Hyla under sonii 237 



Noble and Noble (1923, pp. 426, 429) recorded that: "//. andersonii has 

 only one call and that is given with fully inflated pouch. It is a series of ten 

 to twenty, or even more, resonant nasal quanks. If one tries to shout the 

 word quank while holding the nostrils closed, a sound is produced not unlike 

 the note made by this frog. The call sounds somewhat different from a dis- 

 tance, especially when several frogs are calling at once. Then the notes tend 

 to run together, each note having two syllables, a-quank, a-quank". 

 "i. H. andersonii begins calling in early May from concealment on the 

 ground. 



2. In the middle of May and throughout June and July the males call 

 chiefly from bushes or from trees. 



3. At various intervals throughout May and June (and some years in July) 

 when the rains have flooded the bogs and changed the ditches into small 

 sphagnum-choked streams, the males leave their calling stations and make 

 their way to the nearest of these small streams. This migration occurs 

 about midnight. The males begin calling again from their new positions 

 near the sphagnaceous streams. ..." 



They heard Anderson tree frogs from May 13-14 to July 23. 



On June 8, 1922, on our way to Okefinokee Swamp we camped in the 

 evening on the north side of Everett's Pond, N. C. near the South CaroHna- 

 North Carolina line. The instant it became dark "We heard plenty of Acris 

 gryllus, Bufo fowleri, Rana catesheiana, a few Rana clamitans, Hyla cinerea in 

 chorus, Hyla versicolor, quite a few. In the wooded sections or streams 

 following into the lake in dense thickets, S7nilax-briar entwined, were Rana 

 virgatipes croaking quite general. Fine! Several in different places. Later 

 Harper went above his tent and heard a strange note some 20 rods away. 

 The note was lower than that of Hyla cinerea, much more rapid than it, 

 possibly like it in form, yet not. In some ways it seems quite different from 

 Hyla cinerea. Captured this one nearest the tent. Another individual 

 heard near a negro cabin. We could not get it because we strangers did not 

 wish to disturb them. We heard another near the cabin. This at a distance 

 sounded quite different from Hyla cinerea down by the lake. 



Later in the evening Miles Pirnie heard one opposite our camp. All the 

 frogs heard were in or near the lake. These H. andersonii were in a stream 

 or branch with sweet gum, tangle of oaks, bamboo briars (Stnilax), Magnolia 

 glavca, maple, black gum and red maple. 



Harper speaks of the calling of these Hylas thus: "I heard the note of 

 H. andersonii at a distance of 200 yards and suspected almost at once what . 

 it was. Trailed it and after a long wait located it in some tall bushes in the 

 edge of a branch swamp. Its note bears a general resemblance to that of 

 H. cinerea but goes about twice as rapidly, is about half as loud and sounds 

 more like quak, quak, then quonk. It carried fairly well at 200 yards and 

 about 300 yards would probably be the limit. . . . Did not see it croak. Its 

 periods are infrequent and irregular, 2 minutes interval. Perhaps 15 or 20 

 or 25 notes given in one period."
