About me

I’m Kaeli Swift, a PhD candidate at the School of Environmental and Forest Sciences at the University of Washington.  I have been passionate about animal behavior all my life, but what started as an early love affair with wolves has turned into a fierce ardor for corvids.  Specifically, my area of research is the thanatology of crows.

thanaCrows, like a number of other animals that includes non-human primates, elephants, dolphins and other corvids, appear to respond strongly once they discover a dead member of their own species.  Among these animals the responses can include: tactile investigation, communal gathering, vocalizing, sexual behaviors, or aggression.  For people who live or work closely with animals it’s tempting to anthropomorphize these behaviors based on our opinions of how smart or emotional the animals we care about are.  But as a scientist my job is to separate my personal feelings about animals, and use research techniques that allow me to objectively ask questions about animal behavior.  By conducting field experiments and employing brain scanning techniques developed by our team, I hope to gain insight into the purpose of crow funerals.  Perhaps they play a utilitarian purpose of learning about danger or social opportunities, or perhaps they are akin to the grieving process we experience as humans.  The brain scanning technique we use allows us to peer into the brain of a living, thinking crow, without ever having to euthanize the animal.

Studies that provide bridges from humans to other animals are critical to fostering a culture that respects and protects the natural world, and this is one of the reasons I most enjoy working with crows.   No matter their feelings for them, nearly everyone has a story about crows, even those people who otherwise feel quite separated from nature.  The fact that they are conspicuous and thrive in all kinds of human dominated environments, means that crows are a uniquely accessible animal, and offer a wealth of opportunities to connect people of all interests and backgrounds to science.  It’s my hope that our research will provide a more compassionate lens with which to understand crows, and contribute to a growing movement of corvid enthusiasts.  Feel free to ask questions or share your own stories in the comment section!

    Hi Kaeli,

    In regards to facial recognition, at what distance can a crow identify a known face ?

    Shaun Chandler

    • ooooo that’s a great question. That’s never been explicitly tested but in my experience they can see a familiar face from far away, up to 75m. Their eyesight is excellent!

      Hi Kaeli, I think you are now post your crow funeral research but I wanted to share with you my experience as a, let’s say, a crow funeral director.
      I was on my way to an appointment and parked my car on a residential side street, off the main arterial. Getting out, I heard a distressing caw. A single crow on the pole wires above me, looking down, at me, and the road. There, in the middle of the street, a completely flattened crow. Poor thing, looked like it recently got struck. I felt bad and I didn’t want to leave him there. I didn’t exactly want to pick up a freshly squished crow either. I looked up to the sidewalk to see if there was something to use. Up on the grass, near a tree, was a paper plate. A clean paper plate. So, sliding the dead crow by the wing tip, and praying he would move in one piece, I slide him up on the paper plate. Then I walked back over to the tree and placed him at the bottom on a grassy mound. There was a lavender bush nearby and I grabbed a handful of flower spikes, sprinkled them on the crow, said a little prayer, and ran off to my appointment. When I came back to my car there were 10-12 crows silently sitting up on the telephone wires above the tree where I had placed the crow. A few looked down at me, and I swear, bowed and bobbed a bit when they saw me. What a touching moment. Thanks for reading. /Users/joeyshyloski/Desktop/IMG_2048.jpg

    I just started feeding my crows within 3 weeks to a month. They come now when I give a certain whistle. But one cooed at me. So now I’m looking up that meaning.
    I’m just south of Seattle! Go cougs.

    • Hi Heidie, you’ll discover lots of cool new calls you can only hear if it’s quiet and the birds are close to you. We know VERY little about crow calls but I encourage you to explore anyway. Beware of phony “crow experts” trying to sell you books or courses aimed at teaching you to decode crows. Good luck!

    What a wonderful research topic! I love corvids and have now signed up to your blog as well as following your twitter account. All the best with your work!

    Great blog!
    I have been trying to observe and learn about crow behavior at the large outdoor facility I work at in South coastal B.C. ..crows seem to recognize me when I arrive, from often at least 75- 100m as they swoop over looking for a scrap of food I regularly offer. Sunglasses and a change of hats seems to offer a disguise they don’t always see thru.
    I have one charming favorite in particular that coos and clicks and bob’s his head.. as opposed to the full body/full throated CAW! , they often favor.

