Whampoa, Singapore – a pair of tiny Blue-crowned Hanging Parrots Loriculus galgulus (12-14 cm) flew in to an old tree which had a hole in its trunk. The male flew down from the tree top first, urging the female to come down to check out the tree hole which he had found.
When the female came down to check out the tree hole, the male did something amazing – it started to blow a yellow “bubblegum”, suck it back and blow again, to impress the female. The “bubblegum” is actually a glob of regurgitated food (which is used to feed the chicks). It seems that this display has not been documented before, and is probably part of the male’s courtship ritual to show the female that he is able to provide food for the family.
Unfortunately for this pair, the tree hole was already taken by another pair of hanging parrots, so they both flew off after a while. Good luck finding another tree hole to make a nest, bubblegum blower!
