No specific study available, with most data coming from published anecdotal reports and specimens examined by Lambert and Woodcock (1), held at the Sarawak Museum, Kuching, Malaysia.

Feeding

Main Foods Taken

Principally insectivorous, but recorded eating all manner of small riverine animals including mollusks, snails, crustaceans, and small fish (54, 46, 47).

Food Capture and Consumption

Poorly documented. Prey are typically seized from the ground and water’s edge (2).

Diet

Major Food Items

Invertebrates recorded on specimen labels at Sarawak Museum, collated by Lambert and Woodcock (1), include a longhorn beetle, a green-and-bronze beetle (Coleoptera), ants (Formicidae), crickets, large grasshoppers (Orthoptera), hemipteran bugs, and a caterpillar. Sharpe (55) found the gizzards of two young birds to be full of caterpillars and beetle remains and, in one bird, a small snail. Robinson (56) observed Black-and-red Broadbills on the Thai-Malay Peninsula catching large blue-and-yellow moths (Lepidoptera) over small streams. A specimen held at the Natural History Museum, Tring, is recorded as having three seeds and a green leaf in its stomach (1), while pips were found in a specimen collected by Chasen and Hoogerwerf (57). Both these snippets of information suggest a degree of herbivory in Black-and-red Broadbills, although this is likely to constitute a relatively insignificant part of this species’ diet, and it is plausible that these items were taken incidentally.
