Choco Tinamou

The Choco Tinamou (Crypturellus kerriae) is a ground-dwelling bird in the family Tinamidae, one of the most ancient lineages of birds, endemic to the humid lowland and foothill forests of the Chocó biogeographic region, occurring in western Colombia and just extending into eastern Panama. Tinamous are secretive, largely terrestrial birds related to ratites despite their ability to fly, and are known for their extraordinarily beautiful, haunting calls — rich, melodic whistles or flute-like notes that echo through forest interiors at dawn and dusk. The Choco Tinamou inhabits the floor and lower understorey of humid tropical forest, where it forages for fallen fruits, seeds, invertebrates, and fungi. Like other Crypturellus tinamous, it is very difficult to observe directly in the dense undergrowth but may be detected reliably by voice. Nesting is unusual among tinamous: males incubate eggs and care for chicks while females may mate polygamously with multiple males. The IUCN classifies the Choco Tinamou as Vulnerable, reflecting severe ongoing deforestation in the Colombian Pacific lowlands for cattle ranching, palm oil, logging, and human settlement, which has drastically reduced and fragmented its forest habitat.

Gray/Purple Heron

A large, elegant wading bird reaching up to 1 meter in height, gray herons inhabit wetlands, rivers, lakes, and coastal areas across Europe, Asia, and Africa. Patient, solitary hunters, they stand motionless for long periods before striking fish, frogs, and small mammals with lightning-fast dagger bill strikes. They nest colonially in tall trees in rookeries called heronries, sometimes shared with other colonial waterbirds. Widely distributed and of Least Concern globally.
