Crows are a common sight in downtown Portland, with an estimated murder of 7,000 to 10,000 roosting each night between fall and spring.

And while there’s no polite way to say it — those birds have to do their bird business somewhere.

In fact, TriMet already spends about $1.5 million a year on a contract with Portland Mall Management to clean up their transportation corridor, known as the Portland Transit Mall. Established in 1977, the 57-block span along 5th and 6th avenues is traversed by about 1,500 buses and 300 light-rail trains daily.
