Are the birds MIA?

I am not an avid birder, but my neighbours are, and I do have feeders for the little guys.  But where are the finches and hummingbirds? Our neighbourhood used to have lots of birds in the spring, but this year there are few.  The hummingbirds arrived late and now seem to have disappeared.  The yellow finches were plentiful in past years but are few and far between now ... what gives?
