Wayne and Tweeters, There have been two reports of Clark's Nutcrackers in Clark County including one in a low elevation location and three reports this year of them along the Columbia River in Skamania County this year, but no out of place Mountain Chickadees yet. I looked on this year's Clark's Nutcracker map on the eBird Bar Charts page and it shows few low elevation sighting reports this year. Wilson Cady

Joshua and Tweeters,

Your comments about recent Mountain Chickadee sightings in the Puget Sound Lowlands are quite astute, and I second your recommendation that birders keep their eyes (and ears) open for this species in the coming weeks and months.

The bird at a feeder in Coquitlam, BC is still being seen through today, October 12 (although not recently reported to eBird). In addition, 2 Mountain Chickadees were reported on October 4 at Blackie Spit Park in Surrey, BC, and one of these was photographed.

Small invasions of Mountain Chickadees into the Puget Sound Lowlands have occurred about once or twice per decade going back at least to the 1960s, and this may prove to be one of those years.

There has also been an outbreak of Clark’s Nutcrackers into areas far to the west of the Cascade crest, where they are not usually seen. In recent weeks, there have been Clark’s Nutcracker reports from Seattle, the San Juan Islands, Hurricane Ridge near Port Angeles, Sauk Mountain east of Concrete, and in the Mount Baker area.

In the past, irruptions of Clark’s Nutcrackers and Mountain Chickadees have sometimes occurred in the same year, although movements of nutcrackers into the lowlands are much less frequent than those of Mountain Chickadees. The reasons for these movements are not clear, although I suspect it is related to food availability, especially for the seed-eating nutcrackers.

Good birding, and here’s hoping for more nutcracker and Mountain Chickadee sightings!

Hello Tweets,

Maxine Reid's sighting of a Mountain Chickadee in Tulalip Bay yesterday reminded me of two other recent sightings of Mountain Chickadee in the Salish Sea area within the past two weeks: one bird at a feeder in Coquitlam, BC at the beginning of this month; and one at the base of Ediz Hook in Clallam Co. on October 6th. To me, this seems to indicate a minor movement of the species into the Puget Sound area, though the cause is not quite clear. For this reason, I recommend that birders check all their chickadees especially closely in the coming weeks -- you never know when you will stumble on that white-eyebrowed, wheezy-voiced individual! Coastal stands of Douglas firs seem to be a major point of attraction for wandering Mountains.

Good birding, Joshua Glant
