Rapid evaluation of the birdlife at the Research, Postgraduate and Amazon Conservation Center (CIPCA), Napo province, Ecuadorian Amazon

Abstract

The Research, Postgraduate and Amazon
Conservation Center of the Amazon State University
is located on the eastern side of the Ecuadorian Andes
Mountains, covering an area of approximately 2840
hectares of primary and secondary forests. The aim of
the present investigation was an inventory rapid of birds
in strata of secondary forest and in strata of intervened
areas (silvopastoral and agricultural interventions).
Transect counts were made by observation and call
recordings to register the species, which were done
intensively during the months of April and May 2018.
A total of 94 species were recorded in both study areas
corresponding to 30 families, being the most abundant
Thraupidae (27.6%) and Tyrannidae (16%) which are
very common birds in intertropical zones. Secondary
forest strata were the most diverse with a Margalef
index of 10.5 and a Shannon index of 3.6. However, the
intervened area shows a greater abundance regarding
the number of individuals per species, perhaps due to the
presence of fruit tree species. Species in risk categories
were also determined according to International Union
for Conservation of Nature, resulting in 13 species
with high value for these categories, which should be
considered important for conservation programs.
