2021 Merced County Species-to-Date (as of last checklist)
Life List = 183

Seeing a break between storms, I reached out to Rich Brown and Dale Swanberg to see if they wanted to explore the San Luis Reservoir State Recreation areas. I was hoping that something unusual would show up with the unsettled weather and strong winds the day before. We met up in Santa Nella and Dale lead us to Los Banos Creek Reservoir which is a part of the recreation area that I had never visited before. I noticed a couple of new year birds that went unrecorded for the time being as I’m sure I will get them at an actual birding hotspot later (Great-tailed Grackle and Yellow-billed Magpie).
25 Jan 2021 – FIRST STOP LOS BANOS CREEK RESERVOIR
At the bridge over the Delta Mendota Canal, both Rich and I stopped to quickly photograph a female Canvasback that was swimming away.
We quickly caught up with Dale, who was wondering what we were doing. The entrance seemed to be lacking the usual entrance sign that most state recreation areas have. There was a sign at the base of the dam though.
After getting our parking spot assignment, we parked near the entrance, searching for roadrunners that might be hanging out. We dipped on the beep-beep, but had an encounter with a very large pig and about 20 little porkers running behind her. The skies portended inclement weather and the water was choppy.
I was amazed at the number of Aechmophorus grebes hanging out around all coves and inlets of the reservoir. Aechmophorus refers to the genus name of Western and Clark’s Grebes that used to be conspecific until their split back in the late 80s. A quick count using my telescope of the birds I could see gave me a total of a little over 300 birds with the ratio of Western to Clarks at about 10:1.
For a comparison, Clark’s Grebes have an orangish-yellow tint to their bills and their eyes are entirely or mostly surrounded by white facial feathers.
The Western Grebe lacks the orangish tone in the yellow bill and their eyes are surrounded by black facial feathers.
On the way out as we were fording the creek, off to our left was the big momma pig hiding quite effectively in the reeds.
SECOND STOP MEDEIROS AREA
The winds had picked up as we reached the boat launch area and the birds were scattered quite a ways from where we were. Dale and Rich (socially distanced of course), searched every corner for something unusual or new for the year.
As we skimmed over the rafts of Ruddy Ducks and American Coots, we could see distant Canvasbacks, Buffleheads and Common Goldeneyes with nary a Barrow’s to be seen.
Up ahead something caught my eye. It was a small grebe, much smaller than either a Western or Clark’s and it had too distinctive of a white cheek patch to be an Eared Grebe. We pulled over, jumped out and got our binoculars on a nice Horned Grebe. This would be the first of this species to be recorded in the county this year. Horned Grebes are more of a coastal wetlands and bay bird with a few spotted in the valley each year. Not rare, but certainly uncommon.
After checking off the Horned grebe on our eBird Mobile checklist, we focused on the many Scaup flocks, hoping to ID a Greater in with the Lessers. Greater Scaup are similar to Horned Grebes in that they are more usually found along the coast. The one spot they seem easier to find though is exactly where we were.
The Greater Scaup is slightly larger, has a rounded head without any peak and a bill tooth that is relatively wide at the distal end of the bill.
We decided to give the other side of the reservoir a check to see if the winds were a little less knock your hat off.
THIRD STOP SAN LUIS CREEK AREA
We were treated to much calmer conditions at the San Luis Creek area and were treated to a flock of Lark Sparrows as soon as we started down the trail.
We enjoyed lots of Juncos and sparrows and some offshore Bufflehead as we walked along the shoreline. There were plenty of kinglets, sparrows and Bushtits, but nothing else unusual or new for the year.
On the way out a nice Common Raven posed for me.
