Advertisement call variation and male mating success was investigated in a population of the Arizona tree frog, Hyla wrightorum , from central Arizona. Dominant frequency of advertisement calls was significantly correlated (negatively) with male snout-vent length. Males found mating were not significantly larger than nonmating males, nor was there a significant correlation between sizes of males and females found in amplexus. These results are discussed in relation to Renaud's (1977) work with H. wrightorum and in light of recent work with anurans in general.
