Can easily over encumber itself gathering organic polymer. However, using a quetzal as a carrier of both the animal and the polymer can allow for very successful polymer runs. Sometimes bringing in excess of 1000 in a hour run on an island server.
Once upon a time Pelagro was bullied in school for being a figure skater. The antagonistic Rex proclaimed "Anywhere, anytime dweeb!". So, Pelagro suggested the bully tried to fight Pelagro on ice, where he was very suddenly outmaneuvered, and Pelagro kicked Rex's butt. Point is, if you're using this thing to kill fish, you've only scratched the surface. Capable of killing any land bully if close to deep water.
They're great at clearing out pirhana infested waters, since pirhanas will go right up to it but then make a quick 180 when they realize what you're riding, and you kill them in one shot. Great for clearing out swamps, just be mindful of all the other monsters there, especially kapro's
The pelagornis can be very useful for helping get players or dinos across piranha infested waters. Since they do 10X more damage to piranhas, coels, and salmon, they can be used to clear out swarms of them in rivers or swamps. You can then safely cross the water without needing to worry about piranhas killing your friends or dinos. Make sure to be aware of other dangers in the water such as sarcos, spinos or megalodon.
Tip: Since it farms alot of Organic Polymer, I built a small base on an Iceberg where the penguins are and I leave it there so whenever I need Polymer, I just go travel to the base with an Argie and take the seagull out!
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.
