It's too hot to do anything except occasionally rotate to present the other side to the fan. Philadelphia peaked at 102°F (38.9°C) this afternoon. It's just after 6:00 now, and 101° in the city.
I put a 9"X13" pan of water out in the garden with ice in it in the shade this afternoon for the birds. I suspect neither bird nor beast spotted it, but the water is gone except for a teaspoon or so in the low end. Still no activity at the nest, but I haven't been watching it for more than ten minutes or so at a time.
When it gets closer to dusk I'll camp out on the deck and watch for as long as I can. Weatherunderground says it'll be going down to the low 70's tonight, so I'm hoping the deck will be tolerable for a bit.
They claim it isn't the heat, it's the humidity. Whoever "they" are, they are idiots. Today's humidity was 62%. So far as I'm concerned, I'll take 62°F at 102% humidity over 102°F and 62% humidity any time.
