Thank you Christian and Keith Arnold for the confirmation that Carolina Wrens
have a quiet song like this. I couldn’t find a match in MacAulay or Pieplow. I
live at the nw edge of the CAWR range in sw Iowa, and don’t hear Carolina Wrens
very often and never have heard this song. Birds of the World Online calls it a
subsong that juveniles sing until they leave their natal territories.
I appreciate the help folks have given me as I learn the local ropes.

I’m definitely hearing a Carolina singing a quiet version of the song at 0:19
or so.

Today I encountered a song in riparian brush along Cypress Creek in nw Houston.
My first thoughts were either Am. Goldfinch or House Finch, but neither seemed
right. I tracked the bird down, and saw it singing the song, but it stayed in
darker undergrowth. It was clearly a wren, and I could distinguish a
well-marked pale line above the eye, typical of Carolina Wren (or Bewick’s).
The gizz as it moved was Carolina, but the song at best was atypical. My
tentative conclusion is that it was a juvenile (hatch year) Carolina that had
learned a song of one of the other species mentioned above (not Bewick’s).
Goldfinches and House Finches have both been singing in the neighborhood,
although goldfinches have mostly departed in the last few days. I’ve attached a
spectrogram and recording, both of which are poor, but might give an idea of
why this bird presented a dilemma.
I’d appreciate any comments-
Thanks,
Ross
