My Lifer Sabine's Gull. Also documented photographically, same time and place, by Greg Lasley:
https://www.inaturalist.org/observations/151433
Update (1/23/24): Scans of old Ektachrome slides added.

Sabine's Gull
juvenile
Hornsby Bend,
Austin, Texas
2 October 1978
images scanned from slides.

This record provided the 10th Texas record of Sabine's Gull, but now there must be 60 or more records of this species in Texas, mainly during the fall on inland lakes. A shot of the bird in flight is also posted showing the unique wing pattern of this species.

This Buckeye didn't have a cream colored band on the forewing. It also has more of a bluish sheen to the thorax and leading edge of the forewings. The spots on the forewing are darker on the inside. These are the reasons I believe this to be a Tropical Buckeye. I guess there is a chance that it could be a darker variety of the Common Buckeye.
I have seen some previous discussions on this from @greglasley

What do yall think?

Orange head with much more vivid, and darker, reddish-orange wing sheaths. Closely resemembles the specimen reported at https://www.inaturalist.org/observations/26660078. I believe this to be N. lurida and am submitting it to Bugguide.net.

Two different individuals documented here. Neither has a particularly obvious "white blotch" but the pattern of subterminal black marks and the buffy thorax seem to point to this species.

UPDATE (3/31/19): First individual (two images) re-IDed as Heterocampa subrotata and deleted here.

I only see this species here in Austin every other year or even less frequently, but the sightings are almost invariably in the first half of November. I assume this is a species that periodically migrates up from South Texas.

Argemone aurantiaca

One, or few, along main road.

Based on the orange latex, mentioned in the Flora of North Central Texas. The FNA does not mention latex color at all, and depends on various qualities of the surfaces of the leaves, stems and capsules, all of which were difficult to apply here. The leaf surfaces did not seem prickly or hispid between the veins, but they may have been minutely hispid (difficult to photograph). There were no capsules yet. The stems did seem somewhat densely prickley, but I don't know if that is distinguishing enough.

Geranium sp.

Went down to Goverment Canyon in hopes of looking for the Geranium texanum that was collected there listed in this record at the Plant Resources center (TEX00285228):
https://prc-symbiota.tacc.utexas.edu/collections/individual/index.php?occid=1197203&clid=0
I was hoping that I might find some Geranium plants in that area that have five purple anthers as I have observed in Williamson county in these observations:
https://www.inaturalist.org/observations/10653423
https://www.inaturalist.org/observations/10109163

The thought was that if I found the five purple anthered Geranium in a spot where Geranium texanum was collected that that might provide some more evidence that some of the floral characteristics (number and color of anthers specifically) of G. texanum might currently be incorrectly described in the current literature (currently documented to have 10 fertile stamens with yellowish anthers like G. carolinianum).

Unfortunately, the exact location listed in the herbarium record appeared to be off limits to the general public, but I was able to find two small populations of the five purple anthered geranium on the Recharge trail. The population documented here was probably about a mile from that location whereas another small patch on the Recharge trail was likely about half that.

Another interesting detail is that these photos show that though only five anthers seem to be well formed, there sometimes appear to be one or more smaller anthers that do not reach full size but which may or may not generate viable pollen.
