Earlier in the year I had a nice variety of birds visiting my caged in tube feeder filled with sunflower kernel chips. I decided to try to keep the feeding going on in to the summer but stopped at one point because a group of probably about 50 house sparrows started to take over and would clean out the sunflower chips almost single handedly. No other birds seemed to work there way in except for a few finches. My question is will the same group of sparrows stay here year round? Will they ever move to another area? House sparrows are interesting to watch because they exhibit more observable behaviors than any other bird/s but they are just too overwhelming.
