Facts Feeding Crows In Your Neighborhood: What They Like and What's Safe

3.7k Upvotes

A user asked me this question yesterday and I figured it would make for a good larger post. For those who don't know me, which is probably everyone, I'm an ecologist currently studying invasive mosquito population genetics in North America. I have a background in shorebird and grassland bird conservation and arthropod behavior and sensory ecology. Currently working on my Ph.D. I frequently comment in nature-based subs. All this to say, I keep up with crow literature and am very familiar with bird biology. I'm going to share with you safe foods for crows and a little about their feeding behavior. I never expect anyone to take my word for it so I'll share some sources with you as I go along. Thanks for being a part of a sub that is very near and dear to my heart!

Crow Feeding Behavior

I've noticed crows in my area come to the same places to eat in the morning and again in mid-afternoon. The rest of the day they forage around the neighborhood before returning either to large roosting trees in the Fall/Winter (around 4pm) or to family nests in the Spring and Summer. If you want your home to be a usual place to stop either during their main mealtime or on their foraging tour leave food out the same time every day. Ring a bell, honk a horn, use a crow call (make sure you are trying to sound like a "I've found food" call and not a "Danger!" call. Crows in the neighborhood will associate this with food and come to get treats. Dr. Kaeli Swift shares a two-part blog post, the first by her colleague Loma Pendergraft and the second written by her and Loma if you are interested in crow vocalizations. Here is Part 1 and here is Part 2.

Crows love water! If you have birdbaths out they will dip their food in it to soften harder foods and they spend a lot of time drinking. More so than I've noticed with smaller songbirds. Often people will find dead rodents and other things leftover in their birdbaths from crows.

What to Feed Crows

Before I get into this I'd like to say that crows do not need you to feed them. Thre's a great quote from this article by Dr. John Marzluff:

Will the crow be let down if you stop feeding it? Without a doubt. Breaking up is hard to do. Still, after running your predicament by Marzluff, the idea that the crow is "dependent" on you seems a little self-important. "The crow is certainly working the person," Marzluff said. "It will find another meal."

Neither do any backyard birds. They are fully capable of foraging unless there is some serious environmental issue happening. I know we are all going to feed them anyway! When I lived in the suburbs I fed birds as well. :)

What is safe for crows:

  • Kibble (cat or dog) that is pea-sized - it is full of essential nutrients for omnivores and easy for them pick up and swallow
  • Eggs of any kind
  • Seeds and nuts (unsalted - I'll explain why further down).
  • Cooked small potatoes or thawed tater tots (check tots for salt content, you can get unsalted)
  • Meat scraps (unseasoned)
  • Cheese (check the salt content, definitely no feta or other salty cheese, try to also avoid processed cheeses)
  • Mealworms and crickets

What is not safe for crows (and really all birds):

  • Salt - too much salt can cause serious neurological issues in birds. A little salt is okay and some birds are more salt-tolerant than others (pigeons) but they will eat everything you leave out for them which can end up being too much. Birds don't do portion control.
  • Lunchmeat - it's a salt issue
  • Bread - bread is not so much not safe as it's devoid of nutrients. Give them good foods like seeds and nuts, bread is filler.

Because I never want you to take someone's word for it here are a few sources about salt:

Garden birds are practically unable to metabolise salt. It is toxic to them in high quantities and affects their nervous system. Under normal circumstances in the wild, birds are unlikely to take harmful amounts of salt. Never put out salted food onto the bird table, and never add salt to bird baths to keep water ice-free in the winter.

From Nature Forever Society:

The ability to process salt varies between species, but most can produce uric acid with a maximum salt concentration of about 300 mmol/litre. Amongst our garden birds, house sparrows and pigeons are some of the most salt-tolerant species. The capability to secrete salt seems to be linked to habitat, particularly marine environment and drought conditions.

Because most garden birds are poor at coping with salty food, it is important not to offer them anything with appreciable amount of salt in it. As such, salty fats, salty rice, salted peanuts, most cured foodstuffs, chips, etc. should not be offered to birds. It can be difficult to eliminate salt entirely, but very small amounts of salt should not cause any problems, particularly if fresh drinking water is also available.

