Blossoming frog enthusiasts in New Brunswick will soon have a new tool to help them identify the province’s nine frog and toad species. Aided by a $2,700 grant from the Canadian Wildlife Federation, Nature NB is producing a poster and field guide to introduce beginners of all ages to their amphibious neighbours.
Green frogs are relatively large frogs, 6 - 9 cm in length. They can be distinguished from the similar bullfrog by the ridges that run down each side of their back.
To determine the sex of the green frog, look at its eardrum - if it is significantly larger than its eye it's a male, if it's the same size as its eye, it's a female. During the breeding season, you can also tell the males by their yellow throats.
The northern leopard frog is green or brown with dark, rounded, light-edged random spots, and a white belly that occasionally has a yellowish tinge. The body length of this species can exceed 10 centimetres but on average adults are usually five to nine centimetres long.
