Glint of gold

I'm overwhelmed by the response to my serendipitous horsey blip of yesterday - thank you very much for the stars and hearts which got it to the second page of Popular.

Nothing so successful today; my camera  struggled to get a decent image of this fast-moving little bird that I spotted fossicking about in the mud and muck of a field gateway where cattle had churned up the wet ground. But the yolk-yellow underparts of this grey wagtail provided a welcome flash of colour even if its constant bobbing and jiggling meant it didn't stay still for an instant. Normally seen around streams these little birds often gravitate to farm land during the winter in pursuit of flies and other small insects that might have emerged.

Edit:
A couple of comments have drawn attention to the word 'fossick' which I used in the sense of 'rummage'. I wasn't aware of its origin until I looked it up - and was surprised. This is from The Word Detective website.


“Fossick” is a quintessentially Australian word, and its original meaning does hark back to the country’s gold rush in the 19th century. “Fossicking” was essentially what we would call “scrounging” for gold — searching unattended, abandoned or depleted gold mining sites for the bits left behind, small nuggets that had to be pried out of crevices or picked from streams. Judging by the citations for this sense of the word in the Oxford English Dictionary (OED), “fossicking” was considered marginal behavior and “fossickers” were not loved by more established miners.
By the late 19th century, “fossick” had made the leap into general usage with the modern meaning of “to search by rummaging around; to hunt for something.”
The origin of “fossick” is not known with certainty, but it appears to be rooted in the English (most likely from Cornwall) dialect word “fossick” meaning “to search.” The OED points to the same dialect word in another sense, that of “a troublesome person,” and the late etymologist Eric Partridge tied it to “fuss.” So evidently an English dialect word that originally meant “an annoying person” perhaps one who “fusses” over small things, was carried to Australia, probably by English immigrants, and became a term for searching for small items of value.
I've changed my title in respect of this discovery (thanks to gpzero)
