The Eurasian blue tit (Cyanistes caeruleus) is a small passerine bird of the Paridae family. As a residential and non-migratory bird, the blue tit rarely moves far from where they once hatched.
The yellowness of their ventral parts seems to be correlated to the number of caterpillars eaten, which contain carotene pigments, as well as the time of breeding. 🐦 🐣
Yes kids, a tit is a bird.
