Boreal chorus frongs are the smallest frogs in B.C. (less than 4 centimetres long). They can be any colour (olive, grey, brown, green, red) and are characterized by a solid dark stripe from their nose to the base of their legs. Theyalso have three dark and sometimes broken stripes on their back.
Range & Habitat
These frogs live in moist grassy or forested areas near wetlands across North America, but in B.C. they only live in the far north-east corner of the province.
Diet & Behaviour
Northern chorus frogs like to eat ground-dwelling invertebrates (insects) and often wait for their dinner to come to them.
Lifecycle & Threats
When they emerge from hibernation in early spring, the males earn their ‘chorus frog’ name by singing loudly to attract a female, and together they deposit jellied clusters of 30 to 75 fertilized eggs. The females can produce from 150 to 1500 eggs each spring! In B.C., loss of habitat to development is the greatest threat to these frogs.
