The only alteration I made to the recording was to amplify it some.

I agree with you, Mike, though I hardly have the expertise that you do.

The suggestions of Purple Finch and Robin come much closer to matching the “quality” of the sound, to my ear.

Hmmm.....
Having done many years of marsh bird monitoring in the midwest (another region where Sora are common), I've never heard a Sora give it's two-noted call in a fashion like this one. This call is much mellower and more liquid sounding than the Sora's high-pitched "pu-weeep". The timbre and lack of intensity are all wrong for Sora (unless somehow the recording has been edited).

Kay,

Thank you for sending me the audio file, and the added information that there is a wetland with Red-winged Blackbirds.

I will say with firm conviction that this is a SORA, and not a Hutton's Vireo. It is two-noted and up-slurred. The initial note is longer. "pooo-WEEEP"

A Hutton's Vireo does a higher pitched, also up-slurred call, but shorter: "s'WEEEP , s'WEEEP. s'WEEEP"

I can imitate both species (I speak the language), and I've had conversations with both of them. I don't know what I'm saying, but I know what they sound like.

I can confirm that the other call is, indeed Red-winged Blackbird. The recording was made on the edge of a small wetland that hosts them year-round.



Most responses have leaned towards Hutton�s Vireo, which is also on my list of possibilities. I�ve never heard one quite like this, but then I had an experience later the same day that emphasizes that identifying birds by ear alone is not always as reliable as we�d like. I�ll post about that shortly.

I recorded the attached at about 8:00 AM on Thursday, 7/2, in Canby. I was never able to see the bird, which seemed to be deep in a group of curly willows. It called continuously for several minutes. I feel like I ought to be able to put a name to it, but I'm not having any success. Any suggestions? (I'm after the repeated 2-syllable "do-whit" call.)
