Personally, I have noticed an increase in Blue Grosbeaks around Fort Collins at least. Looking at my ebird sightings I counted 76 birds seen last year among 4 sites I frequent around the Fort. I have sightings in each month from May to September, most coming from Douglass Reservoir a few miles north of Fort Collins. At North Shields Ponds Natural Area, I think a pair nested because, in the same area, I saw a pair in May, none in June (nesting and secretive), a pair in July, then Adults and immatures in Aug. I also had sightings at Running Deer NA and Bobcat Ridge NA. My most interesting sighting was 2 fledglings in the third week of Sept at Douglass Res. They couldn't have been out of the egg for more than a few days. I never saw the parents and I'm not positive they were Blue Gbeaks, but they had a large grosbeak like bill. Rather late nesting (3rd clutch?) for any passerine, none the less, possible evidence of breeding there too.
-- I have a few records from Larimer County from 1988 to 1992 and none of those show any Blue Grosbeaks. My first Larimer sighting was is 2011 when I saw one that year.
