Animal answers — FAQ across every species

The white head and tail typically appear after four to five years. Juveniles are mottled brown, which reduced historical miscounts in winter surveys.

Level cruising for large eagles is often 50–80 km/h. A hunting stoop is a different regime — trained golden eagles have been filmed above 240 km/h.

By 1963 the lower-48 count was about 417 nesting pairs. The 1972 DDT ban plus Endangered Species Act protection preceded the 2007 delisting.

No. “Eagle” is a grade inside Accipitridae. Sea eagles (Haliaeetus) and booted eagles (Aquila) split tens of millions of years ago.

Pithecophaga jefferyi is a forest-interior endemic with perhaps a few hundred adults. Logging and shooting, not eggshell thinning, dominate the threat list.

Many pairs are socially monogamous and reuse eyries, but extra-pair behaviour and mate replacement after nest failure are documented.

Fish, seabirds and carrion dominate. Isle of Mull and Isle of Wight releases (from 1975 and 2019 programmes) track sheep-loss complaints against actual diet data.

Breeding spans Alaska to northern Mexico and both coasts of Canada. The US recovery is the famous chapter, not the whole range.

Barn owls can strike by hearing alone. Asymmetric ear openings give elevation; the facial disc gives azimuth. Vision still matters in starlight.

The velvet and comb are strongest in forest nocturnal hunters. Fish owls and some burrowing species are noisier — water and day hunting change the trade.

Corvids and parrots outscore owls on many lab tasks. The “wise owl” is Athena’s bird, not a working-memory ranking.

Hedwig is Bubo scandiacus, an Arctic lemming specialist. The films made a tundra bird the global pet-owl image — and briefly spiked illegal trade.

Tyto alba can lay 2–12 eggs when vole cycles peak. Nest-box programmes in UK barns track that boom-bust directly.

Ketupa blakistoni is Endangered. Riparian old growth in Hokkaido and the Russian Far East is the binding constraint.

About 270 degrees, not 360. Extra cervical vertebrae and vascular loops keep blood flowing during the twist.

Yes. Street lighting, park voles and road mortality now shape Strix aluco densities in European cities as much as woodland area.

No. Galápagos penguins breed on the equator. African penguins nest on Namibian and South African islands. Antarctica holds the emperors and Adélies, not the whole family.

Tagged emperors have exceeded 500 m and stayed down more than 20 minutes. That is a seal-like performance on a bird lung.

Luc Jacquet’s 2005 film made Aptenodytes forsteri a global winter story. Scientists later argued the narration over-moralised a physiological commute.

About 19,000 African penguins were oiled near Cape Town. SANCCOB and volunteers ran one of the largest bird-rehab operations recorded.

The tight thermoregulatory huddle is an emperor (and some king) story. Burrowing little penguins and tree-nesting gentoos use different heat tricks.

Yes on a decadal clock. Purse-seine competition and shifting sardine/anchovy biomass cut South African colonies by large fractions since the 1950s peak.

Salt glands above the eye dump NaCl as a concentrated drip from the bill — the same avian gadget albatrosses use.

Erect-crested and others depend on stable subantarctic fisheries and nest sites. Mice on Gough and other islands add a predation problem flightless birds cannot fly away from.

The shoulder allows a nearly horizontal figure-eight. Lift on the upstroke as well as the downstroke pays the hover bill that a typical avian stroke cannot.

No. Nectar is fuel. Arthropods supply protein, especially for chicks. Feeders that omit insects do not replace a territory.

Ruby-throated hummingbirds fatten, then fly 800+ km nonstop. Tailwinds and a high mass-specific power output make the crossing possible, not a rest on ships.

A controlled drop in body temperature and metabolic rate overnight. Without it, many species would exhaust nectar stores before sunrise.

Diversity peaks in the Andes. Anna’s hummingbirds now winter in Vancouver gardens; ruby-throated breed to southern Canada.

John Gould’s 19th-century monographs and skins made trochilids a Victorian craze — with a collecting cost that modern field work still cites.

