Abstract

On 25 May 2002, we observed a House Wren (Troglodytes aedon) eating a juvenile house gecko (Hemidactylus frenatus) in Golfito, Costa Rica. Just a few studies report insect-eating birds taking vertebrate prey, and we found no prior publications for this species. The recently introduced house gecko may be a new potential food resource for other native species in Costa Rica and elsewhere.
