Egret comparison

An initial comparison of 4 similar species of white egret:

Snowy Egret: Bright yellow lores - dark bill
Little Egret: Greyish yellow lores - dark bill
Great Egret (egretta & alba): Green grey lores - yellow bill
Cattle Egret: Yellow lores - short yellow bill - hairy under bill

Snowy v Little: Yellow lores (and feet) on Snowy
Cattle v Little or Snowy: Short yellow bill on Cattle
Little v Great: Yellow bill on Great (can change)

Later I will include a comparison of size, legs, plumage and feet, different ages and breeding seasons, and location
