Where do the crows go to roost?
In Pittsburgh they really don’t want us to know. They’re loud and obvious at their pre-roost staging areas but that’s not where they’ll sleep. After the sky is dark they leave the staging area and fly silently to the roost. Black birds in a black sky.
Wednesday evening Karen Lang noticed them near the University of Pittsburgh’s Alumni Hall around 6:00pm. Though it was dark she could see their profiles against the city-lit sky and estimated 1,000 crows were on Soldiers and Sailors Memorial Hall roof and the nearby trees.
Peter Bell saw them, too, so he brought his camera Thursday evening. From his vantage point on the 12th floor of Chevron Science Center, the roof looked like this while the crows were still arriving.
There were also on the trees.
And perfectly lined up on the roof, a couple of crows per tile.
Last night I went to see for myself. Their dark profiles were visible from Fifth at Bigelow but when I moved up Bigelow for the same view as Peter’s pictures, the streetlights’ glare made the crows hard to see.
That’s how the crows like it. When things get too hot for them, they move their roost.
Some night we’ll discover that Soldiers and Sailors roof is missing its black ornaments.
