Thanks, Paul.
The casque above the beak is the resonator for the sound they make.
There is a larger rare species, the silver-cheeked, with an even bigger
casque. They use the beak proper to catch large insects & tear fruit
like figs from trees.

Great images - is all that bill functional or just an anomaly of nature?

We were graced by the noisy arrival of a pair of Trumpeter Hornbills
in our garden this morning. Difficult to photograph because they are
only in the open when flying & are easily disturbed. These are
riverine birds rarely seen in town. I grabbed my camera & slowly
snuck into position. Managed a few shots before they flew off. Here
are the two best. Scroll R for the other.