Sword-billed hummingbirds match 10–14 cm bills to Datura and Passiflora corollas — a coevolution exhibit, not an ornament.

Feeders help watchers and some urban birds. Habitat corridors and native tubular plants decide whether migrants still find the Gulf’s far shore.

Dietary carotenoids from brine shrimp and cyanobacteria deposit in feathers. A white flamingo is usually a diet or age story, not a different species.

The bird feeds with the head inverted. The upper jaw is the mobile filter; lamellae comb a soup of algae and invertebrates.

Yes. Phoeniconaias minor can number more than a million on Rift soda lakes when Arthrospira blooms. Breeding still hinges on sites like Lake Natron.

Salt pans and Tour du Valat management rebuilt a greater flamingo colony that now seeds Mediterranean satellites.

A breeding population has returned to Florida Bay after a long absence. Some birds are escapees; others are wild Caribbean wanderers — the mix is a current field argument.

High-Andean salars face lithium and water extraction. Three highland species share a small set of lakes.

They use salt glands and fresh seeps. Chicks on soda lakes need adult crop milk and freshwater access.

Union Products’ 1957 pink flamingo (Don Featherstone) is culture, not field mark — but it fixed the colour in US suburbia more firmly than field guides did.

Irene Pepperberg’s papers treated English tokens as categories, not circus tricks. Alex (1976–2007) identified colours, shapes and same/different above chance. The debate is about the ceiling, not whether the tasks happened.

Wild capture for pets plus forest loss cut Psittacus erithacus. Appendix I ended most commercial international trade in wild greys.

Every Strigops is named and managed on predator-free New Zealand islands. Supplementary feeding and nest cameras make it closer to intensive care than to a hands-off reserve.

They are an introduced boom, not a restored native. Cavity competition with starlings and bats is the local argument.

Cavity trees come down with forest. The pet trade added a second cut. Spix’s macaw went extinct in the wild before a 2019–20s reintroduction attempt in Bahia.

They learn contact calls in flocks. Human-word mimicry is the lab and living-room version of a general vocal-learning kit shared with songbirds and hummingbirds.

Since 1989 it funded trade research, in-situ projects and the journal PsittaScene — a counterweight to avicultural magazines.

Kea pry, lories brush nectar, and hyacinth macaws crack palm nuts. The bill is a Swiss-army kinetic tool, not a single nutcracker.

The bird climbs and dives through wind-speed gradients above waves, converting shear into airspeed. Heart-rate loggers show travel costs closer to rest than to flapping flight.

A female banded in 1956 by Chandler Robbins at Midway. She has fledged chicks into her seventh decade — a longevity record that made a single band number famous.

Baited hooks look like squid. One set can kill dozens of birds. Night setting, weighted lines and tori lines cut the kill when fleets actually use them.

The 1798 Rime made killing an albatross a moral crime. The poem outran the biology and still titles newspaper bycatch stories.

The northern royal albatross colony near Dunedin is a mainland breeding site with public hides — rare for a family that usually needs remote islands.

On Gough and some other islands, introduced house mice attack chicks of albatrosses and petrels. Eradication attempts are now as central as hook rules.

The atoll is also the world’s largest Laysan albatross colony. Plastic and lead paint joined the WWII ruins as management files.

BirdLife assessments have long placed a majority of Diomedeidae in threatened categories — an unusual concentration for a small family.

The taxonomy hero is Grus japonensis -- Kushiro, the Korean DMZ and Izumi. Other Grus species appear as comparison, not as the page type.

The Aransas-Wood Buffalo flock was about 21 birds in 1941. That nadir still defines US recovery graphs.

He courtship-danced with a human-imprinted whooping crane named Tex so she would ovulate -- a 1980s method story, not a field census.

A large share of the migratory island population winters on one Kyushu floodplain. Influenza years there are species-level events.

Pairs are typically socially monogamous. The dance is pair-bond and territorial display, not a fairy-tale wedding.

Wintering red-crowned and white-naped cranes use the Civilian Control Zone. Peace-time development is a documented risk to that accidental reserve.

