Yeah, it's time for the 'gambelii' migrant floodgates to open, though
'pugetensis' should also be tuning up. Best way I can think of for
distinguishing them by song is as follows (the management requests that you
please keep your guffaws quiet until after leaving the auditorium):

gambelii: pleez, pleez, chili-chili, pleez

pugetensis: zurr, zee, zweet zweet zue (first two notes clear, last
three trilled)

Another 'masked' migrant species: a male non-Alternate Purple Finch
Carpodacus purpureus, a species which has become quite uncommon, even rare,
in Vancouver BC without anyone noticing, was singing in the yard this
morning, the first--and probably only--for the year. A decade and a half
ago, this was a common flocking wintering bird here, but now surprisingly
difficult to find. Anyone else notice a similar drop in its numbers?
