After second look, we recognize a bird sitting on the fence is a House Sparrow. The bird is well known as invasive species in our areas.

Invasive species means that House Sparrows may compete and even kill native species in our areas.
Several species could be killed by House Sparrows are:
- Eastern Bluebirds (Sialia sialis)
- Tree Swallow (Tachycineta bicolor)
- Carolina Chickadee (Poecile carolinensis)
- Northern Flicker (Colaptes auratus)
- Downy Woodpecker (Dryobates pubescens)

In our urban area, we may see aggressiveness of House Sparrow to kill birds in their nest, then take over the nest.

ReplyDeleteHello,
ReplyDeleteYes, the House Sparrows are not native to the USA. They seem to be all around the world. Thank you for linking up and sharing your post. Take care, have a great weekend.
...I'm sorry to hear that it is invasive for you!
ReplyDeleteI don't think we see them here but I have learned something about them now. Thanks for the info!
ReplyDeleteI know they can be agressive.
ReplyDeleteI'm not that fond of them.
ReplyDeleteThey’ve become rare in our area now, but I still remember how common they were in my childhood.
ReplyDeleteWow, I didn’t realize House Sparrows could be so aggressive 😟🐦 It’s sad to think of them threatening bluebirds and chickadees. Definitely makes me appreciate the importance of protecting native species. 🌿
ReplyDeleteInteresting post, thanks so much for sharing it with us
ReplyDeleteHave a nice day ♥
The sparrows have returned her, after som years missing. I have never noticed that they have done harm to other birds, especially not woodpeckers. They usually sit together in a bush all day, gossiping. They eat seeds and insects.
