Parakeets, Canaries and Finches will be most comfortable on appropriately sized multi-branch bird perches. Our Multi-branched Manzanita Bird Perches offer much smaller diameters on some branches that will accomodate tiny feet. Often, some of the branches are in the 3/8" to 5/8" diameter range. Small birds love to flutter from branch to branch.  The multi-branch bird perch is great for aviaries.
