very slow day. We had a total of 6 birds making it an early closing time for us. 

During our departure for the day we got to see a female jumping spider having a wonderful feast with this cicada! 

Jumping spiders are basically the only spiders that I consider "cute." Being little and fuzzy gives them a nice welcoming look. 

Check out this link on treehugger.com to see some unique facts about jumping spiders. 

Hopefully tomorrow we'll see an increase, but based on our weather conditions we are looking at yet another slow day.

-Kristin


Little Bear:

Today was my first day out at Little Bear after spending the first bit of the season at Captain Sam's. This meant that I inevitably took a few wrong turns, stumbled into unknown obstacles, and checked my map like a lost tourist on a roadtrip. However, by the end of the day I started to understand where the roots that liked to trip me jut out from the ground and began to appreciate the beauty of the Little Bear site. It is different in that many of the nets are more exposed to wind and sun. This forced us to close down nets sporadically throughout the day as some were heating up disproportionately fast. 

Josh and I made the most of our day out there, but that yielded very little as far as birds go. We caught 8 birds in our nets, including a few after-hatch-year female painted buntings. These birds had extremely worn feathers that made it difficult to spot the molt strategy. They were growing in bright green greater coverts and as Josh pointed out to me, they were molting their flight feathers in a definitive and symmetrical pattern opposed to the eccentric strategy of hatch-year birds. 

We caught one Traill's Flycatcher and while Josh banded it, I raced around making sure I hadn't left any nets unfurled while I was closing. I am really excited to see what the next few days have in store. Even if the bird numbers aren't great, I can never complain about a day spent outside.

Saved by the Cuckoo

 Captain Sam's:

Today was our first "classic" August day for the banding station with a total number of 11 birds caught. We had just been so fortunate to have these past few days that were so plentiful they spoiled us. With that said it allowed us to take very meticulous looks at the individuals we did catch. Of the birds caught today most notable was a new hatching year Painted Bunting! So our group of "triplets" might've been the quadruplets and we just hadn't caught this youngster yet, or this bird is from a different group entirely. Here's to hoping it picks back up again sooner rather than later!

Are the triplets quadruplets

Or are you new here

- Nathaniel


Little Bear:

Our slow, hot August day yielded very few birds in the nets (8 total, to be precise). Each time we saw a Painted Bunting in a net, we were way more excited than we would usually be. Just as were giving up hope for the day and were about to close nets, Josh extracted a first-of-season species for Little Bear from net 1: a Yellow-billed Cuckoo! Striking to see in the field while birding, they're even more captivating in the hand. It was a hatch-year, and was making quite a ruckus, but it was awesome to see its long tail and unique bill from in the hand. Thanks, young Cuckoo, for the nice surprise at the end of the day (even though you were uncooperative and would not pose for a nice photo).

Empidonax Enigma

 Captain Sam's:

Today at Captain Sam's, we saw a dip in the production of the last few days. This gave us time to look at some interesting species and learn more specifics about aging and sexing. The most fascinating bird from today was our only empidonax flycatcher. This is a group of flycatchers that all resemble each other in the field. Often times, vocalizations are the only reliable way to identify them if not banding. Upon bringing the bird back, I had a pretty good idea that this bird was a "Traill's" Flycatcher, and was hoping that we could identify it a step further. Originally, Traill's was its own species, but has since been split into alder and willow flycatcher. Vocally, the two are distinct, and measurements can sometimes separate the species in the hand. However, many like our bird fall in a gray area and are left as "traill's". 

We took many different measurements such as the longest primary to the longest secondary, the difference in length between the 6th and 9th primary, and so on. None of it was conclusive enough to identify the species... If only it had sung. We were able to age this bird as a hatch-year due to the buffy greater coverts. These would be much whiter on an adult bird. 

Hatch-year unknown "Traill's" Flycatcher

The last few days we have been catching three very young painted buntings. Fairly recent fledglings still growing in their juvenile plumage. I nicknamed them the "triplets" as they all look identical and seem to fall into the same net pockets together. I'm really excited to watch these young birds grow and eventually (sadly) leave Captain Sam's. 

Although the winds look to be pushing in from the East in the next few days, I am hopeful that we'll be able to catch some more fun birds. 

-Ben

Little Bear:

With the shifting weather patterns, and having had a slower day at the station yesterday, expectations were pretty low as we opened nets at Little Bear this morning. But the nice thing about low expectations is that they're easily exceeded, and that's exactly what ended up happening. We ended with a modest total of 28 birds captured, and had a few nice highlights, such as our second-of-the-season Eastern Kingbird (just us uncooperative for photos as the first), and a more photogenic adult male American Redstart. The 'frosty' white and orange tips to the body feathers is fairly common on adult male Redstarts that have recently finished molting (replacing feathers before migrating). These feather tips will wear off during the winter, resulting in the jet-black and orange birds that are depicted in your field guide, and seen during the spring and summer.

A Veery early Veery

 Captain Sam's:

We continued to catch a decent number of migrants for mid-late August today with 33 new birds and 10 recaptures of 18 different species.  It appears that this will mostly likely come to an end for at least the next several days.  There is a high pressure system sitting over the eastern half of the US which will keep us hot and humid.  Along with that, we will likely see a wind shift to more of an easterly direction.  For the last few days, we have had winds predominately out of the west and southwest.  These westerly winds help to push migrant to the coast.  Alternatively, easterly winds push birds away from the coast and away from us.  

Highlights from today included 3 more first-of-the-seasons:  Acadian Flycatcher, Eastern Wood-Pewee, and Veery.  Since 2009, we have banded 193 Veeries.  Today's bird is the earliest date that we have ever captured one.  We have only had two other August records both occurring in 2012 on 8/30 and 8/31.  Peak migration for Veeries occur during mid to late September with birds mainly arriving in early September.  By the end of October, most Veeries have reached their wintering grounds in South America.

Little Bear:

Our luck with overcast, cloudy days ended today as it was hot and sunny, so we didn't get as many hours of banding in as we would have liked. But we still managed to catch another first-of-season species for the Little Bear station: Common Yellowthroat! We caught two hatch-year birds that were rather plain and dull. No black face-mask feathers were growing in on either bird, so we were unable to definitively sex them as either male or female. I'm excited to catch (many!) more of these sneaky warblers as the season goes on, and learn all about their molt strategies, and personalities.
