Its year-round entertainment to watch what they do

That is an understatement :)

We have one bird bath, a big one. Are yours different sizes? Our is next to a tuckeroo. The tuckeroo grew over the bath such that now by chance there is a big bough over the bath a foot and a half above the water. Often, birds will jump off the bough into the water, have a splish, jump up to the bough, have a shake, then do it all again.

except ours is taller/older and the lower boughs are much more massive than the ones in this tree. edit: oh yes our trunk is much wider than this one, double perhaps

Yes maggies are so intelligent. Such characters.
