Think it must be habitat. The only year I had numbers like yours, was 1988, summer of Yellowstone fires. I had 3 feeders draining daily with: Broad-tailed, Rufous, Calliope & a few Black-chinned. After that, for about 10 yrs, our most numerous hummer was Broad-tailed. Then, became Black-chinned. And, that’s been our typical summer resident hummer, since. BT have about disappeared, only a couple Fall migrants, usually late Aug.

I wonder if it’s habitat difference. We have some nearby riparian area with Rapid Creek west, but lots of open fields and aspen/pine fir boundaries. We’ve both been feeding for years.

Happy to have them and Sandhills.

Don’t have near your numbers, Bill. But, getting both male & female adult Rufous & Black-chinned Hummingbirds hitting the nectar, esp AM & evening time. No juveniles yet.

 

Juvenile-wise: numerous BH Grosbeak, Bullock’s Oriole, Robin, Spotted Towhee, Yellow Warbler young about. Best bird this AM was a Gray Catbird working through backyard streamside willows. Only a handful of House Wrens this year, usually have a dozen + about.
