Re: Fall Hummingbird Migration

All, Hummer numbers at our SW Boise place are holding consistent with previous years. Which is to say, only 2-4 all season, and only BCHU’s. Currently the 3 juvenile BC’s continue to hang around, possibly influenced by a plethora of dense flowers, which they feed on regularly. Last year the BC’s stayed later than any of my 5 seasons at this location, last sighting about 9/12.

At our Valley Co place near Cascade, last week we still had 5 BCHU’s, only one appeared to be an adult, at our feeders, with no sightings there of Calliope or Rufous in many weeks.

Golden Eagle vs Great Blue Heron

Saw a pretty incredible, dramatic episode while floating the South Fork of the Snake River the other day. That river is loaded with Bald Eagles, Osprey and other large birds. So seeing two large birds flying towards us wasn’t out of the ordinary… until they were almost upon us and we saw, what I’m pretty sure was a Golden Eagle attacking, at high speed, a Great Blue Heron. At the last second, maybe 40′ above our raft, the eagle broke off the chase and the heron flew safely away. One of those “did we really just see that?” moments.
 

Re: Fall Hummingbird Migration

Thanks for the responses. Today, have seen one adult male BC & a juv BC Hummingbird at feeder. Both have hit feeder sev times. Think this summer’s heat & wildfires have thrown others into a different migration route. As it cools, will see if more show. In past yrs, by now, typical to have had regular visits by Rufous (a handful last mo), Calliope & Broad-tailed. 
 
Did just have a lone Pine Siskin show at platform feeder. And, have 4-5 Gray Catbirds in backyard stream willows this summer. Have nested there for sev yrs now. A Wilson’s Warbler earlier today.

Re: Fall Hummingbird Migration


Brian,

 

We live in the West Bench area of Boise and noticed a drop off in humming birds last year.  So far this year the sightings have plummeted. My semi-scientific way of measuring
this is by the number of humming bird pictures have taken over the last three years. For 2026, I have taken approximately 70% fewer pictures than 2025, to date. In 2025 I took about 20% few pictures than 2024. We also are not having to fill the hummingbird
feeders nearly as often, this year, as well. Friends that live within a few miles of us have also noticed the drop off in sightings.

 

What I don’t know is if this pattern holds in other parts of Boise, or the Treasure Valley.  May just be someone has prettier and more aromatic flowers in their garden five miles
away from us and we just need to up our gardening game.
