Článek podrobně popisuje autorovo neobvyklé setkání s kojoty (Canis latrans) v roce 2010 v kostarickém národním parku Braulio Carillio v části Sector Volcán Barva. Pořízené dokumentační fotografie umožnily analyzovat agresivní chování kojotů vůči člověku a jeho etologickou interpretaci na základě znalostí etologie psovitých šelem.

In August 2010, the author visited Braulio Carrillo National Park in Costa Rica and approached three coyotes (Canis latrans). The article describes their attack, probably due to maternal aggression combined with fear-induced and territorial aggressions.
