“…The first vocalization was recorded on 20 October and consisted, as reported by Costa et al. (:374), “… of a series of hooting notes, the first note being slightly longer than the remaining hoots and the whole song decreasing in frequency.” Similar vocalizations were recorded from 21 to 28 October. All calls were uttered between 21:30 and 05:22.…”

“…Unlike other potoos, Rufous Potoos, when threatened, begin to move in a slow, rocking motion resembling the swinging of a hanging leaf, or a leaf trapped in vine tangles (Solano‐Ugalde , Costa et al. ). Finally, another behavior that may help reduce the likelihood of predation is the pattern of defecation by the nestling Rufous Potoo, as in other potoos (e.g., Common Potoos; Skutch , Cohn‐Haft ), maintaining a clean area around the base of the nest tree by a vigorous ejection of feces 30–50 cm from the nest.…”

Notes on the breeding biology of Rufous Potoos (Nyctibius bracteatus) in lowland Ecuadorian Amazon

Five species of potoos occur in Ecuador, with Rufous Potoos (Nyctibius bracteatus) being one of the least known. We monitored a nest site of Rufous Potoos in a lowland forest in the Ecuadorian Amazon and provide information about the behavior of a nestling and one or more adults. Observations were conducted opportunistically from 10 August to 10 September 2018, and an infrared heat-and-motion activated camera was used to monitor the nest site from 11 September to 13 November 2018. We recorded 2006 10-s videos of the nestling and/or adult(s) that we used to quantify behavior. The nestling spent most of its time perching (53%) and stretching (20.7%). Beginning when~23 d old, the nestling began exercising its flight muscles and did so with increasing frequency over time. Adult behaviors included perching while brooding the nestling (55%), stretching (24%), flying (10.4%), and feeding the nestling (10.4%). The duration of the nestling period,~2 mo, in our study was similar to that reported previously for this species. Our observations suggest that the breeding and nestling behavior of Rufous Potoos is similar to that of other Nyctibius species. However, additional studies are needed to better document the behavior of Rufous Potoos during the incubation period. RESUMEN.Notas sobre la biolog ıa reproductiva del Nictibio Rufo (Nyctibius bracteatus) en bosque de tierras bajas ecuatoriano Cinco especies de Nictibios ocurren en el Ecuador, siendo el Nictibio Rufo (Nyctibius bracteatus) uno de los menos conocidos. Monitoreamos un nido de Nictibio Rufo en un bosque de tierras bajas en la Amazon ıa ecuatoriana y reportamos informaci on acerca de comportamiento del polluelo y uno o m as adultos. Se realizaron observaciones de manera oportunista desde 10 agosto hasta 10 septiembre 2018 y, se utiliz o una c amara trampa desde 11 septiembre hasta 13 noviembre 2018 para monitoreo del nido. La c amara registr o 2006 videos de 10-seg del polluelo y/o adulto(s) que fueron usados para cuantificar comportamiento. El polluelo pas o la mayor parte del tiempo perchado en el arbol (53%) y estir andose (20.7%). A los~23 d ıas de edad, el polluelo comenz o a ejercitar los m usculos de vuelo, incrementando en frecuencia con el tiempo. Los comportamientos de adultos incluyen perchado en el arbol mientras empolla (55%), estiramiento (24%), vuelo (10.4%) y alimentaci on del polluelo (10.4%). La duraci on de los per ıodos de crianza, 2 meses, en nuestro estudio fue similar a lo reportado anteriormente para la especie. Nuestras observaciones sugieren que la anidaci on y comportamiento del polluelo de Nictibio Rufo es similar a otras especies de Nyctibius. Sin embargo, estudios adicionales son necesarios para entender de mejor manera el comportamiento de Nictibios rufo durante el per ıodo de incubaci on.

“…Rufous Potoo is the smallest potoo (21-25 cm) and is restricted to the Amazon lowlands, from western Amazonia east to the Rio Tapajós (Cohn-Haft 1999, Solano-Ugalde 2011. Molecular studies revealed that N. bracteatus represents the oldest lineage in the family (Brumfield et al 1997, Braun & Huddleston 2009, Costa 2014, White et al 2017 and, due to its unique morphological and behavioural characteristics, a monotypic genus Phyllaemulor has been erected to accommodate the species (Costa et al 2018). Despite being the only understorey potoo (Ingels et al 2008, Cleere 2010, which might make N. bracteatus easier to observe, its breeding ecology is poorly known, and few published data are available on even basic aspects of the species' natural history (Cohn-Haft 1999, Cleere 2010, Solano-Ugalde 2011.…”

Outstanding issues in the study of antipredator defenses

Protective defense mechanisms are well documented across the animal kingdom, but there are still examples of antipredator defenses that do not fit easily into the current conceptualization. They either fall within the intersection of multiple mechanisms or fail to fall neatly into pre‐existing categories. Here, using Endler's predatory sequence as a framework, we identify problematic examples of antipredator defenses, separating them into protective mechanisms that are difficult to classify and those which act sequentially depending on context. We then discuss three ways of improving underlying terminological and definitional problems: (1) issues with English and polysemy, (2) overlapping aspects of similar mechanisms, and (3) unclear definitions. By scrutinizing the literature, we disentangle several opaque areas in the study of protective defense mechanisms and highlight questions that require further research. An unclear conceptual framework for protective defense mechanisms can lead to misconceptions in understanding the costs and benefits of defenses displayed by animals, while interchangeable terminologies and ambiguous definitions can hinder communication in antipredator studies.
