Levantamento avifaunístico da estação ecológica Olho D’água das Onças e arredores, no município de Picuí - PB.

Abstract

Fauna lists are fundamental in the analysis of species richness and distribution, logo are necessary for the definition of public policies for conservation and protection of natural resources. Without these, there are difficulties in proposing actions conservationists due to the irreversible and accelerated loss of biodiversity. Per this, the Brazilian Committee of Ornithological Records (CBRO) has been dedicated to periodic updates of the list of birds occurring in Brazil. Considering that the

Caatinga is identified as a domain with a high rate of endemism of southern birds. Americans, the present work sought to contribute to conservation actions, by

through the survey of the avifauna of the Olho D'água das Onças Ecological Reserve, located in Picuí, in Seridó Paraibano, an area with a lack of knowledge, to become a Private Natural Heritage Reserve. The research took place between March and August 2021, totaling 126 hours of sighting, with 27 hours per field/monthly. To carry out this, we opted for the method of observation in Points Fixed, using the ad libitum sense sampling technique or (Sampling of All the Occurrences). Registered birds were also classified according to their status of conservation through the IUCN Red List (International Union for the Conservation of Nature and Natural Resources). In addition, parameters were used such as: sighting frequency, sample richness, relative abundance, dominance and diversity in order to know the composition and size of the avifaunistic community of the studied area. Thus, 88 species were found, distributed in 15 orders and 32 distinct families and all of them are in a situation of Least Concern (LC), according to IUCN. According to the data obtained for richness of diversity, it was observed that the area is quite diverse, with almost a quarter of the recorded bird species in the Caatinga, being of extreme importance the conservation and protection of these animals, considering that birds are one of the groups that suffer the most direct impact due to the

anthropization, mainly taking into account the fact that the biome is if related to predatory extractive activities. So, by actually becoming a

Private Natural Heritage Reserve (RPPN) will contribute to the expansion of protected areas in the Caatinga domains, in the state of Paraíba and in Brazil. Besides ensure better resource management based on the safe management of fauna and flora to a possible development of sustainable activities aspiring to the livelihood of people residing in the community and surroundings.
