Frog Blog: Panama Snouted TreefrogScinax altae
The Panama Snouted Tree Frog (Scinax altae) is a small, striped cone-nosed treefrog of the grasslands and marshes of the Pacific versant of Panama and into SW Costa Rica. It appears to be a southern, isolated sister population of the widespread Stauffer’s Treefrog (S. staufferi) which occurs in Northwestern Costa Rica and north into Mexico.
I recorded these frogs in Central Panama just east of the Tocumen International Airport. In fact, you can hear a plane taking off in the recording!
It had rained heavily earlier that day and the frogs were calling from some flooded marshy pastureland after dark. When I first heard their buzzy call, it reminded me of a Scinax species, but I couldn’t match it to any particular species I knew. It sounded like S. staufferi, but I knew that species wasn’t found in Panama. I decided they must be Yellow Treefrog species (genus Dendropsophus).
It was only after I got this record uploaded to iNaturalist that another user pointed out the correct species identification. A little research online and I ended up with another new frog for the lifelist! And a new Scinax to boot – one of my favorite Neotropical hylids.
