It’s a lot of fun to feel like you have wild friends, and feeding birds is a great way to connect with nature. I’ve been asked many times how to make friends with local corvids, crows in particular. While this post is mostly aimed at American crows in North America, it’s applicable to most corvids. However, please be aware of local laws regarding feeding birds.
The best way to get on a crow’s good side is through their stomach. Unsalted peanuts in-shell work wonders (i.e. crow crack). The best thing you can do is put out peanuts consistently and don’t look directly at the birds when you do so (at least initially). Be conspicuous about you being the one to drop the food, but do not throw the food toward the crows or look at them initially, but do make sure they are in the area. Then, go back inside. It may take them no time at all to come to your food, or it may take them a while before they trust it. Crows are very neophobic and suspicious, and even if it’s a food they love, they will be careful simply because it came from a human. (I suspect if you live in an area with high traffic or restaurants nearby, they will take less time to come to your offering than if you live in a quiet, low-traffic suburban area.)
Over time they will get more comfortable with you and start to expect food from you, and from there, you can build a bond of trust. The big thing is not startling them once you put the food out. Eventually you can look at them, be outside when they come down, and in some cases, they might just perch nearby while you are hanging out in your yard. Other foods that are great for them are things like dog and cat food (high protein) and even cooked eggs and egg shells (especially during the spring). Cheeze puffs and cheezits also tend to be a favorite, though I can’t say much about their health value.
A word of caution: You may alter social dynamics. Neighbor crows may get wind of what you are doing and challenge the family that normally occupies your yard. If you provide too much food, your home may become a communal site, and the number of crows can get out of control. Use your best judgement and I recommend just feeding a particular amount on a schedule and maybe supplementing them as you see them, to build your relationship. Another thing to keep in mind is the dynamics with your neighbors. Most people are fine with occasional feedings, but sometimes neighbors get upset if too many crows hang around for too long. Be mindful of your neighbors, and better yet, as you build your relationship with the crows think about educating your neighbors and getting them interested in your new buddies too.
Observing crow families and getting to know their individual personalities is highly rewarding. Having them trust you enough to use your yard as a safe haven for foraging and eventually, even bringing their young kids around is especially rewarding. Enjoy and I hope this helps you make some new, wild friends!
