My budgie keeps yelling

I have an adult budgie, 1 year old male. We are out on a holiday as a family which includes the budgie. We downsized his cage a bit to carry him easier. We let him out twice a day for long but in the mornings he keeps screaming at us til we wake up them continues even if we let him out. He eats good, he doesn't have irregular poop color, he doesn't gag or puke too. Is it new place stress or, is he bored. Is he anxious? Any ideas?
