Canadian Toad
Bufo hemiophrys
by Jeff
LeClere
Status
No status assigned in Minnesota.
Description
The Canadian toad may get up to 3 inches
in body length. It is very similar in appearance to the American
toad. Canadian toads are white or light brown with dark spots
scattered randomly about the back. These spots may be brown,
black, or even reddish and are outlined in white. Each spot
contains one to three warts. The belly is light colored and
has dark markings, especially on the chest. The thighs usually
have a yellowish wash. The cranial boss or "bump" located
between the eyes is the only consistent characteristic that
distiguishes is toad from the American toad.
Subspecies
There are no subspecies of Bufo hemiophrys
recognized.
Range
The Canadian toad's Minnesota range is
very similar to the Great Plains toad's range. It is restricted
to the western third of Minnesota. Unlike the Great Plains
toad, however, the Canadian toad range seems to stop at the
Minnesota River. Only one record is located south of this
river.
Habitat
This is Minnesota's most aquatic toad.
They live in a variety of habitats like wetlands, pastures,
forests, grasslands, even in towns. They are not found inside
dry prairies. They overwinter in Mima mounds in the north.
Habits
This toad is very similar to the American
toad in appearance, habitat preference, habits, and even their
calls are similar. Canadian toads are much more likely to
be found during the day or out and about without rainfall
than the Great Plains toad. Canadian toads breed mainly in
the spring. Their call sounds like that of the American toads'
but a single call does not last as long and is slightly lower
pitched. They hibernate communally in Mima mounds.
Food
They eat any small insects or earthworms
and may even feed on harmful invertebrates in agricultural
areas.
