Our Feeder Seed is a good general purpose food formulated specifically for clinging bird species and primarily for use in tubular seed feeders. It is an economical food to start feeding your garden birds. This mix is free flowing in nature which prevents clogging. \"The birds absolutely love this seed mix- the small birds queue in the hedge next to the feeder taking turns to collect some food, and a pheasant stands underneath to catch any falling seeds!\" Review via Reevoo from Caroline, GB, January 2020
