Frequency signatures: Common Quail to Common Wanderer
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 529–552.
Common Quail
The Only Gamebird That Leaves
Breeding in one crop and moving on as it is cut • Crossing the Sahara twice a year • Following green cereal northward across a season
Since breeding attempts shift within a season, it operates as a mid-frequency system.
Common Rat Snake
Incremental Shedding Grower
Rhythmic • Renewal • Cycles
This produces a mid-frequency system built on recurring, whole-body renewal pulses rather than constant micro-adjustment or rare one-time transformations: a steady rhythm of operate–accumulate–shed–resume that lets the animal keep extending beyond previous physical limits.
Common Raven
The Context-Reading Cacher
Watching • Learning • Caching
Because the behaviour is selected to match the context rather than fixed to one tempo, the raven is best described as an adaptive system: a steady watching-and-storing baseline that can switch into fast opportunistic action.
Common Roach
A Body Deepened by Pike
Shoaling in open water and among weed • Growing deeper-bodied where predators are abundant • Becoming too tall for a pike's gape to close on
Since feeding and shoaling are continuous, it operates as a mid-frequency system.
Common Rose
The Original Behind the Imitations
Larvae feeding on Aristolochia vines and sequestering aristolochic acids that make the adult genuinely unpalatable • A slow deliberate flight and a conspicuous red body advertising that fact clearly • Several unrelated butterflies converging on the same appearance, so the model bears the cost of the education while the mimics do not
Because the cycle runs generationally, it operates as a low-frequency system.
Common Rotifer
Ciliated Wheel Feeder
Rhythmic • Filtering • Flow
The result is a multimodal rhythm: mid-frequency ongoing wheel-feeding, punctuated by high-frequency renewal bursts and underpinned by low-frequency dormancy that lets the cycle repeat across changing freshwater conditions.
Common Rough Woodlouse
Slowing Down in Damp Air
Walking fast and turning often while the air is dry • Slowing and turning less as soon as the air becomes humid • Accumulating in damp places without ever steering towards them
Because the response is continuous, it operates as a mid-frequency system.
Common Sand Dollar
Submerged Sand Filter
Flat • Hidden • Sifting
This architecture of staying put, staying hidden, and letting the environment bring resources defines a low-frequency system built on quiet, continuous intake.
Common Sawshark
Seafloor Rostrum Sweep
Rhythmic • Sweeping • Bottom-hunting
Its life is built from many such passes—resting near the bottom, then resuming this patterned search when food and safety coincide—so its operating rhythm is a coordinated, ongoing mid-frequency system driven by repeated rostrum sweeps rather than rare huge bursts or deep, static conservation.
Common Scorpionfly
A Long Beak Robbing Spider Webs
Scavenging • Low-cover • Steady
That makes it a bimodal system: steady scavenging in low cover and brief raids on webs.
Common Seahorse
Square-Tailed Holdfast Strike
Gripping a stem • Eyes moving separately • Snapping the head upward
Because that rhythm never pauses, it operates as a mid-frequency system.
Common Snapping Turtle
Reduced Plastron, Long-Neck Strike
Silted • Motionless • Decades
Long cheap concealment paying for one committed reach makes this a bimodal system, low-frequency in the mud and high-frequency at the strike.
Common Sole
Feeling With the Blind Side
Lying buried in soft sediment through the day • Emerging after dark and pressing the blind side of the head to the bottom • Locating buried worms with dense sensory papillae and taking them without seeing anything
Since feeding actions repeat through the night, it operates as a mid-frequency system.
Common Spider Tortoise
Rain-Timed Patterned Dome
Sheltered • Dormant • Patterned
Rain is the switch: months of near-zero spending under a camouflaging shell give way to a short, rhythmic season of feeding and laying, which makes the system bimodal, low-frequency in the dry months and mid-frequency in the wet.
Common Stingray
A Spine That Tears
A serrated spine mounted on the upper surface of the tail, pointing backwards • Backward-facing barbs along both edges so the spine enters cleanly and resists being pulled out • A venom-bearing sheath rupturing on entry and delivering its contents into the wound
Because encounters are rare, it operates as a low-frequency system.
Common Sun Skink
Live Young, Not Eggs
Retaining developing embryos inside the body for weeks • Supplying them through a placental connection rather than a yolk alone • Giving birth to fully formed young that can run immediately
Since the cycle is annual, it operates as a low-frequency system.
Common Swift
Roosting on the Air After Dusk
Hawking • Weather-tracking • Airborne
That makes it a bimodal system: daytime aerial feeding and nocturnal high-altitude resting.
Common Tailorbird
Leaf-Sewn Canopy Nester
Rhythmic • Site-bound • Craft
This creates a mid-frequency system: not a slow reserve hoarder or a pure burst hunter, but a steady, site-bound rhythm of sewing, foraging, and returning to the same stitched canopy.
Common Tenrec
Seasonal Multi-gear Forager
Sheltered • Torpid • Hidden
Because its survival depends on moving between concealed torpor, routine flexible foraging, and brief defensive bursts rather than living in a single operating tempo, the common tenrec is best understood as a multimodal system spanning low, mid and high frequencies.
Common Treeshrew
Snout-First Forager of the Forest Floor
Diurnal • Probing • Restless
Because the system is a steady daytime routine of rapid, probing searches rather than either long rest or explosive action, it is a mid-frequency system.
Common Vampire Bat
Blood Debts Repaid in the Roost
Sharing • Grooming • Reciprocating
That makes it a bimodal system: patient nocturnal feeding and a social exchange phase in the roost.
Common Wall Gecko
Microhair Adhesion Lattice
Rhythmic • Anchored • Incremental
That produces a mid-frequency system: continuous, stepwise movement built from tightly controlled, repeating contact cycles rather than slow reserve use or explosive sprinting.
Common Wall Lizard
Digestion Rebuilt in Thirty Years
Basking on stone until warm enough to move • Foraging across vertical rock and wall faces • Shifting diet to whatever the site actually supplies
Since foraging bouts recur, it operates as a mid-frequency system.
Common Wanderer
Only the Female Mimics
A male in plain bluish white with black veining, flying fast and erratically, unprotected and behaving accordingly
This is sex-limited Batesian mimicry, and the two sexes therefore run genuinely different defensive systems in the same species, so it operates as a bimodal system.
