The Cordillera Occidental is the lowest in elevation of the three branches of the Colombian Andes. The average altitude is 2,000 m (6,600 ft) and the highest peak is Cerro Tatamá at 4,100 m (13,500 ft). The range extends from south to north dividing from the Colombian Massif in Nariño Department, passes north through Cauca, Valle del Cauca, Risaralda, Chocó, and Caldas Departments to the Paramillo Massif in Antioquia and Córdoba Departments. From this massif the range divides further to form the Serranías de Ayapel, San Jerónimo and Abibe. Only to recede into the Caribbean plain and the Sinú River valley.

The ocellated tapaculo is a large bird found in the northern Andes in South America. It is a highly distinctive tapaculo; traditionally united with its closest relatives in the Rhinocryptidae, this family is paraphyletic with the Formicariidae (ground-antbirds) but instead of merging the tapaculos with the ground-antbird family, recent sources tend to split the antpittas from the Formicariidae.
The Paramo Frontino salamander is a species of salamander in the family Plethodontidae. It is endemic to the Western Ranges of the Colombian Andes where it is known from the area of its type locality, Páramo Frontino. It is also known from the Colibri del Sol Bird Reserve near Urrao. both areas are in the Antioquia Department.
The gold-ringed tanager is a species of bird in the family Thraupidae, endemic to Colombia. It is a plump, relatively short-tailed Tanager with a distinctive gold ring around its face. It inhabits a narrow band of high-altitude cloud forest on the slopes of the western cordillera of the Andes, where it survives on a diet of fruit and insects. The bird is found in small numbers within a limited geographical area, and much of its breeding biology has yet to be described. It is considered a vulnerable species, threatened by habitat loss.
The multicoloured tanager is a species of bird in the family Thraupidae. It is endemic to the mountains of Colombia, and as of 2010 has been categorized as vulnerable (VU) by the IUCN.
The white-sided flowerpiercer is a fairly common and widespread species of Flowerpiercer. Flowerpiercers are a genus of birds within the Tanager family Thraupidae, with specially adapted bills that enable them to pierce the sides of flower blossoms to access the nectar. The white-sided flowerpiercer is found in Colombia, Ecuador, Peru, and Venezuela. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest.
The black flowerpiercer is a species of bird in the family Thraupidae of the order Passeriformes. The family Thraupidae is known for tanagers and other very similar species of birds, but it is still facing classification issues. The black flowerpiercer is found in Colombia, Ecuador, Peru, and Venezuela.
Farallones de Cali is a cluster of mountains in the West Andes of Colombia. It is located west of the city of Cali and gives rise to many of the rivers that provide water and electricity to Cali. The PNN Farallones de Cali encompasses 150,000 ha (580 sq mi) in the mountains as well as much of the Pacific slope and is an area of very high biodiversity. The average temperature ranges from 25 °C (77 °F) in the tropical foothills to 5 °C (41 °F) in the páramo. In this territory are located the district of Pichinde, Andes and Leonera, and two villages Penas Blancas and Lomas de la Cajita.

The Paramillo Massif is a mountain range of the Tropical Andes System, located at the northern end of the Cordillera Occidental range in Colombia.
The Northwestern Andean montane forests (NT0145) is an ecoregion on the Andes mountains in the west of Colombia and Ecuador. Both flora and fauna are highly diverse due to effect of ice ages when the warmer climate zones were separated and the cooler ones combined, and interglacial periods when the reverse occurred. Because the environment is hospitable to humans, the habitat has been drastically modified by farming and grazing since the Pre-Columbian era.
The Cauca Valley montane forests (NT0109) is an ecoregion in western Colombia. It covers the sides of the Cauca Valley, which runs from south to north between the Central and Western Ranges (cordilleras) of the Colombian Andes. The ecoregion is home to very diverse fauna and flora, due in part to its varied elevations and climates, in part to its position near the isthmus of Panama, the route along which North American species invaded South America and then diversified as they moved to the upper parts of the Andes. Little of the original habitat remains at lower levels, but higher up there are sizeable blocks of forest, some of which are protected.
The Farallones del Citará are situated in the mountains of southwest Antioquia, Colombia, only miles from the border with neighboring Chocó. The area contains two rivers, the Citará river and the Atrato river.
