Itinerary
July 17
Paterson 250 ft., Benton Co., Wash.
cheat grass and Russian thistle.
Between 8:45 and 9:15 P.M. 24 Scaphiopus
were caught in a pond along the
edge of the river. The pond was
shallow and surrounded by
willows on 2 sides and the river
and a gravel bar on the other side.
Coarse grass or edge was growing
in and along the edges of the pond.
The toads were numerous and could
be found sitting at the edge of the
pond in the wet grass or in very
shallow water. Breeding is in
progress as angelfus was noted
in 2 cases. Voice or sound made
by the toads resembles neither that
made by Hyla or Rana but is
a high harsh note which is fairly
prolonged. When caught and placed
in a reptile bag, the toads utter
short croaks which resembles
very much the notes made by
young chickens.