Chicks imprint on humans and then fail to migrate or pair. Operation Migration ultralights (2001-2015) tried to teach a new flyway.

No. The resident Kushiro group and mainland migratory birds are one species with different movement strategies.

The 1975 film increased trophy interest and beach fear. Later decline drivers are fins, bycatch and slow life history. Benchley later argued the fiction had been taken as a brief.

A mid-Pacific patch where California-tagged whites linger. Foraging on midwater squid and fish is the working hypothesis, not a seal colony.

They are regional endotherms. Countercurrent heat exchangers keep muscle and stomach above ambient -- not mammalian homeothermy.

Cape fur seals and elephant seals create predictable prey. Cage tourism and research boats stacked on those same reefs.

A very large female photographed at Guadalupe and later Hawaii -- a media name, not a stock assessment.

Appendix II in 2004. Papers still move; the listing forces permits and data, not a zero quota.

Many coastal adults make basin-scale loops (California-Cafe-Hawaii). Site fidelity to seal colonies is seasonal.

Cape Cod and parts of California show more sightings as grey seals rebounded. Sightings are not a global Vulnerable reversal.

Most Oncorhynchus (Pacific) are semelparous. Salmo salar can spawn more than once. The postcard of corpses on gravel is a Pacific-weighted image.

Isotope studies show marine nitrogen in riparian trees and songbirds. Bears and eagles are the visible vectors; the trees keep the receipt.

After 2011-14, sediment flushed and salmon recolonised reaches above the old dams faster than some models feared -- a rare full-height teardown.

They keep harvest numbers up and can dilute wild fitness. The argument is now about proportions, not existence.

Wild S. salar collapsed in much of Europe and New England. Farmed Atlantic salmon in net pens are a separate industry with sea-louse and escape files.

Many Alaska runs are still large and limited-entry managed. That success is not transferable to a heavily dammed Columbia without the same habitat.

Olfactory imprinting on natal water plus celestial and magnetic cues. A ladder that smells wrong is a closed door.

US v. Washington affirmed treaty harvest shares for tribes. Allocation, not biology, became the daily salmon fight in Puget Sound.

No. First-sale theatrics at Tsukiji/Toyosu are marketing. ICCAT indices and spawning-stock biomass are the management numbers.

Eastern Atlantic/Mediterranean quotas and enforcement improved some indices after a crash. Recovered is a press word; scientists speak in probabilities and two stocks.

Purse seines catch live fish for fattening cages. It can hide juvenile take inside a farmed label.

Song for the Blue Ocean (1997) and later essays treated giant tuna as a governance failure, not a recipe.

Thunnus orientalis is a different species under WCPFC/IATTC math. The sushi case looks identical; the commissions do not.

Burst speeds exceed 60 km/h. Regional endothermy lets the fish hunt in colder water than most tunas.

Monterey Bay Aquarium cards made bluefin a red-list menu item in US restaurants long before some stocks ticked up.

Western stock spawning in the Gulf remains a closed-area and oil-spill argument after 2010 Deepwater Horizon papers.

Pixar Nemo is styled on Amphiprion ocellaris (this atlas type). Shops still mix ocellaris and percula under one common name.

A group is a female, a breeding male and non-breeders. If the female dies, the male changes sex. The film missing-mother plot skipped that rule.

Several trade analyses reported a demand spike after 2003. Captive-bred ocellaris later absorbed much of the legal market in the US and EU.

The fish mucus lacks the cues that trigger nematocysts, and acclimation behaviour matters. It is not a cartoon handshake.

Fish may linger on a dying anemone and then vanish from that site. Reef heatwaves are a housing crisis for the genus.

Males tend the nest of demersal eggs. The biology is paternal care, not a transoceanic search.

Eastern Indian and western Pacific reefs -- Andaman to the Philippines and Australia north -- not a Sydney Harbour suburban anemone.

Captive-bred ocellaris cut some wild take. It does not rebuild bleached hosts or stop cyanide fishing of other reef species sold beside them.

