This bird feeder has been designed to hold a block of suet cake, that can be either purchased, or made at home, using suet, and a mix of meal worms, seeds and nuts. It is durable and made from plastic coated wire, and has a chain, so it can easily be hung from tree branches, metal frame bird feeding stations and bird tables. Suet cakes are an ideal winter feed but are also suitable for all year round feeding. Refilling is easy; simply open the cage at the top. Specifications Dimensions: L12.5 x W4 x H12cm Weight: 100g
