Abstract
Papuan Frogmouths Podargus papuensis are large nocturnal birds about which relatively little is known. A prolonged aggressive interaction between two Papuan Frogmouths that involved interlocking beaks was filmed in the Lockhart River region on Cape York Peninsula, Queensland, and is described here. Two additional Papuan Frogmouths were present during the event, one of which gave a call-type (OomWoom) previously unrecorded for this species. Difficulties associated with detecting such agonistic behaviour mean that the prevalence of these contests and their behavioural significance are currently unknown and require further research.
