I can tell that this is a large Woodcreeper, but I don't see one that has a throat and belly with blackish streaks but has no streaks on the upper mantle. Photographed 1/10/03 11:35:58 by Scott J. Spangenberg at Villa Lapas in Playa Jacó , San Jose, CRI using a Canon EOS D60 with a 365.0 mm lens at 1/200 sec and f5.6, exposure bias +0.0 and ISO 1000. Copyright 2003, All Rights Reserved
