Most of my wagtail pics are of them foraging on the ground, which can be a fun process to watch.Yesterday while out doing some urban orienteering I saw three chasing one another around (a pair and a "third wheel"? or two males pursuing one female?) in some birch trees. When two of them took off, this one stood and posed for a while, perhaps rejected and dejected ...? But quite beautiful. Surely s/he too will find a mate.
