are still calling. There is a definite triggering effect of one call on others. I approached me -> to within 4 feet.
The color phase is deep olive green-brown as in that of other males seen. The whole body appears to quiver during the call. Body 1/4 immersed in water, 2:40 P.M. Mother -> seen walking over surface of a dry 6'x5'x6", at plopped into nearby pool 8" deep like froglet style when I approached.
This behavior noted many of the adult toads if a larger pool of water is available. Otherwise, they can lose quite rapidly (for a toad) cleaning 6" of ground per leap.
The entire meadow area is a contrast in brown and white, snow covering 2/3 rds of it. I ascended SE up to the upper parts. Tenje. man stream (snow all around it) 16.4° C. 2:50 P.M. No Rana seen and few Bufo adults calling. Mild sunny afternoon.
A few Bufo can be heard calling intermittently from the upper part of the meadow. In a shallow (to 6") runoff pool 150' across I came on an adult F. Quiescent in 2" water, only eyes above surface. Surround 18.9° C.; water same. Air above pool (shaded-shaded) 17.5° C. & overigus. Snow depth in meadow to 2 1/2' maximum. Free of snow around borders and where the larger streams and runoff pools have formed.
