The Dollarbirds (Eurystomus orientalis) were nesting again at the Changi Boardwalk. Constructed from palm stems, probably nibong (Oncosperma sp.), the rotting top portions are favourite nesting holes for these birds. These hole nesters make use of the natural cavities as they are not able to excavate their own. There is an earlier post on the nesting in 2006.
James Wong a.k.a. Jw73 documented the birds bringing insects to the nestlings and are sharing his images with us here (above and below).
According to Fry (2001), Dollarbirds take large insects like beetles, mantises, grasshoppers, shield-bugs, cicadas, moths and termites. The image above (right) shows an adult bird bringing a shield-bug (Cantau ocellatus) to feed its young. Insects are usually caught in flight and brought back to the perch where they are shaken rather than beaten against the branch.