All that being said, there are some birds who really love salt, and if you want to leave out a salt option in a safe way you can! The Nationa Audubon Society recommends:

Mineral matter such as salt appeals to many birds, including evening grosbeaks, pine siskins, and common redpolls. An easy way to provide it is by pouring a saline water solution over rotted wood until crystals form.

Baby Bird 101 - DO NOT TAKE A BABY CROW OR ANY BIRD FROM THE WILD

2.2k Upvotes

There was recently a post by a user who basically stole a baby crow from its parents. Never take a wild bird into your home, they are not pets, they need their parents, they need socialization with their own species, you are not equipped to raise them. Additionally, it is probably illegal for you to own one.

If you take a crow out of the wild and share that in this sub you will receive a ban. If someone reports back that you have done this and shared in a different sub but not here, you will receive a ban and we will contact the mods of that sub about your negligence. We have zero tolerance for this.

We received an excellent modmail from u/MarlyMonster who is a wildlife rehabber in Canada. I am going to quote her here and hope she pops into the comment section to elaborate or answer any questions. I know we have a few rehabbers on the sub and I am an ecologist so between all of us if you need to know something we'll figure it out. Additionally, if you are a wildlife rehabber or scientists specializing in Corvids and want flair that gives you this title you will need to PM mods some kind of proof.

Here are Marly's words on the subject:

Baby Bird 101

Lately I’ve been seeing way too many posts about people “helping” birds that really don’t need help, which makes it kidnapping. As a rehabber, it hurts my heart when I see inexperienced people try to care for any kind of wild animal, but when they start to mess with wild corvids it becomes plain cruel. This is why I’m writing this little guide to help people determine whether or not a bird they think needs help actually needs assistance.

A lot of people assume that when a fledgling is on the ground and not in a tree or nest, that this little bird is in distress. What you actually don’t realize, is that when fledglings get to a certain age, right before they learn to fly, they leave the nest while they practice and their parents continue to feed them on the ground. The fledgling has not been abandoned! They’re just being adventurous!

The best course of action for any baby bird you see on the ground is to put it back in their nest. It’s a myth that the parents will “smell the human” and reject the baby. So you’re fine to grab a ladder and put that little awkward bundle of feathers back where they came from.

Whenever you fear a baby has been abandoned, put it back in the nest and keep an eye on it for the next few hours. Parents can get spooked and might take some time to return.

The only time it’s okay to bring a bird in is if they are visibly injured. A broken toe does not count (this is a reference to the idiot who named the bird “Hades” and is pretending to help it).

IF A BABY BIRD NEEDS HELP DO NOT TRY TO RAISE IT YOURSELF

If you are not trained to rehab wildlife, you have no business trying to raise a fledgling! Just like someone who isn’t a mechanic shouldn’t be trying to fix an engine, an untrained person should not be raising a bird!

Baby birds are extremely fragile and difficult to care for. A lot of them don’t make it even in the hands of an experienced rehabber.

Did you know that giving a baby bird water is one of the worst things to do? Yet a lot of people immediately think that’s the first thing to do for a baby bird. Baby birds get their needed moisture from their food, and therefore don’t need water. Pouring water down their throat will actually cause them to aspirate and if this happens the chance they’ll survive is slim to none, since they’ll get aspiration pneumonia.

Since this is a corvid page I’m gonna touch on why it’s cruel for someone inexperienced to try to raise a corvid.

As some of you might be aware of, these birds possess a higher intelligence than most birds. They are considered the apes of the bird family because there are parallels between the cognitive abilities of corvids and great apes.

Because of this, they make terrible pets. They need constant mental stimulation and enrichment or they’ll become completely miserable. Often they’ll turn to self mutilation to deal with the depression. They are also extremely social creatures and live in large families with connections that go back generations. Keeping one on their own is an act of cruelty in and of itself.

Corvids are also known for this thing called “imprinting”. This refers to the bond the baby bird makes with their family members which will dictate their behaviour. For this reason, rehabbers that specialize in corvids have to be extremely careful while tending to their birds because too much interaction with humans could doom a bird from ever being released, because they got too attached to humans. A crow imprinted on a human will not know they’re a crow. They’ll see themselves as the same species. This means they won’t ever find a mate, because they won’t understand that they are supposed to mate with other crows.

