Laura Erickson and Archimedes
"Professor McGonagowl" and Archimedes, an Eastern Screech-Owl. This species is related to Ron's owl Pigwidgeon, a Eurasian Scops Owl. Pigwidgeon belongs to the genus Otus. Archimedes belongs to Megascops. Old bird books have them both belonging to Otus, but VERY old bird books have them the way they are now. One big difference is in their calls. You can hear an Eastern Screech-Owl here and a Eurasian Scops-Owl here. (Thanks, Bruce!)

(SPOILER discussion of Hedwig in Book 7--Harry Potter and the Deathly Hallows--is here.)

No spoilers beyond this point:

Now that five Harry Potter movies and all seven books have been released, people have become very familiar with owls. This website will give you facts about owls both in the real world and in J.K. Rowling's magical world. I live in the United States, but Harry Potter lives in England. Some owls live in both places, and some are found on only one side of the pond. I've studied owls for a long time and read all seven Harry Potter books and seen the movies, but I simply couldn't have written this and made it authoritative without a lot of help from a lot of people. If you have information I should add, corrections, or other comments, please email me.

In J.K. Rowling's wonderful universe, owls bridge the magical and muggle world, carrying messages, packages, and even Nimbus 2000s with ease as they make it clear to muggles that when a message needs to get through, it WILL get through. One Snowy Owl named Hedwig also provides warm companionship when a lonely wizard named Harry needs it.

If you have questions about owls, first look to see if you can find the answers here. If not, you can email Professor McGonagowl. As always, if you have questions, comments, or corrections, please let me know. To get more information, see:


Harry holding Hedwig from the movie
Harry and Hedwig. Notice that Hedwig is being played by a male. Harry is wearing a wool glove. But underneath the cloak, he is wearing leather arm protection.

Harry's owl Hedwig is a Snowy Owl. She's a female but, in the movie, the actors playing her are males. (One of the owls playing Hedwig was also the very first cast member to be chosen!!) You can tell that the owl playing Hedwig in the photo is really a male because his plumage is so white--female Snowy Owls have dark markings. Females are also bigger and heavier, and so would be a little harder for human actors to handle. Healthy males average about 4 pounds, females almost 4 1/2 pounds. They have powerful talons. You can't see in the photo that Daniel Radcliffe is wearing thick leather protection on his arm. Claws that can kill a large duck through thick feathers can be pretty hard on human arms, too, even when the owl is just trying to balance itself.

Seven different owls played the role of Hedwig. Their names are Gizmo, Kasper, Oops, Swoops, Oh Oh, Elmo and Bandit. I found out some interesting things on The Pet Place site about Harry Potter.

Real Snowy Owls live in the arctic tundra, in North America, Europe, and Asia. A few breed in the northern British Isles. Long ago, when the Arctic climate extended farther south than now, Snowy Owls lived much farther south. Cave art by Paleolithic people of Europe includes an etched outline of two Snowy Owls and their chicks on a cave wall in Ariege, France. This particular prehistoric drawing happens to make the Snowy Owl the first recognizeable bird species to be depicted in art anywhere in the world.

Snowy Owls are predators, and eat only animals, never plants. Their main prey species is the lemming, a fierce little rodent smaller than a chipmunk. Lemmings have enormous population fluctuations from one year to the next. When lemmings are abundant, Snowy Owls may eat hardly anything else. They usually swallow each lemming whole, head first, but if they're not too hungry, they sometimes bite off just the head, or even eat parts in small bits. But when lemming numbers are down, Snowy Owls eat a lot of other things. Depending on where they live, they may eat a lot of snowshoe hares, grebes and ducks (especially Horned Grebes), ptarmigans, ground squirrels, rats, partridge, and even fish. When a Snowy Owl's face gets gooped up with blood and guts, it sometimes cleans up by wiping its face in the snow. I have a couple of photos of wild Snowy Owls on my Snowy Owl Bird Photo Gallery.

