Frequency signatures: Lesser Bird-of-paradise to Long-eared Owl
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 1,249–1,272.
Lesser Bird-of-paradise
Plumed Canopy Choreography
Quiet • Hidden • Preparing
Because the bird’s biology is built around long periods of hidden preparation punctuated by short, high-intensity, highly organized performances, it operates as a bimodal system with a low-frequency maintenance mode and a high-frequency display mode.
Lesser Grison
Low Body, Any Ground
Following • Low • Everywhere
That makes it a mid-frequency system: persistently active across every kind of ground rather than fast on any one.
Lesser Hedgehog Tenrec
Body Temperature Left to Drift
Searching leaf litter • Curling up • Shutting down for months
Slow, conservative and reserve-based, this is a low-frequency system.
Lesser Kudu
Ear-Led Thicket Freeze
Listening • Freezing • Browsing
Because the system runs on continuous listening and short cautious feeding movements, it is a mid-frequency system.
Lesser Mouse-deer
Pencil-Legged Slipping Through the Understorey
Browsing • Secretive • Path-following
That makes it a bimodal system: secretive foraging along forest paths and explosive escape into cover.
Lesser Sandeel
Diving Into the Seabed Itself
Shoaling in open water over sandbanks by day • Driving headfirst into coarse sand with a pointed snout and elongated body • Spending nights and whole winter months buried in the sediment
Since emergence recurs daily, it operates as a mid-frequency system.
Lesser Whistling Duck
Both Parents Doing Everything
Male and female indistinguishable in plumage, with no display difference between them • Both birds incubating in turn rather than the female alone • Both escorting and defending the ducklings for months after hatching
Because the alternation is continuous, it operates as a mid-frequency system.
Lichen Katydid
Pale Branching Outline Matched to Lichen
Pressed • Lichen-matched • Motionless
That makes it a bimodal system: daytime lichen masquerade and night activity.
Lilac-breasted Roller
Exposed Perch, Rolling Dive
Perched • Exposed • Scanning
That makes it a bimodal system: a long still watch and a brief, steep, highly visible commitment.
Lined Day Gecko
Sunlit Leaf-Matched Forager
Basking • Darting • Leaf-matched
Repeated cycles of warming, short dashes and feeding through every sunny day give a steady mid-frequency rhythm.
Lion-tailed Macaque
Cheek-Pouch Canopy Harvesting
Pouched • Canopy-bound • Daily
Because feeding runs as a steady daily cycle, it is a mid-frequency system.
Lionfish
Spined Fan Corral
Drifting • Undeterred • Spined
That makes it a bimodal system: an unhurried protected cruise and a brief engulfing event.
Little Auk
A Throat Pouch Full of Copepods
Diving • Pouch-loading • Rapid
That makes it a bimodal system: rapid provisioning trips and longer restorative trips.
Little Barrier Giant Weta
Insect Filling a Mouse's Place
Heavy • Flightless • Browsing
Slow heavy browsing makes this a single low-frequency system.
Little Dragonfish
Armored Pectoral Crawler
Cautious • Terrain-led • Walker
That makes this a low-frequency system: dense, conservative, and organized around careful seafloor walking instead of rapid bursts or continuous cruising.
Little Egret
Dashing Shallow Pursuit
Dashing • Wing-flicking • Opportunist
That makes it a mid-frequency system: active, rhythmic and built on repeatedly manufacturing short-lived advantages rather than on patience.
Little Owl
An Owl That Hunts Afoot
Watching from a low perch in open farmland at dusk and by day • Dropping onto the ground and then running after prey on long legs • Taking beetles, earthworms and insects as well as small mammals
Since hunting drops recur constantly, it operates as a mid-frequency system.
Little Wood-Satyr
Eyespots at the Wing Edge
Resting with wings closed and small ringed eyespots along the outer margin • Having birds strike at those spots rather than at the body • Flying off with a notched wing and an intact thorax
Since encounters recur, it operates as a mid-frequency system.
Llama
Padded-Foot Load Carry
Carrying • Sure-footed • Sparse-fed
That makes the llama a low-frequency system: economical, sure-footed and built for sustained effort on very little input.
Loggerhead Sea Turtle
Current-Riding Magnetic Map
Decadal • Drifting • Durable
Because the whole system is built on cheap movement, deep patience and a horizon measured in decades, it is a low-frequency system.
Loggerhead Shrike
A Thorn Standing In for Talons
Perched • Scanning • Patient
That produces a bimodal system: long low-frequency spells of scanning from perches, punctuated by fast, violent strikes and the handling that follows.
Long-eared Hedgehog
Big Ears for Hot Nights
Burrowing • Resting • Heat-avoiding
That makes it a bimodal system: a sheltered daytime burrow and night-time foraging.
Long-eared Jerboa
Ears Tuned to Insects in the Dark
Burrowed • Sealed • Dormant
The biology of this species is poorly studied, but the pattern is clear: a bimodal system of long sheltered rest and short, fast, sound-guided hunting.
Long-eared Owl
Wings Quiet Enough to Hear Past
Quartering • Listening • Dropping
That makes it a low-frequency system: slow, cheap, patient flight built around detecting something very quiet.
