Re: Winter Wren - Millcreek Canyon

I'd like to respond to Jim's understandable concerns...

Back to last evening?I was running along the Desolation Trail when I heard a bird singing a high pitched musical song up the hill. Because I wasn't really paying attention, I initially thought I had an Ovenbird doing its flight song. So I stopped and about five seconds later the bird sang again?that's when I realized that it was JUST a Winter Wren.

As for distinguishing Winter Wren and House Wren by song...it's actually quite easy. House Wrens typically sing a bubbly song that crescendos before dropping off at the end. Going off the top of my head, the individual song itself is usually no more than 5-7 seconds long. However, a Winter Wren usually gives a series of high pitched twinkles and twitters that can go on for up to 20-30 seconds. The bird last night was probably singing for 10-15 seconds at a time before pausing.

I probably would have said the same thing five years ago. However, I?m going to disagree with Jim here. I know the older field guides (like National Geographic and Petersons) showed Winter Wren summering as far south as the mountains around Stanley, ID. I don?t have Sibley on me right now, but his maps are horrible so it wouldn?t surprise me that he showed the same pattern. Here are some summer sightings that I can remember to the south of central Idaho?

A couple of years ago I found a Winter Wren singing along Bailey Creek outside of Soda Springs, ID in July. I emailed Chuck Trost asking him about the significance of the sighting. He was delighted to report that he had seen one a week or so before in a different part of the Wasatch Range in southeastern Idaho. I also remember (or at least I think do) sightings in previous years from Farmington Canyon and a canyon outside of Logan in Utah. Maybe others can comment on these sightings. As for one Utah sighting that I do remember, Merrill Webb had one singing in July last year in American Fork Canyon. I don?t know if breeding has ever been confirmed, but these sightings seem to indicate Winter Wrens almost certainly breed in the Wasatch Range in Utah. The questions we should ask are how frequently and to what extent???

I am speculating that you heard a House Wren. Their songs are similar. A
Winter Wren would be highly unlikely in that locale this time of year.
