The Olive-sided Flycatcher was heard calling repeatedly twice and seen once, albeit a silhouette of a Flycatcher. Because of the call being so unique to this species, a somewhat melodic "quick three beeeers", I have no doubt in my ID'ing this as an Olive-sided. Although I myself have never seen or heard this species along the Bluffs before, I know they do breed in at least one area of Scarborough still. It's likely that this bird will not stay long in the area and may have already continued onward. It was last seen flying eastward out of a tree on the east side of the park.
Like all green spaces along the lake in the GTA, Rosetta McClain Gardens is located on a major flyway for both spring and fall migration so you just never know what is going to drop in and say "hello".
