Bellbirds were absent until the mid 1990s, but now occur along the full length of the Styx River from Harewood to Brooklands.

They are present year-round in some sites and have almost certainly now established as a resident-breeding species, rather than just a winter visitor (as was their status from the mid 1990s to about 2007).
