Every Wild Life Matters

The crow seen in the above photo was admitted to AIWC near the end of May 2017 after being found in a northeast Calgary backyard, unable to fly.

AIWC staff are unsure what happened to the crow. He suffered a fracture to his right humerus and right radius.

The crow underwent surgery at AIWC and is receiving regular physiotherapy with staff. He will recover at AIWC’s facility until he is well enough to be released into the wild.

Crows, which are part of the corvidae family, have often been seen a nuisance due to their abundance, loud calls and fearless manner. However, these highly intelligent birds are actually beneficial to humans as they consume large quantities of insects and pests (“Crows & Magpies”). For more information on the ingenuity and intelligence of crows, see

AIWC operated on the tenet that “every wild life matters”, no matter how small or common the animal may be. Each creature found in our province plays an important role in Alberta’s ecosystems.

In 2016, AIWC treated 1,889 wild animals and helped hundreds more by assisting the public with wildlife-related issues. AIWC welcomes wildlife of all sizes and prevalence, from crows to moose calves.

Birds of a Feather: Some of Alberta’s Most Common Bird Species

They’re tapping at our windows, singing us morning songs and tantalizing Alberta’s felines, but who exactly are these little feathered friends? Aside from the obvious red-breasted robins or black-capped chickadees, how much do you know about Alberta’s most common birds?

Below is a brief introduction to Alberta birds! Be prepared to wow your friends with your bird knowledge!


House sparrow: House sparrows are chunky with full chests, rounded heads and stout bills. Males have gray heads, white cheeks, black bibs and reddish-brown necks, while females are a more dull brown. These sparrows are noisy and come out of their nest holes to pick at crumbs or seeds. They’ve been tolerating humans for centuries and are now quite comfortable hanging out on city streets, zoos, parking lots or more.

American tree sparrow: These plump little sparrows keep busy in the winter months, hunting for seeds, weeds and grass heads. In the springtime, these little sparrows head even further north to their breeding grounds in the tundra. You will recognize an American tree sparrow by his rusty cap and eyeliner on a gray, chubby-looking body.

White-throated sparrow: These are flashy little sparrows with spunk to match. They have black and white striped heads, bright white throats and yellow between the eye and bill. To identify a white-throated sparrow, look for a prominent bill, long legs and a narrow tail. You’re most likely to find these little sparrows in wooded area and forest edges. In the winter, they often nest in parks and woodsy suburbs.


Black-capped chickadee: No one can resist these undeniably adorable little birds. Black-capped chickadees have tiny bodies, oversized heads and big eyes. With a black cap and bib, this chickadee is easy to find and is usually happy to investigate people while searching out seeds, berries and birdfeeders. Often nesting in birch or alder trees, black-capped chickadees stay in Alberta year round.

Boreal chickadee: You aren’t likely to find one of these brown-capped chickadees in Southern Alberta. They are one of the only birds that live completely within the biome of the northern boreal forest. They have brownish caps and bibs and white cheeks.


House finch: The house finch has a bright red head and breast with brownish wings and body. Even if you’ve never seen one of these little finches, you’ve probably heard them! Their long, twittering song is heard in neighbourhoods around North America. These little birds are cheerful and like to frequent birdfeeders, just like the little chickadees! They are hardy birds too, happy to make homes in urban and rural areas or in their native habitats of deserts, grasslands and open forest.

Purple finch: You’re most likely to see one of these strawberry-coloured finches in the winter, when they come by to feed from birdfeeders. It’s easy to mix them up with the house finch, but look closely at their colouring and you’ll notice that the red-pink of their faces mixes into the brown and white of their bodies in an almost ombré-toned manner.


Red-breasted nuthatch: These are active, hoppy little birds that make a “yank-yank” sound as they search tree bark for hiding insects. These tiny nuthatches have short tails, a plump body and almost no neck! They are blue-gray in colour with black caps, white stripes above their eyes and a rusty-red underbelly. Look for these bubbly little birds among spruce, fir, pine, hemlock, and poplar trees.

White-breasted nuthatch: Like their red-breasted friends, these nuthatches are full of energy, springing through backyards as they search for bountiful birdfeeders. Do you wonder how the nuthatches got their name? They like to take large nuts and acorns and ram them against trees until the seeds “hatch.” That’s exactly what you can find these black, blue-gray and white nuthatches doing along woodland edges.

