Autumn perch


Chestnut-backed Chickadee (Poecile rufescens) in our backyard in Cotati on 20 November 2017.  (It's nice to be back!)

Back in the bay

A couple of birds seen in Upper Newport Bay on 16 November 2017:


American Wigeon (Anas americana)


And one for the record:


I'm not sure how common Lapland Longspurs (Calcarius lapponicus) are in Orange County.  This bird was feeding along the edge of a salt marsh below the Upper Newport Bay Interpretive Center.

The violinist of the Pacific

When I heard we would be at a meeting near Newport Bay, I wondered if we'd have a chance at seeing a fiddler crab.  There's only one species of fiddler crab in California, and I vaguely remembered that its northern range limit is near Newport Bay.  (They are now found as far north as Santa Barbara.)

We took a drive along the shore of Upper Newport Bay and stopped to check the upper edges of the marsh.  It didn't take long to spot them!  Meet the Crenulated Fiddler Crab (Leptuca crenulata):



Here's another male with its burrow nearby:



And a female, with two smaller claws (instead of one larger and one smaller claw):



Later, when reviewing photos, I also spotted a few juvenile fiddler crabs.  Can you find the juveniles in the picture below?  (Hint: They're near their small burrows.)

   

There are two juveniles in the picturesee yellow arrows below:


P.S.  When I was reviewing the common name of this species, I encountered several versions — e.g., Mexican Fiddler Crab, California Fiddler Crab, Crenulated Fiddler Crab.  Because the geographic range spans both (Southern) California and Mexico, it was hard for me to justify using either of those names.  It's always helpful when the common name is linked to something in the scientific name, so I used Crenulated Fiddler Crab in this post.  "Crenulated" means having an irregular, e.g., notched or scalloped, outline.  

I also encountered an alternative Spanish name for this speciesCangrejo violinista del Pacifico.  I think that translates into "Violinist crab of the Pacific."  The "violinist" portion refers to the movement of the male's large claw during courtship.

Waving hello from SoCal

We're at a meeting in Southern California, but before the meeting started we took a quick walk on Newport Beach.  Here are a few quick wave shots taken on 16 November 2017.

Orange ears

Okay, maybe we just haven't lived in Cotati long enough, but this morning was the first time we've seen a squirrel in our yard.  I managed to take a few quick photos to document it before we left for work.


Eric looked out the window early this morning to see an Eastern Fox Squirrel (Sciurus niger) walking along the fence and climbing up a nearby tree. 

At first, the orange coloration below made us think about Douglas' Squirrel (Tamiasciurus douglasii), but this squirrel was larger.  And later when reviewing the identification, I noticed the orange ears, bushy tail, and lack of black line between the gray on the back and the orange belowcharacters which led to Eastern Fox Squirrel.


Since I'm relatively new to California, I don't know the entire story of how Eastern Fox Squirrels made it to the West Coast.  I hear they were introduced to the Los Angeles area in the early 1900s, and possibly to San Francisco in the late 1800s.  

P.S.  If you're interested in comparing squirrel species, review the post from 4 December 2012 to see some photos of a Douglas' Squirrel in Sebastopol.

Rocky, Part 2

Lots of chores today, so here are two more images of the Rock Sandpiper on Bodega Head during the winter of 2012-2013.  That year, the Rock Sandpiper stayed around until early March.



A comparison with Surfbirds:
