I've been thinking of looking for Marbled Frogmouths near Brisbane (heard one once this time last year at Mt Tambourine). Can people give me any good ID hints for separating these guys from the common Tawnys.

Plumed Frogmouths call any time of year, but are best in September to December. ID from Tawny is not really much of an issue. If it's easy to see and out in the open, the chances are extremely high that it's a Tawny. If it's extremely difficult to see, was found by following its call, and is high up in a rainforest tree surrounded by dense vegetation, then it's probably a Plumed. In terms of plumage, there are several differences, but they are hard to see and subject to a great deal of variation. Possibly the single most useful feature is that the primaries are banded with brown as well as black and white in Plumed, just black and white in Tawny, but even that is probably not 100% consistent.

At this time of year, they are likely to call just before dawn and just after dark, but may not say anything all the rest of the night. A very exciting way to see them is to track them down from their pre-dawn calls. If you get lucky, you may find them roosting, which can be high up in a tree or low down, even on the ground. Be warned, they are very shy during the day, so your approach must be very careful!

Cheers, Chris.