Now that you have a very brief introduction to the types of feathered backyard visitors in Alberta, you can share your knowledge! The more you learn about the beautifully diverse, intricate species that inhabit our province, the more you will appreciate the natural world.

Ducklings and Goslings, Oh My!

Is there anything more endearing than a baby bird? Whether it’s a fluffy yellow-brown duckling, a waddling gosling or even a wide-eyed owl baby, baby birds have a soft spot in every wildlife lover’s heart. And with the blooms and greenery of spring come the birth of wildlife babies around Alberta.

AIWC has been receiving plenty of calls lately about ducklings and goslings.

Ducklings and goslings can be stranded for a number of reasons such as late hatching, injury, human/pet interference or simply getting lost.

Here are some tips in case you come across one of these baby birds:

Look for Mom! Female ducks tend to stay close to their babies and Mom could be nearby. If possible, it’s always best to leave babies with Mom because she knows exactly how to care for them. If you’re wondering whether or not the baby is flying solo, remember that ducklings stay under their mother’s care until they are ready to fly. If you observe a gosling or duckling alone for more than 45 minutes, the babies could be in trouble. Call AIWC.

It’s okay to move a baby duck that is injured or in danger. The mother duck will not reject the baby because of human scent.

Orphaned ducklings need professional care, right away. They can die from the cold because they can’t generate their own body heat. Keep in mind that ducklings are fragile and can be easily injured or bruised if mishandled. They are very fragile! Call AIWC!

Unlike geese, ducks won’t adopt lone ducklings. Ducks recognize their babies by sound and will notice the outsider. If you are holding a duckling that is “peeping” a mother duck should come running up right away!
(Geese on the other hand are fine with accepting new babies and don’t seem phased by the additions! In fact, AIWC volunteers have rescued and rehomed 46 geese and goslings this year).

Always remember that if a duckling or gosling’s parents are near by, you need to leave the baby where you found it.

It’s always okay to call AIWC for advice in any wildlife situation. For more information on how you can support AIWC, visit

Poisons and Predators

This blog post is inspired by a recent bald eagle patient who was admitted to AIWC due to lead poisoning. I want to explore the different reasons behind how and why wildlife can become poisoned.

Some birds of prey die from secondary poisoning after feeding on waterfowl or deer containing lead shot as a result of ingestion or hunting (Government of Canada 2013, FWS 2015). Although lead bullets are banned across Canada, they are still widely used today (Gladue 1999, Government of Canada 2013, Williams 2017). Many of the lead shots that are fired don’t actually hit the intended target, and end up in the surrounding environment (Gladue 1999).

What happens to the lead once it ends up in the soil or a waterbody? It can accumulate in the tissues of living organisms and act as a poison to some species.

Bioaccumulation (also known as bioconcentration) is the effect whereby some metals and chemicals occur in higher concentrations in living organisms than they do in the surrounding environment, such as the water or soil (Freedman 2007).

Biomagnification (also known as food-web magnification) is the effect whereby top predators or species higher up in the food chain have higher concentrations of these metals and chemicals in their tissue (Freedman 2007).

Metals and chemicals that bioaccumulate tend to be absorbed and stored in the fat of the animal that consumes them, rather than excreted. The higher up on the food chain an animal is, the more organisms the animals may eat that contain metals and chemicals. The more the animal eats, the more metals and chemicals are absorbed. Additionally, the older an animal gets, the more contaminated the animal can become due to the accumulation of the substances over a longer period of time (Freedman 2007).

The most classic example that exists of bioaccumulation is that of DDT – Dichlorodiphenyltrichloroethane (what a mouth full!). DDT was a widely-used pesticide in the past and has roots during World War II. It was highly effective at eliminating mosquito populations and therefore preventing soldiers and civilians from contracting diseases that the mosquitoes carried. Eventually, this pesticide was used globally and we began to see detrimental effects on birds higher up in the food chain, such as birds of prey. As the DDT accumulated in the soil and water it began to bioaccumulate in the plants, insects, rodents, fish, and other animals lower down in the food chain. Birds of prey ate these organisms and the effect of bioaccumulation continued. DDT affected the reproduction of many birds of prey, caused egg shells to be soft and kill the offspring inside or caused eggs not to hatch altogether.

