Overhead

  

Stopping to pick up sandwiches in northern Sonoma County today and noticed a handful of Vaux's Swifts (Chaetura vauxi) flying overhead.  Photo for the record on 15 June 2025.

Left behind

  

I've realized I don't share scat photos very often, but here's an interesting one  an example of Harbor Seal (Phoca vitulina) scat.

A hat trick?

  

We were focused on other species while doing surveys along the coast in Mendocino County last weekend, but along the way Eric spotted several nice chitons.  Above, meet Tripoplax regularis.  (Also refer to the post called "The original sequins" on 26 February 2017.)

Below, this looks like a species of Mopalia, but we're not sure which one.  We wondered about Mopalia imporcata, a species we're not familiar with.  If anyone has thoughts about the identity of this chiton, we'd be interested!

 
 
And, one that was fun for us   a juvenile Katharina tunicata.  This individual was only ~1.5-2 cm long.  Katharina has become less common in the Bodega Bay area, so it's encouraging to see a young one starting out:
 
 
A wonderful trio, Eric!

Little one

  

A tiny Six-armed Sea Star (Leptasterias sp.) photographed in Mendocino County on 31 May 2025.  This juvenile sea star was only ~3-4 mm across from arm tip to arm tip.  

If you look carefully, you can see some of its tube feet extending away from its arms.  And the small red eye spots at the tips of the three arms in the foreground are also visible. 

Rather than releasing eggs into the water column, Leptasterias broods its embryos and the young sea stars crawl away from the adult.  Back in 2012, I shared photos of an adult Leptasterias with its brood of embryos and an image of an adult with many juveniles in the surrounding area (it's likely the juveniles recently crawled away from the adult).  To review those photos, check out the post called "Four brooders in one" on 29 February 2012.

P.S.  Thanks for the great photo, Eric!

Siblings

 
A couple of young Brush Rabbits (Sylvilagus bachmani) resting at the end of the day today (1 June 2025).  (There was a bit of a breeze ruffling the fur of the rabbit in the foreground.)
