      I live in central Illinois and have noticed this year we have a large population of Eurasian Tree Sparrows at our feeders, they outnumber the house sparrows greatly and appear to dominate feeding from the feeders, forcing the House Sparrows to feed from my home made platform or the ground. Is this common for the Eurasian Sparrow to dominate?
