A sparrow tried to take up residence in my v3 equipped bluebird house. Blasted the siren, which had to be deafening inside a small box. Didn’t faze the bird at all. Had to open the birdhouse and clean out the nest.
Had some crows totally decimate the sunflower seed tray. Have a WOC pointed at the tray to monitor the seed, because the squirrels make me put the tray on a 10 foot pole.
They jump high when popped with a 22 caliber CO2 pistol
