Aspectos reprodutivos e dieta alimentar dos ninhegos de Rhinoptynx clamator (Aves: Strigidae) no campus Marco Zero da Universidade Federal do Amapá, Macapá-AP

Abstract

RESUMOEste trabalho tem como objetivo relatar os aspectos comportamentais de nidificação, alimentação e desenvolvimento dos ninhegos de Rhinoptynx clamator (Strigidae) em um fragmento florestal no Campus Marco Zero da Universidade Federal do Amapá. Apenas um ninho foi encontrado, no solo e na base de um tucumã Astrocaryum oleatum. Três ovos brancos com manchas marrons foram observados, cuja medida foi de 41 x 35 mm em média. A incubação durou 28 dias e foi efetuada pela fêmea, e o último filhote a nascer viveu apenas dois dias. Os filhotes sobreviventes foram medidos durante o seu desenvolvimento. Durante a estação reprodutiva foram coletadas algumas pelotas de regurgitação, sendo encontrados três tipos de vertebrados: Rattus sp., Micoureus cf. regina e Columbina talpacoti. PALAVRAS-CHAVE:Rhinoptynx clamator, Reprodução, Amapá. Nesting and diet of Rhinoptynx clamator (Aves: Strigidae) from Campus Marco Zero da Universidade Federal do Amapá, Macapá-AP ABSTRACTWe report nesting behavior, feeding and development of nestling of Rhinoptynx clamator (Strigidae) in a forest fragment on Campus Marco Zero of Universidade Federal do Amapá. The nest was located on the ground, close to a palm Astrocaryum oleatum and three eggs were observed. These eggs were white whit brown spots and measured 41 x 35 mm in average. Incubation was made by female and lasted 28 days and the last owlet died two days after born. The remaining birds were measured during its development. Feeding items includes Rattus sp., Micoureus cf. regina and Columbina talpacoti.

O olho da coruja-orelhuda: observações morfológicas, biométricas e valores de referência para testes de diagnóstico oftálmico

“…As corujas estão distribuídas em diversos habitats no mundo (Santos 1979, Sick 1993, Agillar 2003, exceto na Antártica, e são provavelmente originárias do Velho Mundo (Sick 1993, Aguiar & Naiff 2009. As corujas-orelhudas são encontradas na América do Sul, principalmente na Venezuela, Bolívia, Paraguai, Argentina, Uruguai e Brasil, tanto em áreas altamente arborizadas quanto em áreas urbanas (Sick 1993, Agillar 2003, Squarzoni et al 2010.…”

Owl Assemblages in Fragments of Atlantic Forest in Brazil

“…According to Murcia (1995), tree mortality increases along edges, which provides nesting sites for owls, and the density of dead trees has been found to be related to the richness of owl species that nest in dead wood (Boyle et al 2008, Pereira et al 2009, Pereira et al 2015. According to Aguiar & Naiff (2009), species of owls that prefer edges benefit from the fragmentation of forests and have even be recorded in more open landscapes such as in cerrado and caatinga. In the Atlantic Forest, some species of owls will use fragments as small as 400 x 30 m as nesting sites (Aguiar & Naiff 2009).…”

Taphonomic Analysis of Micromammal Remains from Striped Owl (Pseudoscops clamator) Pellets in Northeastern Buenos Aires Province, Argentina: Implications for Archaeological Sites Formation

“…It is found in diverse habitats from sea level to 1400 m asl, including xerophytic forests, jungles, grasslands and suburban areas (Marks et al ., ). Its diet is based mainly on rodents, and occasionally on birds, other vertebrates and insects (Massoia, ; Isacch et al ., ; Motta‐Junior et al ., ; Delgado et al ., ; Pautasso, ; Aguiar & Naiff, ; Lo Coco et al ., ). Most of the diet studies agree on the relatively large size of its prey items, in comparison with other South American Strigiformes, counting Holochilus spp.…”
