Not a true sparrow, but a weaver-finch from Eurasia and northern Africa, the House Sparrow immediately began to exploit human-modified habitats after being introduced into the US. This bird has a knack for colonizing far-flung settled areas and usurping territory from native species. Many people have seen this bird cleaning up discarded scraps around fast-food restaurants.I stopped putting out seed that was scarfed up immediately by the House Sparrows, but I sure don't want to stop supplying black-oil sunflower seed, because the delightful chickadees and nuthatches like them also.
The other birds I see often on my porch are the spotted towhee (he's there right now), the beautiful Northern Flicker, who also loves the suet feeder, and this little guy, who I think is a juvenile grosbeak, but I can't be sure. His coloring doesn't look like the pictures, but look at that beak, what else can it be?
