American Snail-eater

Spanish name
Caracolera articulada
Scientific name
Dipsas articulata

What Do Pico & Tati Think?

Pico: “What helps this reptile fit into its habitat?”

Tati: “Let’s look at its shape, colors and surroundings while giving it plenty of space.”

Identification

Key Features of the American Snail-eater

  • Slender body and narrow neck

  • Relatively large head and eyes

  • Dark blotches on a lighter background

Habitat & range

Humid forest and foothill vegetation on the Caribbean slope and in southwestern Costa Rica.

Conservation & care

Observe from a distance with an adult or qualified guide. Do not touch, catch, corner, feed or move any snake. Keep children and pets away. Colors, head shape and pupil shape must never be used to decide a snake is safe.

Threats & pressures

Protect connected habitat and natural shelters. Avoid collection, unnecessary clearing and deliberate killing. Leave wildlife in place and support responsible observation.

Baltimore Oriole

Spanish name
Bolsero norteño
Scientific name
Icterus galbula

What Do Pico & Tati Think?

Pico: “Did that bird travel here?”

Tati: “Baltimore orioles connect Costa Rica with places farther north.”

Identification

Key Features of the Baltimore Oriole

  • Male orange body and black head

  • White wingbar

  • Slender pointed bill

Habitat & range

A migrant and nonbreeding visitor, generally September to early May. Occurs on both slopes, especially the northern Pacific and Central Valley, in wooded gardens, edges and plantations.

Conservation & care

Observe quietly from trails or established viewing areas. Give nests, roosts and feeding birds space. Do not handle, chase or lure birds with playback. Keep pets away from wildlife.

Threats & pressures

Migrants depend on suitable habitat across their full annual journey. Protect native vegetation, reduce collision hazards around glass and keep cats away from birds. These are practical prevention priorities, not a claim of a measured decline at a specific Costa Rican site.

Nature Field Guide

Bejuco Cucharilla

Spanish name
Bejuco cucharilla
Scientific name
Bignonia diversifolia

What Do Pico & Tati Think?

Meet the plant behind Abu’s basket. Bejuco cucharilla is a woody climbing vine, also called a liana. It grows with the support of other plants. Its leafy shoots and lilac tubular flowers offer clues to its identity.

Costa Rican craft references document cucharilla as a material for woven baskets. Woody vine material can become more flexible when moistened, allowing a skilled maker to shape and weave it. A basket begins with a plant and takes form through patient work.

In our story, Abu learned to weave from her mother. Now she invites Pico and Tati to learn too. Her family history is fictional, while the connection between this vine and Costa Rican basket making is documented.

Scientific name note: Kew accepts Bignonia diversifolia. Many Costa Rican botanical and craft sources use the synonym Cydista diversifolia.

Identification

Key Features of the Bejuco Cucharilla

  • A woody climbing stem rather than a self-supporting tree trunk.

  • Opposite compound leaves, typically with two leaflets and sometimes a simple tendril.

  • Smooth-edged leaflets with pointed tips and a rounded or somewhat heart-shaped base.

  • Lilac to pinkish tubular flowers; young branches have a distinctly angular, four-sided form.

Habitat & range

Documented in Costa Rica’s lowland forests, including deciduous and semideciduous forest in Guanacaste. Botanical collections include Nandayure and Barra Honda on the Nicoya Peninsula.

Conservation & care

Observe and photograph vines without cutting or pulling them. Leave wild plants and flowers in place. Learn about materials from a knowledgeable artisan and use paper or responsibly sourced craft materials for your own weaving.

What Do Pico & Tati Think?

Warm-colored bark is a useful starting point when identifying indio desnudo. Look at the trunk, leaves and fruits together, as its appearance changes with the seasons.

Indio Desnudo Copper Bark Tree in Costa RIca

What does Least Concern mean?

In the linked conservation assessment, this species does not qualify as threatened or near threatened with extinction. It still needs care: local populations and habitats can face problems even when the species has a lower extinction risk overall.

This label describes conservation status. It does not tell us whether a plant is safe for children or pets. Select the status button to read the assessment.

Identification

Key Features of the Indio Desnudo

  • Warm orange-toned bark is an important clue.

  • The tree may lose its leaves during the dry season.

  • Look for small fruits in clusters at the ends of branches when present.

Habitat & range

Dry forest and other wooded habitats. Use several clues together and ask a guide before naming an unfamiliar tree.

Seasonal Calendar

Flowering

Guanacaste dry forest

Apr, May

ACG dry-forest reference: flowers appear in late April and May. Leaf cover varies through the dry season.

Event source ↗

Conservation & care

Child Safety: Not verified. Observe with an adult. Do not taste leaves, seeds, fruit or other tree parts.

Pet Safety: Not verified. Keep pets from chewing or swallowing tree parts. Check with a veterinarian before treating this species as pet-safe.

Keep bark intact. Observe without peeling, scratching or removing bark.

Conservation assessment

Global species assessment: Least Concern (IUCN Red List). Status checked on 7 October 2026. This category is not a guarantee that every local population or habitat is secure, and it is separate from legal protection in Costa Rica.

Scarlet Macaw

Spanish name
Lapa roja
Scientific name
Ara macao

What Do Pico & Tati Think?

Pico: “Those wings have three colors to discover!”

Tati: “Let’s listen, look up and give the pair room to fly.”

What does Least Concern mean?

In the linked conservation assessment, this species does not qualify as threatened or near threatened with extinction. It still needs care: local populations and habitats can face problems even when the species has a lower extinction risk overall.

This label describes conservation status. It does not tell us whether a plant is safe for children or pets. Select the status button to read the assessment.

Identification

Key Features of the Scarlet Macaw

  • Red body with yellow and blue wing feathers.

  • Long pointed tail and large pale upper bill.

  • Loud calls; birds may fly in pairs.

Habitat & range

Important populations occur around Carara and the Osa Peninsula. Guanacaste includes restored populations around Punta Islita; this does not imply occurrence throughout the region.

Seasonal Calendar

Breeding

Costa Rica; broad national window

Jan, Feb, Mar, Apr, Oct, Nov, Dec

Broad reported window, not a dated Carara nesting forecast.

Event source ↗

Conservation & care

Stay on authorized trails or viewing routes. Give birds space, keep voices low and leave nests undisturbed. Observe without bait, feeding or recorded calls.

Threats & pressures

Forest loss removes feeding and nesting trees. Capture for the pet trade also affects populations; global status does not describe every local population.

Conservation assessment

World Parrot Trust reports IUCN Least Concern; local declines are still documented. Source checked 7 October 2026. This is a global species category, not a count of birds in the tagged towns.

White-necked Jacobin

Spanish name
Jacobino nuquiblanco
Scientific name
Florisuga mellivora

What Do Pico & Tati Think?

Pico: “Its tail opened like a little white fan!”

Tati: “The white tail and blue hood are useful clues in a male.”

Identification

Key Features of the White-necked Jacobin

  • Male has blue hood

Conservation & care

Observe quietly from trails or established viewing areas. Give nests, roosts and feeding birds space. Do not handle, chase or lure birds with playback. Keep pets away from wildlife.

Threats & pressures

Protect native vegetation, reduce collision hazards around glass and keep cats away from birds. These are practical prevention priorities, not a claim of a measured decline at a specific Costa Rican site.