Global warming is expected to hurt Snowy Owls over much of their range. Hedwig is lucky she lives in a magical world!


Errol arrives at the Weasleys with a message (from the movie)
Real Great Gray Owls aren't clumsy!

The Weasley family has a very clumsy owl named Errol. In the movies he's a Great Gray Owl. I don't think his species is actually mentioned in the books, but my friend Katty from Belgium found that he IS called a Great Gray Owl on J.K.Rowling's Web site. Measured from head to tail, the Great Gray Owl is the biggest owl in the world. But even though they're an inch or so longer than Snowy Owls and look just as big, they weigh much less than Snowy Owls--sometimes less than half! Also, their wingspan isn't as long as that of Snowy Owls, probably because their wings don't carry nearly as much weight. Great Gray Owls specialize on mice and voles, and have very thin toes compared to other huge owls.

In North America, wild Great Gray Owls live in Alaska and much of Canada down to northeastern Minnesota, and down into the mountainous areas of Washington, Oregon, California, Idaho, Montana, and Wyoming. In Europe and Asia, they are found in northern Scandinavia, Russia, Siberia, northern Mongolia, Northern Manchuria, Amurland, and Sakhalin. They make it to Great Britain only in the magical world of Harry Potter.

Real Great Gray Owls cannot carry very heavy items because they themselves are so light (usually less than 3 pounds!), and their feet are fairly weak. When I was taking care of injured birds, I once had to go rescue a Great Gray Owl that I then transferred to a raptor specialist. I had it for a little while, and was amazed at how innocuous its feet were. I normally took care of songbirds, so didn't have the heavy gloves normally worn when doing raptor work, but this owl's talons didn't hurt my bare hands at all. Normally over 90% of a Great Gray Owl's diet is one species--meadow voles. When they eat larger prey, such as rabbits and squirrels, they must sit on the animal for many hours, biting off small chunks of meat.

The Weasley's Great Gray Owl, Errol, is very clumsy. Real owls simply cannot crash the way Errol does in the movie. Not even the owl actor who plays Errol could really crash like that--like other birds, owls have hollow bones and are much too fragile to slam into tables and windows. In the movie, they filmed a real Great Gray Owl flying gracefully through the Errol scenes. Then they substituted a dummy owl for the crashes.

You can see many photos of wild Great Gray Owls at my Great Gray Owl Bird Photo Gallery.

This Great Gray Owl's talons are not hurting my hand. I helped this bird when I was a licensed wildlife rehabilitator.


Little Owl
The Little Owl of Eurasia is related to the Burrowing Owl of North America. But they are different species.

Pigwidgeon is so minute that some people have suggested to me that he might be a Little Owl, one very small owl found in England. This owl's scientific name is Athene noctua, and it is fairly common in much of its range, in southern and central Europe and Asia, and northern Africa. Little Owls aren't native to England, but were introduced there in the late 1800s. Little Owls are not found anywhere naturally in North America, but they are in the same genus, and closely related to, the Burrowing Owl. Like the Burrowing Owl, the Little Owl is found in open habitats, and is often active in the daytime as well as the night. The Little Owl often perches on posts and other look-outs. Like most tiny owls, the Little Owl eats many insects, which it can catch on the wing.

The Little Owl does have some interesting mythology of its own, being the sacred owl of the goddess Athene--that's how it got its scientific name. And it is shown on coins from ancient Athens.

But according to J.K. Rowling's own website, and supported by Mary Grandpre's lovely illustration in Chapter 22 of Harry Potter and the Prisoner of Azkaban, Pigwidgeon is a Eurasian (Common) Scops Owl. This owl, even tinier than a Little Owl and more closely related to the Screech Owls of America, has "ear tufts"--feathers that stick up on the head and look like ears. The owl illustration for this chapter clearly shows those feather tufts.

We hope the moviemakers use a scops owl when Pigwidgeon finally appears--he wasn't in the third or fourth movies at all, which has been a big disappointment to me and many others!

