The spring peeper (Pseudacris crucifer) is a small chorus frog widespread throughout the eastern United States and Canada. They are so called because of their chirping call that marks the beginning of spring. There are two subspecies: * The northern, P. c. crucifer, found all over the eastern USA and eastern Canada. * The southern, P. c. bartramiana. The southern is distinguished by a strong dark marking on its belly. P. c. bartramiana is found along the southern Gulf Coast from southeastern Texas to northern Florida and southern Georgia.
