How to Make it a federal law not to shoot Crows
Your title and your post seem to contradict each other.
Who bothers to shoot crows anyway? I’ve never eaten crow, which suggests they are not tasty. And I have eaten some pretty weird things.
One crow stole my toilet paper when I was in day 3 of a ten day hike, but thowing a few stones got it to drop it, though I did need to climb a fairly large rock to retrieve it. I don’t blame the crow, it was a really remote area and the crow had probably never seen a roll of toilet paper before.
One of my familiy heirlooms is a silver spoon that some random crow managed to steal and then forget to pick up again when it landed for a drink in a birdbath my family had.
As it is unclear whether you support shooting crows and covids, or not… I’m just going to say, I am on the side of the crows.
This is probably not an ideal answer so early in this thread, so I will back out now until someone who knows the law can reply.
OP is just determined that shooting crows should not be optional.
I guess you could contact your representatives in congress and senate. Campaign for or (hopefully) against shooting corvids. Write letters to newspapers. I’m sure you have heard about all of that in school.
As with any law you would like to see you need to contact your representative and/or senator and have them sponsor a bill and then hope it gets passed.
AKIK, corvids (and crows are corvids) are not endangered. There are some specific ones, like The Hawaiian crow that are on the way out, but they are already protected.
There are many species that really need protection, and maybe your efforts would be better directed towards them.
As this thread appears to be asking for advice, i have moved it to IMHO, which is the usual forum for advice threads.
It already is a federal law to kill a crow, under the Migratory Bird Treaty Act.
The statute makes it unlawful without a waiver to pursue, hunt, take, capture, kill, or sell nearly 1,100 species of birds listed therein as migratory birds. The statute does not discriminate between live or dead birds and also grants full protection to any bird parts including feathers, eggs, and nests.
Most, if not all, members of the family Corvidae are covered under this law, including the American Crow and the Common Raven. The full list of protected species is available on the FWS website.
The real question, I suppose, is how often waivers are issued.
In Pennsylvania crow season is July 1-April 9, 2023, (Hunting permitted on Friday, Saturday and Sunday only). There is no limit to how many you can shoot.
I find the last two posts to be a very interesting juxtaposition. Something somewhere is confused.
Yeah, one of those two will be eating…well, you know.
“Say hello, tinky”.
No one mentioned murder yet?
Well, if a murder of crows is approaching you, it only makes sense to fire first since you’re outnumbered. 
I wonder if it’s illegal to feed ice cream to crows?
Looks like it’s crow season in California through Apr. 5. Daily bag limit is 24; however you can shoot as many raccoons as you like.
But to answer the original question, contact your Senator or Congressional Representative and ask them to pass legislation. You could also join an advocacy organization like the American Bird Conservancy.
Raccoons are also not kosher.
I don’t see how religious beliefs are relevant, since people who shoot raccoons clearly have no soul.
I want a pet crow.
That’s all.
