Blackburnian(?) Warbler, Louisville

[Paula Hansley]

CObirders,

I heard a possible Blackburnian Warbler sing a couple of times from a ponderosa tree by my house at ~8:30 this morning!!  I was unable to visually identify the bird before it flew.

This is my personal favorite of all the warblers,  so I know its song well. 

Unfortunately, crews are digging up my street, and the noisy drilling began just after 8:30.  Perhaps other migrants also arrived last night!
