I was curious about prior November records of
Summer Tanager for Colorado in eBird. I see that there are only two other November records for the state in eBird: 8 Nov 2006 at Colorado Springs, El Paso and 4 Nov 2015 at Littleton, Jefferson. So it is pretty nice for November! Or anytime, of course, as it was an all red male! Many of the trees near the south end of the gravel pit are Russian olives, so maybe it was feeding on some fruit, but we did not see it foraging. I should mention it was first spotted by Karen Strong. We did manage a documentary photo or two.
Expanding beyond November, my eBird search showed 3 Colorado records for December, at Lyons, Grand Junction and Penrose. Looking back to October adds just 6 more records in eBird for that month. So the late fall (Oct-Dec) total is 12 records for the state. One on Jan 1 should be added to this, though, as that might be fairly treated as a late migrant, maybe. So 13.
