This should not be difficult for some here.

I'm in Halifax Nova Scotia. It is July.
Early this morning just before and during sunrise, I heard a strange call, almost too funny!! The last note is the unexpected note, it almost seems to be a blunder ending of a wonderful bird song!

The song consists of not more than 5 notes, no buzzing, no clicking, pitch changes, just very plain simple notes I describe below.

The first 3 F#'s could be only 2, it seems unclear. The 2 notes at the very end of the song have more space between them than than the beginning notes. The whole song is done in less than 5 seconds. The last note is a surprise, as if the bird throws it in for the surprise finale.

This is the pattern, letters indicating pitch on a piano keyboard from here:

Thank you so much for your help, I cannot find this bird, and the neighbours don't know either.
