Mink, Otters, Birds (and a Cat)

It’s Fall again, a rewarding time to wander along the creek in Davis, California.   My most exciting sighting was an American Mink (Neogale vison) who emerged from the water and briefly struck a pose that showed off his hunting equipment.  American Minks, in the Mustelid (weasel) family, are native to Northern California but seldom seen.  Like River Otters (Lontra canadensis, another mustelid) and North American Beavers (Castor canadensis, a rodent), they are recovering after being nearly wiped out by water pollution and persecution. Two or three years ago I was astonished to see one.  Now they’re getting a bit more common, jostling with otters, egrets and herons in pursuit of fish and frogs.  This mink and a Great Egret (Ardea alba) were hunting in the same pool, and otters cruised nearby.

My main quarry were the colorful and elusive warblers passing through headed south, like this Townsend’s Warbler (Setophaga townsendi) and Wilson’s Warbler (Cardellina pusilla).

Some of these migrants will become meals for the Cooper’s Hawks (Accipiter cooperi) lurking by streamsides.

Many non-migratory songbirds like this Oak Titmouse (Baeolophus inornatus) are caching seeds for the winter.

My strangest sighting was a pair of Western Bluebirds (Sialia mexicana) acting like it was April.  Local experts told me these two could either be making a bizarrely late breeding attempt, or more likely, hanging around their nest box as a warm place to sleep.  Either way, it’s unusual behavior, since nests are normally deserted by fall.

Returning home from the creek, sitting down at the computer, it was all too easy to be distracted by more birds.  Our water feature and its overhanging Blue Elderberry (Sambucus mexicana) bush are popular in fall.

Red-Breasted Nuthatch (Sitta canadensis):

Black-Throated Gray Warbler (Setophaga nigrescens):

Bushtit (Psaltriparus minimus):

Boris and Natasha, my amiable home birdwatching companions, perfectly fit Jonathan Losos’ description of Ragdoll cats as “snuggly layabouts.”

    I suppose Rocky and Bullwinkle might be outdoors… one’s collecting acorns at the moment… Fearless Leader … not sure. Perhaps we’ll drop it.

    Delightful set, as usual (though I can’t comment every time).

  2. What delightful photos! I was exciting to see the mink photos.
    That Wilson’s Warbler is such a perfect pear shaped bird. I love that yellow and round black eye.
    Thank you for this set!

  3. Beautiful, and Thank You!

    When I was living in Giles Bounty in southwestern Virginia in the eighties, I was sitting on my deck one day reading when a mink and her cubs marched right in front of me heading for Sinking Creek (across the street). The minks were almost certainly feral refugees from a defunct mink farm. They were both bold and cute.

  4. Lovely photos! I’ve seen mink in the Sacramento River Delta on two occasions, though they were far apart. One in the region of Liberty Island and another, 10 years later, in Little Potato Slough off the San Joaquin River.