Yes. The female deposits eggs in the male pouch. He osmoregulates and nourishes the clutch until a miniature hatch.

A conservation-research group led by Amanda Vincent that supplied much of the CITES and bycatch evidence from the 1990s onward.

Documented international trade in dried and live animals met a genus that is sparse, site-faithful and easy to over-collect.

By volume, dried medicine and curio shipments plus trawl bycatch outweigh hobby live fish in most analyses.

Some live-hobby demand is captive-bred. Dried-trade volume and trawl bycatch are not solved by a hatchery SKU.

A rigid bony plate body and a dorsal fin that buzzes rather than a caudal fluke. Camouflage replaces flight.

Many pair; some do not. Daily greeting dances are real in several species and over-generalised in documentaries.

Seagrass die-off, mangrove fill and coral damage remove holdfasts. A CITES permit cannot grow a meadow.

No. Goldfish descend from Prussian carp (Carassius). Koi are ornamental common carp (Cyprinus carpio) fixed in Niigata. The atlas seeAlso cannot point at goldfish because that id is not in the taxonomy.

Colour mutants were kept in Yamakoshi rice-terrace ponds in the early 1800s. The 1914 Tokyo Taisho exhibition took them national.

The ZNA-centred championship that still sets kohaku, sanke and showa as the Gosanke core classes.

After the 1960s export boom, Israeli and US growers scaled food-and-ornamental carp. Butterfly fins are largely a non-Niigata aesthetic.

Koi herpesvirus outbreaks from the late 1990s killed whole collections. Quarantine and certified-free stock became the new entry ticket.

Common carp are invasive in many rivers and lakes. A show pond is secure; a flood overflow is not a garden anymore.

Giverny water lilies host carp in the public mind. The nishikigoi fancy is Japanese; the Impressionist pond is a later cross-reading.

The ornamental lineage is mass-bred and not Red-Listed. High resilience here means secure stock, not ecological innocence.

No. Toxin load varies by species, organ and season. Licensed fugu service still treats liver as forbidden in many prefectures after historic poisonings.

A compact genome (about 400 Mb) made it a 2002 model in Nature -- a puffer as a human-genome shortcut, not a menu story.

The fish gulps water into a specialised stomach diverticulum. Spines (in some species) erect. It is a mechanical jam, not a bluff only.

Much evidence points to bacterial and food-chain accumulation. Captive-raised puffers can be far less toxic -- a husbandry fact that complicates folklore.

Japan requires training and exams after 20th-century restaurant deaths. The licence is a public-health instrument, not a gourmet badge.

Hobbyists keep freshwater and brackish tetraodontids (e.g. figure-eight, Mbu). They share the beak and inflate; they are not all Takifugu.

Four fused tooth plates continuously grow and must be worn on hard prey -- a dental bill, not a cartoon.

Many coastal species are Least Concern; some endemics and heavily fished Takifugu stocks are not. Resilience here is mid-pack, not a free pass.

No. It is a gymnotiform knifefish. The body plan and voltage organ are South American, not Anguilliform.

A 2019 Nature Communications paper split Electrophorus into three: E. electricus, E. voltai and E. varii. Voltage and DNA both argued for the split.

E. voltai has been measured near 860 V. That is a prey-stun and defence pulse, not a household-current analogy that holds in every tank.

His account of horses herded into a pool of eels became a European science anecdote. Later readers treated it as a method; it was also travel theatre.

Volta and Galvani debates used animal electricity. Electrophorus was a New World exhibit in that argument, not the sole inventor of the pile.

A high-voltage volley can freeze prey; a weaker field maps the night water. Kenneth Catania high-speed videos in the 2010s showed doublets that twitch hidden fish.

No. LC reflects a wide Amazon-Orinoco footprint. Dams, drought and capture are local, not a comic-book immunity.

Captive voltage and diet differ. Field E. voltai numbers should not be read off a pet-shop tube.

Global estimates in the 2020s sit near 4,000-5,500 depending on the year and method. India holds the majority. The number is a camera-trap product, not a Victorian hunter tale.

