Hello, you're listening to Crowd Science from the BBC World Service, the show where curiosity takes flight.
I'm Alex Lathbridge, your wingman for this episode which lifts off in Australia with the story of a hungry hawk and a brave cockatoo.
Hi, my name's Alison and I live in the southern suburbs of Sydney in Australia.
Right now I'm out on my morning jog down by the Woonora River.
There's lots of bushland nearby and I'm surrounded by lots of bird life, as you can probably hear.
A couple of months ago I was down here one morning when my attention was drawn to a flock of about 20 or 30 cockatoos about 300 metres away from where I was madly circling the treetops and screeching and squawking and making a huge fuss.
For those listeners not familiar with the sulphur crested cockatoo.
It's a large parrot like bird.
It's native to Australia, maybe about half a meter long.
It's got all white feathers and a distinct distinctive yellow crest.
Well, these cockatoos were certainly not happy and I soon discovered why.
There was a hawk nearby and one of the cockatoos was trying to see it off, being cheered on by all its mates.
