  1. Field guideWhy bears wander into townsA bear in a town is usually following its stomach, not hunting people. When wild foods such as acorns or berries fail, and when rubbish, fruit, pet food, or feeders are reachable, bears learn that settlements are worth the risk—so most conflict traces back to food that people can secure.
  2. Field guideCute but dangerous: animals not to approachWanting to touch a wild animal is not foolishness; it is a wired response to a set of physical features, and it fires whether or not the animal is safe. The animals below are all things people reach for. Their defences run from a venomous ankle spur to a virus with an 80 per cent untreated fatality rate, and almost none of them are visible until they are used.
  3. Field guideHibernation, torpor, and dormancyDormancy is a broad reduction in activity or development. Torpor is a regulated fall in metabolism and often body temperature; hibernation usually describes a seasonal strategy built from prolonged torpor bouts and periodic arousals, though usage differs by source.
  4. Field guideFieldcraft: getting closer without disturbingFieldcraft is patience and controlled movement, used only where quiet observation is safe. The goal is to avoid disrupting the animal, not to approach unseen.
  5. Field guideHow close is too close to wildlife?Viewing distances vary by jurisdiction, species, activity, season, and site. Some are enforceable rules; others are official guidance. Check the place-specific requirement and back away whenever wildlife responds to you.
  6. Field guideHow beavers build damsA beaver dam is a maintained, leaky barrier rather than a concrete wall. It reduces current and raises local water depth, helping create aquatic access and refuge; as flow finds gaps and materials shift, beavers add branches, sediment, and vegetation where construction cues are strongest.
  7. Field guideHow carnivorous plants trap preySticky flypaper, slippery pitchers, snap traps, suction bladders, and inward-pointing passage traps evolved independently in nutrient-poor habitats. Glands and trap communities break prey into soluble compounds that plant tissues absorb, especially nitrogen and phosphorus; sunlight still supplies the energy and carbon for growth.
  8. Field guideHow caterpillars defend themselvesA caterpillar's defense is often layered. Avoiding detection comes first; after discovery it may posture, flee, drop, expose spines, click, regurgitate, or advertise chemicals acquired from its host plant.
  9. Field guideHow seeds travelPlants disperse seeds through several physical and biological routes. Wings, plumes, buoyant tissues, hooks, fleshy fruits, and spring-loaded pods offer clues, but a structure shows potential rather than proving how far a particular seed traveled.
  10. Field guideMetapopulations and wildlife corridorsIn a metapopulation, organisms occupy a set of habitat patches connected enough for dispersal but separate enough that local dynamics differ. Movement can recolonize empty patches and rescue declining ones. Corridors and crossings may improve connectivity, but their value is a measured outcome, not a property of any green strip on a map.
  11. Field guidePhotographing fungi for identificationFungal identification depends on structures that a top-down mushroom portrait conceals. Record the whole fruiting body, cap surface, underside, stem and base, substrate, nearby age stages, and field context without tasting or harvesting it.
  12. Field guideReading scat & signMost of the time the animal is gone and the ground is too hard for prints. Sign is what remains, and it is often more specific than a track.
  13. Field guideUrban wildlife coexistence basicsCoexistence starts with changing the human-controlled parts of an encounter: food, trash, access to buildings, pets, distance, and timely local reporting.
  14. Field guideWhy animals playLook for actions that are modified from their ordinary function, repeated but not rigid, initiated in relatively relaxed conditions, and balanced by signals or self-handicapping; compare sequences before labeling them play.
