Well here in the UK you would be surprised what is threatened. And this is global!
Starlings have RED status and are a protected species.
The humble Sparrow is also RED status and under threat.
Serious pest control is one thig, but nothing and I mean NO BIRDS except game, can be taken EXCEPT under general licence, even then it is restricted to vermin
Starlings are no longer on the list of UK pest species
Sparrows are no longer on the list of UK pest species
CROWS & ROOKS
Anything else are song birds and protected, Black Birds are also protected in the UK and considered a garden bird.
Personally, shooting anything other than game or vermin is a bit sick. We should think before pulling the trigger, we share this planet with other living things and just killing it for a bit of fun under the pretence of, 'they shat in my dogs bowl' is a bit lame! If your not careful the anti's will be all over you, just like here in the UK and it will be shooters who are the endangered species. Have a little respect and don't give shooting a bad name!
