A tit with a cable car in its paws majestically opened the purple feathers of its wings. The fluttering of the wings of a swallow bring beautiful shadow over a modern city.

These birds have a small neat beak, flattened on the sides and very tenacious claws on their paws. As for the size, on average tits are slightly larger than sparrows, and differ from them by a longer tail. Their body length reaches 15-20 cm, weight ranges from 14 to 20 g, wingspan – up to 26 cm. These songbirds belong to the order passerine, the family titmice and the genus titmice.
The swallows, martins, and saw-wings, or Hirundinidae, are a family of passerine songbirds found around the world on all continents, including occasionally in Antarctica. Highly adapted to aerial feeding, they have a distinctive appearance. The term “swallow” is used colloquially in Europe as a synonym for the barn swallow. Around 90 species of Hirundinidae are known, divided into 19 genera, with the greatest diversity found in Africa, which is also thought to be where they evolved as hole-nesters. They also occur on a number of oceanic islands. A number of European and North American species are long-distance migrants; by contrast, the West and South African swallows are nonmigratory.
This family comprises two subfamilies: Pseudochelidoninae (the river martins of the genus Pseudochelidon) and Hirundininae (all other swallows, martins, and saw-wings). In the Old World, the name “martin” tends to be used for the squarer-tailed species, and the name “swallow” for the more fork-tailed species; however, this distinction does not represent a real evolutionary separation. In the New World, “martin” is reserved for members of the genus Progne. (These two systems are responsible for the same species being called sand martin in the Old World and bank swallow in the New World.)
