Sampling comments: "Fieldwork was carried out between September and October 2009... a lineal transect of 190 m with 10 sampling units (SUs), separated 20 m from one another, was established. Each SU consisted of a circle of white paper 12cm in diameter with 5g of tuna in oil and approximately 0.5 mL of honey. These were left on the ground for a period of 2 hours"
