A little bird just pecked my window 😯

We had a record heat wave along with a drought and I kept a deep clay saucer on a plant stand filled with water for them. It was near the window of the window next to where my computer desk was. One day I was on the computer and heard a pecking sound and it was a sparrow. I looked out and the water dish was empty so I refilled it for them. They did it more than once and the squirrel even started jumping up on the window screen and bumping to let me know he needed water too.