Ron seemed resentful to have such a tiny animal compared to Harry's Hedwig. But we bet he didn't have to work nearly as hard to clean up after Pigwidgeon as Harry did for Hedwig! Owl poop is smelly and messy. (Unless they're magical owls--we notice that Harry's black cloak never has a single white spot on it!)

Malfoy's Owl

Ealge Owl on Privet Drive sign
I wonder if this Eagle Owl on the Privet Drive sign is Malfoys?

Malfoy's owl is the largest, heaviest owl in Europe, an Eagle Owl. Eagle Owls are not found in the United States--they live in Europe and Asia. Eagle Owls are not native to Great Britain, but a few pairs have escaped captivity. Scientists hope they don't become established in the wild in England because like all introduced animals, they will almost assuredly disturb the balance of nature already there. But in their native range these magnificent birds are an important part of that balance. Eagle Owls have oranger eyes than Great Horned Owls, are slightly larger, and have heavy, vertical streaks on the front, rather than the finer, horizontal barring of the Great Horned Owl. Again, notice how it perches with the two normal front toes facing forward. (The "thumb" toe and the back toe face backward).

Percy's Screech Owl

Archimedes, my own education Screech-Owl

I didn't pay enough attention to another owl--Percy's! Fortunately, my friend Katty writes:

In the Harry Potter Lexicon about owls, they mentioned a screech owl. And in chapter 5 of Prisoner of Azkaban, you can find: "...Percy's screech owl, ..." (when Rowling described the Weasleys, Hermione and Harry leaving the Leaky Cauldron.)

Considering that my very own owl, Archimedes, is a screech owl, I really should have found this on my own!


Other Owls Appearing Here and There

Poster from first Harry Potter movie--a Great Horned Owl carrying letter
Poster for the very first Harry Potter movie. Great Horned Owls are not found naturally in England.

Throughout the Harry Potter movies, there are lots of owls here and there.

The owl shown in many of the posters, screensaver, and other promotional material for the movie, Harry Potter and the Sorcerer's Stone, is a Great Horned Owl. This owl lives in North, Central, and South America, but is not found in the wild in England or any other place on that side of the Atlantic Ocean. I don't know if this promotional material was used in England, but it makes a lot of sense for an American owl to deliver invitations to the movie to people in Canada and the U.S. Notice that the owl has two front claws on each foot facing forward. Owls have three front toes and one back toe on each foot. But one of the front claws is opposable, and rotates backward the way we use our thumb. So the way this owl is carrying the letter to Harry is, indeed, exactly the way a real owl would carry mail. Notice that owls prefer air mail.

Owls at Privet Drive
Real owls wouldn't be comfortable being so close to so many other owls. This scene was made using special filming techniques.

In real life, large species of owls sometimes eat smaller species. Real owls are extremely stressed by being near other owls. But filming the scene on the left did not stress the owls. Why? This scene was filmed over and over, with different owls each time, and then the films were digitally manipulated to make it appear that all the owls were there together at the same time.


Great Gray Owl in Diagon Alley
This Great Gray Owl in Diagon Alley helped make the atmosphere seem magical. From this angle, its eyes look very dark, but when the camera moved, you could see they are yellow.

Notes about the fourth movie: My friend Katty from Belgium, who is blind so notices a great many sounds I don't pay enough attention to, writes:

Yesterday, I saw the fourth film and was lucky to hear different owl sounds. In this movie, we entered the owlery (not a circular stone room as described in the books, but it seemed to be located outside the school). I don't know if you can see much of the owl species during this scene, but I heard the sounds of:

  • little owl
  • barn owl (maybe)
  • eagle owl
  • snowy owl
  • ???other species I didn't recognise. They seemed to be very active, But I don't know if it is evening or day in the film.

