Snorkel Surveys: A Look Below the Surface
Sometimes the best way to assess a fish population is to become a fish…. or at least pretend to be one. Snorkel surveys are a sampling method sometimes utilized by fisheries biologists to enable them to peer into the underwater hidey holes which aquatic organisms call home. These surveys allow biologists to quantify the distribution, abundance, and composition of fish in an area, assess how they might be utilizing habitat, and understand more about their behavior. While other fisheries sampling methods such as electrofishing or trapping can be used, snorkel surveys require no fish handling and very little added stress to fish, making them a relatively low-impact alternative to more invasive sampling methods. While the other sampling methods such as electrofishing certainly play a role in the biologist’s toolbox, often snorkel surveys can be used to answer questions that may not be feasible to answer using other methods. Additionally, snorkel surveys have the added benefit of being very cost effective to perform over a large area of habitat.
Swallows of Alberta - Quick ID Guide
Although it may be easy to pick out the differences between these species when you’re comparing them on a page, it is much more difficult to accurately identify these birds in the field. The birds above are all swallows. From the family Hirundinidae, swallows are typically insectivorous and agile flyers (Sibley 2016, 305). There are six swallow species you can find throughout Alberta: Bank Swallows, Tree Swallows, Cliff Swallows, Barn Swallows, Northern Rough-Winged Swallows, and Violet-green Swallows (Sibley 2016, 306-309). The most common swallows, Bank, Tree, Cliff, and Barn Swallows, typically breed in North America and winter as far south as Argentina in the Cliff Swallow’s case (Sibley 2016, 306-309: Cornell University, 2024a). Here are some common ID tips you can use in the springtime, when these frequent flyers come around!
The Cheesy 2023 AJM Family Christmas Letter
We’re back with yet another cheesy Christmas letter from the AJM family! Against popular demand, we’ve unleashed another installment of our annual letter because apparently, we just can’t stop ourselves from talking about, well, ourselves. We promise that Chat GPT only wrote a small portion and it’s quite easy to tell which parts (hint: the jokes that aren't funny).
A friendly reminder to get lost in nature!
‘There just isn’t enough time in the day.” This is an oft heard justification why many people today can’t seem to find the time to get out and enjoy nature. Whether it’s rushing the kids to school or taking them to their extracurricular activities …
Here Be Dragons
Most AJMers would agree that one of the best parts of our jobs is spending time out in nature, getting the chance to see wildlife up close. We often focus on vertebrates, but it's hard to forget that the animal world is mostly insects when we visit a site as diverse and full of bugs as a wetland.
Welcome to AJM's New Headquarters!
In December 2022, AJM moved into its new headquarters in the Beltline of Calgary, AB. We are super excited to share a tour of our new digs. Check out the video below to see all the amazing features of our new home.
A Helping Hand: Updates to the Migratory Birds Regulations
Migratory birds are true global citizens. They do not recognize international borders, belong to a specific country, or call only one place home. Just as humans do, these birds follow good weather and food availability across great distances. In the spring and summer months, thousands of birds make the trip up to Canada to nest, mate, and raise their young.
The Not-So-Common, Not-A-Hawk
Each spring, as the ice begins to thaw, the forests, wetlands and prairies awaken to the sound of birdsong, brought by hundreds of migratory bird species arriving home to their summer breeding grounds.

Bathymetry: The Shape of Sound
Have you ever wondered what the bottom of the ocean looks like? Or how deep your favourite lake is? Using the science of bathymetry, we can investigate these mysterious biomes without ever leaving the surface! Bathymetry is the measurement of water depth in river, lake, and ocean ecosystems. It is a fundamental component of hydrography which studies the physical characteristics of a water body.
Species Spotlight: Long-toed Salamander
Under the cover of darkness, a small, sleek amphibian emerges from beneath ground cover. Part of the mole salamander family, the long-toed salamander (Ambystoma macrodactylum) is mostly nocturnal and spends much of its time hidden under rocks and woody debris in boreal habitats and montane basins …
Sounds, Like a Good Idea
lthough many of us have appreciated the melody of birdsong, the buzzing of insects, and the noises of wildlife, we might not realize just how unique and important these sounds are. Across the globe, scientists, naturalists, and wildlife aficionados tune into wildlife sounds to inventory species …
Who’s Who in That Pool?
As spring sweeps into Alberta, ice thaws, snow melts away, and seasonal rains and flurries fall, all across the province waterbodies fill and wetlands come to life. Many of us will turn our eyes skyward watching flocks of birds wing their way north from their winter refuges, but from under the fallen leaves, rocks, holes …
BONEFISH! TWELVE O’CLOCK!
AJM’s Fisheries Biologist, Hillary Keyes, recounts her recent adventures in Belize! The past few years in the month of March, you would have found me on a frozen Alberta lake with a tiny rod, jigging for any of our resident trout species or yellow perch, sometimes with a tip-up baited for northern pike nearby.
April Showers bring… April Flowers?!
Alberta is home to an impressive variety of flora and fauna. One of the fauna groups that often tends to get overlooked are amphibians. Amphibians are animals that have life stages that occur both aquatically and terrestrially. One of their most prominent features is their permeable skin that allows them to regulate moisture and gas exchange (breathing!). This awesome adaption also leaves them prone to impacts from pollution …

What the Duck? Why Waterfowl are Essential to Wetlands
Ord’s kangaroo rats are an amazing species, trust us, we could wax poetic for hours about their cute appearance and incredible adaptions. Instead, welcome to K-rat 101, an introduction to the wonderful world of Alberta’s nocturnal ninja. With no close relation to the invasive Norway rat, nor the leggy marsupials from Australia, the Ord’s kangaroo rat is part of a distinct group of rodents specially adapted to life in hot, arid environments.

Bull Trout Conservation - 'Tis the Season for Some Fish Squeeze'n!
For fisheries biologists, the month of September is an exciting one, as it marks the spawning season for many of Alberta’s Bull Trout populations. Bull Trout is Alberta's provincial fish and it is becoming a rare breed. Populations are considered "threatened" or of "special concern". Read AJM's latest blog to learn more about the species and how AJM is part of the BLTR conservation movement.
