Re: Heron and Grasshopper
In that case i would go for Great White Egret, as the other contender being a Cattle Egret, but that is small as well. The crests are a breeding season feature.
The Greats have yellow bills but can show black bills depending on age and breeding condition.
A photo of a Little Egret alongside a Grey Heron i took a few years back showing how small they are.
