I didn't get up so early today but a morning's sampling of a few sites in the Whitby area produced the following:
Cranberry Marsh: American Bittern (showed for ages) & American Kestrel (juv heading purposefully south)
Thickson Woods: Chestnut-sided, Canada, Wilsons, Black-throated Blue Warblers, American Redstart, Olive-sided and Great Crested Flycatchers
Oshawa Second Marsh: SB Dowitcher + peeps + bucketfuls of rain!
