Here in Oz we don't see that many Eagles in the Eastern states, but there are heaps of Eagles up in the Northern Territory that live around the Stuart Highway. This road has no speed limit, so all the locals drive big V8 cars and turbo sportscars and big bikes, as they should.
Anyway, there are also many trucks, "Road Trains" pulling 3 or more trailers, and the "tractors" are enormous Macks, or White's or Western Stars etc, so the local fauna, when it ventures out, doesn't stand much of a chance, thus providing free food for the Eagles. Because they're so well fed, it's nothing for some of these bad boys to have wingspans of 6 or 8 feet.
I often marvelled at them swooping in and picking up a whole Wallaby or a Roo and just flying away with it, but in 1995 I was in the army on joint exercise with the US Marines, and one truck being driven by a couple of unfortunate marines had an Eagle go through the windshield and, apparently unharmed, begin to express it's displeasure at the driver and passenger of the truck as they tried to slow from 60 Mph so they could safely get the f*ck outta that truck! The boys got a bit scraped up in the process but everyone (including the eagle) survived the ordeal, and there would have been some stories told when those boys got back home, ha ha! Cheers, Terry.