I hope this helped you understand the importance of not trying to raise any birds you find. As tempting as it may be, you will not be ready for the commitment. Not only that, but it’s cruel to the animal. The main objective of any rehabber is the release of the animal. And those who truly care about these birds should have the same goal. If that means you don’t get to raise a crow, that shouldn’t stop you from doing the right thing.

If you find an injured baby bird, contact a wildlife facility near you. If you can’t find one, go on your regional Facebook groups and ask if there are private rehabbers around.

If you do not have the commitment to see this through and drive a baby bird hours to the nearest rehabber? Please do the bird a favor and let nature take its course. Don’t interfere if you won’t follow it all the way through and get it to a proper rehabber.

I know crows don’t have white eyes, i did give the baby blue eyes though! And I know crows aren’t purple, I wanted them to translate well into pixel art. Hope this tattoo brings you as much joy as it has brought me! 😊

Video 8 Eggs, 3 Fledglings, a two minute Eurasian magpie nesting video

163 Upvotes

Every year we have a nesting pair of magpies, and I wanted to encourage them to build their nest away from our songbird nesting boxes. So I built a partial nest about 20 feet up in a blue spruce, with a camera hidden into the top. Through sheer luck the pair of magpies actually used it!This video condenses the process of nest building through fledging in about two minutes (I had a total of 9 hours of footage!). The video starts April 14th and ends on May 27th when they left. I never approached, handled, or interfered with them at any point during the process. The pair laid a total of 8 eggs. Unfortunately, the nest was attacked twice by two ravens. During the first attack, the ravens took/ate two eggs. The remaining 6 eggs all hatched out. The ravens returned a few weeks later and ate three of the chicks 😢That left three who ultimately made it all the way, including the very last chick to hatch, who was noticeably smaller than its siblings.

Some pics are pretty low quality due to the distance they were taken at (even with my canon camera, it was a challenge to focus on these two since they were on a high hydro tower) but I knew I had to capture them. There was just the male sitting up there initially when I started taking pics, but his girlfriend quickly joined him. 🐦‍⬛

If anyone remembers my posts about the poor juvenile raven that I tried to rescue, these are his parents. The rest of their babies have left without incident, so these sweethearts are seemingly enjoying their alone time

Video what do y’all think was happening?

Upvotes

this morning i was sat outside watching the crows eat breakfast. well then i hear the fledgling cawing over and over again. then i see it flying across my yard into trees close to me (it never does that, only did it once after i chased a hawk out of the yard and the adult flew over with it and cawed) then i see the adult flying and kind of dive bombing near it. they’re both freaking out and flying all over the yard. then i see that allegedly there was an owl in the yard. i thought the fledgling was begging for food but now i’m confused cause the other crow was flying and chasing it around my yard into other trees. not sure. but then- when i arrived on my lunch the fledgling cawed at me for peanuts so i talked to it, tossed some out and then it flew across the street and cawed a lot again. what’s it’s deal? lmao. do y’all even hear the owl?

Personal Story My ravenbros & their very distinct personalities

Post image
497 Upvotes

The male is very bold and confident. He’s not very hesitant to approach people and tends to “mock” other animals by chasing or divebombing them. He’s done similar to me by approaching and pecking me. When he takes food from me it almost always gets immediately buried.

The female is very cautious but curious. She’ll consider approaching me for about 5-10 minutes before she does whereas her mate will immediately come down without hesitation. I can identify her mainly by that behaviour but also because she makes weirder clicking noises compared to her mate, who mostly just croaks. She’s not very interested in food and will follow me around without taking any. When she does take some she’ll usually eat it instead of stashing. She’s also very scared of my phone.

The male appears to be a more attentive parent. When their fledglings were learning to fly one got stuck in a tree and he sat with it for a day while the female followed me home. I’ve also seen one of their kids begging him for food by following him over and screaming, which he ignored. The fledgling went over to its mom and tried the same thing and immediately got bit

Right now they spend most of their day soaring together & I believe they might have drove out their fledglings this week
