There is no secret to making friends with crows. Like many things in life, it requires time, patience, and disposable income.
Step 1: Find Crows.
Crows tend to hang out where humans leave trash, so they’re everywhere.
Step 2: Leave food out for the crows to eat.
Crows are carrion-eaters, they’ll eat almost anything.
They like raw peanuts (in the shell, unsalted, not roasted either), they like suet, and they like wet and dry pet food. They love popcorn, too.
Don’t sit and watch them eat, it’s rude. That, and they’ll think you’re a predator.
You’re often better off dropping food and walking slowly away, until you earn their trust. Give it time.
Step 3: Repeat and wait.
Eventually, the crows begin to recognize you. Eventually, the crows won’t be as wary of you as they are other people. Still, even when the crows know you, they don’t come that close.
At the end of the day, the crows are wild animals. They have good reason to be wary of humans.
I’ve been feeding my local crows for over a year. They still keep their distance, but they will chase me around the park.
Summary

Step 1: Find crows.
Step 2: Leave food for them to eat, but don’t sit and watch them.
Step 3: Wait.
Pet food stores are your best bet for unsalted peanuts, suet too.
Once they begin to trust you, well, be less afraid of you, they’ll start to eat food when you’re nearby. From there, it’s just a slow and steady progression until the crows start following you home.
There isn’t much more to it—you just do kind things, and wait to earn their trust.