    Hi, Kaeli–Great website! Question about crow behavior: A mourning dove was foraging on the ground and a crow (either Fish or American–we have both) flew from a low branch and swooped down, feet extended in hawk-like fashion, and appeared to try and “take” the dove.  He was unsuccessful, but it was weird. He did not dive at or peck at the dove like he would have if he was chasing it off. Any insights on this behavior?

  6. Hi, I am wondering if you have any insight into placing orphaned babies with a surrogate raven parent? I work at Hope For Wildlife ( wildlife rehabilitation centre in Seaforth, Nova Scotia, Canada), and we just got four young ravens in, but we also have a permanent resident adult raven on site. If you are able to give me any information it would be greatly appreciated!

    • Hi Amy, rehab isn’t my are of expertise but I’ll leave the question up for others to address

    • Alexandra Y.

      Hi Amy,

      I wish I had not seen this comment so late, but if you still are in need of help I may be able to put you in touch with someone who would potentially have some insights, but judging by the date of this comment it may be too late.

      Let me know if it would still be useful. If not, I would be very interested to hear what you did!

    Hello Kaeli
    I came across your blog via Twitter this morning and I am really interested to hear of your field of study. Some years ago I was in Calcutta staying in the heart of the city where the population of house crows is huge – a never ending source of fascinating observation. I saw for myself, only once, a remarkable piece of “thanatology”: dozens of crows in an evenly spaced crowd gathering round a piece of one of their kind – the wing of a crow – all that was left after a road accident perhaps – and they spent as long as I had time to watch touching, moving, the wing, gathering around it, silently engaged in a ritual process. I have always thought this a fascinating field of study and I am not sure if you ever would get to India in your work but I thought I would just put the idea out there, there is a treasure trove of material among the large numbers of house crows and the hazards of urban life.
    Warm regards, Kate

    • I think it would be wonderful to do some of this research in India particularly because crows have a crucial roll in the human death rituals common across India (as is my non-Indian understanding anyway). There would wonderful opportunities to make some some really interesting interdisciplinary connections there.

  8. Wendell Hocking

    Hi, Kaeli-I’ve been following your Twitter feed for a while and enjoy everything corvid. For the past 5 years a crow has been visiting my feeder. I first noticed it because of its wonky r. wing. The feathers look beaten up and the wing drags. It appears to flick the wing to keep it off the ground. Now it’s hanging with a second crow with the same issue. (I’d like to think they’re related!) What could cause their dragging wings?

  9. Greg

    Hi Keali,
    I just read the NPR article about crow funerals; fascinating stuff. Anyway it reminded me of this video I recently saw on FB of wild turkeys circling a dead cat, so I just searched and found it on YouTube. I don’t know where it was filmed. Perhaps you’ve seen it already. Just wondering what this behavior might mean.


    • Turkeys are found of playing “follow the leader.” There’s lots of videos of them circling trees for instance. If I had to guess I’d say one waddled over to take an interested look, another followed and so on and so forth. Rather that jostling for a best position they just started moving and voila! A macabre circular inspection team has formed. Just my guess.

  10. Hi Kaeli – Interesting story for you. I went into my yard a couple of weeks back because my local crows were cawing and there were more of them than I normally see together at this time of the year. Sadly, I found a dead juvenile crow under my neighbor’s eucalyptus tree. My neighbor’s dog seemed to be curious about it and was approaching it repeatedly, but each time she would approach the dead crow, the adult crows dropped sticks on her to scare her away. This was the first time I had seen the crows that upset and the only time I saw them dropping sticks on another animal.

    • I’ve seen them pull sticks when they’re agitated and John Marzluff has a story about a raven swinging a stick around at a predatory barred owl. It would be huge to learn if your crows were doing this intentionally or just kind of by accident.

      • Ok – so, I’ve definitely seen them rip off bits of branches and leaves when they’re agitated, but this just made me recall something one of my friends told me last week. He said that a few mornings in a row, one of the mated pair on his block would pick up large sticks when he took his dogs out for a walk and perch above them from roof to roof. He said it looked like the crow was dangling it above them and getting ready to drop it on them.

