Re: [cobirds] Singing female Cassin's Finch?

I ran into a similar situation at Meyers Gulch ( Boulder County) about a week ago. Birds of the World offers two possibilities. Females sing less frequently than males and shorter songs. There is also the issue of young males retaining female-like plumage. Not sure how long that plumage is retained.

Does anyone on this list have knowledge about or experience with singing female Cassin's Finches? I recorded a Cassin's Finch singing at Grandview Cemetery (Larimer) today, that appears to me to be female. Checklist with photo and audio here: https://ebird.org/checklist/S87201022.

I'd love to know if anyone can share information about how normal or unusual it is for a female CAFI to sing like this, OR tell me that this female-type is not actually a female. I ask with humility: I don't pretend to have any knowledge of this subject.

BTW: This could be, in fact probably is, the same individual bird reported by Dave Leatherman on cobirds a couple of days ago.

Thanks,
