We spotted this sparrow in the brush along a trail at Stu Visser Trails. At first we saw only the tail and had no idea what it was as the tail is all white. We then got glimpses of different parts of the bird. Finally, we were able to see this much of the bird. The white tail and large white wing patch makes this bird partly leucistic – absence of color in some feathers. We see this sparrow during spring and fall migration.
