The north section of Westside Highway in the Cove area presents a number of small ponds visible from the highway. During the winter months, wigeon, Mallards and Bufflehead show up regularly. Beware of non-native birds as at least one pond in the area has a pet Mute Swan and some domestic geese.
The wet field just south of 158th has produced breeding Tree Swallows in nest boxes and Wilson's Snipe in winter. This field and others lining the highway might turn up an occasional Lazuli Bunting and brought the first island record for Yellow-headed Blackbird.
A good view of Colvos passage may be found by carefully following 137th Avenue off of Westside Highway down to the water. It turns into a one-lane road, so caution is needed. A turn-around exists at a small power station at the bottom of the road. Expect a good range of loons, grebes and ducks.
