The top places to see spring warblers are the shoreline migrant traps along the Great Lakes such as Point Pelee, Rondeau, Long Point, Leslie Street Spit, Thickson's Woods, Presqu'ile and Prince Edward Point. Shorelines also offer easier viewing because the cold water of the Great Lakes chills the air, slowing leaf-out. Expect 20 or more warbler species on many days in May. The late Jim Baillie, ornithologist at the Royal Ontario Museum, said the best time of day for May warblers is between 7:00 and 9:00 a.m. because one must wait until the sun warms emerging leaves and insects.
