Horned Screamer (Anhima cornuta)

"The fact that the universe saw fit to let this thing exist" "horn, prominent spurs on wings, "The most peculiar feature of the screamers is a skin filled with small bubbles of air about a quarter of an inch thick, which produce a crackling sound when pressed; the function of this layer of air bubbles is unknown.""

Hey these guys are ducks! No I'm not lying- they're ducks! They belong to the same order as ducks, geese, and swans! What the fuck!

While my surface level digging did not confirm this, my thought is that screamers represent a branch in anseriformes where the ducks had recently split from gamebirds in galliformes, but hadnt yet specialized to have their spatulate bills. I'm not a source to quote on this though, as the paleontological record is a bit hazy for screamers.

For some actual facts: their horn is not a modified feather or something adjacent, but is "a cornified structure loosely attached to the skull, which frequently breaks off at the tip." They eat water plants but only have partially webbed feet. They have wing spurs. Despite being 8lb (3.5kg) birds, they nest on floating vegetation. What the heck is going on with these guys??

. Nome Popular: Tachã English Name: Southern Screamer Família / Family: Anhimidae Nome Científico: Chauna torquata Mede cerca de 80cm de comprimento e pesa cerca de 4Kg. De coloração pardo-acinzentada escura, com algumas manchas brancas, cabeçuda e topetuda. O pescoço é contornado por uma gola negra realçada por uma segunda penugem branca. A face superior da asa é negra, com grande área branca visível durante o vôo, a face inferior da asa é totalmente branca. Região perioftálmica, anel nu ao redor do pescoço (nem sempre visível), pernas são vermelhas. Não há dimorfismo sexual, as fêmeas são menores que os machos. As patas são curtas e fortes e os três dedos da frente estão unidos por uma membrana interdigital rudimentar. Grande habitante dos brejos, com formato e características únicas. O corpo, pernas e pés são enormes em relação à cabeça, pequena e com um penacho na nuca. Em vôo, mostra uma grande área branca sob a asa. Possui um esporão vermelho no cotovelo da asa, visível quando está pousada ou voando. Apesar do aspecto agressivo, não é usado como arma de ataque, servindo para comunicação entre as tachãs. Alimenta-se, principalmente, de folhas de plantas aquáticas, apanhadas enquanto caminha pelo brejo ou nas margens, assim como insetos e moluscos. É monogâmica e territorialista. Pousa nas praias ou nas árvores da mata ribeirinha. Constrói um enorme ninho de folhas emaranhadas sobre um arbusto ou árvore pequena, sempre sobre a água. Coloca de 2 a 7 ovos, chocados durante cerca de 45 dias. Geralmente o macho passa mais tempo chocando os ovos, revezando com a fêmea quando precisar se alimentar mas nunca deixam o ninho sozinho. Os filhotes saem do ninho logo depois de nascerem ou no dia seguinte, cobertos com penugem semelhante a dos patinhos. Caminham com os pais, ficando imóveis e escondidos na vegetação ao primeiro grito de alerta. Os juvenis recebem os cuidados parentais de ambos os progenitores durante 3 a 4 meses. Por volta dos 5 meses completam a plumagem e podem voar. . . . . . . #wildbird #feather_perfection #birdlove #wildbirds #bird_watchers_daily #birdslover #bird_brillance #birds_of_ig #birdsofinstagram #cutebirds #birdart #cuiabá #cuiaba (em Cuiabá, Brazil) https://www.instagram.com/p/CkwaHmsvO6R/?igshid=NGJjMDIxMWI=

Southern Screamer (Chauna torquata), family Anhimidae, order Anseriformes, found in wetlands in central South America

Mainly herbivorous waterfowl, in the same order as ducks and geese, but in a different family.

Screamers prefer to walk/wade through their habitats, instead of swimming. They can swim, but are not as proficient as ducks and geese.

How did I not know this bird existed?

It’s a wetlands bird endemic to tropical South America. What makes it unique, is that it grows a bony cornified (keratinized) spike from it’s head, which frequently breaks and regrows, and it has a spur used for fighting, growing out of each wing.

The horned screamer is a massive 84–95 cm (33–37.5 in) long, 3.5 kg (7.7 lb) bird, with a small chicken-like bill. The upper parts, head, and breast are black, with white speckles on the crown, throat and wing coverts.

There is a long spiny structure projecting forward from the crown. This structure is unique among birds and is not derived from a feather but is a structure that is loosely attached to the skull and grows continuously. This gives this species its ‘horned’ name.

It has very long and lanky legs and three large toes in each. The belly and under wing coverts are white. It has two sharp spurs on its wings and feet which are only partially webbed.

The horned screamer's call, as its name suggests, is a very loud echoing sound. source
