Harrison Lake is the largest lake in the southern Coast Mountains of Canada. Located in the Fraser Valley east of Vancouver, it covers about 250 square km (95 square miles) and is about 60 km (37 miles) long. This may be why it snares a good share of bird species that would be more typical of a pelagic birding adventure.
Harrison Lagoon and the nearby East Sector Park are two spots at the southern end of the lake that are worth birding any time of year. They feature a variety of habitats, attracting a wide range of bird species. On a spring or fall morning, it’s not unusual to see more than 50 species.
An added bonus is that I never know what surprise will pop up. Shorebirds are annual migrants, and they often provide very good views as they feed in the lagoon. Migration brings many sparrows and the occasional Horned Lark and Lapland Longspur to feed in the stunted shrubs and grass.
After birding the lagoon area, I put away my scope and head to the forest in East Sector Park — an excellent site for songbirds. This includes annual breeding Hutton’s Vireos. The park offers varied forest types, a marsh, and a slough.
Directions
Harrison Lagoon is located at the southern end of Harrison Lake, and East Sector Park is located 1.2 km (0.75 miles) to the southeast.
