Nalle Bunny Run 2019-11-16
Six people joined me on a cold Saturday morning, November 16, for the monthly group walk on Hill Country Conservancy's Nalle Bunny Run wildlife preserve. Despite clear conditions in other parts of Austin, the fog was thick early on the preserve. It thinned and finally became sunny during our walk from 9:00 AM until about 11:30. We observed 23 species of birds and here are some highlights.
In the cemetery as we listened to subtle calls of a few different songbirds, a strange honking started from across the fence. It turned out to be 5 Egyptian Geese that flew right over us. This exotic species seems to have established itself around Lake Austin, probably from escaped pets.
Down the hill on the sandy prairie habitat area we were lucky to get to watch a bunch of native sparrows foraging on the ground. Since sparrows specialize in looking for food on the ground, their plumage is cryptic and they are very wary of possible threats. Usually birders see sparrows when the birds are flushed off the ground and fly up to a nearby bush for safety. But these birds didn't seem to mind our presence, and we got to watch about 15 Chipping Sparrows and 5 Field Sparrows hop around looking for seeds in the low plants in the sand. Here's one of the Chipping Sparrows. See the dark line through the eye:
And here's one of the Field Sparrows. See its pink bill and white eye-ring::
As we watched them, a Sharp-shinned Hawk flew in and tried to catch one. We got to see how the sparrows reacted, flying into dense bushes nearby for safety. The hawk moved on and gradually we got to see the sparrows come back and resume their baseline foraging behavior.
Also over the sandy prairie we got to see a beautify Red-tailed hawk fly in and perch on a cypress tree. And a group of Double-crested Cormorants flew by in the distance, migrating south.
On our way back through the west half of the preserve we got to see a nice mix of songbirds including Yellow-rumped Warbler, Carolina Chickadee, Downy Woodpecker, and Red-bellied Woodpecker.
