Heron

Yesterday’s top Berkeley bird: This great blue heron, which was hunting in the meadow near the off-leash dog area in Chavez Park near the Marina. The place is crawling with ground squirrels, and you see herons and egrets stalking them — or staking out their burrows, anyway — fairly frequently. Other people in the park have told me they’ve seen a heron catch a squirrel — spear it, then swallow it whole. That’s what this one did as we passed yesterday, though I didn’t actually see the spearing part. It tossed its catch into the air and caught it, then took several minutes to work it down. I don’t think it was keen on flying while it was trying to swallow such a big lump of protein, and I was able to approach to about 30 feet with my non-telephoto-equipped digital camera for this shot.

Nature vs. Nitwit

Over the last few weeks, Scout (a.k.a. The Dog) seems to have become obsessed with ground squirrels that apparently infest Chavez Park, the place we take him to run. He’ll stop near a fresh burrow and give it the once over; every once in a while, he’ll dive nose first into one and start digging furiously. So far as we can tell, he’s never come close to catching anything; most of the time I figure the squirrels are looking out from some other entrance to their burrows and having a good laugh.

But maybe not.

The other day, we saw a great blue heron in the meadow we cross on our way to the off-leash area. Scout was so fixated on squirrel world that even when we were within 100 feet of the bird, which stood about 30 or 36 inches tall, he was oblivious to it. We gave it a wide berth, in any case. When we came back about 40 minutes later, it was still there, though it had moved about 100 yards or so across the grass. It wasn’t until I stopped and watched that I realized it, too, was hunting whatever is in those burrows (Scout still was paying no attention, though I put him on the leash so he wouldn’t go charging after the heron once he spotted it). It struck twice while I watched, plunging its beak into the burrow holes, but it came up with nothing.

After a while, a couple stopped and watched what was going on. The guy said he’d seen herons catch squirrels in the field–impale them on their beaks, then sort of toss them up and swallow them. “A couple of times I’ve seen herons out their with their beaks completely red with blood.” I think the herons have a couple advantages over Scout and his like: they’re stealthier, they strike suddenly, and if they hit their target, there’s no fight.

Not sure if the bird above is the same one we saw the other day or not (didn’t have my camera with me then). It was in the same place, anyway (for a local reference in the picture: that big white building that appears above the telephone pole in the middle distance is the Claremont Hotel, which is probably three miles in a straight line from where we were; the high point in the hills beyond is Vollmer Peak Round Top, about 1,900 1,760 feet above sea level and about six eight miles away).
