Peculiarities In The Appearance And Moult Of Long-Tailed Duck, Peter S. Burke, Tim Lucas, Kevin A. Mclaughlin Nov 2025

Peculiarities In The Appearance And Moult Of Long-Tailed Duck, Peter S. Burke, Tim Lucas, Kevin A. Mclaughlin

Ontario Birds

This paper reviews the literature on moults and resulting appearances of the Long-tailed Duck (Clangula hyemalis; LTDU), focusing on the high degree of plumage variation observed in this species, which is unique among ducks. In addition to exhibiting three visibly different plumages in its first year of life, and two visibly different plumages every year thereafter, the LTDU also shows a high variation among individuals, due, at least in part, to individual variation in the prolongation of each moult. This has led to confusion for those describing LTDU plumage and moult patterns in the past. Previous (and some erroneous) hypotheses …

Loafing And Sleeping Behaviour Of Trumpeter Swans, Harry G. Lumsden, Gerry Markhoff, Gary Lane, Allan Scott Nov 2025

Loafing And Sleeping Behaviour Of Trumpeter Swans, Harry G. Lumsden, Gerry Markhoff, Gary Lane, Allan Scott

Ontario Birds

An observational study of loafing and sleeping behaviour of Trumpeter Swans was conducted in southern Ontario throughout the year in 2018 and 2019. Like other birds, these swans have the ability to close down one brain hemisphere at a time during rest, which is indicated by eye closure. We quantified rates of closure of eyes during sleeping bouts for both breeding and non-breeding swans. Single eye closure varied in frequency, duration and in terms of which hemisphere was shut down. Increasing duration of eye closure over time indicated an increased sense of security with surrounding in one mated pair. Proportion …

Changes In Abundance Of Least Bitterns In Ontario,1995-2019, Michael J. Kirchin, Giuseppe E. Fiorino, Greg P. Grabas, Douglas C. Tozer Nov 2025

Changes In Abundance Of Least Bitterns In Ontario,1995-2019, Michael J. Kirchin, Giuseppe E. Fiorino, Greg P. Grabas, Douglas C. Tozer

Ontario Birds

Populations of many breeding marsh bird species continue to decline in the southern Great Lakes basin, although this is not the case for the threatened Least Bittern. Recent analysis based on data from the Great Lakes Marsh Monitoring Program of Birds Canada shows that its abundance has increased consistently since the mid-2000s throughout the lower Great Lakes in the U.S. and Canada, with the highest abundance occurring in recent years. In this study, we expanded on these findings by assessing patterns in abundance of Least Bitterns among different geographical locations in Ontario and across years from 1995 to 2019. We …


Common Gallinule Banding In Ontario, Ross W. Wood, Barbara A. Campbell, Shawn W. Meyer, Tore Buchanan Nov 2025

Common Gallinule Banding In Ontario, Ross W. Wood, Barbara A. Campbell, Shawn W. Meyer, Tore Buchanan

Ontario Birds

Between 2012 and 2017, we conducted a Common Gallinule banding study to determine the feasibility of catching and banding gallinule with an airboat in Ontario, estimate how many birds could potentially be banded and subsequently encountered, calculate an index of productivity and assess whether enough data could be obtained to inform management decisions and conservation planning. We captured gallinules using dip nets and spotlights at night from an airboat. In total, we banded 440 (approximately 28%) of the 1,564 gallinules that have ever been banded in Ontario. Five of our banded birds were subsequently encountered, four within Ontario and one …


Acoustic Sensing For Temple-Position Detection In Smart Glasses, Jay Lee Nov 2025

Acoustic Sensing For Temple-Position Detection In Smart Glasses, Jay Lee

Defensive Publications Series

The inertial measurement units (IMUs) that smart glasses use to detect open-or-closed status consume valuable space. This disclosure describes techniques to determine the open or closed status of smart glasses by using acoustic components such as microphone, speaker, etc. that are already present in smart glasses. Per the techniques, speakers located on both temples are caused to emit a pulsed sound inaudible to the human ear, e.g., an ultrasonic sound. A microphone in the nose pad picks up the specific frequency emitted by the speakers. When the temples are open and the device is worn on the head, the amplitude …


Permutable Prime Index, Priyesh Padmavilasom Nov 2025

Permutable Prime Index, Priyesh Padmavilasom

Defensive Publications Series

Permutable Prime Index (PPI) is a way to represent the permutability of digits in a prime number while maintaining the prime number property of those permutations. The index mentioned here is the ratio of total candidates, i.e. permutations that are likely prime to the ones that are actually prime.

UB Journal for Humanities

This study deals with the manifestations of the other (Jewish) in the novel ‘The Current Jew’ by the Yemeni novelist Ali Al-Muqri, and this topic acquires great importance reflected in shedding light on this novel, in which the novelist combined the social dimension and literary enjoyment, and the study also represents a social message, because it is concerned with revealing a realistic issue that affects Yemeni society in particular. The research relied on the social approach that focuses on linking literature to society, considering that the novel in its origin is a literary work that deals with the social and …
