Carol, when you see all the hosps go take your feeder down
Brome makes a great feeder that has weight adjustable perches
mine are set to close the feed ports if more then one sparrow tries eating.
the rest have to pick up the scraps off the ground.
I set the alarm to go off an hour before sunset
when most hosps are roosting
add a cup of seeds to the platform tray
and Viola, cardinals show up :)
