Like most honeyeaters in eastern and south-eastern Australia, the Yellow-faced Honeyeater is an active species, spending much time probing flowers or gleaning insects from the foliage of trees, but it is when they are on migration that they become conspicuous, congregating in large flocks, and thousands of birds may pass by in the space of an hour as they migrate north along the Great Divide each autumn and return south each spring. These migratory flocks often contain smaller numbers of other migratory species, especially White-naped Honeyeaters.
