Same bird everywhere

I only hear one type of bird around my house lately. On this morning’s store walk I noticed the same call and response everywhere. One bird asks a question and another answers it. The answer seems to have more variation than the question, sometimes adding a couple of low notes at the end. The two sides are definitely not coming from the same bird because they sometimes overlap.

Here’s my pseudocode notation:

What is the message exchange? I imagine two possibilities:

Q: Hey babe, let’s party! A: Okay, if you’ve got what it takes. Show me the worm.

Q: I’m the biggest bird on the block! I’ll fight anyone to prove it! A: Ha ha ha ha ha.
