Frequency signatures: Montezuma Oropendola to Mudpuppy
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 1,393–1,416.
Montezuma Oropendola
Canopy Colony Resonator
Colony • Rhythmic • Hanging
That makes this a bimodal system: a mid-frequency colony engine that continuously operates the hanging structure, and a high-frequency edge-display burst that rides on top of it.
Moon Jellyfish
The Drift-Assisted Pulse
Carried • Pulsing • Contact-fed
That makes it a low-frequency system: it adds a small amount of work to a flow that is already doing most of the job.
Moon Rat
A Hedgehog That Smells Instead
Nocturnal • Unspined • Pungent
That makes it a low-frequency system: slow, unhurried and defended by smell.
Moorish Idol
Flat Body, Tubular Snout
Sliding • Reaching • Picking
That makes it a mid-frequency system: constant low-yield grazing through an unusually narrow feeding apparatus.
Moose
Legs Long Enough for the Snow
Browsing • Solitary • Deliberate
That makes it a bimodal system: deliberate terrestrial browsing and a distinct aquatic feeding phase.
Moray Eel
A Second Set of Jaws in the Throat
Wedged • Anchored • Breathing
That makes it a bimodal system: prolonged anchored stillness and a rare two-stage mechanical strike.
Mosquito
The Micro-Opportunity Oscillator
Rapid • Reactive • Repetitive
That makes the mosquito a high-frequency system: reactive, agile and built around repeated micro-opportunities.
Moss Mimic Stick Insect
Ragged Lobes That Read as Moss
Motionless • Masquerading • Epiphyte-matched
That makes it a bimodal system: long motionless daytime masquerade and slow nocturnal feeding.
Mossy Frog
Tubercled Moss Imitation
Still • Textured • Wet-rock
Because the whole system substitutes structural resemblance for speed, defence or activity, it is a low-frequency system.
Mossy Leaf-tailed Gecko
Skin Fringes That Erase the Shadow
Flattened • Shadowless • Bark-matched
That makes it a bimodal system: flattened daytime concealment and night hunting.
Mouflon
Rank Read Off the Curl
Grazing • Assessing • Deferring
That makes it a mid-frequency system: steady social grazing in which an honest signal keeps the price of rank low.
Mound-building Termite
A Colony That Farms Digestion
Gathering plant material • Feeding it to a fungus comb inside the mound • Eating the fungus and the partly digested substrate
Since foraging and comb turnover run continuously, it operates as a mid-frequency system.
Mountain Beaver
A Kidney That Cannot Save Water
Burrowing in wet soil • Cutting vegetation • Drinking constantly
This is a low-frequency system.
Mountain Goat
Hard-Rimmed Hoof, Soft Pad
Deliberate • Gripping • Cliff-bound
Careful low-expenditure movement on poor alpine forage makes this a single low-frequency system.
Mountain Gorilla
A Family Held Together by One Silverback
Feeding • Resting • Cohesive
That makes it a bimodal system: slow feeding and resting, and short, rare displays.
Mountain Hare
Coat Turning White Ahead of the Snow
Resting • Camouflaged • Still
That makes it a bimodal system: still daytime rest in the form and nocturnal feeding.
Mountain Nyala
Heath-Belt Altitudinal Shuttle
Shifting • Browsing • Altitudinal
Because the shifting runs as a steady repeated cycle, it is a mid-frequency system.
Mountain Reedbuck
Grazing the Slope With the Escape Uphill
Grazing • Small-group • Hillside
The system is bimodal: steady hillside grazing and brief, explosive flight.
Mountain Tapir
Woolly Coat at Páramo Altitude
Woolly • High • Browsing
Because browsing and moving run as a steady daily cycle, it is a mid-frequency system.
Mountain Zebra
Hard-Hoof Escarpment Circuit
Climbing • Grazing • Daily
Because the animal converts steady walking and continuous grazing into a living on marginal ground, it is a mid-frequency system.
Mourning Cloak
A Year on the Wing
Emerging in midsummer and feeding on tree sap and rotting fruit rather than nectar • Entering dormancy in a cavity before autumn • Reappearing in early spring, mating and dying after nearly a year on the wing
Since the cycle is annual, it operates as a low-frequency system.
Mourning Dove
Crop-Milk Brood Turnover
Gathering seed • Making milk • Starting again
Because that rhythm is continuous across a long season, it operates as a mid-frequency system.
Mud Dauber
Building and Stocking a Cell
Collecting mud in pellets and shaping it into tubular cells on a sheltered surface • Hunting spiders, paralysing them with a sting that preserves rather than kills • Packing several into each cell with one egg and sealing it before starting the next
Because the cycle runs seasonally, it operates as a low-frequency system.
Mudpuppy
A Door That Cannot Be Reopened
Walking the bottom • Breathing through feathered gills • Active all winter
Slow and unchanging throughout, this is a low-frequency system.
