Down These Mean Streets

Scrooge McDuck, Urban Entrepreneur (Original image by Carl Barks)

There's a fascinating article at Discovery News about how birds with big brains are successful at adapting to an urban environment. The term "big brain" doesn't necessarily means "smarter" but refers to the overall ratio of brain to body size. Avian critters such as jackdaws, magpies, and wrens are urban adapters. They are able to adjust to the diverse elements that comprise the city life, in terms of food and habitat.

Moreover, there may be some natural selection at work in the avian world, as these birds may become even brainier to continue thriving in the city. As urban development spreads and paves over the preexisting natural environment, the pressure for birds to adapt will become even greater. Things aren't looking good for the yellowhammer or the golden oriole.

Life is tough when you have a small brain. ;-)

Of course, a mention of big-brained magpies necessitates a vid:

And here's the Wikipedia page for Heckle and Jeckle.

Finally, it's always good to pay a trip to the Audubon Society website.

Enjoy!!!