The population of bald eagles in North America crashed to less than 500 individuals in the 1960s (estimates of the bald eagle population less than 200 years earlier were as many as 100,000) (FWS 2015). Thus, the use of DDT was banned in North America and most of the rest of the world and the bald eagle population has seen a health rebound as a result. However, it is still used in South America and other parts of the developing world (Freedmand 2007).

Another example of bioaccumulation is with the common loon and methylmercury. This bird is a top predator in many lakes across Canada and can contain concentrations of methylmercury so high that it impedes their reproduction (Freedman 2007).

There are also some other factors that come into play when an animal is exposed to a poison. The toxicity of a poison may impact organisms differently due to the exposure or dose of the poison, which can further impact an organism due to the concentration of the poison and the amount of time the animal is exposed (Freedman 2007). The vulnerability or tolerance of the organism to a specific poison will also impact the toxicity of a poison (Freedman 2007). Bald eagles are particularly susceptible to lead poisoning and it only takes a small amount of lead to result in severe poisoning (Williams 2017).

There are several ways that you can help prevent poisoning of wildlife, and this blog wants to stress the importance of:

  • using non-lead ammunition for hunting and clay pigeon target practice.
  • hunters burying entrails or discarding them in a way that other wildlife won’t have access to them (Williams 2017).

Lead can also be found in some fishing lures, sinkers and jigs and is a major cause of death among common loons in eastern Canada and the US (Government of Canada 2013). This can be prevented by ensuring non-lead fishing lures are used.

Animals can show a variety of symptoms associated with poisoning, including but not limited to weakness, inability to walk, stand or fly (Williams 2017). If you think you have spotted a wild animal that has been poisoned, please call us at 403-946-2361.

If you would like to help future patients who may need special care due to poisoning, please support us ( or contact us to see how you can help.

Another great way to help the wildlife is to educate children; we offer education programs to do just this! Head on over to our Wildlife Education Programs page ( for more information.

Alberta Wetlands

Wetlands play a crucial role in Alberta’s wilderness by providing habitat for hundreds of species. These permanent or temporary wet areas cover approximately twenty percent of the province and are essential to the water cycle and aquifer replenishment. Wetlands are capable of absorbing large amounts of water making them invaluable to flood mitigation. Additionally, the wide variety of soils and microorganisms in wetlands help to filter water of harmful toxins making it safer for animals and humans to consume.

There are five classes of wetland which may be identified based on the source of water, presence of peat and the types of vegetation supported. These include marshes, ponds, swamps, fens and bogs which may be found across the prairies and forests of Alberta.

Each type of wetland is home to many species ranging from zooplankton through to moose. Grasses, shrubs, and trees also feature differently in each wetland class, but all help to provide food and shelter to fish, frogs, birds, rodents and larger mammals. This makes wetlands a great place for people to experience biodiversity and engage with nature because there are so many opportunities to witness animals in action! If you’re lucky, you may see a beaver or muskrat busy at work, a paddling of ducks, brightly coloured migratory birds or a deer stopping to drink. Looking closer, you will likely find the water is teaming with tadpoles, water striders or snails.

While wetlands have often been viewed as a nuisance in the past, their value is increasingly recognized and measures are being taken to protect these areas and the animals that call them home.

You can help by learning more about wetlands and by supporting AIWC’s rehabilitation of wetland wildlife. By dropping off donations from our Wish List, participating in our annual Month of May Baby Shower or signing up for our next Volunteer intake in September, you will be contributing to the recovery and release of wetland creatures.

Month of May Baby Shower


All the signs of spring are here… the weather is getting warmer, tulips and daffodils have surfaced and the sweet songs of robins fill the air. Unfortunately, though, otherwise healthy baby hares have begun to arrive at AIWC due to unnecessary intervention by well-meaning members of the public.

Baby hares are one example of the many reasons why busy season has arrived at AIWC, and why it is just the beginning in terms of the numbers of animals who will come into our care during the spring and summer months.  History shows that our clinic can expect to have 200-300 patients in care between May and September – most of them babies such as bunnies, nestlings and skunk kits.

Please remember to keep this excerpt from last week’s blog in mind “a baby hare that appears abandoned may not be in any trouble at all but could be waiting for his or her mom to come back to feed them. Mother hares often leave their babies for hours during the day to avoid attracting predators with her scent or movement. Moving these babies can cause far more problems than leaving them. Before intervening with a lone baby or in any situation, give AIWC a call for advice”.

