The bird trinity

Titmouse, chaffinch, blackbird.

It's a kind of "holy trinity".
If you go into the woods or to a bush somewhere, you will always find these birds there.

The chaffinch is probably Europe's most abundant bird, with a population of perhaps 200 million in Europe.

Blackbird populations are divided into two groups: forest and urban. Urban blackbirds mature sexually earlier, which is attributed to urban artificial lighting.

And what to say about the titmice?
For example, that this cute little bird can be very aggressive towards other, smaller bird species when looking for a nesting place.

In England, it has learned how to split the aluminium lids of milk bottles and suck the cream underneath. This skill was first observed in 1921, and over the next two decades it spread rapidly among hen titmices.

So watch out for the titmice, lest they drink your cream.
