Having looked the video again at Full HD (what a difference for judging the head-pattern), the Bunting at 8:11 is indeed a Yellowhammer imo, evrything is there. It has just a slight uniformer head-pattern than "ID-book" YH.
Agree with Mummymonkey, that the unsharp bird at 2:21 looks like a Dunnock. Not a sure ID, but if seen this bird in Germany, I would make a quick jizz-id of a common bird, as nothing seems wrong for a common species.
Agree with Mummymonkey that the Bunting at 8:14 is a Yellowhammer:
wrong head pattern for Cirl, but it is good, really spot on for Yellowhammer and the warm brown rump with a slight rufous tinge is just visible.
The Bunting that is chased by a Greenfinch at 8:11. seems a slightly odd...
