Although I have not had much success at seeing new arrival warblers, having seen my FOY Palm warbler only today, there have been reports coming in from other GTA locations. Someone posted seeing a B&W warbler, a Nashville warbler, a Yellow warbler, several Palm warbler sightings and even a White-eyed vireo. Unfortunately, it is impossible to cover the entire GTA every day. Checking my notes from last year I believe things started to heat up a couple of days before the end of April, so this year the migration seems to be timely.
