Who's Watching Who?

Well I went back to the local lakes today to check on the Tawny Owls.

I have named the one youngster the Sentinel as he always seems to remain awake whilst it's siblings snooze in the sun.

As I was walking through the undergrowth in order to better see the adult bird, I glanced up and saw today's image.

I wonder if People-Watching is as popular with birds as Bird-Watching is with people?
