An Unusual Case Of Common Terns Nesting On A Rooftop In Ontario And An Attempt To Relocate The Colony, David J. Moore, Jeffrey N. Costa, Alexis L. Stupich
Ontario Birds
A variety of gull and tern species have adapted to urban environments by nesting on rooftops and other human-made structures. Previous reports of Common Terns (Sterna hirundo) breeding on rooftops have generally involved small numbers of nests (≤25). Here, we report an occurrence of an unusually large number of Common Terns nesting on a rooftop in Port Credit, Ontario, in 2013. A complete survey of the roof was conducted on 31 May, when 1,011 Common Tern nests were counted. A similar number of breeding pairs used this roof in 2014, but the site was largely abandoned by 2015, due to …

Changes In Agricultural Land Use And The Effectiveness Of Protected Areas: Impacts On The Occurrence Of Three Grassland Bird Species In The Carden Plain Of Ontario, Alice L. Merondun, Ginny Moore, Ron Reid, Erica Nol
Ontario Birds
We measure changes in occurrence (i.e., presence/absence) of three grassland bird species in the Carden Plain, between 2001 to 2005 and 2015 to 2016, by comparing point count results of the 2001–2005 Ontario Breeding Bird Atlas (OBBA) to repeated point counts at the same sites in the more recent period. We examine associations between changes of occurrence and habitat change and protection status of the survey locations for the three most commonly occurring species of Ontario grassland birds (Bobolink, Dolichonyx oryzivorus; Eastern Meadowlark, Sturnella magna; and Savannah Sparrow, Passerculus sandwichensis), all of which have experienced population declines in Ontario of …

Predator Exclusion Grids Protect Common Terns From Avian Nest Predators At Presqu’Ile Provincial Park, Lake Ontario, Jennifer M. Arnold, Stephen A. Oswald, Donald J. Tyerman, Michael J. Barker
Ontario Birds
Common Tern (Sterna hirundo) breeding populations in inland areas of North America have experienced significant declines, particularly in the Canadian waters of the lower Great Lakes. Once home to two-thirds of the Great Lakes population, Presqu’ile Provincial Park maintained only a small breeding colony of Common Terns from the 1970s to the early 2010s. In 2008, a research program was started to understand the population status of this colony. This involved close collaboration between faculty at Penn State University and Ontario Parks staff, and identified poor reproductive success at this site. Although many factors contributed to this poor reproductive success …

Spring Migration Phenology, Abundance And Behaviour Of Little And Bonaparte’S Gulls At Oshawa Second Marsh, Lake Ontario, Ontario, 1992–2022, Tyler Hoar, D.V. Chip Weseloh, David J. Moore
Ontario Birds
The Little Gull (Hydrocoloeus minutus) is a rare gull in most of North America; however, in spring it is relatively numerous at several sites in Ontario, as it migrates with its much more numerous relative, the Bonaparte’s Gull (Chroicocephalus philadelphia). The primary objective of this study was to document the spring migration phenology, abundance and behaviour of the Little Gull and the Bonaparte’s Gull at Oshawa Second Marsh (OSM), Ontario. Pursuit flights, roosting flights and migration departures by Little Gulls are also reported. The study took place from late March to late May, 1992–2022, at OSM. This site consistently hosted …

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

A Case Report On Meeting The Spiritual Need Of Intubated Conscious Patient, Mahuya Karmakar, Santhna Letchmi Panduragan, Faridah Mohd Said
Patient Experience Journal
Nurses are showing more interest in including spiritual health to prevent and treat illnesses. For patients who can speak may ask for their spiritual need to the health care provider. But for intubated patients it.s difficult to express such needs. Most of the time caregivers focus on the physical parameters only for intubated patients. Apart from physical symptoms these patients also experience a variety of bio-psycho-socio-spiritual sensations. Research has shown that spiritual therapies can reduce distress, assist in preparing the patient for end-of life care, and enhance overall wellbeing along with improving their quality of life. The purpose of this …

Patient Experience Journal
In Canada, emergency departments have a large number of patients with mental health and substance use concerns passing through their doors. Our research aim was to assess the impact that therapy dog visits may have for patients presenting with mental health and/or substance use concerns to an emergency department based in Saskatoon, Saskatchewan. Working alongside an active patient advisory group and community-based therapy dog program volunteers, our mixed method approach utilizing ethnography, surveys, and interviews showed that therapy dog visitation had a beneficial impact on both patients and staff, thus improving the overall patient experience. Our study displays how the …
