Indeed a very yellow and beautiful bird. A colleague and me spotted a Yellow-crowned Wagtail the other day, which has a yellow head as well. Didn't have my camera with me unfortunately.

Thanks!

Thanks, gotta love them birdies!

I'd say it's okay. Especially with the R7 there are some pulsing issues at close distances, but for me as a beginner in bird photography it's a great combo. Duade Paton on youtube has some insights on this matter.