  11. K Schlesinger

    Have a story you might find interesting. We rented a house for 3 weeks at the beach. The house next to ours was a private home. On their back screened porch they were rehabbing a injured crow. Each day for those three weeks several crows would come to visit and “talk”. We found it fascinating that the crow had such dedicated friends.

    • Sounds like it had imprinted on them. Imprinting stories are sort of a sore spot for me because while I think the interaction unquestionable life changing and may of the story that come from it do a lot of good in terms of broader cultural opinions about crows…more often than not these birds are killed more quickly or are deprived of their basic biological needs or behaviors in some way. So it’s tricky…

  12. Carol Dean

    Hi, I totally love crows and would love to get more into helping with research about them. Does anyone in your department ever need volunteers for projects?

    We have a crow that landed in our yard last year when he left the nest early and couldn’t fly. We provided water for him but left him alone, and I guess he feels safe with us. Now he comes back regularly to hang out. His mom and dad are nesting across the street, and I hope we’ll get to see him help raise the new siblings. We have imaginatively named him ‘baby crow’!

    • Hi Carol, I’m afraid at this time most of our crows study’s are either coming to a close or working on a much smaller scale. That’s a wonderful story about your crow friend though. I am always happy to hear when people leave babies to their parents and develop their relationship another way.

  13. Cheryl Marelich

    Hi Ms. Swift,
    The link to this blog talked about your research of crow funerals. I have experienced one once when a crow was apparently hit by a car in front of my house early one morning. What woke me was the cacophony of caws happening in the trees overlooking the dead crow. It was incredibly loud as there seemed to be at least one hundred crows. As the dead crow lay in the street, a pickup truck came by. The driver opened his door, flung the crow into the cab of his truck and drove off.
    All the crows in the trees immediately stopped cawing and then flew off all at once. It was mesmerizing!

  14. Michael E. Bierman

    Wonderful. Great work. Thank you!

  15. Sarah

    Hello! Found your site whilst trying to see if what I saw today was a known behaviour of crows. A crow flew past me with a small nest in its beak, which I assume it had just lifted from the bush it flew from. It then landed on the ground nearby and devoured the eggs. I was a little shocked.. I know they do eat eggs but it lifted the entire nest out! I think it was a chaffinch nest, only judging by pics online. Curious to know if that’s been seen before. It might explain another side to fallen nests.


    • If it’s small enough and they’re in a hurry it might make sense that i’d be easier just to make off with the whole nest rather than take the time to pluck out each egg. This is pretty common across lots of nest predators.

  16. Josh Zelecki

    Just seen your piece on Bill Nye Saves The World. I have always been intrigued with nature and animal behavior. I couldn’t help but fond somewhere to contact you in regards to crows gathering to mourn. Was just curious if you’ve considered a instinct to congregate and try to identify the predator responsible after sighting a dead bird? Really wish I could perform the same test and introduce a predator decoy after they gather. Would be so exciting to watch.

  17. Michele Douglas

    Hello there~
    I have developed a relationship with the crows in my neighborhood over the last 3-4 years. We had two rather harsh (for Oregon) and all the birds were needing water and I also left out high energy food for them. Of course the crows came. Soon they would follow my car anytime I in the area on my way home and call to eachother when I got home. Two would come very close to me after I left treats and let me stand close. In bad weather I once counted 40 or so crows in my yard and lines. Such a delight! The parents started to bring their young to my house and it was such fun to watch them grow and grow. But tragedy struck this year – one morning I heard very agitated cawing. I went out several times to make sure all was well. The crow was perched up in a tree they don’t normally sit in and “yelling” at me. Finally the fourth time I went out, I found another crow, dead in the bushes, under some other trees, near the first. I was so upset. The moment I found the dead bird, the other instantly stopped cawing and stayed still, watching me. After that, it flew away. For a period of a week and a half I had zero crow activity at my house which bothered me. Now I have one back who has taken over both of my birdbaths. It comes to eat when we do in the back. I know crows learn and warn others when a place/person is dangerous – is it possible that the rest of the crows are staying away because of the one death?

