Someone posted years ago here about feeding crows in a local park that they rode by daily on their bike, and how for months after they stopped feeding them they were occasionally met by a phalanx of crows who flew alongside them for a while as they rode.
That has been on my bucket list ever since. Not a whole phalanx, but I would like to have a crow friend like Patera Silk did. They migrate through my area in midwinter, so I will have to get some unsalted nuts this year (and the next, and the one after that…)
