Avianocene — Age of Birds

Avianocene — Age of Birds

In the late 21st century, humanity fought the greatest war in its history. As nations collapsed one by one beneath nuclear fire, cyberwarfare, famine, and ecological ruin, the losing powers enacted final retaliation protocols. Entire arsenals were released at once: atomic weapons, engineered plagues, autonomous weapons systems, atmospheric toxins. But among them all, one creation reshaped Earth more completely than any bomb.

The pathogen was called Eve's Silence.

Unlike earlier bioweapons, Eve’s Silence was not designed to kill. It targeted a highly conserved reproductive pathway found in placental mammals, disrupting embryonic implantation and causing universal infertility. Humanity was its intended victim—but humans were only one branch of the placental lineage. The disease spread rapidly through air, water, blood, livestock networks, and collapsing ecosystems, crossing species barriers with catastrophic ease. Within decades, birth rates among nearly all placental mammals fell to near zero.

Civilization did not vanish overnight. Humanity slowly aged into extinction over decades beneath darkened skies and poisoned oceans. Cities emptied. Forests reclaimed highways. Nuclear winters faded into greenhouse centuries. Most placental mammals disappeared alongside humanity: primates, rodents, whales, carnivores, ungulates. The only placental mammals to survive were bats; their strange immune systems gave them resistance to the plague.

Earth entered a new age.

Over the next two million years, reptiles spread once more across warming continents and flooded coastlines. Birds inherited the skies, the ruins, and eventually the ecological dominance once held by mammals. When most of New Zealand disappeared beneath the water, the alpine Keas spread across the world—not knowing they would become the ancestors of the world’s first avian intelligences.

This was the beginning of the Avianocene — the Age of Birds.

Keas evolved rapidly, gaining many new traits.

🧬 Biological Specifications (Avianocene Kea Descendants)

🧠 Systems-Oriented Cognition

These birds perceive the environment as a network of interacting systems rather than isolated objects. Decision-making is based on cause-and-effect relationships across weather, terrain, movement, and group behavior. Individuals tend to evaluate actions by predicted system outcomes rather than symbolic or moral reasoning. Keas are equally able to think about the abstract—but their conclusions are very likely to be logical and scientific. They have a very intelligent dispositon.

❤️ Emotional Intelligence and Attachment

They retain strong affiliative bonding and are fully capable of sustained emotional attachment, including long-term pair bonds, cooperative partnerships, and group loyalty. These bonds are reinforced through repeated coordination, shared experiences, and behavioral synchronization. Emotional connection is expressed through ritualized vocalization, coordinated movement, and mutual behavioral adaptation. Keas are able to feel the full palette of emotions, including love.

🧬 Divergent Excretory and Reproductive Anatomy

Unlike most modern birds, Avianocene Kea descendants have evolved partial separation of biological systems that were formerly unified in the cloaca. Waste elimination, urinary processing, and reproductive functions occur through distinct internal channels with separate external openings. This separation improves hygiene, reduces disease transmission in dense settlements, and allows more precise behavioral control of reproductive processes. No Kea species has "cloacas" anymore. As well as this, male Keas have evolved external penises and testicles.

Keas have become the dominant creature on Earth, inhabiating every corner. The different species are:

🏔️ Alpine Lineage
Psittasapiens altimontis
Casual name: High Keas
Location: High mountain ranges, alpine cliffs, and cold upland zones.
Description: Stocky, powerful parrots with dense plumage in muted greens and slate tones. Most similar to the original Keas.

🌿 Canopy / Forest Lineage
Psittasapiens cantori
Casual name: Song Keas
Location: Dense temperate and tropical forests, including settlement hubs like Tahl’Kera.
Description: Arboreal generalists that form large distributed forest settlements organized around tall central trees and canopy networks. They are the most cultured of any Kea species. Medium-sized, with highly diverse and vivid plumage patterns, often displaying striking combinations of greens, golds, blues, and warm earth tones; they are the most visually varied of all Kea lineages, with many populations showing locally distinct “aesthetic lineages” shaped by sexual selection, social preference, and cultural taste rather than pure environmental pressure.

