egret

 

These don't look so 'little' to me, but the translation is "little egret" which weighs about 310 g, or almost 11 oz.  I rather like the rhyming scientific name.  Above is  the Reddish Egret (700-850 g or 25-30 oz), which is far better displayed on a souvenir sheet than just the stamp.  The $5 in Eastern Caribbean Dollars is equal to 1.58 euros, 1.38 pound sterling, 1.85 USD, and 2.54 CAD

Audubon's depiction of these egrets was made 1827-38.
