Goldcrest singing

There are two territory holding male Goldcrests in my local park. Each appears centred on a large cypress. This morning, over the traffic noise, I head their incredibly high pitched, not very loud song, which appears to come from a tiny violin.
 I searched for it a bit halfheartedly, as this cypress is massive, but the Goldcrest just moved onto a smaller one. It fed, as Goldcrest do, in a rush, never stopping, but it did stop for a moment to utter his song and I managed to capture it.
This is a sonogram from the wonderful website Xenocanto of a Goldcrest song:

A pause in the sun

I watched a Goldcrest busily foraging amongst the golden leaves of a birch tree earlier today. I had not considered taking a photo until I noticed the bird had stopped. It fluffed up its feathers and sat for a rare spot of sunbathing. It has been a lovely sunny mild day today and I is the first time I see this bird sitting still.

Goldcrest acrobatics

One of the birds I find most tricky to photograph is the Goldcrest. It is not lack of opportunities. This tiny bird is often common and oblivious to human observers so it can be quite approachable. In addition, during the winter period the UK population increases with birds that migrate from the continent in search of milder climates. The problem is how energetic it is. Moving incessantly while feeding on tiny invertebrates - aphids, spiders, springtails - and their eggs in cracks on bare tree trunks and branches, or in between the needles of conifers, while constantly calling with high pitched 'see, see, see, see' notes. After a particularly frustrating photographic attempt I tried drawing the little bird (above).
 Today I searched for the first Goldcrest of the year on a front garden that has several large conifers (Norway spruce and Leilandii) and is a place where they likely breed. I heard their calls and spotted a bird high up on a bare tree, feeding upside down on the underside of a branch like unbothered by gravity. When the Goldcrest moved low on a conifer almost next to me I thought I would try a video, as I was pessimistic about my chances of success with taking a still photo. The bird obliged by performing their hovering flights at the tip of branches, and I was quite pleased with the result.
