I got a quick glimpse of this one on a walk through the rainforest in Costa Rica. Travels singly or in pairs through lower levels of wet forest rummaging for insects, spiders, small frogs and lizards in curled dead leaves. (this as with most of my info on Costa Rica birds comes from 'A Guide to the Birds of Costa Rica' by Alexander Skutch, 1989 and I'm using the 2004-5 Checklist of Costa Rican Birds by Asociacion Ornitologica de Costa Rica for recent name changes)
