By far the best solution to the feeding of birds

In various books, these columns are recommended. Best solution, since no bird droppings, chickadees usually take a grain fly away and the next
come. Always clean everything very easy and convenient to refill.

As an observer, constantly there are new birds in these columns, see if
the column is empty, as opposed to bird feeders where one is not white
it still feed or there are empty shells.
