First thought would be a goldcrest - though from this angle I would not be totally sure...
oh - only had the first picture when I looked now with the second I'd say - yes definitely a goldcrest - cracking little birds.

This might make it a little easier.
What to look for is the lack of any striping on the head. This bird has a plain face pattern with only a slight moustachial streak. The only real possible confusion species when dealing with a bird this size are Firecrest, Pallas' Warbler and Yellow-browed Warbler. All three have very obvious supercillia.

Yep, Goldcrest, perched in a birch (can't tell whether Silver Birch or Downy Birch)

Hi Michael;
Downy birch, would that be Betula pubescens?
looks slightly more like B. pubescens to me, but I couldn´t be sure trom this photo; probably just a Betula spec.

Hi Jörn,
Yep:
Downy Birch = Betula pubescens. Sometimes also called White Birch.
Silver Birch = Betula pendula.
That was my feeling too, looks more like B. pubescens, but not definite enough to commit myself

Many Birches are Hybrids between the two aren't they?

Hi Gerry,
Often thought to be the case, but not true - Betula pendula is diploid, B. pubescens is tetraploid, and they can't hybridise easily (and the occasional hybrids that do occur are sterile). Genetic tests have shown that virtually all so-called hybrids (apparently intermediate in morphology) are pure B. pubescens.
