With headphones on I cannot hear any Lit latopalmata calls. I can however hear Lit verreauxii at the start of the call sequence and then again towards the end. Yes, both species of Cabrini calling.
I toad-ally agree with John's take on the sounds- weird as this is a loooong way away from any river system for latopalmata. Will Osborne has confirmed: NO latopalmata!
I used to do Frogwatch but needed help from @AnkeMaria on some species. This spot does not usually have much free water, if any, so was a bit surprised to hear so many frogs.
