**link to part 2:zimmer-creek-road-la-salle-parish-2017 pt 2
Though I have birded this location a few times before this year, I've largely neglected it. This is a shame, because it's a nice example of typical habitats found in the upland part of La Salle Parish, and unlike many roads in the woods around here, this one is in pretty decent condition, and though not gated/posted it has large stretches without houses, giving one opportunities to bird from the road without being intrusive. The route taken on all of the visits covered in this blog entry includes the roughly 0.75 mile of Fount Cutoff Road between hwy 127 and Zimmer Creek Road, and then the part of Zimmer Creek Road from there south to the southern end at Highway 84. The odometer usually shows 5 miles total by the end of the route. The general terrain is hilly, specifically in the northern 3/4 of the route, and pine plantation in various stages of growth, from one-year-old cutover to medium-age pines (guessing 20+ years old?), dominates. There are almost no real pine woods left, though, by which I mean mature pine forest. The route crosses a few small creeks, providing some instances of hardwood creek bottom woods (with some mature pine mixed in), especially at the first two bridges encountered when doing the route from north to south as described. I THINK the second one -- the largest -- is the namesake Zimmer Creek. These streams are all tributaries of Bayou Funny Louis, a large creek that flows from northeast to southwest, passing just north of the route.
There are a few houses along the route, but most are clustered near the southern end so there are, as I mentioned, long stretches where one can stop and be comfortably distant from human habitation. The presence of some human habitation does however attract some species that might otherwise be missing along the route, including Barn Swallow and Purple Martin, Northern Mockingbird, and the herons and egrets attracted to man-made ponds.

| Fount Cutoff Rd -- The bent trees are from the April tornado, which crossed this road. It caused considerable damage just a little ways further along its path, in the Summerville community, but the damage was relatively light here. |

| second creek crossing -- the Louisiana Waterthrush spot |
 |
| The woods around the creek and extending a little ways south to the highline are the main "big woods" along this route. Logging operation heard further upstream from here on 6/29, but pretty close and visible up the high-line on 7/6. |

| Louisiana Waterthrush -- 4/17/17 |
Cedar Waxing, which are still common in this area well into May, was the only "winter bird" species encountered. All others on this list are presumed to breed in the vicinity of the route, with the probable exception of the Great Blue Heron and Great Egret.
In the list below, I give special attention to the 10 wood warbler species (including Yellow-breasted Chat) that were encountered; listing numbers of individuals and dates of observations for each of those species, and supplying additional comments for some, as well as photos and video.

(video below: Two of the sweetest sounds in nature -- songs of Wood Thrush and Swainson's Warbler. Video taken 6/17 at Fount Cutoff Rd. *edit: I hear Eastern Towhee in there, too.)
Brown Thrasher
Northern Mockingbird
Cedar Waxwing (15 on April 17)
Worm-eating Warbler -- April 17 - 2 (singing), June 17 - 1 (singing), July 6 - 1 (heard and seen at same spot as previous)
(Heard in the video below are Swainson's, Worm-eating, and Kentucky Warblers, and Northern Cardinal. Vid. taken 6/17 along Zimmer Creek Road. Hooded and Pine Warblers were also singing across the road at that spot, but I don't hear them in the video.)
Louisiana Waterthrush -- April 17 - 3 (one pair heard and seen; one at another stream heard singing), June 17 - 1 (singing, same spot first encountered on 4/7), June 18 - 1 (singing, same spot as previous)
When I arrived at the promising-looking patch of Louisiana Waterthrush habitat on my first visit this spring, I didn't hear LAWA singing. I don't like to overuse playback, but I decided to play LAWA song to see if I could get a response, because surely the species was present at this spot. Immediately got a response, and leaving it playing a little while, I got good looks of one and heard it's mate calling a few times from just upstream. In the video below, I was recording his calls after ending playback, when he flew into frame.
Here's a video from 6/18 where the LAWA can be heard singing a couple of times.
On 7/6 I didn't hear Louisiana Waterthrush for certain at usual spot, but might have heard call a couple of times. However, the noise from a logging operation nearby made it hard to hear bird vocals in those woods.
Black-and-white Warbler -- April 17 - 5 (singing). Missing from other dates. Had they simply hushed their singing by that point in the season?
Swainson's Warbler -- April 17 - 5 (four singing, one calling and briefly seen), June 17 - 7 (all singing, one also seen), June 18 - 2 (singing), June 29 - 1 (singing), July 6 - 2 (singing)
I have a special affinity for Swainson's Warblers -- they're just naturally a favorite of mine and I make a point to seek this species out when in appropriate habitat and try to keep track of exactly where each was found from visit to visit and from year to year.
The Swainson's in these photos is the same one heard singing w/ W-E and KY Warblers in the video under the Worm-eating Warbler account.

