Yes, just a tit. Everyone is familiar and numerous bird. However, many do not realize how diverse their lives are, and how complicated their language is.
I have been studying their hierarchy and relationships for the 2nd year now. In my opinion, their language of communication is simply unrealistic to learn. As I understand it, in their language, in addition to ordinary sounds that have the same meaning, there are various intonations. For example, they indicate danger by several types of sounds, depending on the nature of the danger (bird of prey or beast from the ground). In addition, they have accents. For example, if they tell other tits at medium distances, then "one syllable + phrase", and if they need to transmit information over long distances then "2 syllables + phrase".
I think in two years I can already write a full-fledged article about my observations of these smart (yes, they are pretty smart) birds.
