Abstract

In June 2012 the remains of terrestrial snail shells were found next to rocks on forest paths in several locations in northeastern Tobago, W.I. It was surmised that an avian predator had been responsible. In June-July 2013 camera trapping and direct filming revealed that a Trinidad Motmot (Momotus bahamensis) was using the rocks as anvils to break open snail shells and other hard-bodied prey items.
