Questions & Answers about Kad je park tih, slušamo ptice.
Kad means when here.
Yes, kad and kada usually mean the same thing. The difference is mostly style:
- kad = shorter, very common in everyday speech
- kada = a bit fuller, sometimes slightly more formal or careful
So:
- Kad je park tih, slušamo ptice.
- Kada je park tih, slušamo ptice.
Both are correct.
Je is the 3rd person singular present form of the verb biti = to be.
So:
- park je tih = the park is quiet
Croatian often uses forms of biti just like English uses is / am / are.
Here the clause is:
- Kad je park tih = When the park is quiet
