One bird feeder includes by a three suckers (support plate 1 of 14A, 14B, 14C installation 2 on a glass pane (P)) figure. An entry table 2 is installed by the hook portion 7 in the lower part of support plate. Cutting out for U-shaped for minimum sucker 4 is arranged under the level of base portion 8 of entry table 2. The rear lateral portion for the triangular fin 13 being formed on the downside of base portion leans against on support plate in the region for cutting out 4 of U-shaped, it is ensured that tends to compress minimum sucker (14C) against glass pane in the weight of a bird in the forward position of entry table. In this way, the knocking-on of the array of the sucker from glass pane is prevented.
