A system for creating a plurality of sheltered stalls around feeding ports of a hummingbird feeder. The sheltered stalls may be formed by generally V-shaped members having opposed curved wings, one stall being formed beneath abutting wings of two abutting generally V-shaped members. The generally V-shaped members may be supported on mounting hooks which are either integral with or removable from the hummingbird feeder. The sheltered stalls and mounting hooks are red. The system may include the hummingbird feeder. The system deters dominant males from preventing use of the hummingbird feeder by competing hummingbirds.