During the film, you can hear other owl species, but I don't know if you can see them. I heard:

  • little owl (on the graveyard
  • tawney owl
  • ??barn owl

The only species (and owl character) I didn't see or hear was Pigwidgeon.

Frequently Asked Questions

Hedwig carrying a Nimbus 2000 from movie
Is there REALLY a broom in that bag?

Could a real owl really carry a Nimbus 2000? I weighed one corn broom as 0.6 kilograms. Snowy Owl often kill snowshoe hares and can carry them to their nestlings. A snowshoe hare weighs over 1 kilogram, so the weight of a real broom wouldn't be a problem for a Snowy Owl. And a Snowy Owl's talons can easily grip a broom handle. So yes, a real Snowy Owl could really carry a Nimbus 2000. But the Snowy Owl in this scene simply flew through, and then the filmmakers digitally added the broom. This wasn't too hard to do. In the arctic tundra, where there are no trees for Snowy Owls to bonk into in flight, they often dangle their legs in flight. So in this scene, the real owl's legs are already in position to be carrying something.

Tiny owls can easily carry mice, so letters and birthday greetings would be quite easy for them to manage. But according to The Pet Place, "Although throughout the movie, it appears the owls carry messages and even the broom, they didn’t actually hold the objects. Instead, they were attached to the birds using an invisible harness. When they reached the right point, a trainer pulled a cord, which released the message or object." Also, notice that the broom that was delivered in the movie was really made out of paper.

Can real owls be happy in cages? The cage Harry often keeps Hedwig in is way too small for any real owl, and the tiny Victorian cage used in the movie would be illegal to keep an owl in in either the U.S. or Great Britain. Great Britain requires all bird cages to be big enough to allow the bird to stretch its wings fully without touching anything. To keep it in anything smaller requires a veterinary certificate. But the owl playing Hedwig is probably used to a fairly small cage when he goes places, the way dogs or cats get used to a small pet carrier or kennel, as long as they don't need to stay in it too long or too often.

Are real owls ever active in the daytime?
Owls that live in the Arctic, "the land of the midnight sun," obviously have to be able to hunt in bright conditions. Snowy Owls can hunt by day or night. And some other owls are very diurnal--the Northern Hawk-Owl and the more tropical Pygmy-Owls are active in the daytime. Many owls are crepuscular--most active at twilight. And some are active ONLY at night--the tiny Saw-whet Owl and Boreal Owl are good examples.

My Eastern Screech-Owl, Archimedes. I have to have state and federal licenses in order to keep him as an education owl. Screech owls are in the same genus as scops owls, like Pigwidgeon.

My own little owl, Archimedes, reminds me of a cat. He's active when he feels like it and sleeps when he feels like it, day or night. Screech Owls roost and nest in tree cavities or nest boxes, and are very vulnerable to jays, robins,and crows in the daytime, but they need some sunshine to produce Vitamin D, so they spend much of the day with their head poking out of the hole. If a cranky robin or jay spots one, the little owl just retreats back into the cavity.

Can people really have owls for pets? In the magical world of Harry Potter, a wizard or witch can own a real owl. In the real world, in England, people are allowed to keep owls provided the bird can be shown to be captive bred or found disabled and unable to be returned to the wild--in order to show owls for money or to breed them for sale, people in the U.K. need to have what is known as an "Article 10 certificate," which functions much as a licence for the bird.
In the U.S., keeping owls for pets is always against the law. In the U.S., owls and all other native birds are protected by the Migratory Bird Treaty Act, and cannot be possessed by anyone who doesn't have legal permits for research or education, or in the case of an injured owl, legal rehabilitation permits. I have permits to keep one Eastern Screech-Owl for education. I first needed to prove that I have a good reason to use an owl for educational programs, and that I could provide healthy, safe, and comfortable housing and good food, in order to apply for a permit from the Minnesota Department of Natural Resources. I needed a permit from my state in order to apply for a federal permit from the U.S. Fish and Wildlife Service. After I had both permits, I was allowed to keep one screech owl, but wasn't allowed to take it from the wild. I had to find a rehabilitation center that had an owl that had recovered but couldn't be released into the wild.

