West Bouldin Creek and Hornsby Bend (Jan 11, 2018)
My first real, normal trip around Austin in 2017! This is discounting the Pace Bend/Commons Ford trip I made on the 3rd because that was a deliberate part of the Big Week. Today I started off (a bit late) at West Bouldin Creek, then made stops at the Peninsula Trail, Hornsby, and Lake Pflugerville.
West Bouldin Creek Greenbelt
My first time at this site! I came because there had been a number of fairly consistent-seeming recent reports of Winter Wrens (Troglodytes hiemalis), and I wanted to make sure I found one before the end of winter this year (I missed this species in 2017, probably mostly for lack of an effort to find one). I didn’t end up finding this bird, maybe because I didn’t actually get here until about 9:45, but it was still a pleasant morning and a good reconnaissance visit to a new site! I think this place is probably worth a repeat trip at some point.
It’s mostly the typical Travis County greenbelt habitat with mixed Live and Spanish Oak (Quercus fusiformis and Q. buckleyi) / Cedar Elm (Ulmus crassifolia) / Juniper (Juniperus ashei and J. virginiana) woodlands, with a good amount of fairly thick understory which seems reasonable for the wrens I came looking for.
While I didn’t find the wren, I did find new year birds in White-eyed Vireo (Vireo griseus) and several Hermit Thrushes (Catharus guttatus)!
Hornsby Bend
Just drove around the ponds today and literally never got out of the car - as well as just checking out the water birds I was also trying out a new camera for more or less the first time! Had a reasonable amount of success in general, although at this point I hadn’t yet figured out how to mess with any of the exposure-related parameters so a lot of my photos of ducks against bright water didn’t come out too well. Others (including those included here) I was mostly happy with, though!
The waters were a little quiet today, and so I actually made deliberate counts of all the birds, including the Northern Shovelers (Spatula clypeata) which I usually just estimate to the nearest twenty or so - today I had 174. I also saw several pretty interesting birds - the first was an Egyptian Goose (Alopochen aegyptiaca) right on the first dirt road to the north of P1E. This is an introduced species which I occasionally see feral at urban parks (Pace Bend comes to mind) around Austin, but which I’ve never seen at Hornsby before. The hackberries along the south end of P2 produced a Golden-crowned Kinglet (Regulus satrapa), which are really uncommon in Austin - but this is already my second in Travis County this year. I also had a Scissor-tailed Flycatcher (Tyrranus forficatus) on a little tree between the ponds when I was driving out! These birds are ubiquitous in Austin during the summer, but they almost all leave during the winter and this individual was flagged as an eBird rarity. We also had six STFL during our day on the Austin CBC a few weeks ago, though, so I wonder if these are more common in winter around here than I might have thought.
Lake Pflugerville
I came here in hopes of re-finding the American Bittern which was present here last January, although none had been reported yet this year. It was incredibly windy, though - upwards of 30mph - and I didn’t really see much of anything at all in the reeds, other than a single Marsh Wren (Cistothorus palustris). There were also a surprising number of water birds out on the lake despite the wind (and the multiple windsurfers) - mostly American Coots (Fulica americana) but also a number of grebes and ducks, including a dozen or so Canvasbacks (Aythya valisineria). Those aren’t common in most water bodies in Austin, but this lake is a pretty solid and consistent site for them.
Although I didn’t find a Bittern, I saw later on that one was reported by someone else at this location that very morning! And Arman also heard Virginia Rails (Rallus limicola) vocalizing (another repeat bird from last year) - so I imagine I’ll definitely have to be back, probably earlier in the day and with less wind.
