I got up around 6:00 this morning with the dogs, fed them their breakfast, and then got myself ready to head out to the Effie Yeaw Nature Preserve. There were some specific trees I wanted to check for galls, but otherwise I was open to whatever nature wanted to show me.






I watched the Black Phoebes, which have a nest there every year, catch insects and feed their babies. A couple of times, I saw the adult do a kind of fast flip in mid-air and catch winged insects as they flew by. This year’s nest had FIVE babies in it, and they were all nearly fledged, so cramming them all into that little mud cup wasn’t easy. I could have watched them all day, but really needed to get moving.
I also got a glimpse of a Bewick’s Wren nesting cavity. There were three babies, again nearly fledged, sitting on the outside rim of the nest – which was well-hidden inside of a bush. Of course, as always, the camera decided to focus on the leaves in front of the nestlings, instead of on the birds themselves

There was a European Starling that was doing her wing-twirls, and another one that was poking its head out of its nesting cavity.
And I saw a few beautiful Ash-Throated Flycatchers.
I saw my first Tussock Moth caterpillar of the season, and my first Black-Tailed Bumble Bee on this walk along with several other insects. I’m trying to work my naturalist’s eye in anticipation of the upcoming City Nature Challenge.
I found a few Small-Flowered Catchfly flowers. They’re glandular-hairy especially on veins, and feel sticky to the touch.







It was fun seeing a mama California Ground Squirrel back at the burrow at the end of the trail on the bluff side of the preserve. She avoided me at first, but then seemed to realize I wasn’t a threat, and she came out and posed for me for a while. Ground squirrels are one of my favorite animals, so it’s always great to see them.


I walked for a whopping 4 hours before heading home. That’s the best I’ve done since my surgery in January. This was hike #22 in my #52HikeChallenge for the year.
