The Usual Suspects at Gristmill, 06-19-22

I got up around 5:30 this morning so I could get outside for a walk before the heat of the day came on. Walking in the summer is harder for me because I have to get up earlier to catch the few hours of comfortable temperatures… and going out early means I miss a lot of the insects that don’t come out until it gets warmer. Grrrr.

I went over to the Gristmill Recreation Area and didn’t see much of anything that I haven’t seen already.

The galls on the willows are getting more impressive and easier to see as the larvae inside of them grow. I did find one that didn’t look like others I’d previously seen. I don’t know yet if it’s a “new” gall or just an early iteration of a gall I’ve already seen. I’m not seeing any new galls on the oak trees yet.

I saw a few Black-tailed Jackrabbits around, and a couple of them let me take their pictures. No such luck with the California Ground Squirrels, though.

I watched a male Downy Woodpecker hanging around the hole to what I assumed was a nesting cavity. But I don’t think it was HIS nesting cavity. I saw a beak poke out toward him that looked “heavier” than a Downy beak would be… so I’m not sure what kind of bird was in there. I later saw the woodpecker going through the leaves of nearby trees collecting insects.

There were a lot of White-Breasted Nuthatches climbing the trees all around the trail looking for food. And I saw a Spotted Towhee stuffing its face with elderberries before flying away.

Elsewhere on the trail I found a Bewick’s Wren fledgling that was looking pretty rough, but that didn’t stop it from singing.

I walked for about three hours and then headed home. This was hike #36 in my #52HikeChallenge for the year.
