Brown-headed Nuthatch (Sitta pusilla): Nest Building?


April 5th. On my recent walk from the Section B parking lot to the dam at Fort Yargo State Park, I heard a bird pecking softly on the trunk of a tree. 


After looking around a bit, I spotted a small bird on a nearby snag. 
  

I was excited to see a Brown-headed Nuthatch (Sitta pusilla). The snag wasn’t too far from the trail. There was a large tree a couple of yards off the trail and I decided to try and use it as a ‘blind’ to get closer to the bird. 


I thought I might be able to brace myself against the tree to photograph the nuthatch’s activity. Not so; a Poison Ivy (Toxicodendron radicans) vine was climbing the tree. Nevertheless, I could still use the tree to minimize my intrusion on the scene. 
  

The bird seemed unperturbed by my presence and continued to work on the snag. 


It was pecking around the edge of a hole through the bark. 
  

Periodically, it would look around before going back to work. 
  

It would remove debris from around the edge of the hole and drop it on the ground. 
  

After working around the margin of the hole, it would almost disappear into the hole, and… 


remove more debris from deep within the hole. 
  

Again, it would look around before repeating the whole process repeatedly. I assumed from its complete focus on its work that it was building a nest. 
  

When I returned on April 12th, I didn’t see any activity at the hole. 
  

I could also see another hole above the first hole from April 5th. 

So, my question is: Was it building a nest and abandoned this hole, or was it simply searching for food? I didn’t seen any sign of food gathering so I am still assuming that it was a nest building activity. Either way, it was interesting to watch this activity and I’m going to keep an eye on this snag to see if there’s any sign of nesting activity as time goes on.

Spring Is In The Air: Fort Yargo State Park, Section B To The Dam, April 5th


April 5th. When I visited Fort Yargo State Park in mid-February, there were few signs of Spring. The only wildflower plants that were obvious were the leaves of Cranefly Orchids (Tipularia discolor) that I found in many places. On my previous walk on March 29th, trees were starting to leaf out but there wasn’t any sign of wildflowers. 


The route… I’ve described it here, here, here, and here. This walk doesn’t have the variety of wildflowers as my other walk from the Group A Shelter to the Old Fort but it does have some gems.


It’s useful, sometimes, to be able to lean against trees to steady oneself while taking photographs but now vines were leafing out and it was becoming more important to check out what you were going to brace against. In this instance, it would have been Poison Ivy (Toxicodendron radicans); three leaves. Not a good idea. 


Just down the trail Virginia Creeper (Parthenocissus quinquefolia), with five leaves, wouldn’t be a problem. 
  

More Christmas Ferns (Polystichum acrostichoides) were sending up fiddleheads.


Green growth was more obvious in the understory along the trail. 


Some Loblolly Pine (Pinus taeda) seedlings had popped up. Some were still wearing their seed coats.  


The Tulip Poplar (Liriodendron tulipifera), that only had one small leaf emerging a week previously, now had developed three leaves.


The Common Mullein (Verbascum thapsus) plants were thriving, almost double the size from the previous week. 


Deciduous trees along the shoreline were leafing out and the pollen had been blown form a thick scum in places. 


My favorite tree…


Now this was a surprise. A Perfoliate Bellwort (Uvularia perfoliata) plant in bloom. I’ve never seen one of these along this trail before. 


More Perfoliate Bellwort plants. I found about a dozen scattered in the woods behind the plant in bloom. A little further along the trail I found a large cluster of 30 to 40 plants. 
  

While I was looking at the Perfoliate Bellworts, I heard a soft tapping on a tree trunk. I tracked it down to this snag. 


It was a Brown-headed Nuthatch (Sitta pusilla) working on a hold in the tree trunk. 


A closer view. 


And finally, what I had actually been looking for. A Pink Lady’s Slipper (Cypripedium acaule) poking its leaves up out the leaf litter. I had remembered that there were about 20 plants on this hillside. I photographed them originally late one afternoon in 2011. I could never remember exactly where they were, other than that they were on a hillside. 


I wandered around and found more plants, and then… 


there’s always one precocious plant. And here it was. It had already set a bud. 


Another cute Loblolly Pine seedling with its seed coat still attached. There were a lot of these, as well as seedlings that had already popped the seed coat. 


The trail back down ‘The Hill.’ 


There were just a few Common Blue (Viola sororia) Violets were blooming near the bottom of The Hill. 


The Cranefly Orchid leaves were still visible but harder to find now that plants were growing up around them. 
  

More Christmas Fern fiddleheads. 


I've been watching these Cranefly Orchid leaves because they are easy to find. They are looking less healthy every time I see them. Soon they’ll be gone. 


On my way back over the bridge to the parking lot, I caught a glimpse of pink along the shore west of the bridge. A rhododendron in bloom. 


I’ve always identified these as the Mountain Azalea (Rhododendron canescens), also called the Piedmont Azalea or Florida Pinxter Azalea. There’s another rhododendron, the Pink Azalea, also called the Pinxter Flower (Rhododendron periclymenoides). I’ve never really been sure which is which. According to the folks at the Hilton Pond Center for Piedmont Natural History in York, South Carolina, these species may be differentiated by whether the flower tube is sticky (R. canescens) or not (R. periclymenoides). They describe R. periclymenoides as having a light fragrance. R. canescens is described by Floridata as being fragrant. Since the flowers on this shrub were hanging out over the water, I was going to have to wait until some of the plants along the trails flowered before I could satisfy my curiosity about this identification.

All in all, this was a rewarding walk; the discovery of a Perfoliate Bellwort on this trail as well as the impending blooming of the Pink Lady’s Slipper Orchids.

At The Feeders: Brown-headed Nuthatch (Sitta pusilla)


March 23rd, 2014. We installed a tube feeders (one with mixed seed and one with sunflower seed), a platform feeder and two log feeders in mid-December, 2013.

We saw the first Brown-headed Nuthatch (Sitta pusalla) on January 22nd this year and feeds only at the tube feeder filled only with sunflower seeds. It may have been coming earlier but usually doesn’t spend much time at the feeder unless there are few birds at that feeder. I’ve read reports of these nuthatches staying at a feeder unless they have to leave but ‘ours’ are quite shy and leave at the slightest disturbance.
 
It’s a small bird (3.9 to4.3 inches), small compared with the White-breasted Nuthatch (Sitta carolinensis) which is 5.1 to 5.5 inches long. 

Perched at the feeder. 

Fetching a seed. 

Seed in beak, deciding whether to eat in or leave. 

Perched on a nearby branch – a rare sight. I only saw a nuthatch perched on a branch near the feeders on one occasion. They usually grab a sunflower seed ‘to go’ but will ‘eat in’ if it’s quiet. A favorite spot to hull their seed is in the crook of a branch on a nearby pine tree.

We saw at least two Brown-headed Nuthatches this year. They are resident in this area and their distribution is limited to the Southeastern U.S.
