When I first noticed the bird I only saw a single Dollarbird but then a second one arrived. One of the birds flew from the tree to catch an insect in flight. It returned to the other Dollarbird on the branch, still with the insect. I thought it may be about to feed a young bird in the tree but it flew off to the south to another strand of trees. The second bird also disappeared. If there were young they were not in the tree I was at.
