When I filled the bird bath the next morning, I filled it too full, even though there are some rocks in it, placed there for smaller birds. The water was too deep for this determined little wren, but that didn't stop him from taking his bath just the same.
Needless to say, after watching his efforts, in the future, when the bird bath is actually level (which is rare), I won't be filling it so full!
