Carduelis carduelis (Linnaeus, 1758).
Length 12-14 cm. Easily identified by its brilliant colors: black and white head, red face, black and yellow on the wing, bold whitish rump, and black tail. The Goldfinch is found in gardens, orchards, and farmland where there are weeds, especially thistles. It can be seen in small flocks during winter and is notable not only for its colorful appearance but also for its lovely springtime song. It is a granivorous bird and eats seeds and also small invertebrates. The nest is a neat compact cup of roots, grass, and cobwebs, lined with plant down, wool, hair, and occasionally feathers. The 4-6 eggs are incubated by the female only. This bird is a common breeding resident and winter visitor. In Egypt, it is found in the Nile Valley and Delta, several Western Desert oases, and in northeastern Sinai.
