“…However, in the El Oro parakeets’ range, a similar upslope shift has been observed in an ecologically distinct species, the endangered and endemic Ecuadorian tapaculo ( Scytalopus robbinsi ). The Ecuadorian tapaculo is a dispersal-limited, insectivorous bird which seems to have undergone a 250 m upslope shift in its distribution range within the last 25 years [ 47 ]. The altitudinal shift of a similar magnitude among two ecologically distinct species suggests that the shift in the range of the El Oro parakeets is indeed driven by sensitivity to the temperature increase rather than to sensitivity to food availability, and is therefore a direct effect of warming temperatures.…”

In tropical montane cloud forests, climate change can cause upslope shifts in the distribution ranges of species, leading to reductions in distributional range. Endemic species with small ranges are particularly vulnerable to such decreases in range size, as the population size may be reduced significantly. To ensure the survival of cloud forest species in the long term, it is crucial to quantify potential future shifts in their distribution ranges and the related changes in habitat availability in order to assure the long-term effectiveness of conservation measures. In this study, we assessed the influence of climate change on the availability of forested habitat for the endemic El Oro parakeet. We investigated the future range shift by modelling the climatic niche of the El Oro parakeets and projecting it to four different climate change scenarios. Depending on the intensity of climate change, the El Oro parakeets shift their range between 500 and 1700 m uphill by the year 2100. On average, the shift is accompanied by a reduction in range size to 15% and a reduction in forested habitat to only 10% of the original extent. Additionally, the connectivity between populations in different areas is decreasing in higher altitudes. To prevent a population decline due to habitat loss following an upslope range shift, it will be necessary to restore habitat across a large elevational span in order to allow for movement of El Oro parakeets into higher altitudes.

“…It has not been found an abundance of the species selected in forest of Nothofagus with tolerant species, possibly due to their high fraction of coverage canopy and understory cover. Birds selected as potential habitat forests of A. araucana and Nothofagus spp., usually multi-structuraded with some coverage of the understory (Amico et al, 2008;Hermes et al 2017). less populated the sites with a high presence of shade-tolerant species.…”

Fragmentation and degradation of forest habitats affects (the susceptibility of several species is high) highly sensitive species, provoking a serious decrease in biodiversity. To deal with this problem it is necessary to consider the conservation level of bioindicator species and the development of a sustainable forest management of the natural resources. Within this framework, the current study poses the statistical binomial logit modeling to identify the potential habitat of endemic birds (Rhinocryptids) in rain forests in the south of Chile, biodiversity “hostpot” worldwide. The research allowed to identify a potential area of habitat of 14619 hectares with high probability presence of the studied birds. This area presented certain habitat constraints both topographic and vegetation factors. The studied birds showed a high selection of habitats associated to mixed forests of Nothofagus species, sites with high stratification and understory presence. The low quantity of Rhinocryptidae family species was associated to exclusive forests of Araucaria araucana, which exist at higher altitudes. The model of potential habitat of bioindicator birdlife (avifauna) within a system of geographic information it is presented as an efficient tool of information among the degree of alteration of ecosystems and for decision-makings in native forest management.

“…Its good conservation status has led to the realisation of several scientific studies in the reserve in the last few years in order to assess its biodiversity (e.g. Cogălniceanu et al 2015;Hermes et al 2016Hermes et al , 2018aSzékely et al 2016;Torres-Porras et al 2017;Betancourt et al 2018).…”

Private protected areas have recently attained more importance at a worldwide level as regards nature conservation. Particularly, the specific region of Western Ecuador receives hardly any protection from the State, and private reserves could, therefore, be a suitable tool to ensure the preservation of its forests and their associated wildlife biodiversity. In this work, we compare the bird species richness between private reserves and public protected areas (managed by the State) located in this region. We also show a checklist of bird species found in the Buenaventura Reserve, a private reserve located in south-western Ecuador. Our comparison shows that smaller private reserves may harbour a similar number of bird species than larger protected areas managed by the state, and they have a higher number of bird species per area. In particular, a total of 233 different bird species were registered in Buenaventura, which were distributed in 16 orders and 42 families. Three species were classified as endangered at an international level: El Oro Parakeet (Pyrrhura orcesi), El Oro Tapaculo (Scytalopus robbinsi), and the Grey-backed Hawk (Pseudastur occidentalis), and another three at a national level: the Long-wattled Umbrellabird (Cephalopterus penduliger), the Slaty-winged Foliage-gleaner (Philydor fuscipenne), and the White-vented Plumeleteer (Chalybura buffonii). Therefore, private reserves can be appreciated as a suitable conservation tool for bird conservation, and they should not be undervalued because of their smaller size. Buenaventura Reserve is a good example of how private reserves are extremely important in fragmented landscapes, as is the case with tropical forests in Western Ecuador.
