I read Lennie's post (via Peter's message) with great interest. I have been conducting informal pre-dawn auditory thrush survey's in the Southern Kettle Moraine in both the spring and the fall seasons for the past two years. Not only can you hear song & song fragments, but call notes along with some nervous cries as they take notice of YOU! For example, the Hermit Thrush makes a "jway" sound and the soon to arrive Swainson's Thrushes make a funny squeal-like noise! This morning, I counted a minimum of 6 Hermit Thrushes at a woodland patch.