Prairie Warbler -- April 17 - 10 (all singing, two seen), June 17 - 2 (singing), June 18 - 2 (singing), June 29 - 2 (A female was seen bringing food to nest and one young nestling was briefly visible sticking it's head up when she approached nest. Any other young in nest were hidden by foliage. The nest was roughly 8-10 feet up in a Sweet Gum sapling. On 7/6 I staked out the nest for a couple of minutes but saw no Prairie Warblers.)

Redfin Shiner, Longear Sunfish -- Both fish species were visible from the road, in the largest creek, which appears to be spring water. One pair of the sunfish were observed spawning on June 18 and four males, each guarding a nest, were observed on June 29. Some males noted at nests on July 6. The Redfin Shiners were swimming around the nests on all three dates, especially active on 6/18. I've read that this shiner species apparently spawns over the nests of sunfishes (source: "Texas Freshwater Fishes" website - http://txstate.fishesoftexas.org/lythrurus%20umbratilis.htm), so perhaps this is what was going on. Videos below...

(Also, because this is such an extensive subject, and practically each visit to the field seems to yield something that's new to me, I'd like to do a series of posts dedicated to wildflowers from the various locations I visit. Perhaps I'll start that later this summer. But for now, my Zimmer Creek Road list...)

 | ||
| Blue Waterleaf (probably Hydrolea ovata, right?), 7/6. Other common names of H. ovata include False Fiddleleaf and Hairy Waterleaf. Hydrolea are some of my favorite flowers to find. There were a good many of these in bloom on 7/6 in a wet patch in a small cutover at the edge of the first little hardwood creek bottom. |
 |
| Finally found on this route on July 6 (despite being common in this terrain in this region, w/ blooming starting back in the spring)! Common names of Asclepias tuberosa include Orange Milkweed, Butterfly Milkweed, Indian Paintbrush. |
*Hypericum species:
(The websites linked at beginning of wildflower section are the sources for much of the info below.)
There are a number of similar-looking species of Hypericum (the various "St. Johnswort" and "St. Andrew's Cross", and similar species). As I said, I'm teaching myself wildflower i.d., and I'm finding that these are especially tricky. I think there are 4, possibly more, species of Hypericum represented in photos from this location. So, here's a breakdown of what I think we have here...
Hypericum with 4-petaled flower -- St. Peter's Wort, St. Andrew's Cross, or Pineland St. Johnswort?
St. Andrew's Cross are named for the four petals in an 'X' shape. There's a St. Andrew's Cross with narrower petals and a more distinctive 'X' shape (H. hypericoides) that I've seen at other locations, but I hadn't noticed ones with wider petals before, like the flower in the photos below. Maybe it's the same species, maybe it's St. Peter's Wort (H. crux-andreae). Yeah, the one w/ the Latin name meaning something like "Andrew's cross" is the one called St. Peter's Wort... because "reasons", I guess. A third option, Pineland St. Johnwort (H. suffruticosum) might have to be ruled out because our plant is presumably too tall (over 6 inches). Pictures below...
 |
| A 4-petaled Hypericum -- could it be H. crux-andreae or H. hypericoides or H. suffruticosum ? Whole plant pictured below. Photo taken - 6/29 |
 |
| Whole plant (detail above) |
 |
| another 4-petal Hypericum -- photo 6/29 |
 |
| What I think is Orangegrass (Hypericum gentianoides). Photo -- 6/29 |
These are two more St. Johnswort. Initially I was pretty confident that the first species pictured below was Coastal Plain St. Johnswort (H. brachyphyllum), but I'm not certain....
 |
| I believe these may be H. brachyphyllum. ZC Rd, 6/18. They have been abundant along Fount Road and northern part of ZC Rd since my 6/17 visit. |
 |
| more possible Hypericum brachyphyllum along Fount Rd, showing full plant |
 |
| Larger 5-petaled Hypericum -- ZC Rd, 6/29 |
All just guesses, really. I'd like to explore this further in the planned wildflower posts, by which time I'd hopefully have more information, and possibly additional species, better photos, etc.
