On the banks of rivers, lakes, ponds, and marshes, as well as in floodplain and coastal forests, among thickets of willow, reeds, and reeds, one can see bird houses resembling a bag with a tube sticking out of the side. These are the nests of a small bird called Remiz (Eurasian pendulines tit). Most often nests are placed at the ends of branches hanging over the water. The Remiz nest is about 17 cm high and 11 cm wide, with walls about 2-2.5 cm thick. Despite such thin walls, the nest is very strong and serves Remiz for many years.
To build the nest, plant fibers of flax, hemp, nettles, and other fibrous plants are used. On the outside, Remiz pokes fluff of flying seeds, pieces of birch bark, willow and poplar earrings into the nest. The result is a fluffy house.
The female starts the work by building the nest, then the male joins her and they work together for about two weeks. In the finished house, the female lays eggs and starts hatching. At this time, the male starts building a second nest, fertilizing the second female at the same time. If the male has enough time, he builds another nest for the third female.
