Executive summary

Mountain grackle (Macroagelaius subalaris) and Chestnut bellied hummingbird (Amazilia castaneiventris) this two species most endangered birds species in the world.  Has been identified this species is endangered mainly due to habitat destruction, natural history and ecological requirements is unknown. These threats increase the vulnerability of its remaining wild populations. The successful development and implementation of conservation plans for managing keystone or endangered species and their habitats ultimately depend on field data that describe their behavioral ecology, population structure. This project aims to assess the population status of populations of  A. castaneiventris and M. subalaris at eastern andes  (Colombia) and continue the study on the effects of habitat destruction on their behavioral and ecology at eastern andes  Colombia. We will use point count distance sampling method to estimate the population densities and structure the populations the  M . subalaris and A. castaneiventris we will also focus on describing the activity patterns, diet, natural history and songs.

We expect to identify the population status of this two endangered birds at our proposed research areas in order to design the most appropriate conservation strategies to preserve them. Finally, this project will train several local students and biologists in several methods for the study of icterids, tanagers, grackles and hummingbirds in the wild, in order to create a stronger and more qualified “team” that will direct field conservation efforts in Colombia and the Neotropic in birds.

Introduction and project description conservation Chestnut Bellied Hummingbird (Amazilia castaneiventris) and Colombian Mountain Grackle (Macroagelaius subalaris)

The main purpose of the here proposed project is to continue with our ongoing efforts towards the conservation of M. subalaris and A. castaneiventris in localities the eastern Cordillera of Colombia.  Thus, we are committed to identifying areas where wild populations of these birds still remain, and evaluate their population densities and structure. These data will provide the criteria towards were to focus future conservation efforts that will allow us to preserve viable populations of this two birds in the wild. We are also committed to continue our on-going research on the effects of habitat destruction of the behavioral ecology of Mountain Grackle and Chestnut bellied hummingbird through the direct comparison of the diet, activity budgets, social behavior of groups (Macroagelaius subalaris) living in fragmented and intensively logged Andean Oaks and dry forest to those living in continuous and less intervened areas at one of our study sites: Eastern Andes from Colombia

The proposed research is a “key” component for the development of a successful conservation action plan for M. subalaris and A. castaneiventris (that is currently being developed), by providing the first in-situ data on the status of wild populations.

This project will also give continuity to our efforts to provide opportunities for young local biologists and ecologists to develop their academic and professional careers in areas related to conservation biology. Only through the enhancement of a strong team of local researchers and professionals devoted to conservation in Colombia, will we be able to develop large-scale (and long-term) conservation strategies in this Mega-diverse country, in the near future.

 Symposiums and presentations will held in local schools to promote the student towards the participation in the project activities, with focusing on the importance of the area and your birds.
