Tricolored Herons measure from 56 to 76 cm (22 to 30 in) long and has a wingspan of 96 cm (38 in). They are not like the Great Blues. They might be more aggressive though.
I find more in the marshlands than swamps. This fall and winter there appears to be more than last year.
Most of the information states they breed further south, down in South and Central America. However I see many juveniles that look much too young to have come up north. Probably like many other species they are staying up here.
