We’d like to change your mind about house sparrows.

“Boring.”
“Invasive.”
“Trash birds.”
“Vicious little monsters.”

Not everyone has nice things to say about house sparrows (Passer domesticus). But at Wild Animal Initiative, we love these little birds with a big reputation. To us, they’re on the cutting edge of groundbreaking scientific research that could ultimately make the world a better place for many different animals.

This winter, we’re launching a field research project to understand how varying environmental conditions such as water availability, noise level, and land use affect the welfare of the house sparrow. Our research team will record audio and video at a variety of sites where house sparrows live, and then analyze their behavior and vocalizations.

It’s the first study of its kind and will help advance the emerging field of wild animal welfare science.

By welfare, we mean the aggregate quality of an individual’s subjective experiences over a given time period. This can also be called “well-being” or “quality of life,” and it’s a highly neglected research area in the biological sciences. While other fields have historically asked questions about how to preserve species or habitats, wild animal welfare science asks questions about what life is like for individual animals, and how we can help them responsibly and at scale.

The house sparrow research project has the potential to produce groundbreaking data that will be useful to scientists in numerous fields, including urban ecology, animal behavior, and climate science. We expect the data to be relevant to scientists who study additional species too, such as other sparrows or songbirds. 

We hope research like this will influence policies on urban development and wildlife management so that animal welfare is taken into consideration.

We at Wild Animal Initiative envision a future in which even house sparrows — a species that is typically ignored at best, and despised at worst — will be understood and valued as individuals. A world where people want to help wild animals like these common birds, and they’re equipped with the research they need to do so responsibly. Each research project like this one takes us one step closer. Donate to accelerate science that helps wild animals.

So what do you think? How many stars would you give a house sparrow?

House sparrow is great beautiful little bird

They are intelligent, cute, loving birds. They deserve better. They have personality, they're loyal, they know love, like us humans.

Let’s know more

This adaptive bird is known to live near us and can spread disease, can steal food, can contaminate food. What compulses it to always be near us? While I agree this bird is primarily a pest, it can also potentially be an indicator species of factors affecting all life, and human health.

House sparrows make nutritious meals for local coopers and sharp-shinned hawks around here.

Destructive

I don't know the full scope of your research, or why you chose English Sparrows, but in the U.S. these birds are a threat to our native song birds. Like starlings, they attack and kill other birds in their nests. They arrive in huge flocks and make survival more difficult for the natives.

Killing our Native Birds

Brenda B.

Don’t feed millet and you might keep your nesting, native birds safe. These nasty birds kill adult and baby bluebirds, tree swallows, chickadees and more. Please don’t encourage them to nest especially if you have nesting boxes up.

Five stars! These little survivors deserve more respect.

These birds are common in my yard and neighborhood

Wreaking havoc

Paula Z.

I have been involved in native cavity nester conservation for over two decades. House sparrows, a nonnative species, wreak havoc in nestboxes and purple Martin rigs. Our native cavity nesting birds cannot compete and that is why urban areas are overrun with them. I consider them the garlic mustard of the bird world.

Beautiful birds

Jaime A.

House sparrows have great intelligence to adapt to new surroundings. They spread worldwide only to start retreading due to human pollution. These beautiful birds need protection.

Sparrow 5 stars

Love this little bird

Linda L.

I live in a small city. The English sparrows have been coming to my feeders for 41 years. They are social creatures who eat and bathe and fly together. I’ve planted 4 trees in my yard to accommodate them. I have learned to love them.

South of Houston suburbs, house sparrows are infrequent feeder visitors. They feed and leave when larger doves and blue jays show up to feed.

Year-round visitors

Stephen W.

I have a lot of house sparrows visit my yard all year along with over 100 other species of birds. I feed them all. I also have many squirrels, rabbits, opossum and raccoons. My yard is alive and I love it.

These vicious little monsters basically taunted my backyard bluebirds from their former home 👎

NOT a bottomless brunch

I JUST filled the feeders this morning and the house sparrows already cleaned me out! Seed is $20 a bag!!1 😩

Nothing to see

Ash T.

I want to add beautiful birds to my life list. Every chirp today was just another house sparrow! They’re SO boring. 🥱

Basic but cute

John K.

They’re not bright and colorful like the cardinals or bluejays but they’re fun to watch hopping around the backyard!
