The Siskin, also called the Eurasian Siskin or Common Siskin.
Photos above and row immediately below are by Alexandra Makhnina in Kazakhstan who got much closer than I.
The male, above, has a black cap which darkens in the breeding season and he becomes less streaky (above right).
The female, above, has more streaked plumage. Both have yellow feathers in the forked tail.
Preferring tree seeds, they are rare visitors to garden feeders in late winter.
