To increase the amount of available bird shelter in your yard, create a brush pile for birds to hide in, and leave things like tree snags and mud spots alone.īirds use both dead trees and mud for nesting purposes, and so keeping these natural features in your yard can make it easier for them to thrive. Native plants provide both a place to take cover from predators and a place to lay eggs, meaning that adult birds can thrive and raise the next generation in peace when they’re present. In addition to providing food, native plants can provide valuable shelter for native birds.īy planting native trees, shrubs, and flowers, you can make it more likely that birds will find a place to live in your yard and deescalate the competition between birds. Make sure that you offer supplemental food consistently across all seasons, as birds need the support year-round. That said, offering additional food sources through feeders is also helpful for native birds.Ĭonsider offering high-fat seeds and suet, as well as nectar and tree nuts. The best way to support them is to plant trees and shrubs that provide all these food sources. Native birds eat a wide range of food, from seeds to fruits to insects. Nesting places and food sources have become increasingly scarce for North American birds.īecause of this, the impact of non-native bird species on natives has been even more of a threat.īy supporting these birds with food, water, and shelter, you can make resources less scarce and reduce the impacts of competition. However, most conservationists will not remove bird nests unless they have significant experience and can do so with precision and care. House sparrows are not a protected species in the United States, and so physically removing House Sparrow nests or eggs from nest boxes is also a legal option. Ideally, your nest boxes should be closer to forested areas than they are to houses and other buildings. These foods attract House Sparrows more than other birds, and they will follow their favorite foods.Īnother way to deter House Sparrows is to place nest boxes in isolated areas, as House Sparrows tend to flock to areas with heavy human traffic. One way to deter House Sparrows is to avoid using certain foods in your feeders, namely filler grain like cracked corn or millet. You can take several steps to prevent House Sparrows from taking over your yard and your nest boxes. Thankfully, there are several humane ways to do this. Keeping House Sparrow populations under control gives native species a chance to propagate, ultimately leading to healthier ecosystems. How To Reduce the Impact of Invasive Species Like the House Sparrow House sparrows are quite aggressive in how they go after nests, and will even attack and kill native birds to steal their nests. This means that House Sparrows have been preventing native birds from using nest boxes on a large scale, making it harder for them to find safe spaces to lay eggs and raise young. The lab found that House Sparrows comprised 43% of the group of competitor birds taking nesting boxes from native species. The Cornell Lab of Ornithology recently launched a citizen science project called The Birdhouse Network to monitor the impact that House Sparrows and other invasive species have on native birds. Impacts of House Sparrows on Native Populations Since then, House Sparrows have expanded their range to encompass the entire United States. House Sparrows were introduced to the United States through Brooklyn, New York in 1851 when 100 birds were released into the wild to control insect populations and reduce the new residents’ feelings of homesickness. House Sparrows are native to Europe and Northern Africa but have since been introduced to South Africa, North and South America, Australia, and New Zealand. The Natural Range of the House Sparrow vs. They sometimes do this by depleting other species’ food sources, while other times, they prey upon native species to an extreme degree. Invasive species are non-native species that reproduce so quickly and effectively in their new environment that they drown out or stifle the development of native species. They now inhabit all of North and South America, Africa, Europe, Australia, and New Zealand. House Sparrows are considered an invasive species because they were introduced to new areas where they weren’t native and then started to outcompete native bird species.
