We report documented records of the Marañón Crescentchest (Melanopareia maranonica) in six localities. These have hydrological connectivity with the middle basin of the Marañón River, in the provinces of Celendín (Cajamarca) and Luya (Amazonas), Peru. The records were obtained through occasional encounters, biological evaluations and intensive searches, between 2017 and 2020. These new records are between 1111 and 2074 m in elevation, exceeding its known altitudinal range by more than 1000 m. A total of 39 individuals were registered (11 females, 12 males and 16 indeterminate due to the fact that only auditory registration was made). We expanded the known range with respect to the published records by 121 km in the Cajamarca region and 98.2 km in the Amazonas region. Appropriate habitat for this species is protected in 5,290.12 ha of the Marañón Seasonally Dry Inter-Andean Forest ...

Se evaluó la diversidad y distribución de la avifauna en dos gradientes altitudinales en los distritos de Utco y Balsas en los departamentos de Cajamarca y Amazonas al norte de Perú. En cada gradiente altitudinal se identificaron cuatro estratos en base al tipo de cobertura vegetal y altitud desde los 850 a 3427 msnm en Utco y de 845 a 3663 msnm en Balsas; evaluándose 160 puntos de conteo sin estimación de distancia en las áreas menos impactadas y con acceso factible; fueron establecidos 20 puntos por estrato, los registros se tomaron durante las 6:00 a 10:00 y 15:00 a 18:00 horas, cada punto fue georeferenciado y evaluado por 10 minutos; se aplicó la técnica de “Playback”, grabaciones de cantos para su posterior identificación y se utilizaron registros de observaciones asistemáticas; determinándose la diversidad alfa y beta. Se registraron 167 especies de las cuales 10 so...

Field observation records of Forpus xanthops are documented. Between 2013 and 2018, eight observations show F. xanthops feeding in various places in the seasonally dry tropical forest of the Marañón (BTES-Marañón) in Cajamarca and Amazonas. These records show that some items in their diet are cactus species, such as Espostoa lanata (Kunth) Britton & Rose, Espostoa mirabilis F. Ritte, Armatocereus rauhii Backeb, the latter two species being endemic to Peru. Feeding records include also Parkinsonia praecox (Ruiz & Pav.) Hawkins, Eriotheca discolor (Kunth) A. Robyns, Ochroma pyramidale (Cav. ex Lam.) Urb. and the fruit species Spondias purpurea L. and Citrus sinensis (L .) Osbeck.