How can I see a real, live owl in the wild?
Owls are secretive in the daytime, because they are often attacked by crows, ravens, jays, robins, and other birds. If you're walking in the woods or in a park and hear what sounds like exceptionally angry chickadees, or a large number of extremely loud crows, check it out! They may be mobbing an owl. At nighttime you can listen for owls, especially in late winter and spring. To hear how some owls sound, you can look at Journey North's owl dictionary.

Find out if your town or city has an Audubon society or other bird club. Most bird clubs have field trips, and will have experts along to help you see all the birds. And they might have some special trips just to find owls!

How can I help owls?
There are several things we can do to help owls.

  • Buy your Harry Potter books from the Canadian publisher, Raincoast. This company prints all the Harry Potter books on 100% post-consumer recycled paper. This helps many kinds of owls because so much owl habitat is cut down to make paper.
  • Don't waste paper. Recycle paper when you're done with it, and buy recycled paper. How does this help owls? On average, Americans consume 738 pounds of paper per person per year. And much of this paper is wasted--over 40% of the trash Americans throw away is paper. That adds up to a lot of trees! And when forests are cut to make paper, it hurts the birds that require older forest growth. One way you can save paper is to stop getting junk mail. Four million TONS of junk mail is sent through the U.S. Postal Service, and half is never even opened. That is an enormous waste of forests. This website has information about simple things you can do to get less junk mail.
  • Keep your cat indoors. House cats kill millions of birds every year. Rarely, a Great Horned Owls kills a cat, but since even the heaviest owl weighs only 4 - 5 pounds, owls are at a serious disadvantage when in a fight with a cat. Even if an owl survives an attack, a cat bite or scratch can introduce bacteria leading to lethal infections. Bird lungs are on the back, making them especially vulnerable to puncture wounds. Also, cats kill a lot of mice. Except in very urban areas where rats and mice are a problem for humans, house cats destroy a lot of valuable owl food, making it harder for owls, especially smaller species, to survive. To learn more about the importance of keeping your cat indoors, see the American Bird Conservancy's Cats Indoors campaign page.
  • Don't let your dog chase birds. When an owl kills a large prey animal, it sometimes spends several minutes on the ground eating. During this time, it can easily be killed or badly injured by a dog. We know of at least one screech owl that was grabbed by a dog, and the tiny owl's wing was broken. If people had not noticed, it would have died, but now it's in a rehab facility.
  • Leave dead trees standing. If they absolutely must be cut, then to do it in the late fall/early winter to ensure no babies are in the nest.
  • Put up a Wood Duck/Screech Owl box or a Barred Owl nest platform. It's not a good idea to build both kinds close to one another, though!
  • Support an owl rehabilitation center near you. In Minnesota, The Raptor Center does a great job of caring for injured and orphaned raptors. This page lists many other rehabilitation facilities. If you know of a place that is not listed, please email me.
  • Join an organization that works to protect owls. My favorite American organization that does research and education to help all birds is the American Bird Conservancy. The Rainforest Alliance protects tropical birds, including the many owls that live there. The Royal Society for the Protection of Birds protects birds of the world with special emphasis on the United Kingdom.
  • Don't even think about having an owl for a pet. Owls are protected by law, so it's illegal to keep them in captivity in the U.S. without a license. But at least as important, owls are wild, natural birds requiring a wild, natural life. In cages they simply cannot do all the things their bodies were designed for and their spirits require. Also, owls are not at all easy to care for: they need to eat whole rodents or other whole animals, which must be fresh, and their droppings are messy and smelly, requiring frequent clean-up. If you yearn to handle real, live owls, volunteer to help at a nature center or rehabilitation center.
  • If you're buying owl stuff, buy them from Owl Stuff. Proceeds from t he Owl Stuff website go to conservation organizations.
