The Eastern Wood-pewee is a species of special concern. It is declining in numbers probably due to the environment of its wintering locale and reckless use of insecticides everywhere. This is a medium sized flycatcher with a haunting woodland song often used to set a wilderness mood in nature films.

The Least Flycatcher appears to be doing well although it is hard to photograph as it moves about in its woodland haunts.

The Swainson's Thrush has a  beautiful song typical of all thrushes.

I was not able to find the Eastern Wood-pewee and Swainson's Thrush in their usual locations so I went to Dollar Lake Provincial Park, a reliable hangout for these species. The Swainson's Thrush seems to prefer higher elevations although I have encountered them along coastal forests.
