Robin in the woods

We heard it before we spotted it, but got a much better view than usual. I'm wondering if it's playing "You put your right foot in ...".

The extra is a brand new infrared spectrometer with it's case removed. I was there to do admin logins for the software installation.  The first instrument of this type that I encountered filled a complete room.  This one is tiny in comparison.  I think the development may have been helped by the requirements of space exploration for instruments to be sent out to the planets.
