Animal Behavior Animal Behavior Vocabulary Ethology = study of animal behavior Behavior = action performed in response to stimulus Whale tail The things animals do…. Vocabulary Vocabulary- other stimuli Examples of stimuli? Sight Touch Smell Taste Sound Heat Light Chemicals Humidity Vibration Color Gravity Pressure ★Presence of another animal Others? Stimuli Stimuli Stimulus = something that elicits a response External Stimulus = something outside the animal e.g. sound, sight, smell, etc, presence of another animal Internal Stimulus = something inside the animal e.g. hunger, fatigue, feeling cold, hormones 1 Types of Behavior Vocabulary Anthropomorphism = attributing human emotions to animals ★We need to be careful about ascribing human emotions to animals 1. Foraging = feeding e.g. locate, obtain & consume food E.g. the animal is happy Types of Behavior Types of Behavior 2. Parental Care = ensuring survival of young e.g. carrying, nursing, cuddling, holding young 3. Courtship = attracting a mate Courtship e.g. courtship displays, bright feathers, songs, other vocalizations, head butting, fighting Types of Behavior 4. Reproductive = e.g. mating, giving birth 2 Types of Behavior Types of Behavior 5. Offensive/Defensive = aggression, submissive behavior, defense from aggressors e.g. hiding, fighting, escape, threatening 6. Territorial = protect a resource for exclusive use e.g. scenting / marking, birdsong, protection of mate / offspring, space, food or water source Types of Behavior Types of Behavior 7. Social = work to create alliances, help the group e.g. grooming, babysitting, defense of musk ox young, play, play fight Types of Behavior 8. Migratory = movement to a more suitable environment as seasons change e.g. dry vs. rainy seasons, winter vs. summer range for browsers & birds e.g. salmon upriver to spawn, artic tern – 1800 m from Arctic to Antarctic, 2x/year Types of Behavior- Communication 9. Communication = signaling between one animal & another Greeting e.g. sniff, hug, kiss “bite” Aggression e. g. charge, bite, hit, fight, etc. Non-aggression e.g. patting, head butting, stroking Grooming (bonding, alliances, keeping clean) Group hunt ( e.g. hyenas, lions) 3 Types of Behavior- Communication Types of Behavior- Communication Vocalizations e.g. bark, growl, snort, howl, hoot, chirp, whinny, alarm sound, other language Why Communicate? Defense (warn away) Alliance (get helper or mate) Elicit play Non-verbal signaling e.g. body, head, ear, & / or tail position showing teeth, smiling, looking away, looking directly at, gesturing, thumping, beating chest, raising hackles or hood, drumming, tail slap, snort, scenting, pheromones, sign language Types of Behavior 10. Curiosity = investigating new stimulus in environment e.g. approach, sniff, chew, bite, mount Types of Behavior Types of Behavior 11. Elimination = defecation, urination 12. Resting = apparent inaction e.g. lying down, sitting, basking, sleeping, loafing 4 Types of Behavior Types of Behavior Development 13. Play Purpose = training for life (defense, hunting, etc) 1. Natural Selection An animal that successfully completes a helpful behavior survives to pass on the behavior to offspring. Those whose genes fit the conditions survive. Types of Behavior Development Types of Behavior Development 2. Innate Behavior Appear in fully functional form when first performed E.g. Startle behavior – purpose = self-preservation E.g. web building, suckling, bird begging, nest building, some bird song Types of Learning 3. Learning U development of behaviors through experience U determines final shape of innate behaviors U 5 types of learning Imprinting 1. Imprinting (both innate & learned) occurs only during a critical time frame once learned, can’t be changed (see Conrad Lorenz with ducklings) 5 Types of Learning Types of Learning 2. Habituation 3 Classical Conditioning Animal learns to associate unrelated response with a stimulus E.g. Pavlov’s experiments Animal learns to ignore frequent, harmless stimulus E.g. scarecrow, habituation to observer bell ringing, food, Î salivation bell ringing, salivation (even if no food is given) + + Î Classical Conditioning E.g. 1. leash = going for a walk, excitement 2. sight of leash = excitement Types of Learning 4. Operant Conditioning Animal learns to behave in a certain way through repeated practice Trial & error learning – animal tests conditions for desired response e.g. Skinner box Animal learns that a behavior gets a certain response e.g. rat presses lever, gets food 6 Types of Learning 5. Reasoning Analyze problem & devise solution using past experiences Most Dogs? E.g. No, can’t unwind leash from tree Most Horses? No Can primates reason? Can primates reason? Primates? yes e.g. chimp, bananas, boxes Can primates reason? Can primates reason? e.g. Japanese macaques float grain in water 7 ★See Alex the Parrot Jack Hana Video African Gray Parrot 8
