|In addition to birds, Burnaby Lake Regional Park offers opportunities to view other wildlife. Beaver are numerous in the park, and signs of their activities are everywhere. They are best seen early in the morning or at dusk. A canoe ride on the lake will improve your chances of observing them. Other mammals commonly seen include Muskrat, Douglas' Squirrel and Northern Flying Squirrel. This latter squirrel is most active at night and may be seen beginning an evening's activities at dusk.
Bull Frogs and Pacific Treefrogs live at Burnaby Lake. Their choruses can be quite spectacular, especially in the spring.
Many butterfly species find suitable habitat in the park. The most easily viewed include Milbert's Tortoiseshell, Western Tiger Swallowtail, Mourning Cloak, Cabbage White and Woodland Skipper.
