Herons, Kingfisher, Kinglets ...
0900 on the last Saturday of the month is the Llano Estacado Audubon Society bird walk, often held at Lubbock Lake Landmark. [Check the LEAS page on Facebook to see where they will meet.]
On the last Saturday in October, 2018, Yellow-crowned Night Herons were seen along with a Belted Kingfisher at the dig site, but in the trees near the entrance to the visitor's center there were a couple of Ruby-Crowned Kinglets and a Vireo.
Don't assume that birds are not to be found close to the building!
And of course out on the short grass range there are sparrows. My last sparrow sighting there was a Savannah.
