Distribution:
Boreal Chorus Frogs are found throughout most of central Canada, south through the northern Great Plains from extreme northwestern Indiana west to the eastern front range of the Rocky Mountains into parts of Idaho, Utah, New Mexico and Arizona. The southern edge of the range is a line extending from Colorado east to Illinois. In Nebraska this frog is statewide in distribution with only a few counties missing representative voucher specimens.

Natural History:
Boreal Chorus Frogs are versatile in their habitat choices. During breeding season they use nearly any body of water including roadside ditches, temporary playas in the middle of agriculture fields, buffalo wallows in grasslands, as well as other more traditional ponds and lakes. After the breeding season, they often can be found far from water in areas from open grasslands to dense woodlands. They will take cover beneath rocks and in crayfish burrows to avoid extreme climatic conditions. These little frogs are the first frogs to start calling each year often advertising for mates as soon as the snow melts, which is as early as the beginning of March in Nebraska. In most years their eggs have hatched before most other species have begun to breed. Males have exceptionally loud voices for their size, and a full chorus can be deafening. The song is similar to the sound of a finger running along the tips of the fine teeth of a comb. They usually call while clinging to vegetation along the edge of wetlands, calling both during day and night. Although they can be heard quite clearly, they are often hard to see. Eggs hatch quickly and metamorphosis is often complete by June.

Chorusing Phenology: The black outlined dots denote the Julian date (day of the year; 1 January = 1 to 31 December = 365) an observation was made. The thin red line depicts the range of dates between the beginning of the first, and end of the fourth quartile (excluding outliers; Tukey method). The thick light blue bar represents the second and third quartile (interquartile range; the middle 50% of all observations). Only one observation per Julian date is included in the graphs; so a date with multiple observations carries the same weight as a date with only one observation. The vertical bars correspond to the 12 months of the year; January through December.
