House Sparrow Male

I have a love-hate relationship with this species.

They are not native here and wreak havoc on the native bird species. They thrive well close to human habitation and are prevalent in a great deal of cities in North America, South America, Europe, Asia, Oceania, and Africa. They are generalists, which means they do well with a wide range of foods, in a wide range of circumstances. This makes them very good at adapting to wherever they find themselves. They threaten native birds by eating, nesting, and crowding out the resources that they need.

Ebird is an invaluable resource. It provides free access to sightings maps crowd sourced by bird enthusiasts around the world.

In any case, there is not a lot that can be done that would make a big enough impact. In the United States, falconers can hunt them freely because they are not a protected species. Same goes for European Starlings, and Rock Pigeons, though caution must always be used to avoid transferring avian diseases and pests to the falconer's bird.

You can help by never feeding these birds and cleaning up after yourself wherever you go. When you do feed ducks and other waterfowl, make sure to use cracked corn, cut grapes, lettuce (or other greens) instead of bread, which makes birds sick.