India wild counts rose from a 1970s crisis to the largest national population. Methods changed (pugmarks to cameras), so the graph is not a single instrument. Southeast Asia did not copy the rebound.

A 2010 pledge by tiger-range states in St Petersburg to double wild numbers by 2022. Some countries gained; others lost. The slogan outlived the deadline.

Lions are Vulnerable with a wider African footprint and a tiny Gir relic. Tigers are Endangered, more forest-bound, and culturally heavier in South and East Asia. Scores stay relative across all 24 types.

A hunter of man-eaters who wrote Man-Eaters of Kumaon (1944) and later lent his name to India first national park -- a colonial-to-reserve arc.

Panthera tigris tigris now lumps many mainland tigers in some taxonomies; Amur animals still have a Russian-Chinese border programme and a different prey winter.

Wild P. t. amoyensis is considered extinct or functionally so. Captive Chinese lines are a genetic and political argument, not a forest population.

Project Tiger ideology said yes. Buffer people and corridor science later complicated the fortress model without dropping the core idea.

Lions structure some savanna systems; elephants and wolves outrank both as engineers or keystones in this atlas. Culture is flags, churches and film -- lions win that axis. Scores stay relative across 24 types.

Asiatic lions are a single-forest population with a distinctive belly fold and a thinner mane. A disease or fire there is a subspecies event.

The 2015 Hwange killing spiked petitions and some airline trophy bans. Zimbabwe and US Fish and Wildlife arguments did not end trophy hunting as a system.

No. Most African populations are still in long decline outside a few well-funded parks. VU is not a rebound band.

Elsa the lioness (1960 book, 1966 film) made rehabilitation a children story. Field lion work is pride demography and conflict, not a single tame cat.

The Serengeti Lion Project (Packer and successors) produced the long pride dataset that textbooks still mine.

1898 bridge-camp killings were a specific railway-and-drought story. They are a genre, not a base rate.

Males take large prey and cubs of rivals. The postcard male-on-a-rock is a coalition politics, not a lazy king.

The taxonomy wiki is African bush elephant. Forest elephants (L. cyclotis) were widely recognised as a separate EN/CR story in the 2021 IUCN assessments.

It collapsed legal international commercial trade. Domestic markets, stockpiles and later one-off sales (2008) kept the argument alive. Poaching did not end in 1989.

Amboseli Elephant Research Project since 1972 -- matrilines with names and decades of calves, the opposite of an anonymous ivory graph.

They open woodland, dig water, disperse seeds and rewrite fire. In this 24-type atlas that engineer role outranks even wolves and whales.

A periodic male state with urine dribble, temporal secretion and aggression. It is physiology, not a mood.

Large-scale culling paused in the 1990s. Contraception, range expansion and later density debates replaced it without a final peace.

Local highs (Chobe, parts of Kruger) sit beside collapsed miombo and Sahel populations. EN is a continental mean, not a waterhole photo.

Elephant Voices work on rumble communication and later musth and de-tusking ethics -- a second Amboseli-adjacent science.

Global LC hides Mexican wolves, some European growing pains, and US delisting fights. Resilience here is mid-high because many Holarctic populations rebounded -- not because conflict ended.

Fourteen wolves from Canada were released (more in 1996). Elk behaviour and riparian vegetation became a long argument, not a cartoon instant forest.

Early popular accounts over-simplified. Later work kept wolves important and added drought, human hunting, and beaver. The cascade is a research programme, not a poster.

A forester who had killed wolves and later wrote the mountain-as-ethics essay (1949). The US environmental canon still starts many wolf talks there.

A closed wolf-moose system studied since 1958. Inbreeding and later genetic rescue (2018-) made it a lab of isolation.

Pack coordination and canine social cognition sit high. Gorillas and elephants still outrank them. Scores are relative, not IQ certificates.

Yes in parts of Germany, France, Spain and Italy after legal protection. Livestock compensation is the daily politics, not a Yellowstone clone.

