Traplining

Hummingbirds forage by revisiting flowers and it is thought that they do so by following routes or sequences that are repeated through time (traplines). To determine if this is in fact the case, Maria recorded the order in which hummingbirds visited an array of 2, 3, 4 and 5 flowers.

This diagram illustrates how additional flowers were added to a hummingbirds foraging table to see whether it would visited them in a predictable order
