I was looked at the Global Big Day results (close to 6,000 species recorded) by big flock view and was astonished to see a record of 12,000 Blue Jays.  Looking at the checklist the observer reported counted and estimated as 1,000 birds every 20 minutes for 4 hours at a site on the Southern (US) shore of Lake Erie.  The Sibley Field Guide comments that they migrate in large flocks.
