Perch for bucket port that allows for desirable song birds to eat in comfort. Available on Mandarin Bird Feeders (AR150/152) only. If your bird feeder has 4 ports & 4 perches then this is the correct replacement part.
(If your bird feeder does not have 4 ports & 4 perches, and instead, delivers seed through a tray at the base of the feeder, then your feeder is not a Mandarin bird feeder (AR150/152) and is a SkyCafe bird feeder (AR360/AR362). Go HERE to view SkyCafe replacement parts.)
