Can you only play one bird in a turn?

So we’ve had the physical game for a while and I just tried out the pc version and I wasn’t able to play multiple bird at the same time on it.

The way we have been playing is like, if I want to play bird cards, I would go to the farthest right available spot and play one, then go back to the next available spot and play another, then if I really planned it, play one in the last row if they are staggered like that. Playing one per column. (Granted if I have the resources for them)

But I couldn’t figure out how to play multiple birds in the pc version. I could just play one and it would end my turn.

Maybe we are playing it wrong or maybe I’m dumb lol.
