Sites - Important Bird Areas (IBAs)

General characteristics 

This EBA embraces all the mountains above c.2,500m throughout the Central Andean chain of Colombia and northern Ecuador, to south of the equator at around Ambato (c.130S). In Colombia, the Central Andes has a main ridge-line at c.3,000m with isolated peaks (and massifs) reaching greater altitudes throughout; consequently, the EBA is concentrated around a number of disjunct areas, namely Nevados del Huila, Ruiz and Tolima, Volcn Purac, Nevados de Cumbal and Chiles. In Ecuador, the EBA extends south to include the Cotacachi and Cayambe mountains, the mountains either side of the central valley (and Quito) and south to Cotopaxi, terminating at the break in the mountains caused by the Napo and Pastaza rivers. The Southern Central Andes (EBA 046) lies adjacent to the south.

The primary habitat is tropical upper montane evergreen forest and elfin forest. The Central Andean pramo (EBA 043) abuts these forest areas on all the same mountain massifs, but lies at higher altitudes. In a number of areas the Northern Central Andes is adjacent to (and may overlap with) the Ecuador-Peru East Andes (EBA 044), though that is a lower-altitude region.

Restricted-range species 

Most of the restricted-range birds occur at 2,000-3,650m, where they are all dependent on montane and cloud forest. All nine restricted-range species are found in various combinations on the highland massifs mentioned above. The ranges of three species continue south of the Napo in the montane forests of the Southern Central Andes (EBA 046).

Hapalopsittaca fuertesi is apparently confined to the Nevados del Tolima, Quindo and Santa Isabel, whereas the closely related H. amazonina is primarily a bird of the Andes in Venezuela (EBA 034), and the East Andes of Colombia (EBA 038), although the subspecies velezi is known from the Nevado del Ruiz near Manizales in this EBA and birds have recently been recorded in the northern Andes of Ecuador (R.Williams verbally 1997). Records of Hapalopsittaca parrots at the head of the Magdalena valley (on the east slope of the Central Andes in this EBA, and on the west slope of the East Andes, EBA 038) may also refer to H. a. velezi, although confirmation is needed (Collar et al. 1992). Grallaria gigantea has been recorded at a number of localities on the east slope of this EBA, with just two records extending its range south to the Southern Central Andes (EBA 046) (Collar et al. 1992, Krabbe et al. 1994). G. milleri is confined to the Nevado del Tolima-Ruiz area where it had gone unrecorded since 1942 until 1994 when rediscovered in the Ucumar Regional Park (Cotinga 1995, 3: 8-9). Birds which are almost certainly Moustached Antpitta G. alleni have been seen and tape-recorded in this EBA in Ecuador's Cordillera de Guacamayo (P. Coopmans in litt. 1995), and this would extend the range of the species currently treated as endemic to the Colombian inter-Andean slopes (EBA 040).

Threats and conservation 

The upper montane forests in this EBA (especially in the 2,000-3,200 m zone) have been subjected to widespread and severe deforestation during this and previous centuries to the extent that most, if not all, of the forest has been cleared in many areas . The forests continue to be felled as a result of agricultural expansion (including clearance for pasture), and further degradation is projected to continue (Collar et al. 1992, 1994). The poor state of the forest in this EBA is reflected by the fact that all of the restricted-range birds are considered either threatened or Near Threatened. The widespread (though localized) but threatened Yellow-eared Parrot Ognorhynchus icterotis (classified as Critical) and Golden-plumed Parakeet Leptosittaca branickii (Vulnerable) also occur in this EBA.

A number of Key Areas for the threatened birds have been identified in this EBA, including (in Colombia) Los Nevados National Park, Purac National Park, Ucumar Regional Park, Ro Blanco Watershed Reserve, Alto Quindo Acaime Natural Reserve and Caon del Quindo Natural Reserve (Wege and Long 1995). A number of other notable protected areas cover the montane forests of the EBA (many of these being the same areas protecting the Central Andean pramos) with Las Hermosas and Nevado del Huila National Parks (in Colombia), and Cayambe-Coca Ecological Reserve (in Ecuador) standing out as of primary importance (IUCN 1992a).
