Dr. Erin Bayne

Dr. Erin Bayne

DirectorUniversity of Alberta

Erin’s research centers on understanding the cumulative ecological impacts of human activities on biodiversity. We combine ecology with cutting edge techniques in wildlife monitoring, survey design, geographic information systems, and habitat modelling. Our goal is to provide recommendations on how biodiversity reacts to various types of human and natural disturbance with the goal of achieving better conservation outcomes. Erin, along with the help of many undergraduate and graduate students are continually working to improve monitoring methods in an effort to increase efficiency and statistical precision.

Data Processing CoordinatorUniversity of Alberta

Alex’s responsibilities include overseeing the processing of acoustic data and coordinating fieldwork in boreal Alberta. He’s been involved with the project since the pilot study, investigating wetland bird species, owls, bats and amphibians. Alex divides his time between deploying ARUs across the boreal in the early spring into late summer, and listening to and interpreting the acoustic data in the fall and winter.

Use of an acoustic location system to understand songbird response to vegetation recovery on reclaimed wellsites.

The objective of this project is to demonstrate the potential of an acoustic location system to collect data on songbirds as functional measure of wellsite recovery following reclamation. An acoustic location system is an array of microphones which can be used to estimate the location of a signal using time of arrival differences determined between channels. The comparative use of wellsites and adjacent forest by the songbird community, and behaviour of Ovenbirds surrounding the wellsite will be examined. Information from this study will be used to gain insight into the legacy of wellsite disturbances in the boreal on songbirds.

Using remote cameras and autonomous recording units to monitor impacts of human footprint on large mammal biodiversity in Alberta, Canada

My research is focused on studying the impacts of human footprint on large mammal biodiversity and adaptation to human presence. Much of the boreal landscape and soundscape has been altered in recent years due to expanding industrial and recreational activity. As such, I am examining patterns of large mammal habitat use in Alberta’s northeastern boreal via remote cameras and autonomous recording units (ARUs) across areas of varying human impact.

Understanding why certain songbirds are more or less tolerant to chronic industrial noise

My PhD research is focused on understanding how songbirds are dealing with chronic industrial noise in the boreal forest, evaluating vocal plasticity to determine if this can explain why some species can persist in noisy areas while others avoid such areas. For this, I’m measuring vocal features from recordings of songbirds with territories in noisy and quiet areas. Additionally, I will relate vocal features with beak morphological measurements since beak morphology has been related with variability in vocal performance for passerine birds.

Using bioacoustics to examine the effects of energy development on owls

For my PhD research I’m working on determining the effects of disturbance from energy development on several owl species (Barred Owls, Boreal Owls, and Great Horned Owls) in the boreal forest of northeastern Alberta. I’m specifically interested in the impacts of industrial noise and the physical footprint of energy infrastructure on owl occupancy and habitat use. To get at this, I’ve surveyed for owls using autonomous recording units (ARUs) to detect owls calling in the spring at sites with and without industrial noise sources and in areas with varying amounts of physical disturbance to the landscape, and I’m processing the recordings using a combination of human listening and automated computer recognizers.

Songbird responses to wildfire severity and time since fire in the northern boreal forest

I am studying how songbird communities respond to wildfire in the Northwest Territories. I am looking at how burn severity affects songbird abundances and community composition in two large, recent burns. In a larger region where wildfires have occurred over several decades, I am looking at how bird communities differ in forests in varying stages of regeneration.

Singing behaviour and spring arrival date as indicators of breeding status and habitat quality in the Olive-sided Flycatcher

My research contributes to applied avian conservation by testing methods to monitor breeding success and measure habitat quality for a species at risk songbird, the Olive-sided Flycatcher (OSFL). I use Acoustic Recording Units (ARUs) and automatic recognition software to measure aspects of singing behaviour, such as song rate and amount of time spent singing and relate it to a male bird’s breeding status (single, paired, incubating, feeding young). I am also investigating the spring arrival times of OSFLs by comparing the first date of detection across a large latitudinal gradient to determine if habitat selection drives local spring arrival timing. My field research is conducted in the boreal forest of the Northwest Territories, northern Alberta and the Yukon.

Disentangling habitat use of Common Nighthawks in the boreal forest

My PhD thesis uses bioacoustics to understand the importance of different habitat functions for understanding Common Nighthawk habitat use in the boreal forest. The Common Nighthawk is a nocturnal bird species of conservation concern, and is thought to spatially and functionally explicit habitats, which complicates the construction of habitat models for conservation management. I use variation in acoustic signals to infer behaviour, which can be used to differentiate breeding habitats from other habitat functions. My thesis incorporates novel uses of signal recognition technology and citizen science data.

Sound localization for acoustic monitoring of bird populations in response to fire and oil extraction

My research will use sound localization technology to assess the impact of energy sector activity on birds. Understanding how birds respond to anthropogenic disturbances such as well sites is critical for evaluating impacts of energy development and for improving industry practices. Sound localization is a method for estimating the precise location of a singing bird. Using this technology to track bird movements can reveal how birds perceive and respond to disturbances. By collecting localization data at well sites in various habitats and at different stages of reclamation, my research will pinpoint reclamation practices that increase habitat recovery. The research will focus on species of conservation concern like Rusty Blackbirds and Yellow Rails, for which there is a recognized deficiency in our understanding of how they are affected by industrial activity.

Assessing the effects of understory protection harvesting on songbird communities in Alberta using autonomous recording units

My MSc research centered around the use of ARUs to conduct standard point count surveys in areas harvested through a technique known as understory protection. Understory protection harvesting effects on songbirds had not yet been assessed, and I showed that many species prefer this harvesting technique to traditional clearcutting. Furthermore, many species begin recolonizing understory protection areas within a decade after harvesting, whereas those species may not return to clearcuts for up to 100 years after harvest. I have also been a listener for the Bioacoustic Unit for the past 5 years.