  18. Alyssa E

    Hey Kaeli,

    I’m so intrigued with animal behavior and love your research. Question – which I think I know the answer to – have you ever witnessed cannibalism after a crow funeral? What about other rituals, or do they tend to fly a way?

    • Hi Alyssa. Cannibalism is extremely rare in corvids. I’ve never seen it in my studies but of course I couldn’t because we use taxidermy prepared specimens. As for other behaviors…I have a new paper coming out in July. You’ll need to wait for that 😉

  19. Stupidguy

    Two days ago in a forests i found a crow cornered by cat and thought its injured i was know nothing about crows , and after read this website i suspect i May mistakenly take a fledging , anyway since it cant stay on its both legs and looking like balance problem and i dont know if it get touched by that cat , i have questions like how can I be sure if its injured or no , do i must bring back this crow immediately or after it learn to fly? İ feel so bad and thinking how terrible thing i did , please help me asap i beg you

  20. Tuhin Chakraborty

    Cool video. Do you know whether these crows have high CRH in their blood? I am curious whether sight of conspecific death make them anxious. So seeing the video, I guess these birds form an associative memory.

  21. Johan

    Well, you just made it on Belgian television with the corvidresearch. And with mask… 😉

  22. We have a crow that says “Hello” clearly. It’s been heard by a few people. It doesn’t hang around the homes. I rarely even see crows here. How would it have learned that?

    • It’s an escaped pet. There was a crow in Montana that knew how to say “here boy, come boy” and spent a week tormenting the neighborhood dogs before it finally disappeared!

  23. Joseph Vinegar

    Good day
    There’s this fairly famous 4chan thread called The Great Crow War. It’s a greentext story about a guy who befriends one group of crows, and becomes an enemy to another, resulting in a crow battle. Is there anything you could teach us particularly from this story? Things like crow morality, psyche, and group-forming? http://knowyourmeme.com/photos/738480-4chan

    • Not really, as I don’t find the story credible. While it draws on aspects of crow biology (things like pre-roost gatherings and facial recognition) that are very much true, it also hinges on a couple of assumptions that are not true (things like site fidelity during pre-roost gatherings, and how/when physical altercations between crows take place, etc.). Hate to be a bummer, but this is just a great work of crow fiction. Still an interesting read though!

  25. Shaun mcdonald

    Hello I have found a injured fledgling crow he dosent seem to be a baby and is not eating by him self or won’t be hand fed he’s verry friendly I was just wondering is there any thing I can do to maybe get him eating he also dosent know how to fly

  26. Hidden San Diego

    Hello! I am hoping you can answer my question. A few weeks ago I took in a fledgling crow with a cold and infected eye. After seeing an aviary vet I was able to get it proper antibiotics and helped heal it. It now lives outside but visits me several times a day for feeding and love. Although it is learning to feed itself it still relies on me to help. Beyond this, I believe it’s family is bullying it! Therefore it hangs out alone. My question is, I am moving in a few weeks and desperately want to take it with me to live in my new backyard. Do you think this is a good idea? Do you think the crows in that area will try to hurt it? I am afraid it will not stand a chance if I keep it at my old house as it needs to be fed still. Help! Thank you so much! ❤

  27. James Monahan

    Hello Kaeli. I very much enjoyed your talk yesterday at the Hearthstone. My experience with feeding the crows shows me that they much prefer the “Iams minichunks with real chicken” to the in-shell peanuts that they often just pick up and drop back onto my deck or fly off with, or seemingly swallow it whole. The most prominent behavior I notice is that they look around so much as they are eating as if there are close by predators. God bless you in you interesting work. Jim

  28. Lauranda

    I’ve enjoyed your blog immensely and have learned a lot from it in the past 3 years! Thank you for what you do! I love crows and strive to watch them whenever possible. That being said I witnessed something I have yet to see or read about in crow behavior.
    I live in NE Portland, OR. I live very close to the Juvenile Detention Center off of I84 and NE Halsey St. There is an area that is semi wooded and not visited or walked thru by humans. This area was the site where I witnessed at least 60 crows gathered together and making noise I had never heard. At first I thought this was a funeral, as I had seen one before. But in this case what I witnessed was a crowd of 20 to 30 crows fly in a huge group and would make rounds out from the trees and back out. Then I saw three different pairs fall together to almost the ground. This went on for at least 30 mins that I know of and watched it before catching a very late bus. This happened in February of this year. And I have never seen it or have seen this behavior outside of falcons or eagles. Was what I saw a mating ritual of some kind? Thanks again and looking forward to your reply!

