Where there once was a seasonally flowing stream there is now a reservoir several acres in size. In this newly formed water body there are spectacled caiman, giant arapaima, neotropical water snakes, and a vast number of giant monkey frog tadpoles.
And somewhere on the far side of the reservoir, well away from the station's buildings, perhaps in the shallows of the reservoir itself or maybe in a remote puddle, pond, or water-filled hollow log, there are probably barred monkey frog tadpoles,
Phyllomedusa tomopterna.
At least there should be, for we have found several adults of this beautiful medium-sized hylid vocalizing from perches in reservoir-side shrubs and trees on the far banks.
Phyllomedusa tomopterna attains a length of about 2 inches. At adulthood, males are the slightly smaller sex. Although variable, the dorsum is often a forest green. The throat and chest are white(ish) and the belly is orange. The sides are a richer orange than the belly and bear broad vertical bars of purple-black. Each heel bears an easily noticeable calcar (heel spur). The soft clucking notes of the males do not have much carrying power.
These frogs are always eagerly sought on our tours and the search for them invariably introduces us to numerous other rainforest denizens. In fact, as you read this Patti and I will again be looking for this hylid in the rainforest of Amazonian Peru.
Wish us luck.
As often as not barred monkey frogs walk rather than leap.
