Greetings: This is really strange. Melanie and I were driving to Home
Depot and saw a small flock of crows landing on some power lines. As birds do, they
shuffled positions between a couple lines while vying for privileged spots (it's a bird
dominance thing). The snow was falling pretty hard, and I commented to Melanie that
I'm amazed that the birds hovering around the wires don't come close enough to each
other and to the lines to draw an arc. Snowflakes can carry a pretty hefty charge through
triboelectric effects as they fall from the clouds, so that added to wet birds and a
couple feet between conductors, and that adds up to a real potential (pun intended)
for an arc. Incredibly, no sooner had I finished my comment than I saw a huge
flash of light. The birds all scattered, but I did not see any bird fall. A few seconds
later, a big crow fell off a pole-mounted transformer onto I-79 below (Erie, PA, at
the Interchange Road overpass). So, while my between-the-lines hypothesis apparently
had not been the cause, it was due to the loser crow getting too close to the transformer
terminals, which are a lot closer together than the overhead lines. It's definitely
a case of being in the wrong place at the wrong time. I reported it to the 911
call center since it caused the traffic lights to go out at the off-ramp intersection.
Power was still out when we went back by about 20 minutes later, and no repair or emergency
personnel were anywhere in sight. While Melanie was feeling sorry for the bird,
I was marveling in my good fortune to have witnessed such a unique event. Would it make
me a sadistic SOB if I said that next time I pass a wind turbine, I'll be watching closely
for a bird getting whacked by a blade?

Um, yes it would, but if it happens, you'd better tell us about it!

I saw a squirrel make that mistake once... and only once. He was skittering along the
power drop to my house and heading up to the pole. Gotta admit I let out an evil laugh
since the litte bugger had been robbing the bird feeder all spring long!

I saw a huge bird of some kind get smoked by a lightning strike while sitting on a power
line. It scared the bejezus out of me - like a sign from god or something. I went right
out and played the lottery

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
