Same thing down here David. I was talking about the coastal lowlands. For
instance they do not breed at New River, Coos which is heavily forested
although with lots of shore pine but big spruce on the ridges. You don’t
pick them up breeding regularly until you get inland. Also most Mamu
habitat is a bit older forest which fits well with preferred varied thrush
habitat. I am up predawn every day for years and this is first year I have
heard varied thrush in Mingus Park in June...
