W Colorado link for eBird bar chart for Rufous was meant to be this one: http://ebird.org/ebird/barchart?byr=1900 &eyr=2017&bmo=1&emo=12&r=US-CO-029,US-CO-045,US-CO-077,US-CO-085
And of course Rufous is about mid-way down thru the phylo

Brian and other Hummer Fans…
SW California eBird bar chart illustrates Rufous’ northbound and southbound migration windows, kinda sorta http://ebird.org/ebird/barchart?byr=1900 &eyr=2017&bmo=1&emo=12&r=US-CA-037,US-CA-073,US-CA-079,US-CA-083,US-CA-111
W Colorado eBird bar chart illustrates Rufous as a southbound / “fall migrant” https://weather.com/weather/tenday/l/USOR0123:1:US
Extreme SE Idaho is similar in this regard (Rufous is a “fall migrant”) http://ebird.org/ebird/barchart?byr=1900 &eyr=2017&bmo=1&emo=12&r=US-ID-007,US-ID-029,US-ID-041
Sheri Williamson’s illustrations (Peterson Field Guides, Hummingbirds of N Am, 2001) on pg 224-5 give us a good look at Rufous’ northbound migration up the west coast / Pacific Flyway / during Jan-May, as far as north SE Alaska, thence more of an inland route southward during Jun-Nov
We used to think of Rufous as following an elliptical migration path, screaming up the west coast in late winter / early spring, down thru the Rockies in fall, but eBird data suggest that it’s not quite that simple, eh? =)
BNA species account (Healy and Calder, 2006) shows their annual cycle of migration, breeding, and molt (great graphic BTW), and breeding is pegged to mid-April thru mid-June, southbound migration is late June thru September. But note: my observations of Rufous in W Colorado (15 years’ worth) were from mid-June thru mid-October.
FWIW
Selasphorus rufus Rocks! =)

For E Idaho, this should be “fall” (southbound) migration for Rufous… // I should qualify this: SE Idaho
Will post some bar charts from eBird to illustrate

Thanks for all the hummingbird reports. Since Bill is on my side of state, I was interested in reading his observations & that his hummers were late. I was in Post Falls in June & family up there had 3 feeders out with Calliopes visiting all day & no others. Best views I’ve ever had of males displaying their gorget feathers within 4 ft of me. At one point, I watched about a dozen Calliopes visiting feeders at the same time with quite a bit of male bravado going on by a bird weighing less than 2 pennies!
Unless someone else has, I’ve never seen Anna’s in SE ID. I should get more observations in the next few days & can see if the Rufous have headed off. Curious, so would the Rufous appearing now be migrating back south, having already nested, at this point? Or, are they arriving late & just headed to breeding grounds?
