EL Kadarum 1954/5 Bufo boreas Jan. 10 1.3 mi. N, 0.2 mi. W Civic Center, Richmond, Contra Costa Co., Calif. Visited this area following heavy weekend showers which ended sometime during morning hours. Today the weather has been overcast and windy - cool temperatures as we've had for many weeks. Water temp. 4:30 P.M. 11.5° C., air above dense grass 11.0°C. Overcast, but intermittent sunshine along with cool winds. Ponds high with water. Few Faw Hyla moles out and sporadically calling but no eggs laid as yet. Some Hyla under broad litter, few Batrachoseps but no Bufo, Feb 1 Same locality. Checked very large pond to W side of N-S running SP tracks. Hyla in someones shores. Moles near edges, on vegetation or litter surface flutter out in water. Water temp. 7:35 P.M. 9.50 C., air 2" above water 8.2°C. Air over dry grass surface 5.8° C. Moderately NW breeze, clear sky, bright 3/4 moon. Water level up about 6" from last visit, and this pond probably 10-15 yards wider than in January. No sign of toads or eggs. Air temperature predicted 35-40° tonight, feels it now here. It seems too early for toad breeding. Hyla egg deposition has just begun as evidenced by half dozen egg clusters recently deposited. (See Hyla notes)
