Animal Tracking Honor

Nature Study

Requirements

1. Know how to identify at least 10 types of animal tracks, including 2 of birds. Make at least 5 raised plaster casts of the tracks of different animals.

   Answer: Identify 10 tracks: dog, cat, horse, cow, capybara, jaguar, fox, rabbit, chicken (bird), pigeon (bird). For 5 casts: prepare plaster (water+powder), apply over a track in mud/sand, wait 30 min, remove it, and identify. — Tracks vary by number of toes, presence of claws, and size. Felines retract their claws (no mark), canids do not. Horse/cow hooves are distinct. Bird tracks show 3-4 toes with claws. Plaster (calcium sulfate) hardens in 20-30 min, creating a permanent record for study.

2. Cite at least 3 things that tracks tell us.

   Answer: Tracks reveal: 1) Which animal passed by (species, size, approximate age); 2) Direction and speed (walking or running); 3) How much time has passed (fresh vs. old). — Brazilian Indigenous trackers distinguish dozens of details in a footprint. Depth indicates weight; the spacing between steps indicates speed. A track with little debris indicates it was recently made. In zoology, this knowledge helps estimate populations and behaviors without capturing animals.

3. Follow the trail left by an animal. If possible, identify the animal and tell whether it was running or walking.

   Answer: When running, an animal lifts its body more and extends its strides further. Fleeing predators leave tracks with churned-up earth. Blood or hairs can indicate a recent hunt. Trained Indigenous people track for days, following even small details — a skill that still impresses modern professional biologists today.

4. Set up and maintain a tracking area for at least 3 days, observing the following:
   • Select an open spot in a quiet place near your campsite, home, or rural area.
   • Smooth the ground, making it suitable for recording the tracks of animals that pass by.
   • Put out food for wild animals.
   • Check daily whether the spot has been visited and replenish the food if necessary.

   Answer: Choose an open, quiet spot near home/camp. Smooth the soil (mud or sand) to record marks. Place attractive food (fruits, seeds). — Wild animals are shy — food attracts them without needing to see the animal. A quiet location avoids scaring them away. Smoothed soil is a blank canvas for tracks. Similar studies are done by biologists with camera traps. 3 days is the minimum time to map the routine of the area's regular visitors.

5. Cite at least 2 animals for each group.
   • With flat feet.
   • That walk on the tips of their feet.
   • That walk on the tips of their toes.
   • With nails or claws.

   Answer: 1) With flat feet (plantigrade, resting the entire sole): bear and opossum (humans and the raccoon also fit here). 2) That walk on their toes (digitigrade, resting on the toes): cat and dog (also the fox and the wolf). 3) That walk on the tips of their toes (unguligrade, resting only on the hoof, at the toe tips): horse and cow. 4) With nails or claws: cat and dog (with claws), as well as bear, armadillo, and capybara, whose tracks show the marks of the claws. — Plantigrades (flat feet like the bear) leave a full footprint. Digitigrades (dogs, cats) walk only on their toes. Unguligrades (horses, cows) walk only on the hoof. Claws help with climbing and defense. Evolutionary adaptations reflect diet and habitat — predators have retractable or sharp claws for hunting.

6. Identify at least 4 signs of the presence of mammals.

   Answer: Four signs: 1) Tracks in soft soil; 2) Droppings (shape and size identify the species); 3) Hairs on bushes or fences; 4) Claw marks on trunks or feeding signs (gnawed bark, partially eaten fruit). — Droppings (scat) are a valuable bioindicator — the jaguar leaves droppings with the hairs and bones of its prey. Hairs on electric fences or wire are common. Claw marks on trunks by felines are territorial. Biologists use camera traps combined with these indirect signs for confirmation.

7. Know how to distinguish between the tracks of canids, felids, and other carnivores common in your region.

   Answer: Canids (dog, wolf, fox): track with 4 toes, claws usually visible (non-retractable), a more triangular central pad, oval/elongated shape, and the set tends to be more symmetrical. Felids (cat, jaguar, ocelot, wildcat): track with 4 toes without claw marks (they are retractable), a wide central pad with three lobes on the rear edge, a more rounded shape. Other common carnivores: mustelids (ferret, otter) leave 5 toes with claws and webbing; procyonids (crab-eating raccoon/raccoon) leave 5 long toes resembling little hands. Practical summary: visible claws + oval shape = dog/fox; no claws + rounded = feline; 5 toes = mustelid or crab-eating raccoon. — Felines' retractable claws are an adaptation for silent hunting — they do not wear down and stay sharp. Canids run and use their claws for traction, always visible. Mustelids have 5 toes while felines/canids have 4. This helps biologists estimate populations of endangered species such as the jaguar.

8. List at least 2 groups of animals (mammals, birds, insects, etc.) that leave odors along the trail they make so that others of the same species can follow.

   Answer: Two groups: 1) Ants — they leave pheromone trails that others follow to food sources. 2) Mammals such as dogs and wolves — they mark territory with urine and glandular secretions. — Pheromones are chemical substances for communication within the same species. Ants follow precise trails toward food. Dogs urinate on posts to mark territory — mutual social communication. The emperor moth can detect a female's pheromones from 10 km away in the air, an extreme example.

9. Cite at least 2 birds that, by their tracks, are:
   • Jump
   • Walk

   Answer: 1) Birds that hop: sparrow and rufous-collared sparrow, whose tracks appear in parallel pairs, with both feet marking side by side at each hop. 2) Birds that walk: dove and chicken, whose tracks are alternating, marking one foot after the other as in a walk. — Small birds hop to spend less energy in quick movements. Chickens and doves, with sturdier feet, walk regularly. In ornithological tracking, parallel vs. alternating steps are the first identification indicator. The pattern combines with the track's size to identify the exact species.

10. Besides tracks, mention 2 other signs of the presence of birds.

    Answer: Two other signs of the presence of birds, besides tracks: 1) Songs and vocalizations — each species has its own sound that reveals its presence even without being seen. 2) Feathers lost on the ground, in bushes, or near nests. Other possible signs: nests, eggs or eggshells, whitish droppings on branches/rocks, and feeding remains (shells, gnawed seeds). — Songs identify more than 90% of Brazilian birds without needing to see them. Feathers have specific patterns by species. Nests range from simple (on the ground) to complex (a woven basket). Modern apps like Merlin (Cornell University) recognize songs automatically — useful for beginners in ornithology.

11. Cite two birds identified by their flight pattern and describe the pattern.

    Answer: Two birds: 1) Hummingbird — it flies stationary (hovers in the air), beating its wings up to 80 times per second. 2) Vulture — it glides in high circles taking advantage of thermal currents, without beating its wings. — The hummingbird is unique among birds in being able to fly backward. Vultures locate carcasses using gliding flight. Woodpeckers undulate in flight (rise-beat-wings, glide, rise-beat-wings). Flight is diagnostic in birdwatching — experienced observers identify species hundreds of meters away by the flight pattern alone.

12. In your region, observe tracks, trails, or footprints of 1 or more of the following animals:
    • Toad or frog
    • Snake
    • Turtle, terrapin, or tortoise
    • Mollusk
    • Earthworm
    • Rodents

    Answer: Go out on a real search and observe tracks: toad/frog (hops with 4 visible toes); snake (a continuous winding line); tortoise (round tracks with grooves); mollusk (a shiny trail of mucus). — Each animal leaves a specific mark. Snakes leave a continuous line without footprints. Slugs/snails leave a shiny mucus trail (protection against dehydration). Rodents such as rats have small tracks with 4-5 toes. Documentation with photos serves as proof of field work done and aids in studies.