🌊 Coastal / Oceanic Lineage
Psittasapiens pelagius
Casual name: Wave Keas
Location: Coastal cliffs, island chains, and ocean wind corridors.
Description: Slim, long-winged parrots with streamlined bodies and darker, salt-dulled plumage, shaped for sustained gliding along coastal winds and oceanic air currents.

🏜️ Desert Lineage
Psittasapiens arenicolis
Casual name: Sand Keas
Location: Arid deserts such as the Sahara, interior continental deserts, and dry basin systems.
Description: Pale, lightly feathered parrots with sand-and ochre-toned plumage. Elongated wings for heat dissipation.

❄️ Polar Lineage
Psittasapiens borealis
Casual name: Ice Keas
Location: Arctic and Antarctic regions including Siberia, Greenland, Canada, Norway, Finland, and Antarctica.
Description: Large, heavily feathered parrots with thick insulating plumage in white, blue-gray, and light blue tones. These are strikingly beautiful birds.

One particular settlement is called Tahl’Kera.

Tahl’Kera is a forest-rooted settlement anchored within an ancient emergent tree at the center of a dense, temperate woodland. It is not a city in the human sense, but a distributed ecological system of habitation, communication, and memory. The settlement spans a network of interconnected trees and canopy pathways, with a central “Heart Tree” acting as its acoustic, social, and structural anchor. From this core, life radiates outward into surrounding trunks, branches, and forest corridors, forming a layered habitation zone rather than a fixed boundary.

At its center, the Heart Tree has been shaped over generations by Kea-descended intelligences into a vast internal hollow system. Bone tools and hardened beaks have carved resonance chambers within its trunk, where sound is shaped and returned with precision. These chambers are used for large-scale coordination events, environmental modeling through collective vocalization, and the stabilization of shared behavioral patterns. Around and above this internal core, external structures of woven fiber, resin, and shaped wood extend along the canopy, forming nesting clusters, wind-guiding nets, and aerial pathways that regulate movement and communication across the settlement.

The population of Tahl’Kera consists of approximately four to five thousand Kea-descended individuals, primarily of the canopy-adapted lineage (Psittasapiens cantori). Life here is highly distributed: only a fraction of the population resides within the central tree at any given time, while the rest are spread across surrounding canopy nodes and forest extensions. Movement between these zones is continuous and fluid, governed not by ownership or fixed territory, but by shifting social alignment, ecological conditions, and resonance-based coordination systems.

Daily life within Tahl’Kera is structured around cycles of environmental calibration rather than fixed schedules. Groups engage in coordinated flight patterns, vocal exchanges, and shared foraging circuits that continuously refine understanding of wind, weather, and ecological change. The settlement functions less as a place of residence than as a living system, where structure, memory, and perception are distributed across both biology and landscape.

Tahl’Kera is a forest settlement built around a single massive emergent tree at the center of a dense woodland. The tree serves as the main gathering and communication point, while most of the population lives across surrounding trees connected by regular flight paths. These trees form a loose network of nesting and activity sites rather than a single enclosed structure.

Inside the central tree, large hollow chambers have been carved over generations using bone tools and hardened beaks. These spaces are used for communication events, decision-making, and rest. The hollows are shaped to carry sound clearly through the trunk, allowing vocal signals to reach large groups at once. Outside the trunk, woven fiber platforms, resin bindings, and wooden supports extend along major branches, forming stable nesting areas and movement routes.

The settlement population is approximately 4,000–5,000 individuals, mostly Song Keas (Psittasapiens cantori descendants). Only a small portion live inside the central tree at any time; most are spread through nearby trees within several kilometers. Individuals move frequently between sites throughout the day, following established flight corridors and seasonal foraging routes.

Life in Tahl’Kera is organized around repeated group activities. At certain times, flocks gather in specific hollow chambers for coordinated vocal exchanges used to share information about weather, food locations, and movement routes. At other times, smaller groups travel outward to forage or maintain nesting structures. There is no fixed leadership; individuals who demonstrate accurate environmental prediction or successful navigation temporarily guide group movement, but this changes regularly.

Tahl’Kera functions as a single settlement spread across many trees, held together by repeated movement, shared communication, and constant interaction rather than permanent enclosure or centralized control.
