The beautiful Harlequin Treefrog (Dendropsophus ebraccatus) is a small neotropical treefrog that occurs from southern Mexico down through Central America to western Colombia and Ecuador (west of the Andes). Within its broad range, it is found in lowland and premontane rainforest and in clearings and open areas within those forests. When the forests are cut down, this species will occur in the vegetated ponds and flooded grassy areas where the forest used to be.
The frog shown above was photographed in Soberania National Park in Panama alongside a road that cut through the rainforest. The recordings were made at an artificial pond in the rainforest of Piedras Blancas National Park in Costa Rica.
The call of this species is best described as a one syllable, dry trilling "creek" sound that has an upward slur.
There is a short section of spectrogram below showing the trilled nature of the "creek" and the upward slur in pitch. You can also see that one call is punctuated with a second syllable ("creek-kck")
Here's the recording of just that one short section. You can hear the two syllable nature to of the second call.
What is most significant about this record though may be that (if I counted correctly), this represents the 100th species of frog I have recorded 🎊🎉!
