Thanks and great capture! The colours are quite different from the one we see most often here. I did take a shot of one a loooong time ago ;-) https://365project.org/helstor/365/2013-08-05
@helstor thanks for finding your image - they are really different! I wonder if their song is similar ... I was pleased to find this one bathing then racing back to this tree to preen as usually they don't stop for a moment :)
@koalagardens Thanks for the link to the sound. Couldn't find a good link to sound of our white wagtail but from what I can hear they sound more similar than they look ;-)
