Thank god, they haven't come to 5e, but the Raptorians: A Now Shut Up race to DMs with a fear of flying to offer as a 'compromise'. They get a sad glide ability and look absolutely stupid with weird bird feet and a racial weapon 'the foot bow', which is actually not useful due to how the glide ability worked.
Also they're a species with females who are the ISO standard slim-waisted waif who lay eggs. Eggs that are described in a way that one assume they shatter the mother's pelvis to be born.
Also space hippos for life, I say, good chap.