    • When you saw they were falling to the ground, could you clearly see the ground? Is it possible there was a red-tailed hawk on the ground with prey? Alternatively, do you recall if it was windy? They might have been playing in the drafts.

  29. Bev Kosty

    Our “Gambino” family of crows (our nick name for them because of how they own our property) are pure joy!!
    When they see us on the deck they will
    Watch us for up to a half an hour. They
    Will come close when I put healthy
    Treats and make clucking sound and
    A young crow that was a little ways from his family looked at me and fluffed his feathers and called
    To me. I have put out fresh watermelon
    And they love this treat. They are the best watch dogs. We don’t have other crows crowding our property like we used to and when food is put out they are so quiet so the other crows don’t know what is going on. We have a kestrel that comes around to catch little birds at our feeders and the crows chase it away and warn everyone it’s near! We feed them: eggs, walnuts, steak, chicken, cherries, dates, cheese but we are careful to not over load them so the eat there much needed natural diet. We
    Have two clear basins that they love to take a bath in. The dominant crow “Spats” has come close to the kitchen window to look at me doing dishes – it is a purposeful check to see me and check me out. They follow my husband when he cuts the grass to pick up the hidden bugs. We are blessed by their friendship.

    • The bond people humans and crows in an incredible thing. Don’t get me wrong, all wildlife is wonderful (yes even the kestrels, which need to eat too!) but I just adore crows. Nothing like them.

    • Venita Gallaway

      I am new to this group and have wanted to comment on the comments for a very long time. I grew up in FL, but moved to Maine 5 years ago. I have had 4-6 crows come and check out my three song bird feeders and eat from what falls on the ground. When I hear them outside, I’ll go out and put an assortment of items I know they love. Still, they are very shy and fly away. Other times they call (to me?) and I’ll go out and put the food stuffs then go back inside and wait. They can see 6’ inside, and if I move around too much they will fly away. There is one very large crow, or maybe a small raven b/c he comes alone and his tail is pointed. He quietly watches and sometimes will come down to eat. He will fly away when the crows come in. I know that the crows live behind my house b/c there is a lot of water and trees to hide in. Still, after 5 years, it’s just frustrating for them not to see that I feed all the animals here, except when the foxes come, they caw and I’ll go out and run the foxes off. Maybe that’s why they fly off too? I will call to them if I see one, and maybe they will come in to feed if I stay out of sight. What can I do?

      I really love these beautiful birds and will do whatever I can to gain a little trust with them.

        I’m sure Kaeli will have a better answer, but I’ll tell you what I did, and maybe it will help. I’ve had great success twice with this method: I started putting out what I knew they’d love (roast chicken seems to be a big favorite and my special “crow bars”). I did it at the same time every day (I waited until I saw them around). It didn’t take them long to know that I was running a 5 star crow take-out. Then, I sat inside by the glass door or window so that they could see me but still feel safe. Finally, I was able to leave the door open with just the screen between us and they’d land a few feet away. The bravest ones, Bran and Edgar (the mates of Raven and Posey, respectively) would tap on my window and/or follow me around the deck when they saw me. They’re fabulous friends, and I miss mine so much. I had to move, and now I have chickadees, but sadly, no crow friends. I think it’s just too busy here… but I’m going to find a new place this fall, and I’m going to make sure it has CROWS nearby.

        Good luck with your new friends!

      • Hi Venita, sorry I missed this comment. Not sure how that happened, but luckily Elle brought it back to my attention! Sounds like that one bird is definitely a raven. As far as why your birds are so shy it’s probably a combo of not being used to people feeding them and potentially being locally persecuted. Elle’s advice is really spot on. Be consistent, give them space, and expect slow improvements. Or there’s just a chance these birds are too shy and there’s not much you can do about that but continue to appreciate them from afar :/
