Parrots of the Wild
\"Parrots of the Wildis an exhaustive compendium of information about parrots, from their evolutionary history to their behavior to present-day conservation issues. A must-have for anyone interested in these amazing creatures.\" -Irene M. Pepperberg, Professor at Harvard University and author ofAlex & Me: How a Scientist and a Parrot Discovered a Hidden World of Animal Intelligence-and Formed a Deep Bond in the Process\"If you like parrots then you'll love this book. From their evolutionary past to their modern-day love lives,Parrots of the Wildpresents a suitably captivating read. I thought I knew a lot about parrots--until I delved into these pages.\" -Tony Juniper, author ofWhat Has Nature Ever Done for Us?andSpix's Macaw: The Race to Save the World's Rarest Bird
Parrots of the Wildexplores recent scientific discoveries and what they reveal about the lives of wild parrots, which are among the most intelligent and rarest of birds. Catherine A. Toft and Tim Wright discuss the evolutionary history of parrots and how this history affects perceptual and cognitive abilities, diet and foraging patterns, and mating and social behavior. The authors also discuss conservation status and the various ways different populations are adapting to a world that is rapidly changing. The book focuses on general patterns across the 350-odd species of parrots, as well as what can be learned from interesting exceptions to these generalities.A synthetic account of the diversity and ecology of wild parrots, this book distills knowledge from the authors' own research and from their review of more than 2,400 published scientific studies. The book is enhanced by an array of illustrations, including nearly ninety color photos of wild parrots represented in their natural habitats.Parrots of the Wildmelds scientific exploration with features directed at the parrot enthusiast to inform and delight a broad audience.

Taxonomic Diversity of the Quill Mites of the Family Syringophilidae
The quill mite fauna of the family Syringophilidae Lavoipierre, 1953 (Acariformes: Prostigmata) associated with parrots (Aves: Psittaciformes) are reviewed. Seven new species are described: Pipicobia cyclopsitta Marciniak-Musial, Hromada & Sikora sp. nov. from the Double-Eyed Fig-Parrot Cyclopsitta diophthalma in Papua New Guinea; P. fuscata Marciniak-Musial, Hromada & Sikora sp. nov. from the Dusky Lory Pseudeos fuscata in Papua New Guinea; P. tahitiana Marciniak-Musial, Hromada & Sikora sp. nov. from the Blue Lorikeet Vini peruviana in Tahiti (French Polynesia); P malherbi Marciniak-Musial, Hromada & Sikora sp. nov. from the Malherbe's Parakeet Cyanoramphus malherbi in New Zealand; Lawrencipicobia eclectus Marciniak-Musial, Hromada & Sikora sp. nov. from the Eclectus Parrot Eclectus roratus in Papua New Guinea; Neoaulobia pseudeos Marciniak-Musial, Hromada & Sikora sp. nov. from the Dusky Lory Pseudeos fuscata in Papua New Guinea; and N. Skorackii Marciniak-Musial, Hromada & Sikora sp. nov. from the Eastern Rosella Platycercus eximius in Australia.

Integrating citizen-science and planned-survey data improves species distribution estimates
Aim Mapping species distributions is a crucial but challenging requirement of wildlife management. The frequent need to sample vast expanses of potential habitat increases the cost of planned surveys and rewards accumulation of opportunistic observations. In this paper, we integrate planned‐survey data from roost counts with opportunistic samples from eBird, WikiAves and Xeno‐canto citizen‐science platforms to map the geographic range of the endangered Vinaceous‐breasted Parrot. We demonstrate the estimation and mapping of species occurrence based on data integration while accounting for specifics of each dataset, including observation technique and uncertainty about the observations. Location Argentina, Brazil and Paraguay. Methods Our analysis illustrates (a) the incorporation of sampling effort, spatial autocorrelation and site covariates in a joint‐likelihood, hierarchical, data integration model; (b) the evaluation of the contribution of each dataset, as well as the contribution of effort covariates, spatial autocorrelation and site covariates to the predictive ability of fitted models using a cross‐validation approach; and (c) how spatial representation of the latent occupancy state (i.e. realized occupancy) helps identify areas with high uncertainty that should be prioritized in future fieldwork. Results We estimate a Vinaceous‐breasted Parrot geographic range of 434,670 km2, which is three times larger than the “Extant” area previously reported in the IUCN Red List. The exclusion of one dataset at a time from the analyses always resulted in worse predictions by the models of truncated data than by the Full Model, which included all datasets. Likewise, exclusion of spatial autocorrelation, site covariates or sampling effort resulted in worse predictions. Main conclusions The integration of different datasets into one joint‐likelihood model produced a more reliable representation of the species range than any individual dataset taken on its own, improving the use of citizen‐science data in combination with planned‐survey results.

Design and Experimental Comparison of PID, LQR and MPC Stabilizing Controllers for Parrot Mambo Mini-Drone
Parrot Mambo mini-drone is a readily available commercial quadrotor platform to understand and analyze the behavior of a quadrotor both in indoor and outdoor applications. This study evaluates the performance of three alternative controllers on a Parrot Mambo mini-drone in an interior environment, including Proportional–Integral–Derivative (PID), Linear Quadratic Regulator (LQR), and Model Predictive Control (MPC). To investigate the controllers’ performance, initially, the MATLAB®/Simulink™ environment was considered as the simulation platform. The successful simulation results finally led to the implementation of the controllers in real-time in the Parrot Mambo mini-drone. Here, MPC surpasses PID and LQR in ensuring the system’s stability and robustness in simulation and real-time experiment results. Thus, this work makes a contribution by introducing the impact of MPC on this quadrotor platform, such as system stability and robustness, and showing its efficacy over PID and LQR. All three controllers demonstrate similar tracking performance in simulations and experiments. In steady state, the maximal pitch deviation for the PID controller is 0.075 rad, for the LQR, it is 0.025 rad, and for the MPC, it is 0.04 rad. The maximum pitch deviation for the PID-based controller is 0.3 rad after the take-off impulse, 0.06 rad for the LQR, and 0.17 rad for the MPC.

Deciphering the Parrot’s Voice: Satō Haruo’s “Okāsan” Magazine
Satō Haruo's \"Okāsan\" (\"Mother\") is a story that was published in Josei (Woman) magazine in October 1926. The plot follows \"I\" as he listens to the words of the parrot he bought from the pet store and deduces and fantasizes freely about her previous home. In this paper, I spotlight the fact that the home that \"I\" envisions through the voice of the parrot, Laura, corresponds to the family image that was being presented concurrently in Josei magazine and showcased that the ideal family was simply nothing more than an ideal. In relativizing Josei's familial discourse, and in this relationship between the published magazine and the story, I argue for the latter's importance.
