With a wingspan of a little less than half a meter, great bigmouth (Oravis rex) is the largest of the agilifugiforms.  Bigmouths, with their large heads, heavy bills, and short wings (compared to other agiliforms) are a far cry from their more acrobatic cousins and prey upon grasshoppers and small vertebrates.  Found in southern North America and Central America, bigmouths are most common near streams and lakes, where their frog-like, croaking calls are difficult to ignore.
