3i6 Frogs of the Okefinokee Swamp 



On July 2 at ii :oo p. m. heard only one or two near the house. On July 

 3 we heard them along the Folkston Road. "At 7 115 p. m. we started for the 

 hill. We began to hear H. squirella on our way back from the Trader's Hill 

 ponds (i mile south) and came to a pond 1/2 mile west of Trader's Hill. It 

 was a grassy overflow pool. In a clump of bushes and saw palmetto were 

 several Hyla squirella. In grassy shoals in shallow water were several, one of 

 which we photographed. In same grassy overflow were three or four Hyla 

 gratiosa calling, Hyla femoralis common, Bufo quercicus abundant, Acris 

 gryllus more or less present. This was at 9:50 p. m. There were Bufo terres- 

 tris present. Along on Folkston Road in road in temporary pools and ditches 

 with Bufo terrestris were plenty of Hyla squirella. At 9:30 I heard a Hyla 

 squirella give 67 pumps in 45 seconds. There is more vibration in the call of 

 Hyla femoralis. Could not hear the Hyla squirella a few rods away. The 

 calls of Hyla femoralis and Bufo quercicus drown it out. Hyla squirella does 

 sometimes croak from water surface when sprawled on the water." 



On July 9 we heard only one at Thompson's Landing. On July 20, 3 miles 

 from Jacksonville, Florida, we heard another about 4:00 p. m. On July 24 

 heard a few in mid afternoon at Camp Pinckney. On August i several were 

 heard in late afternoon and evening at Waycross and Hebardsville, Ga. On 

 August 8 in mid forenoon we heard many near StarHng Branch. The follow- 

 ing day in Spanish Creek woods heard them during rain at noon. "As we ap- 

 proached Trader's Hill heard many Hyla squirella at 1:00 p. m." 



On August II "at Camp Pinckney 2-3:00 p. m. heard several. At 8:30 

 returned to Camp Pinckney. No end of Hyla squirella. They were on the 

 ground in a road filled with temporary pools, water 1-3 inches deep. Count- 

 less males. Sac hyaline, more or less inflated for some time. Not so fast in 

 caUing as Hyla femoralis but swift nevertheless. Those in water greenish. 

 Those on edges of pools or in road brownish. . . . Could find no females. 

 Some males, though quite small, are croaking." 



On August 13, on a trip from Chesser Island to St. Mary's, Ga., we heard 

 them in several places but especially from 7-10:30 along the Folkston Road." 

 From August 15-17 we heard several at Callahan and Hilliard, Florida, and 

 I or 2 at Moniac, August 20. Our last record of calling came September 15, 1922. 



Temperature and humidity. In 192 1 the great chorus of "scrapers" came 

 August 5. They were calling during the rain or because of rainy weather. 

 The combined rainfall of three places around the swamp was 7.02 inches, 

 maxima 90-95°, minima 70-73°. Thereafter until August 18 a few were 

 heard, maxima 87-97°, minima 68-76°. On August 16, F. Harper and 

 Marion Lee found them calling vigorously from their tree homes in daytime 

 at Camp Pinckney when the thunder storm came on. After dark, numbers 

 were on the ground, especially in or about a wet place in the road thru oak 

 woods, where their calling was deafening. Act like Hyla cinerea, throat 

 large inflated, about half the size of the body. Scraper frog called 'Rain 

 Frog' by natives here about. One I timed gave about 15 calls in 10 seconds, 

 three times when I timed it and about 16 times in 10 seconds the fourth time. 

 A very regular and mostly continuous call.
