on an ore boat, up crossing lake superior in light haze ( dense fog ). a snowy owl found us. first it circled the ship. we are used to seagulls, it was white, but much different shape. it landed on deck and never moved evan when we walked by at say 5'. we went through the soo locks and the st. mary's river system at night. it still never moved. the next day while down bound on huron it still was motionless. the crew watched but left it alone. sometime the next night around detroit it left us. we all guessed it was just total exhaustion and needed a rest.
the great lakes are a big flyway as you prolly know. hawks, water fowl, loons at night sound spooky. bats in huge flocks. may flys in clouds miles long, flying ants that look like smoke from wild fires. and the biting flys.
