Which bird of the "Paridae" family is in the picture?

The coal tit ("Periparus ater"), is a small passerine bird in the tit family, "Paridae". It is a widespread and common resident breeder in forests throughout the temperate to subtropical Palearctic, including North Africa.

The coal tit is 10–11.5 cm (4 - 5 ins) in length, and has a distinctive large white nape spot on its black head. The head, throat and neck of the adult are glossy blue-black, setting off the off-white sides of the face (tinged grey to yellow depending on subspecies) and the brilliant white nape; the white tips of the wing coverts appear as two wingbars. The underparts are whitish shading through buff to rufous on the flanks. The bill is black, the legs lead-coloured, and irides dark brown.

A favourite nesting site is a hole in a rotting tree-stump, often low down, and the nest is deep within the hole; holes in the ground, burrows of mice or rabbits, chinks between the stones in walls, old nests of Pica magpies or other large birds, and squirrel dreys are also occupied. The materials, moss, hair and grass, are closely felted together, and rabbit fur or feathers added for lining. Seven to eleven red-spotted white eggs are laid, usually in May; this species breeds usually once per year.
