Unknown. Mating call. The call of Hyla praestans consists of a primary note followed by one or two, shorter, secondary notes. Analysis of a single recording shows that the call groups are repeated at a rate of calls per minute. The duration of the primary note is sec. The fundamen- tal frequency is at 450 Hz, and the fifth harmonic at 2,250 Hz is dominant (Fig. 3). Distribution. This species is known from elevations of 1,750 to 1,970 m on the lower eastern slopes of the Cordillera Central next to the upper Rio Magdalena Valley, Colombia (Fig. 1). Remarks. The region of the type local- ity is humid lower montane forest with bamboo, Heliconia, and some bromeli- ads. The exact type locality is a small, temporary pond immediately behind (±100 m) the Museo Arqueoldgico San Agustin. Males were calling from a tangle of brambles over (up to 1 m above) the water at night following a light rain (13 mm). Etymology. The specific name, praes- tans, is Latin meaning preeminent or.
