This bird feeder is very suitable for all birds that are no bigger than sparrows or the like -. Blackbirds, jays and magpies etc.haben no way to get to the food. The see-through feeding column is very well protected by two roofs that fill completely unproblematic. The feed can be composed of four holes that are located at the bottom of the column, are removed or out of the drip tray. This means that the birds get along well, which usually glean their food from the ground. These Bird Feeder I can therefore wholeheartedly recommend, even if you deeper must engage in the wallet a bit.
