Thousands of chimney swifts swirl above Charlotte at dusk, but the old brick chimneys they depend on are disappearing

At first, nothing. Then, in threes and fours, black shapes swooped through a twilight sky. Soon, they were joined by others, all chittering in high, alien voices. 

A handful became dozens, then hundreds. Finally, they were a swirling flock of more than a thousand, wheeling in a counterclockwise vortex until it looked like the very sky was alive.

The chimney swifts were returning to their evening roost in an old chimney at East Mecklenburg High School on a recent night, with their human fans watching in wonder below. The massive flocking — part of the birds’ preparation for a 3,000-mile migration to South America — is a sight fewer in Charlotte may get a chance to see. That’s because swifts are losing the large brick chimneys they rely on for pre-migration roosting.
