Sexes alike...

Goldfinch can be sexed on the amount of red stretching behind the eye, above the eye.If the red stretches well back, past the eye, then it will be a male. This bird on the right is definitely a male, on that basis. On a female, the red above the eye tends to be much less, and also the red below the beak tends to be less defined and shorter than on a male. A large number of birds are intermediates, though, so it only works with well-marked, adult birds.

If you can see the lesser coverts, on the birds 'shoulder', then black is a male and brown a female, but that can be tricky to see and again many are intermediates.

Thats a fine difference, I suppose not so easy to make it unless with a very keen observation. It is good to know. Thank you for explaining.
