Kinney tree swallow bird houses are designed to speed young bird feeding and to provide maximum protection against rain and cold. They permit parent birds to feed their fledglings without entering the box. Preferably mounted in the open, along borders of pastures, meadows, swamplands, or ponds where an abundance of flying insects exist. Position by April on a post 6 to 15 feet high and away from shade trees. Only 4 available. Hand made wood. See photos. $20 each or take all 4 for $60. Reply with name and phone number please.
