Another Sunday, another walk with Olga on Hampstead Heath. I felt a strong need to get out in some fresh air, away from the news and my own dread. And it worked. We had a terrific walk and saw some interesting stuff.
Someone (or something?) turned this notch in the branches of a tree into a perfect cup for acorns.
This musk mallow provided a burst of purple color in an otherwise dry, brownish field.
Along one path I saw dozens of ground-nesting bees -- at least, I think they're bees -- popping in and out of little holes. They each seemed to have a hole to themselves, rather than all living together in a single hive, so I think they're solitary or mining bees. They didn't seem threatening. Can you see this one in flight, and the several holes in the soil at right?
Anyway, it was a good walk. Someone had a lot of fun.
I took some more water down to the once-viney tree, but I also did some reading about crabapples, and supposedly they're tough, drought-tolerant trees that thrive in full sun. So I can't imagine any reason why this one, an established tree that's been there for several years, would be dying. There are some fungi that can cause crabapples to lose their leaves, but they don't kill the tree -- and of course autumn is approaching, so maybe the tree's yellowing is just seasonal change. That's what Dave keeps saying: "I think it's just fall!"
We've had a few more Covid cases pop up among our students at school. So there are several large groups of kids and teachers who are all at home, self-isolating for two weeks. Maybe this is how the school year is going to go -- with revolving groups of kids and faculty out at any given time.
