Who's Singing a Love Song?

In spring, many birds start singing love songs.  But it is difficult to spot the singing bird in a tree with many branches intertwined.

Here is a Ms. Black-capped Chickadee chirping a little, but the song is from someone else.  Do you know who?

Right afterward,  I found  a House Finch with the orange head singing away again.  He is a real singer for the above.

"I have an excellent voice as you might have noticed!"
