Sizing the feeder to the bird
The Mountain Bluebird measures 6.3–7.9 in and weighs 1.1 oz. Perches, ports and landing surfaces need to fit that frame — too small and the bird can't feed comfortably, too open and larger birds and squirrels dominate.
Keep it clean
Scrub feeders every two weeks in hot soapy water, soak 10 minutes in a 1:9 bleach solution, rinse and dry before refilling. Rake up hulls underneath.
