A guest question from one of the Farmer's Weekly blogs:Why did this squirrel electrocute itself on power lines, when flocks of birds routinely sit on them for hours without any problems?Tim Relf, UK
When birds land on a power line they put both feet on the same conductor. Apparently mr. squirrel attempted to move from on conductor to another, thereby completing the circuit, a mistake he won't likely make again...
I've frequently enjoyed the spectacle of possums (the Australian variety) traveling down my street via the power lines. It's very cute. They must travel extensively this way throughout my neighbourhood, and probably in every part of Australia it's the same. How the possums get onto and off the lines is something that I've never witnessed. Sadly, every year or so I retrieve a dead one from under the step-down transformer just opposite my house. Here they must traverse through a complex of cables, the upper-level ones packing 1100 volts as I recall, and the unlucky ones must contact two cables (out of phase) at once... zap! Like birds, and humans if you could manage it, they're totally safe contacting a single cable only. Bird arrive and leave via flight, they're almost never going to touch two at once. But birds know nothing more than possums, or squiirels. They're just smaller.
A crow unfortunately landed too close and completed a circuit on top of the transformer outside our house.Pop.Dozens of crows flew in to mourn for several days.
In fact, the squirrel was not electrocuted at all. It was simply auditioning for the animal version of Mission Impossible - the scene where it drops headfirst into the air vent behind the muesli cupboard.
