We report the presence of the Black-and-white Hawk-Eagle Spizaetus melanoleucus in the Allpahuayo Mishana National Reserve (AMNR) and at the same time we extend its range to the north of the Amazon river, increasing in the AMNR the richness of species to 498. We describe some details about the behavior of the species and the current state of conservation of the forests where the individuals were sighted.

Information about the abundance of paiche Arapaima gigas in natural environment in the Peruvian Amazon is very scarce, being greater the results obtained from fisheries management programs through monitoring in places where they have been used for commercial purposes. This work shows the results of annual monitoring between 2014 and 2017 in the area of Yarina, Pacaya river basin, in the Pacaya Samiria National Reserve (PSNR), where the paiche population is not homogeneous in the bodies of water, registering higher average density in the Yarina and Huama watercourses compared to the Zapote and Yarina lakes. Likewise, the low depth of the bodies of water registered in the Huama watercourse during 2017, influence the abundance of the adult individuals of paiche, but not of the juveniles.

De junio del 2009 a julio del 2010, en la Reserva Nacional Allpahuayo MishanaRNAM, ubicado entre el margen derecho de la carretera !quitos - Nauta y el margen izquierdo del río Nanay, Loreto- Perú, se llevó a cabo el presente trabajo de tesis cuyo objetivo fue estudiar los patrones de muda de la avifauna de dicha reserva. Para ello se realizaron 95 salidas al campo distribuidos en 11 meses, con reducidos días de colecta de enero a mayo por efecto de las abundantes lluvias, llegándose incluso a la ausencia de capturas en el mes de febrero; se utilizaron para las capturas redes de neblina y anillos metálicos para marcaje; capturándose· un total de 1556 individuos correspondiendo a 111 especies, incluidas en 30 familias y 28 órdenes. Los resultados muestran, en base al periodo estudiado, que el patrón de muda de la avifauna de la RNAM se encuentra asociado con las temporadas estac...

The urban and peri-urban area of the city of Iquitos is home to a considerable diversity of bird species, some of them little known and others that are adapting to the resources that the anthropic environment provides them. The inadequate management of green areas, added to other anthropogenic and climatic factors, would be having a negative impact on the composition and abundance of the avifauna, for which reason the present investigation sought to know the influence of anthropogenic and climatic factors on biodiversity and populations. of birds in the city of Iquitos. To this end, four areas of the city were sampled using the point-count technique, which allowed a total of 51,603 individuals distributed among 18 orders, 40 families and 125 species to be recorded, with the species Coragyps atratus, Brotogeris versicolorus and Columba livia being the ones that They had more sightings.
