It took me some sleuthing to figure out where the actual type locality for this species was located. This species was described by Hershler (1995), and the type locality information provided was:
"Type locality: Unnamed spring about 4.8 km west-southwest of Hallelujah Junction, Long Valley, Lassen County, California, T. 22 N, R. 17 E, SW 1/4 sec. 9 (Figure 4E). Holotype, USNM 860642 (Figure 5E); paratypes, USNM 858262, collected by R. Hershler and D. Sada, 3 August 1990. Snails were commonly found on stones and in watercress of this large spring, which was situated adjacent to a residence and had been recently excavated."
"Remarks: This species is known only from the type locality in the southern end of the Honey Lake basin (Figure 6)."
The township and range described in the paper was wrong, as no springs matching the description provided were located there. However, using Google Earth I was able to identify a few possible spring candidates that could be the type locality approximately 4.8 km southwest of Hallelujah Junction. All of the springs that I thought could have been the type locality were located on private land owned by the City of Santa Clara. I obtained written permission to visit the property and quickly located the type locality spring behind the abandoned house on the property. Springsnails were not overly common in the spring, and the spring had been previously developed in the past. There was also evidence of use of the spring by cattle. I've attached two photos of the spring to this observation. I checked nearby springs to see if I could find springsnails, but I found no Pyrgulopsis in any other nearby springs.
The correct Township and Range for this spring and type locality would be: T. 22 N, R. 17 E, SE 1/4 sec. 17

Alameda Salt Marsh Song Sparrow (Melospiza melodia ssp. pusillula), photographed at Alviso Marsh in Alviso Marina County Park. Identiified as such from the bird's very heavy, dark streaking and its location in one of the South Bay's salt marshes.
Alviso Marina County Park is located in the Alviso district of San Jose, CA, in northern Santa Clara County. It is an excellent place to look for Alameda Salt Marsh Song Sparrow, as well as other salt marsh specialists.

This is a Common Black Hawk x California Red-shouldered Hawk. Not sure how to get this as the ID.
Known offspring of the Common Blackhawk that lived here for 15 years.

Leucistic? The pigment in the ocular orbitals is making me hesitate on saying albino

Red-winged Blackbird
near Stewardson, Illinois
1 June 1989
I'm posting this record just for the general interest of a Red-winged Blackbird with one white wing. Whether a partial albino, or a partial leucistic bird, I'm not sure. A local farmer told my wife and me that this bird had been on his farm for three summers. The bird left in the fall with the other Red-wingeds and came back in the spring. I watched it for about 30 minutes. It vocalized like any other Red-winged BB and interacted with other Red-wingeds normally. It was pretty flashy to see in flight, however. Three shots posted. These images scanned from old color slides.

In the peak of the top end dry season. A mantis crashed into the spotlight of my parked vehicle and fell on the ground, stunned. The katydid immediately arrived and began eating it. This is a dried up creek bed and the nearby vegetation is extremely dry - perhaps the katydid desperately needed the moisture. Bowerbird.org.au sighting being moved to iNaturalist as the former website is shutting down.

I'm pretty sure a hybrid but I'm not positive which two. I believe all four are now in this waterway. I was thinking M. chrysops x americana or M. chrysops x mississippiensis but I haven't been able to find any photos of these crosses for comparison.
