Avifauna do Parque Estadual Lago Azul e possíveis dispersoras de Arecaceae, Campo Mourão, Paraná

Abstract

Are fundamental to the ecosystems, among them the Arecaceae, which are also widely used as a resource by birds. The present work aimed at surveying the avifauna present in Lago Azul State Park and also to verify which of these species act as possible dispersers of Arecaceae, besides recording the interaction of birds in four species of Arecaceae found in the Park. The work was carried out between January and May 2022. The bird surveys had a weekly frequency, totaling approximately 100 hours of sightings, by means of pre-established fixed points and linear transects along the Perobas Trail. Binoculars and a camera were used for the sightings. A total of 58 bird species were sighted, belonging to 13 orders and 28 families. Twelve species of Arecaceae are present throughout the Park, of which four species were observed andbirds visiting their fruits were recorded. The Turdidae and Ramphastidae family are considered good dispersers of Arecaceae, and were seen in the Park interacting with Arecaceae fruits, with this we can conclude taht dysweights are important in place.