Other than leaving baby hares where you find them, there are many ways to help support AIWC’s wildlife babies this spring. Members of the community can get involved by simply finding out more about our Annual Month of May Baby Shower:

  • Enter our Feeders for Feathers contest!
  • Donate to our baby shower!
  • Attend our onsite talk!
  • Donate items from our wish list!
  • Buy a copy of Scared Skunk!

Please visit our website at for more details on ways to help during the month of May!

Spring Fever: Six ways you can help support wildlife this season

Warmer months mean more wildlife! Whether it’s the birth of spring litters or creatures coming out of hibernation, spring is a busy time for Alberta’s wild world.

Here are six ways you can help conserve and protect.

1. Renovate your own outdoor space. A few quick changes can make your yard or property more welcoming to wildlife. Planting native flora, providing a water source and not using any plant or lawn chemicals will help. There are natural ways to control what grows in your space.

Reconsider cutting down trees that could be important nest or habitat sites for birds, squirrels,         raccoons, insects and other critters. If you must remove a tree, check it over carefully to make           sure you aren’t cutting down an active den or nest.

2. Think twice about trash. Consider that poor disposal of garbage causes problems for wildlife around the world. Here in Alberta we can do our part by disposing of garbage in bear-safe garbage sites when we are out in the wilderness, and never, ever littering.

Spring is a great time to revamp your environmental footprint. Consider composting as a great disposal option for weeds, lawn clippings and food waste.

You can go a step further by evaluating how much waste you’re producing! Can you cut back on items that come with excessive packaging or aren’t biodegradable? These are small decisions that can make a big difference for the environment and the wildlife that call it home.

3. STOP! CALL AIWC! (Or another local registered wildlife rehabilitator.) It’s a point that begs repeating. A baby hare that appears abandoned may not be in any trouble at all but could be waiting for his or her mom to come back to feed them. Mother hares often leave their babies for hours during the day to avoid attracting predators with scent or movement. Moving these babies can cause far more problems than leaving them. Before intervening with a lone baby or in any situation, give AIWC a call for advice.

4. Contrary to popular belief, it’s okay to pick up a baby bird. If you see a baby that seems too young to be out of their nest call AIWC for advice. If advised to do so, it’s ok to gently and safely place him or her back. Watch from a distance to see that the parents are feeding upon their return.

5. Get rid of anything that could be a trap! During spring and summer, many wild animals are seeking out dens and nest sites. Sometimes they end up in less than ideal locations like in an attic, chimney or under a deck. Scope out the areas ahead of time to prevent this. If wildlife has already moved in, don’t set traps! Wait and see if the family moves out on its own before considering humane eviction options. You can always call AIWC for advice.

6. Support AIWC. Volunteering or donating helps AIWC do its very best to keep Alberta wildlife safe in the spring. Your contributions make all the difference.

The Great Horned Owl

Did you know that the Great Horned Owl is one of the most common owls in North America?

The Great Horned Owl is aptly named due to the tufts of feathers on the top of the head that appear to be horns or ears. In fact, the ears of this owl (and some other owls) are located on the side of the head and are asymmetric, meaning one is higher up than the other (Lewis 2016; Cornell University 2015). Ear asymmetry typically occurs with nocturnal owls because they rely on their hearing for hunting (Lewis 2016).

Another physiological adaptation that allows owls to hunt better at night is their unique disc-shaped face which helps funnel sound to their ears (IPT 2017; Lewis 2016; Cornell University 2015; FRGZEV 2006).

Although this species relies heavily on their hearing for hunting at night, the eyes of this predator are also adapted to be able to see in low light conditions which further aids their hunting abilities (IPT 2017; Cornell University 2015; FRGZEV 2006). The large size of the owl’s eyes allow them to absorb more light over the larger surface area (IPT 2017). They also contain a tapetum lucidum, which is an adaptation in many animals species that allows them to see better at night time and is the structure that causes eyes of some animals to “glow” at night when light is shined on them (IPT 2017).

The Great Horned Owl is one of the earlier nesting species in southern Alberta and often breed as early as late January or February. This species lays 2 to 3 eggs and both parents take turns incubating the eggs. The incubation period is 30 to 35 days, which means we can see hatchlings in our area as early as late February or early March. If one of the hatchlings falls out of the nest early, the parents will still care for him or her by feeding them on the ground (Cornell University 2015; FRGZEV 2006).

