The Gurgle-Gob is a fairly large species of bird native to Vogelheim. In terms of anatomy and general behavior, it bares a close resemblance to Earth's Turkey (but since Turkey as a country doesn't exist in its native world, the bird cannot be named after it).

Males of the species are slightly larger than the females and sport a beautiful coat of plumage, which they use for display during mating season. When the males want to perform and impress potential mates, they will puff up their feathers and, through the use of their elaborate throat sacks, will serenade their chosen females with a "symphony" of gurgles and "gobs" (hence their name) which will then culminate with what scholars describe as "the most ungodly sound ever heard"...
[ author side note: I actually have the exact sound they make: https://youtube.com/shorts/dfcDoTWn.....?feature=share ]
... when a whole group of male Gurgle-Gobs begins their symphony of "oh-god-why??!" the grasslands and forests they inhabit quickly empty of all life, as only the females of their species don't find this sound appalling.

Fortunately for the rest of the ecosystem (and the researchers) the Gurgle-Gob mating season lasts for only a few days each spring. For the rest of the year, these birds limit themselves to making simple, and much less horrid, gobbling sounds... unless confronted by a predator, in which case the males will then make a single "symphony finale" in order to stun their foe and then run away into the thicket as fast as their legs can carry them. Females rely mostly on their camouflage to evade danger.

After the mating season, the females will lay up to 10 eggs which they will sit on for about a month, taking shifts along with the males. The chicks are then reliant on their parents for about 4 months before they are big enough to fully fend for themselves.
