They’re Back!

On 1 October I counted 1,800 crows staging in Shadyside before they flew west to a roost. Last night I counted twice as many heading toward the Cathedral of Learning. 3,600 is only a fraction of the flock that will be in Pittsburgh by the end of December. As their numbers grow they quickly wear out their welcome. Then they’ll move the roost.
