I just located (2pm) the Jaeger at Rigden Res on the west side of I-25 harassing gulls here. Looks like the same bird. Only a couple miles from Timnath as the Jaeger flies. Rigden is part of Arapaho Bend Natural Area at the eastern terminus of Horsetooth and Strauss Cabin Road. This bird is still around and may be bouncing between here and Timnath. So don't give up yet! I'll post updates if I see the bird again.
