alerted by squeaking, I looked outside and got to watch a pair of flickers flirting! they were bobbing and flaring at each other, and doing little twirly dances. well, they were either flirting or fighting, and I *think* they were flirting, but idunno! either way, it was entertaining to watch.
also spotted a pair of pileated woodpeckers, but they flashed past too fast to know what they were up to. probably also either flirting or fighting--'tis the season.
