Fecund wasteland

The weather was beautiful today, and I decided to take a lunchtime walk around the workplace. As previously stated, this is an industrial section of Chicago's Southwest Side. It's largely concrete, tractor-trailers, invasives and litter. Still, birding is fruitful. We're not far from the Chicago Sanitary Drainage & Ship Canal and accompanying greenways. Not long ago, I saw five great egrets flying in formation over the Pulaski exit ramp on I-55. Today, eight species including: american goldfinch, american kestrel, american robin, cedar waxwing, european starling, house sparrow, ring-billed gull and rock dove.
