Détails de l'observation
A conservative estimate. Dark above, white below. Seen flying north just past the breaker in large numbers. I spent time placing my spotting scope on a fixed location and counted how many birds passed a particular point in one minute, and was counting just over 200 per minute, and this occurred for 60 minutes while I watched. I would check every few minutes to be sure this amount of BVSH were passing at that rate.
