When a Kal-Toh player does birding.

That crest is very characteristic of a goldcrest. I know of two sub species of gold crests, one has the yellow stripe the other a slightly orange stripe and body

This seems to me like the goldfinch, regulus regulus. Not the common firecrest , regulus ignicapilla.

My information sources is the Merlin Bird spotting app.

EDIT: the correct name is not goldfinch but goldcrest. As it is not in the finch family at all.

Definitely a goldfinch with that metallic yellow wingbar.

Was the bird feeder built by very small Orcs?

Carduelis Carduelis, one of my favorite birds. They sing amazingly (plus they're cute). My mother doesn't use her lawnmower too much or at least leaves some areas untouched, so it's not rare to spot those birds. I've seen up to 20+ at the same spot, eating on the ground or relaxing in apple trees.
