The term 'Leggy Bird' is a general term used to describe three species of birds: the EGRET, WADER, and HERON. The EGRET is a white bird with long legs and a long neck, while the WADER is a long-legged shorebird that feeds in shallow water. The HERON is a large, long-legged bird that typically inhabits wetlands. All three species are known for their long legs, which is why they are collectively referred to as Leggy Birds.
