Soon to be jellies?

Orange moustache
This is Phidiana hiltoni at Pinnacle Gulch. We're still tracking where and when this more southern species shows up in Sonoma County, so if you happen to see any, let us know!
(Refer to the post "A new home for Hilton's" back in 2015.)

Settling into summer
A nice trio of barnacle species on a mussel shell:
- two Thatched Barnacles (Semibalanus cariosus), the ones with the ribbed look, at the bottom and upper left
- two Acorn Barnacles (Balanus glandula), the ones with the smoother look (center and upper right)
- seven Little Brown Barnacles (Chthamalus dalli), the smaller ones with a brownish gray coloration, four at the upper left, one between the upper two whiter barnacles, and two on the right side.
(There are also some very tiny barnacles growing on the other other barnacles, but I'm just pointing out the larger barnacles for now.)
It's been a good spring for settlement of juvenile barnacles. Now we'll see what the summer brings!
Happy Summer Solstice!

Two skimmers skimming
A few more photos of two Black Skimmers (Rynchops niger) in Bodega Harbor yesterday (10 June 2023). Although a small number of Black Skimmers nest in south San Francisco Bay, they are more common in southern California, so it was fun to spend a few minutes with them.
Most of the images I have show the skimmers skimming. This is a highly specialized feeding technique — dropping the lower mandible into the water while in flight, hoping to make contact with a fish.
First, here's a photo where you can see the difference in length between the upper and lower mandibles:

Running out of time tonight, but here's a quick photo of a Black Skimmer (Rynchops niger) in Bodega Harbor on 10 June 2023. [You can click on the images for larger versions.] I'll share more about them tomorrow!

Mottled
Whew, we've had a busy week of field work during early morning low tides. At the end of our surveys today in Mendocino County, Eric photographed this wonderful Six-armed Sea Star (Leptasterias sp.). Thanks, Eric!

Morning owl
We were getting ready for early morning field work today (7 June 2023) when Sam noticed a large bird swooping across the field nearby. We had great looks at this Barred Owl (Strix varia) before we left the area.
Thanks for the sharp eyes today, Sam!
