Have you ever seen a red-throated loon? A Barrows golden-eye? An Iceland gull?

Winter is the best season for harbor wildlife. Join Ron Harrell and Gary Gulezian on the Belfast Footbridge Saturday, Dec. 9, from 8 to 10 a.m., to watch ducks, loons and other birds in the harbor. Harrell and Gulezian make learning easy and fun! Bring binoculars, look through their scopes and wear warm layers.
