Aigle est l’une des vingt-quatre espèces de cet atlas. Ce n’est pas un catalogue : évolution, anatomie, comportement, culture, icônes, conservation et aire forment un seul système.
Les scores comparent vitesse, intelligence, aire, résilience, impact culturel et rôle écologique. Ce sont des jugements éditoriaux relatifs, pas un classement de laboratoire.
Sept chapitres creusent : origines, corps et sens, vie et comportement, culture, icônes, pression de conservation et l’aire partagée avec les gens.
Introduction profonde
Deep dive: Aigle
Aigle is not a single postcard animal. It is a set of populations, subspecies and human rules inside the birds family of this atlas.
Diversité, corps, culture et aires — plus une lentille de cette région linguistique.
Diversity inside the type
Field guides collapse many lineages into the English word Aigle. Subspecies, flyways and captive lines do not share one fate -- bald eagles and Philippine eagles, or western and mountain gorillas, are the caution.
This atlas picks a Wikipedia title as the hero image and then keeps the rest of the grade in view so a recovered stock cannot launder a CR cousin.
Life in the landscape
A fused carpometacarpus, large ungual talons and a hooked bill define the killing kit. Sea eagles add a heavier tarsus for fish; booted eagles add feathered tarsi for cold and mammal prey.
Sit-and-wait on a commanding perch, then a short powered chase or a long stoop. Kleptoparasitism on ospreys saves hunt energy on salmon rivers.
Culture and meaning
English-language culture met the Aigle through film, law, heraldry and zoos. Those portrayals move money and sometimes take; they are not a field census.
The culture chapter dates posters and statutes so a 1975 film or a 1961 logo cannot pretend to be a 2020s Red List.
Conservation and money
Bald Aigle recovered to Least Concern after 2007 delisting; Philippine Aigle remains Critically Endangered.
Tourism, conflict payments, quotas and captive loans are dated economic bands in the market chapter -- not live prices and not a best-species prize.
Plongée sciences de la vie
Biology deep dive: Aigle
Aigle biology is a stack of structure, energy, sensing and hard limits. The four sections below are the same headings used across the atlas so types can be compared without a best-species frame.
Anatomie, sens, comportement et limites — plus le langage de terrain de cette région.
Structure
A fused carpometacarpus, large ungual talons and a hooked bill define the killing kit. Sea eagles add a heavier tarsus for fish; booted eagles add feathered tarsi for cold and mammal prey.
Load paths and tissues (not metals) are expanded in the anatomy chapter.
Energy and foraging
Sit-and-wait on a commanding perch, then a short powered chase or a long stoop. Kleptoparasitism on ospreys saves hunt energy on salmon rivers.
The how-it-works diagrams reduce that budget to a six-node loop.
Senses and control
A fovea dense with cone cells supports high-acuity prey detection at distance. Oil droplets and a pecten oculi are the usual avian optical extras.
Control here means the animal steering itself -- not a vehicle ECU.
Limits
Wing loading limits closed-canopy pursuit. Lead, rodenticides and turbine blades are modern ceilings that talons cannot solve.
Resilience scores encode those limits relative to the other 23 types.
Four other atlas types, six terms, three threads and three local notes -- a map out of the Aigle page without leaving the 24-id taxonomy.

Termes clés
Stoop
High-speed dive with wings folded — golden eagles have been timed above 240 km/h in trained flights.
Aquila
Genus of “true eagles” — golden, imperial and wedge-tailed lineages.
Haliaeetus
Sea-Aigle genus — bald, white-tailed and Steller’s — often fish-first.
Eyries
Cliff or super-canopy nests reused for decades; some exceed two metres across.
Kleptoparasitism
Food theft — bald eagles routinely rob ospreys on salmon rivers.
DDT eggshell thinning
1960s–70s collapse mechanism reversed after the 1972 US DDT ban.
Habitat and movement
Where the Aigle breeds and feeds is the first constraint. Single lakes, islands and forests appear again in the history timeline.
Range scores in this atlas mark how widely that movement runs -- albatross and blue whale high, koi and panda low -- not a quality ranking.
Research and law
Named projects (Project Tiger, ACAP, ICCAT, Amboseli) are the English-language bureaucracy of the type.
Listings and downlists are dated events in the timeline, not eternal essences.
Culture and price
Film, auction and logo years are filed under culture and market so they cannot masquerade as demography.
The icons chapter keeps eight real Wikipedia titles so a later language pack can attach the same faces.