If you happen to see a young owl that has fallen out of it’s nest, make sure you observe to see if there are any parents nearby. If you think the nestling has been abandoned, please call AIWC for advice (403-946-2361).

AIWC currently has a Great Horned Owl patient who fell victim to a methane flare. This owl will remain with AIWC until she completes a full feather molt and can once again fly. If you would like to help with the care of this owl, please visit our Adopt an Animal page (

Interesting Great Horned Owl facts:

  • The Long-eared owl is another species in Alberta who also has feather tufts that are often confused as horns or ears. Though, this species is much smaller than the Great Horned Owl.
  • They use nests that were built by a different species (such as hawks, crows, ravens, herons, and even squirrels) (Cornell University 2015).
  • The Great Horned Owl can weigh between .90 to just over 2.3 kilograms, with the female being larger than the male (Cornell University 2015; FRGZEV 2006).
  • The Great Horned Owl can catch prey much larger than themselves and often preys upon ospreys, falcons and other owls. However, they mostly eat small mammals and birds (Cornell University 2015).
  • The talons of this species are incredibly sharp, and hold on tightly to their prey. When clenched, the talons require a force of 13 kilograms to open them (Cornell University 2017).
  • The Great Horned Owl uses their ear tufts to display how they are feeling. They stand upright when curious and lie flat when disgruntled (FRGZEV 2006).
  • These owls are very stealthy. Their feathers offer camouflaging to the surrounding treed habitat and they are nearly silent when in flight (FRGZEV 2006).
  • Many people believe that owls can turn their heads all the way around, when in fact, they can turn them 270 degrees. They are able to do this because of extra vertebra in their neck (FRGZEV 2006).
  • Owl eyes don’t move in their sockets (Cornell University 2015).
  • The call of the Great Horned Owl is one of the more recognizable owl calls and is a series of deep, stuttering hoots – usually 4 or 5 in a row (Cornell University 2015). To hear their call, visit this site:
  • Great Horned Owls stay all year long in Alberta and also live in South America (Cornell University 2015; FRGZEV 2006).
  • (Cornell University 2015).
  • The Great Horned Owl is a predator of crows and crows often attack, mob, and chase owls in the day time (Cornell University 2015).

National Wildlife Week

In 2017 Canada celebrates 150 years of confederation and 70 years of recognizing National Wildlife Week. Each year National Wildlife Week falls around April 10th, the birthday of ‘Wild Goose Jack,’ who helped restore the Canada goose population after it was on the brink of extinction in the early 1900s.

While the Canada goose seems emblematic of the country and the year-long celebrations, did you know they are not Canada’s National bird? In fact, Canada does not currently recognize a national bird. In 2015 Canadian Geographic undertook a survey to recommend a species be recognized in honour of Canada’s sesquicentennial and narrowed the list to the following five candidates:

  1. Gray Jay / Whiskey Jack
  2. Common Loon
  3. Snowy Owl
  4. Canada Goose
  5. Black-Capped Chickadee

Although not yet official, Canadian Geographic is lobbying Parliament to have the Gray Jay recognized as the national bird as part of the #Canada150 celebrations in a similar proclamation to the one that identified National Wildlife Week.

The recommendation certainly ruffled a few feathers with some believing that the common loon—who appears on our one dollar coins—would be more iconic, while others felt the Canada goose was the obvious choice. In any case, it’s not worth getting in a flap over because they were all valid candidates along with many others.

The Whiskey Jack was put forward as the final choice for epitomizing Canadian spirit as a friendly, intelligent, and winter-hardy specimen.

National Wildlife Week and Canada’s 150th anniversary reminds us to commemorate all the creatures and contributions that support this country’s diverse ecosystems. Picking up a piece of litter, using window decals to prevent bird strikes, enjoying a spring day outdoors and snapping a photo of wild spaces all contribute to protecting natural habitats and remembering our enduring Canadian spirit.

You can further support our wild neighbours by contributing your time to AIWC or by donating to the care of animals. Your contributions help ensure that should a gray jay, loon, snowy owl, Canada goose, black-capped chickadee, beaver or any other Canadian wildlife find their way into AIWC’s care we can support their recovery and release them back into the northern wilderness.
