Frequency signatures: White Grub to Whooper Swan

Each card gives a species’ behavioural archetype, its frequency — how often it commits effort and how long each commitment lasts — and a waveform tracing that rhythm.

Frequency signatures

Each waveform traces one species’ working rhythm — where it spends effort, and where it waits. 2,327 species, A–Z; showing 2,233–2,256.

White Grub

LOW

Hindgut-Fermented Root Feeding

Curled underground • Rasping roots • Fermenting it slowly

Because everything runs at the pace of microbial digestion in the dark, it operates as a low-frequency system.

White Peacock Butterfly

MID

Pale-Wing Open-Ground Basking

Perching low on bare ground • Wings held flat and open • Holding a small patch against rivals

Since those run continuously through the sunlit hours, it operates as a mid-frequency system.

White Rhinoceros

MID

Square-Lip Bulk Intake

Continuous • Cropping • Bulk

Because the whole architecture converts constant moderate intake into constant size rather than storing or bursting, it is a mid-frequency system.

White Seabream

MID

Cutters Front, Grinders Behind

Broad chisel-like incisors at the front of the jaw for cropping and scraping • Rows of rounded molars further back for crushing • The two sets used in sequence so a single mouth both detaches and processes hard prey

Because feeding is continuous, it operates as a mid-frequency system.

White Stork

MID

A Route Made of Thermals

Nesting • Fixed • Returned to

That makes it a bimodal system: a fixed, returned-to breeding site and a long cheap journey dictated by the air.

White Underwing Moth

LOW

Colour Shown Then Instantly Hidden

At rest on birch, forewings closed over the body in a pattern of white, grey and black that matches the bark exactly

These are not two settings of one defence but opposite strategies, one built on never being seen and the other on being seen very clearly and then not, so it operates as a bimodal system.

White-backed Vulture

LOW

Neighbour-Watching Descent Cue

Soaring • Watching • Converging

Because a very cheap search is punctuated by rare concentrated feeding, it is a low-frequency system.

White-bellied Sea Eagle

LOW

Height Spent as Attack Energy

Perched • Soaring • Reading water

Long cheap watching paying for a short converted descent makes this a bimodal system, low-frequency aloft and high-frequency coming down.

White-browed Fantail

HIGH

A Tail as Rudder

A broad tail spread into a fan and used to generate abrupt changes of direction in flight • Insects flushed from foliage taken in the air, with the fantail matching every turn they make • The tail providing the control surface for manoeuvres a bird with a narrow tail could not execute, so evasive prey is followed rather than pursued in a straight line

Because the turns come in rapid sequence, it operates as a high-frequency system.

White-faced Capuchin

HIGH

Testing the Bond by Making It Costly

Handling • Testing • Transmitted

That makes it a high-frequency system: continuously manipulative, continuously social.

White-faced Saki

MID

Eating Fruit Before Anyone Else Can

Bounding through canopy • Opening hard fruit • Destroying seeds

Continuous daily feeding and travel makes this a mid-frequency system.

White-faced Whistling-duck

MID

A Flock Held Together by Whistling

Whistling • Dense • Nocturnal

That makes it a mid-frequency system: continuously vocal and continuously grouped.

White-headed Fruit Dove

LOW

One Dove Per Island Group

A genus of fruit doves distributed across the Pacific with each island group holding its own species • Populations separated by sea crossings too long for a small canopy dove to make routinely • Each isolated group diverging in plumage and voice until it no longer recognises or interbreeds with its neighbours

Because divergence runs across evolutionary time, it operates as a low-frequency system.

White-headed Vulture

LOW

Acid Strong Enough to Erase Disease

Soaring alone • Arriving early • Digesting what would kill anything else

Slow, wide-ranging and long-lived, this is a low-frequency system.

White-nosed Coati

MID

Hands That Test Everything

Handling • Testing • Persistent

That makes it a mid-frequency system: continuously investigative rather than reactive.

White-rumped Vulture

LOW

A Gut That Sterilises

Finding a carcass from the air and gathering in numbers • Stripping it within hours • Passing the material through a gut acidic enough to destroy anthrax spores, botulinum toxin and cholera

Since the cycle runs across years, it operates as a low-frequency system.

White-spotted Pufferfish

MID

Sand-Mandala Courtship Builder

Rhythmic • Site-bound • Forager

Together this makes a bimodal system: a stable, site-bound mid-frequency routine that supports a high-frequency window of elaborate sand patterning and display.

White-tailed Deer

MID

A White Flag While Running

Feeding with the tail held down and the white underside hidden • Raising and flaring the tail on detecting a threat • Running with it up, making an unmissable moving signal

Since alarm events recur, it operates as a mid-frequency system.

White-tailed Tropicbird

MID

Legs Too Far Back to Walk

Soaring • Plunging • Returning to a crevice

Continuous daily foraging across open ocean makes this a mid-frequency system.

White-throated Dipper

MID

Cold-current Foraging Walker

Rhythmic • Site-faithful • Forager

Because its whole system is built around these coordinated, repeatable foraging cycles in a specific, challenging flow, the dipper is best understood as a mid-frequency system: rhythmic, place-bound and activity-led rather than purely slow or explosively fast.

White-throated Kingfisher

MID

Aiming Where It Is Not

Prey below the surface appearing displaced because light bends as it leaves the water • The bird judging the real position rather than the apparent one before committing to a dive • That correction applied from a perch at whatever angle the bird happens to be sitting at, so the offset differs on every attempt

Because dives recur, it operates as a mid-frequency system.
