Pogue Mahone

I just got back from my grandma's for Mother's Day. Usually, her house is filled with her bird's songs and chirps, but today, it was mostly mute. I say "mostly" because it did make this odd clicking sound and now and again, it would stifle a cluck. Every now and again, it would chirp. For the most part, it was fine, hopping around, eating, pooping, etc. But all the while, it was poofed out like it was cold. But the thing is, it was out in the kitchen where it gets plenty of warmth and there was no draft to speak of. Also, when it would drink water, it would act like it was choking. That's the best way I can describe it. It would dip its beak in the water, take a few sips, tip its like it was trying to swallow, then start choking like the water went down the wrong pipe. Then it would freak out, sneeze for a bit, then it would be back to normal.

Has anyone else's bird(s) done this?
