ranking all planets in the cosmere objectively
Roshar: 3/10 no amount of native bird species, but there are still some from off world
Ashyn and Braize: 0/10 I’m lumping them together because they are in the rosharan system and have no birds and are horrible
Canticle: 0/10 this planet just. Completely sucks . Death world and no birds
Nalthis: 8/10 good amount of birds, have a lot of parrots and other beautiful avians, but no significant relevance for birds in nalthian culture
Lumar: 6/10 the primary mentioned presence of birds are seagulls (seagulls are still great tho) so the population/diversity seems limited
The Grand Apparatus: 3/10: it has Lawnarks which are not birds but are bird like so I’ll give it a consolation point. There could also be other birds but we have no idea
Vax, Dhatri, Bjendel, U’Tol, Obrodai and Mythos: idk???
Scadrial: 9/10 it’s supposed to be ecological similar to earth so that means that almost every bird on earth is on scadrial (at least post catacendre), and earth has a lot of awesome birds
Sel: 7/10 there are unique bird species mentioned (and more assumed to live there), but little actual worldbuilding goes into the birds
First of the Sun: 20/10: YOU KNOW THEM, YOU LOVE THEM, THE AVIAR ARE ***MAGIC*** BIRDS!!! BIRDS HAVE AN UNRAVILED IMPORTANCE ON FIRST OF THE SUN, SO ITS THE BEST PLANET IN THE COSMERE!!!! (also I know it’s the worms that are technically magical but the birds are the ones that do the things so it still couns)
Taldain: 2/10 dunno how many birds there are there but it’s likely there are at least some.
Komashi: 6/10 it would be way higher (BIG CROWS!!!) but I’m not sure how alive the birds are.
Threnody: 5/10 birds but not many or notable species :(
