Feather Family extinct birds represent the highest-tier unlockable species in the Roblox bird roleplay game created by The Feather Family. Introduced primarily through recurring Summer of Fossils updates and the Ice Mountain Fossil Lab, these prehistoric avians and feathered dinosaurs range from small Mesozoic fliers to massive flightless predators. Unlocking them requires saving in-game Feathers, which players accumulate passively during standard gameplay.

Complete List of Extinct Birds and Feather Costs

Extinct birds in Feather Family make up the unlockable roster priced at 1,000 Feathers and above. In the bird selection menu, standard prehistoric birds are designated with brown nameplates and bone icons, while top-tier exceptions such as Dromaeosaur, Skeleton, and Robot feature yellow nameplates marked with stars.

Summer of Fossils Events and Lab Lore

Extinct birds entered Feather Family through biennial "Summer of Fossils" events. According to official developer Q&A notes, these updates run on a two-year schedule, with past editions debuting in 2020, 2022, 2023, and 2025, and the next installment planned for June 2027.

The narrative centerpiece of these updates is the Fossil Lab inside Ice Mountain. In the game's background lore, Dr. Penguin refurbished an abandoned human laboratory to resurrect extinct species:

  1. The Early Experiments (2020): Dr. Penguin successfully revived initial species including the Dodo, Archaeopteryx, Moa, Kelenken, Pelagornis, and Argentavis. However, a catastrophic miscalculation led to the creation of the monstrous Skeleton, causing Dr. Penguin to flee out of guilt and leave behind research journals.
  2. Penguin Jr.'s Expansion (2022): Penguin Jr. remodeled the lab, requiring players to input a keycode to study new specimens like Confuciusornis, Hesperornis, Gastornis, and Harpagornis.
  3. The Father-Son Reunion (2023–2025): Dr. Penguin returned to work alongside his son, adding rows of incubation tubes and uncovering species such as 'Ō'ō, Elephant Bird, Kumimanu, Dromornis, and dromaeosaurid dinosaurs.

Players can visit the Fossil Lab directly by selecting the Fossil Lab teleport destination. Accessing the interior requires entering a randomized keypad code discovered on tablets scattered near the lab entrance.

Distinct Gameplay Mechanics and Species Traits

Extinct birds feature specialized movement systems and interactive behaviors that separate them from modern avians in Feather Family.

Superprecocial Flight Mechanics

Certain early avialans and dromaeosaurs hatch with superprecocial abilities. Unlike standard chicks that must grow into adults to fly, hatchlings of Confuciusornis, Jeholornis, Sapeornis, Falcatakely, Feitianius, Microraptor, and updated Archaeopteryx can take flight for a brief duration before needing to rest on the ground.

Tail Physics and Climbing

The August 2025 update introduced dynamic tail physics. Long-tailed species, particularly members of the Dromaeosaur line like Velociraptor and Microraptor, possess trailing tail feathers that react fluidly to character turns and sprint movement. Additionally, climbing-capable species with clawed wing limbs can latch onto vertical surfaces and tree trunks automatically when landing against them.

Aquatic Propulsion

The giant penguin Kumimanu features unique swim and land animations. On solid ground, its sprinting action initiates a belly slide. In deep water, Kumimanu possesses enhanced jumping velocity, allowing it to breach high above the surface like modern marine animals when holding the jump control.

How to Unlock Prehistoric Birds

All extinct birds except event-exclusive skins are permanently available in the in-game bird catalog. They do not require real-money Robux or game passes.

  1. Earn Feathers Through Playtime: Feathers generate automatically at a rate of 5 Feathers every 90 seconds of active play.
  2. Monitor Your Currency Cap: The standard wallet limit allows players to hold up to 10,000 Feathers at one time.
  3. Purchase from the Feather Shop: Open the bird catalog or click the in-game Feather icon to open the unlockable shop. Navigate down past the modern standard birds to select your desired prehistoric bird.
  4. Choose Skins and Realism Presets: Species containing multiple variants—such as Dromaeosaur (offering Microraptor, Deinonychus, and Velociraptor) or Skeleton (offering Harpagornis and Archaeopteryx)—allow you to pick your preferred model right from the spawn prompt.

Frequently Asked Questions

Which extinct bird is the most expensive in Feather Family?

Excluding the mechanical Robot bird (5,000 Feathers), the highest-priced prehistoric creatures are the Skeleton at 4,000 Feathers and the Dromaeosaur family at 3,000 Feathers. Among pure avian species, the Argentavis costs 2,000 Feathers.

Can all extinct birds fly?

No. Several prehistoric birds are entirely flightless, including the Dodo, Moa, Elephant Bird, Kumimanu, Dromornis, Gastornis, and Kelenken. Basal avians like Archaeopteryx feature limited flight and glide downwards when their flight duration expires.

When is the next Summer of Fossils update?

According to developer goldenaviary in the 2026 Q&A bulletin, Summer of Fossils operates on a two-year cycle. Following the 2025 event, the next Summer of Fossils is scheduled to launch in June 2027.
