Thanks for both your viewpoints, Carl & Larry. Will be interesting to see if any of the current Blue Jays overwinter from this year into next. Just refilled the feeder for afternoon & all 3 appeared within minutes.

Have to admit to mixed feelings of the possibility of Blue Jay range expansion. And, I was leaning toward the chance that we might be witnessing range expansion. But, I know Blue Jays feed on songbird nester eggs & hatchlings from previous experience with the jays in Texas. I also know that I would not want another songbird predator thrown into the mix, as spring songbirds already have enough challenges. At the same time, the Blue Jay is striking with its variations in blue color from turquoise to bright blue. And, definitely, the jays are not shy in alerting one to their presence! Qualities which make for a fun feeder bird.

All in all, however, hoping Carl is correct & this fall’s Blue Jay numbers represent a noticeable irruption. Again, thanks for the great information & input.

awe shucks, i’d love their raucous cacophony to become a fixture in S Idaho…..

must remind IBLE that Missy and I found a pair in Idaho Falls a few yrs ago, with one carrying what looked like gnarly nesting material

absolutely love their “personality” =)

Blue Jays move (presumably mostly out of Alberta) into (mostly north) Idaho each year in the fall. Some years it’s a few. Some years it’s a lot. This year happens to be a banner year with large numbers arriving throughout Idaho, including in more places than usual, and some making it as far south as northern Nevada, Utah, and southern Wyoming (below which they bump up against the breeding population on the Front Range). Montana is complicated because they have a breeding population (and some of our winter birds may come from there), but they also receive an influx during fall and winter. They are undoubtedly attracted to and facilitated by feeders and urbanization. While there may have been a slow range expansion over the last quarter century, this is much more a case of year-to-year variation in an irruptive species than a directional trend. Most or all of them will leave in the spring, although it wouldn’t be surprising if a few eventually began breeding in Idaho (probably initially following with a big irruption year, like this).
Good Birding,

First Blue Jay sighting was 5/16/2012 at the feeder. Then, last year, the one which overwintered, arrived on 10/21/2018 to the feeder.

Makes for some interesting questions. Are we witnessing a fall irruption of Blue Jays? Or, do we have a front row seat to observing the range expansion of Blue Jays? Is providing a seed source through feeders aiding a range expansion? Would be interested in others’ thoughts. Probably too early to draw firm conclusions, but interesting, nonetheless.

My 3rd generation farmer buddy tells me his mom, who was a hobby birder used to see the occasional Blue Jay years ago, at the family homestead, a mile directly west of me. And, as an aside, until Starlings showed, Mt Bluebirds would nest all through this area…even in their mailbox once! The mailman had them nail a box up nearby, so as not to disturb the bluebirds. That would have been in the 1960’s. A lot has changed since then.

for some reason I’ve lost track of who posted about this, that there were still a few available spots for doing these in Idaho this winter
and
Missy and I are wanting to participate this season……. does anyone have contact info for this?
I believe it was posted by someone in Oregon??

sincere thx……!!
