The HummZinger® Mini has an 8oz capacitiy and 3 feeding ports.  The smaller capacitiy is ideal for using several feeders for territorial hummers who don't like to share.  The bright red cover attracts hummers from a distance and removes easily so the bowl can be cleaned quickly and thoroughly. All HummZingers feature a built-in ant-moat to block crawlingn insects and a brass rod to use for hanging.  The raised flower design diverts rain water from entering the feeder.  The Polycarbonate construction makes it extremely durable.  It has the Aspects Lifetime Guarantee.
