Haven't heard any gaper these days warned about danger of 'catching a fly' but it's surely fitting for Australian Bustard (Ardeotis australis) at Mungalla Station. Always plenty of the blighters hanging around the cattle.
Not so many in the higher altitude at the head of Wallaman Falls, where this Golden Whistler (Pachycephala pectoralis) spent quite some time opening wide and letting rip.
A bird only too happy to have any flies and other flyers about the place, Rainbow Bee-eater (Merops ornatus) takes off at Tyto in pursuit of aerial prey. Chance are it would not not be a bee, in spite of the name. The birds show preference for many other insects before chasing tiny native bees (all stingless) or more formidable European honeybees.
