Usually Kings Pond, at the end of Ascott Road off of Cedar Hill x-road has Wood Ducks, as does Mystic pond in Cadboro bay...
if you are looking for warblers and a very good variety of bird species, the powerlines around munn road and prospect lake road are fantastic. Here is the link to the hotspot on e-bird. http://ebird.org/ebird/hotspot/L1204220 ... sortBy=spp
There is a pond by the powerstation that is good for a number of species. Also you can dip into Francis King part in any number of areas to get some species that are more typically forest dwellers. The powerline swath is great for some sparrows, macgillivray's, orange-crowned warblers, woodpeckers, especially red-breasted sapsuckers listen for the distinct drumming pattern), purple finches, willow flycatchers, black-headed grosbeaks, plus fly-overs of raptors and others. The surrounding forest is great for other species such as hutton's vireo, black-throated grey and townsend's warbler, olive-sided flycatcher, etc. Check out the bar-charts on the ebird link. I am just listing these off the top of my head. I love this spot because you get a great variety of birds and can get all of the breeding warblers and vireos. There is usually a pair of Cassin's vireos around the Francis King Park nature house, or on the swamp trail across the road.
