The pelagornis is a great bird for collecting organic polymer off baby penguins primarily, They are all around a fantastic bird as they can land on water while low on stamina. While on the ground the pelagornis is rather slow but in the water it is very quick especially while utilising it's spring ability in water and it's ability to strafe from side to side as well. While landed their stamina drops rather slow while attacking making it easier to defend them on the ground or water if something is attacking you.
If you hate when your flyer dismounts becuase of it in water well this will fix it it can land and float on water and it doesn't dismount you at all very useful for pvp if your about to go underwater. Becuase a giant squid I cant spell the squids name tho anyways.
