Checked out last years' large Chimney Swift roost in the high chimney at Clark School in Webster Groves, MO.  Thursday night it was clear and I only saw about 50 enter at sunset.  It was raining last night but I'll check it out tonight and see if the number has increased.  The large number we had last year (hundreds) was on 9/16.
