Birds Cloud Forest

What Do Pico & Tati Think?

Pico: “A big bird is moving through the branches!”

Tati: “Look for its face and legs as well as its feathers.”

Least Concern

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 Black Guan

  • Black body without a curassow’s curled crest.

  • Blue bare skin around a red eye.

  • Reddish legs.

Montane forest, generally from about 1000 m to the upper forest limit. South Pacific refers to high Talamanca slopes, not coastal lowlands.

Seasonal Calendar

Resident presence

Costa Rica; suitable highland forest

Year-round

Resident nationally; presence and detectability vary among local sites.

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

Dependence on forest makes clearing and fragmentation relevant pressures despite the global Least Concern category.

Conservation assessment

BirdLife gives Least Concern, last assessment 2021. Source checked 7 October 2026. This is a global species category, not a count of birds in the tagged towns.

Nature Field Guide

Tiny Anole

Spanish name
Anolis microtus
Scientific name
Anolis microtus
Reptiles Cloud Forest · Tropical Rainforest

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 Tiny Anole

  • Large rather than tiny anole

  • Broad head and relatively short legs

  • Green-and-brown camouflage on a long-tailed body

Habitat & range

Premontane and lower montane forest in the Costa Rican highlands, particularly the Talamanca mountain system on both slopes.

Conservation & care

Observe with an adult from permitted paths. Do not touch, chase, catch or feed reptiles. Leave bark, logs, stones and leaf litter in place. Keep pets away and allow an open escape route.

Threats & pressures

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

Nature Field Guide

Violet Sabrewing

Spanish name
Ala de sable violáceo
Scientific name
Campylopterus hemileucurus
Birds Cloud Forest · Forest Edge · Rivers & Streams · Tropical Rainforest

What Do Pico & Tati Think?

Pico: “It looked dark until it turned!”

Tati: “Iridescent feathers can change appearance as the light changes.”

Identification

Key Features of the Violet Sabrewing

  • Large hummingbird shape

  • Thick curved bill

  • White outer tail corners

Habitat & range

Humid mountain forest and forest edges on both slopes. Breeding is mainly at middle elevations, with seasonal descent into foothills. Guanacaste means humid mountain habitat, not dry beaches.

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.
