![]() The owners of the transmitting equipment in the video, AT&T California, say the incident occurred in 2009. Oaks, acorns, and the geographical ecology of the acorn woodpecker. Watch the video showing technicians clearing a huge cache of acorns from a transmission tower. It’s nearly the size of a crow, black with bold white stripes down the neck and a flaming-red crest. Walter Koenig, a senior scientist with the Cornell Laboratory of Ornithology, says he’s pretty sure the the acorn woodpecker (Melanerpes formicivorus) was behind the cache.

They analyzed the costs and benefits of joint nesting, hoping to explain why some woodpecker females exhibit this rare behavior. The Cornell Lab of Ornithology - All About Birds - Downy Woodpecker Chipper. Woodpeckers put 220 kg (485 lb) of acorns into a wooden water tank in Arizona. Occasionally the woodpecker will put acorns into places where it cannot get them out.
