Baby-birds are growing very fast. There is only one family left in the small box. All the other juveniles are already moved to the cages specially made for them. Vitalij and our team keep an eye on the little ones and in this video they talk about their behaviour and character. What is the difference between the aquatic warblers and other species of birds? What is the relationship between relatives? The little sick bird, along with his siblings, catches food, runs and jumps. He seems to be getting better.
