Many will know I’ve mentioned my theory about Brown Falcon’s ability to ‘map’ out an area and fly, following that internal map.
I came across an article in The Smithsonian Magazine recently titled, Why Do Some People Always Get Lost.
The interesting part to me is toward the end and titled Mental Mappers. I can’t provide a direct link, and it’s a long scroll down. It refers to “….the specific skills that are hallmarks of good navigators These include the ability to estimate how far you’ve traveled, to read and remember maps (both printed and mental), to learn routes based on a sequence of landmarks and to understand where points are relative to one another.” ” Two of those skill are ‘Route Following’ and …and what’s often termed ‘survey knowledge,’ the ability to build and consult a mental map of a place.”
When my Mother-in-Law was getting on in years the family pointed out she was unable to move around on her own as, “She didn’t know where she was.” Now, I had to take exception to that as I’d travelled about with her quite extensively and was more than confident in her ability to go from home, to the shops, pick up a bottle of milk and return safely. And to venture in and out of several stores along the route. I discovered that they were judging her lack of ability because they had taken her to a shopping centre she’d never been to before and she had asked, “So, how do you get out of here?” I’m certain I’d have done the same. New place, new location, no mind-map.
As a young tacker, I grew up with a highly respected bushman. He could wander about for hours and still know where he was, where the start point might be, or the next spot to go visit. His simple secret was he named locations as he went along. Easy to remember names, like places, “The Eiffel Tower”, “The Burnt Log”, “Wombat’s Home”, and others. The landmarks would be no more than 200-500meters apart. So if he was somewhere, all he had to do was find one of his landscape features and follow back from there. When I walk the Eynesbury Forest, or the Woodlands Historic Park, I still use that system.
I’ve sat for an hour so so with so many Brown Falcon’s and watched them watching. Then when they fly, it’s a deliberate run at almost ground level, to swoop on something, or onto the next chosen perch. As they slip past a bush here, around a plant there, through an opening in the grass, it’s hard not to be impressed at their mapping ability.
And just in case you never leave home without GPS, here is a conclusion from the study.
…A follow-up with 13 of the volunteers three years later revealed that those who had used GPS the most during the intervening period experienced greater declines in their ability to navigate without GPS, strongly suggesting that GPS reliance causes diminished skills, rather than poor skills leading to greater GPS use.
We’ve also been following a pair of Black-shouldered Kites. They fledged two young about two months ago, and the young, as normal have now moved away. As soon as her young fledge, the female usually hands responsibility of their care and feeding to the male. She then takes a few weeks extended leave, and goes off to replenish her system from the 8 weeks or so of sitting on the nest.
For some reason this female had not returned for about two months. Her male kept station and I was beginning to think he was on his own.
However the other day, we found them both hunting in the paddock.
The picture on this page is of her sweeping in with a catch. Not sure if she took the mouse, or if he’d passed it on to her. Will have to wait to see what, if anything develops.
