Swansea Uni study: African wild dogs 'sneeze to vote' (2017)

Given the extreme distances that some birds travel, it seems unlikely that each bird remembers the exact route, but maybe every bird remembers separate fragments. As a flock, they have a distributed memory of the whole migration path. They then vote on the best path by calling out constantly.
I looked a bit at the research, and it seems that they're probably using the sun/moon or magnetic fields to navigate. It's still a fun thought though.
I still wonder what's the purpose of the constant calling?
Maybe they are just having a good time.
I don't think that contradicts your hypothesis. Whether they're using magnetic fields, landmarks, the sun or sextants and chronometers, the question still remains of where they store their map. Does each bird store the entire map flawlessly in their head, or does the correct map without errors only exist collectively?
If they detect I'm about to go out, they start campaigning to go with by jumping around in front of me while I'm walking around gathering up my shoes or whatever, showing a lot of excitement. It frequently culminates in one or two sneezes.
I have started to suspect that it means something.

Most existing systems are robust to a failure case that's been happening regularly for tens of thousands of years.
It's cute as hell.
