One morning last week, my sweetie and i were sitting outdoors in the hot tub when a nuthatch lands on our board-and-batten sided house. He pecks at the siding a few times.
Odd, i thought. Is he looking for bugs, as the woodpeckers do? In this cold weather?
Then he extracts a sunflower seed from between a batten and a board.
Aha! He uses our house to "bank" his seeds, so that when he's hungry, he can make a withdrawal from his savings account.
Now when i hear a light tap-tap-tap (3 taps) on the side of our house, i smile because i know the nuthatch is making a deposit into or a withdrawal from his seed-savings account.
