Special Research Programs
Black-throated Blue Warblers
While consistent migration monitoring data collection makes up the bulk of our day-to-day activities, we lead and contribute to various other research programs. PEPtBO conducts research with breeding birds in Prince Edward County, monitoring federally listed species-at-risk, and more, through collaborations with other organizations and institutions. These special banding programs and bird surveys contribute vital information about the ecology of migrating birds, breeding patterns, and conservation that are beyond the scope of our regular migration monitoring program.
Learn more about some of our ongoing research programs below.
Snow Bunting Banding
Snow Buntings are circumpolar Arctic specialists that complete incredible migrations each year. These 40-gram, sparrow-like songbirds breed in the high Arctic and migrate long distances to winter in the southern parts of Canada and the northern United States. Very early in the year, when there is still snow on the ground, Snow Buntings are often seen foraging in fields around Prince Edward County. They forage on weed and grass seeds during the winter, and congregate in agricultural fields or even on gravel roads where feed has been spilled.
Since 2024, PEPtBO has banded Snow Buntings at a location on private land where they are known to spend the winter, to monitor their populations and movements. Because they are Arctic specialists, they prefer to be outdoors in the cold winter weather. Unlike most songbirds, their entire life cycle is typically spent in snowy landscapes. To accommodate their needs during banding, we don’t bring them indoors like other birds, rather we use a mobile banding station! This causes cold hands for the banders, but happier Snow Buntings!
Banding Snow Buntings allows us to examine year-to-year trends in abundance, timing, and demographics. As well, we contribute to population monitoring through recaptures at our site and others within the Canadian Snow Bunting Network, a collaboration of citizen scientists and researchers.

Bobolink Banding
PEPtBO has engaged in standardized monitoring of Bobolink since 2008, a species at risk that breeds in open hay fields and grasslands. Bobolink have been experiencing rapid population decline due to habitat loss, particularly the clearing of pastureland and other grassland habitat, which makes them a species of interest for population monitoring. PEPtBO uses audio lures to attract the Bobolink to our site during their migration to be able to count their numbers and evaluate their demographics to monitor reproductive success of the species. We provide the data to ECCC to assist with status assessments to aid in the preservation of this species.
PEPtBO’s Bobolink protocol includes the operation of 6 nets from August 15 through September 10.

Owl Banding
PEPtBO has been operating a standardized owl monitoring program since 2001. The focus of our nighttime migration monitoring and research is the Northern Saw-whet Owl, one of North America’s most frequently banded owl species. The focus on this species is due to the fact that this strictly nocturnal owl is difficult to detect outside the breeding season, and also because of their migratory behavior, making them relatively easy to monitor through banding. Our nighttime migration monitoring program is part of Project Owlnet, which includes over 100 stations from across North America.
We operate 12 standard mist nets. These nets are opened 30 minutes after sunset and kept open for 4 hours as part of our standard protocol. We are exploring keeping the nets open 2 hours longer to see how this impacts the number of owls encountered.
The Northern Saw-whet Owl is the most frequently recaptured bird by foreign stations across North America, generally due to the audio lures used to attract them. This program allows the migratory routes and movement pattern of Northern Saw-whet Owls to be tracked both within a season and over many years due to the high recapture rate. Our station has foreign recoveries every year that have been banded in previous seasons, and it is not uncommon for the original banding date to be a few years prior.

Brown Creeper Ageing and Sexing
Some of the most important information we collect during banding is for calculating demographic rates, which contribute to our knowledge of population trends for conservation. This includes determining lifespans, how many males or females are in the population, and how many new birds are recruited into the population each year. For some species, it can be harder to determine the age and sex of an individual during banding. Each year, PEPtBO bands approximately 250 Brown Creepers, a tiny tree bark-coloured bird. As a high-volume station with skilled staff and well-equipped facilities, we have a unique opportunity to conduct research on this species.
We are currently developing methods for accurately ageing and sexing Brown Creepers in collaboration with Dr. Theresa Burg at the University of Lethbridge. Our research methods combine a variety of techniques, including DNA-based sex determination, standardized photography, and a variety of body measurements. Once the data is collected, we will use mathematical models to understand what traits we can use (such as bill length, patterns in the wing) to accurately age and sex Brown Creepers. While a guide to ageing methods already exists, we are testing the accuracy of these methods scientifically, and aim to publish these methods as a resource available to all banders.

Standardized Photography Lab
In our new photography lab, we are creating a standardized photo library of plumages and moult. While existing references like Pyle, the 700-page guidebook to banding birds in North America, provide detailed textual descriptions about ageing and sexing birds, most lack visual references.
Using a standard background and lighting, we quickly take photos of birds in pre-defined positions to create “digital specimens”. This allows us to learn even more about the birds after we release them. Each photo is paired with information about the bird that we collected when we had it in the hand: the species, date/time, the net it was caught in, its age, sex, fat, weight, wing length, and other information such as breeding evidence, health metrics, any biological samples, and its history of being recaptured over the season or even between years.
This library will provide an excellent resource for conducting future research and for helping banders to learn how to determine the age and sex of birds across a variety of species and plumage cycles. In the future, we hope to work with collaborators from research institutions to photograph birds for their project needs.

Funding Research
We know that these special research activities can result in outcomes with greater impact. However, as a non-profit organization, we incur greater costs due to increased numbers of nets, other research-related equipment, and personnel. Research programs at PEPtBO are funded by your donations. If you are interested in supporting a specific research program, please contact us.
