Two singing Black-throated Blue Warblers, Louisville, Boulder County

[Paula Hansley]

I was trying to record one singing warbler in a bush across the street when another one started singing from my catalpa tree!

With all the snow falling, it is difficult to find this dark warbler!  I am now going out to try to photograph one of the birds as they are staying relatively low in the bushes or trees.

If you decide to come here, familiarize yourself with the song (a series of buzzy "zees", sometimes on one pitch, sometimes rising and descending).  The song is not loud.
