That is because irresponible pet owners allow it.Outdoor cats kill between 1.4 billion and 3.7 billion birds a year, study says
Anyone can legally shoot a dog that's chasing a deer.
According to an outdated 1940's law, I can't even walk within an eighth of a mile of an eagles nest without paying a $5000 fine if caught any closer.
I, and you, can go to prison, or be fined, if we pick up a bird feather if it's from a native, migratory bird. They are strictly protected by federal law. We cannot harm, handle, remove them, any parts, or their nests, etc, etc...
So why are cats and their owners who allow it given a pass to kill these protected birds? Oil companies have to pay fines for each individual bird killed. Why don't cat owners have to pay similar fines?
These deaths are inexcusable and should not be happening, period.
Some say "It's natural for a cat to kill a bird." It's also "natural" for a dog to chase a deer. So why the difference in standards? Why can't I kill a cat if it's stalking a bird?
One fact people overlook: cats are a non-native species. They do not occur here "naturally."
Other non-native species such as English House Sparrows and European Starlings are NOT protected by law. There is open season on them because they interfere with our native ecosystems by taking over nesting sites and sometimes killing less aggressive native birds. The government even used to PAY people to kill them.
They are trying to readicate non-native phragmites, Purple Loosestrife and Garlic Mustard in some areas because they are taking over where there should be cattails or other native plants.
In Yellowstone it is illegal to NOT kill a Lake Trout if you catch one. It is non-native.
In MI it is illegal to move firewood from one county to another because of the spread of the non-native Emerald Ash Borer. The insects are killing all of the ash trees here.
Again, cats are a non-native species, brought here by man from another continent, and as you correctly state, they kill billions of birds each year, many of those birds protected by law. Talk about a disruption of native ecosystems and severly declining native bird species! The felines also reproduce unchecked. Then bleeding-heart cat lovers take the unwanted cats to natural areas- where we still have a few remaining native birds- and release them, only so they can kill those birds that are still hanging on.
Then there are people, like Caveman here, who say "Puhleeze" when you suggest cats should NOT be roaming loose.
And he thinks >I< need to be educated!