Folklore is a cultural-impact input. It is not a diet study.

Pandas are bamboo specialists in a small mountain belt. They do not engineer continents like elephants or move ocean nutrients like whales. The score is relative, not an insult.

VU is better than EN. Fragmented habitat, bamboo die-off cycles and a still-small wild number keep the species in a watch band, not a recovered one like koi or many owls.

The 1961 logo drew on Chi-Chi at London Zoo -- a high-contrast animal that printed well. The brand and the wild census later had to share one face.

Ling-Ling and Hsing-Hsing at the National Zoo made panda diplomacy a Cold War soft-power tool that China still uses as loans, not gifts.

The Sichuan earthquake killed staff and animals and wrecked the breeding centre. Rebuilding became a national reconstruction exhibit.

An American who took Su Lin out of China in 1936 -- a living-export story that predates modern loan contracts.

Captive numbers rose. Wild recovery needs corridors (the national park idea) more than more cubs on camera.

No. Ailurus is a different family. This atlas type is the giant panda only.

IUCN VU and the 2008 ESA listing rest on ice-season length. A few stable stocks do not cancel a circumpolar ice forecast. High resilience in this atlas means secure (koi, many owls), not famous.

It treated greenhouse gases as a listed-species threat. Courts later limited how far that could reach power plants; the biological finding stayed.

Western Hudson Bay is an early-ice-loss stock and a tourist town. It is a visible subpopulation, not the whole Arctic.

A hand-reared Berlin cub (2006-2011) whose fame and death made zoo ethics a tabloid. He is culture, not a sea-ice time series.

Seals (especially ringed) are the fat that pays. Bird eggs, carrion and land food appear more in long ice-free summers -- a budget problem, not a new niche that replaces ice.

The 1922 film staged Inuit life for a southern camera. It is a portrayal, not an ethnography of nanuq knowledge.

No. They are cultural impact. The atlas keeps them off the scores for ice.

The IUCN Polar Bear Specialist Group and USGS ice-bear models are the technical chorus behind the VU card.

The taxonomy wiki is Western gorilla. Mountain gorillas are G. beringei, fewer, more filmed, and less CR. The atlas follows the listed type, not the movie.

Karisoke watched mountain gorillas in Rwanda. The methods and the murder belong to that species; western gorillas have Mbeli Bai and different threats (Ebola, bushmeat).

Francine Patterson project treated signs as words. Linguists remain split. The atlas files Koko as culture and a research programme, not as proof that wild western gorillas recite English.

CR western gorillas plus Ebola, logging and hunt. Mountain gorilla rebound is real and is a different species card.

A forest clearing in Nouabale-Ndoki where western gorillas come for minerals -- a platform study that rarely makes a biopic.

The 1988 film helped mountain gorilla tourism and the Fossey myth. Western lowland numbers kept falling on a different map.

Western lowland gorillas are the usual zoo gorilla. Captive groups do not replace Gabon and Congo forests.

A mountain gorilla poached in 1977. Fossey used the death to fund anti-poaching -- a mountain, not western, story that still titles books.

Some Northern Hemisphere stocks look better. Antarctic blues remain far below pre-whaling. EN is still the honest card.

The IWC protected blue whales after the factory-ship years had already taken the Antarctic majority. Protection was a lock on an empty room in the south.

It is a commercial-whaling pause for many species. Blues were already protected; the moratorium is the political weather that kept factory ships from a sequel.

A blue whale eats tonnes of krill and returns nutrients in faecal plumes; a fall feeds the benthos. In this atlas that pump outranks most terrestrial carnivores except elephants and wolves.

Payne whale-song fame is mostly humpback. Blue-whale acoustics (low-frequency pulses) are a later Navy-and-NOAA file.

A southern subspecies/form -- smaller, still EN, often confused in catch histories.

In some coastal stocks (Sri Lanka, California) yes -- a recovery problem that 1966 did not imagine.

Save the Whales was huge; lions and tigers still win flags and millennia of art. Scores are relative across 24, not a concert-poster contest.
