馃 The great tit (Parus major)
馃摎 Parus (lat.) Tit
馃摎 major (lat.) large
As soon as the temperature rises and becomes warmer than usual in winter, adult high-ranking males begin to sing a mating song. They do it quietly, singing modest two notes.
Then closer to spring, by the end of February or the beginning of March, the song becomes louder, more and more males sing it, and it already consists of three notes.
This is how pairs are formed, but the birds still live in small flocks anyway. Until it gets quite warm in April. Then the birds fly away to the forests.
However, some birds do not fly away to the forests, but remain to live in the courtyards of city courtyards. Since autumn, I have been taming all the birds that fly to my feeder, so I noticed that those birds that remain to live in the yard are some birds that are not familiar to me, they are not tamed.
To be honest, I still don't know why this is happening. For 5 years of studying great tits, I have not yet found out.
