When Rufous migrate to the far eastern edge of their breeding grounds their path intersects the western migration of the Ruby-throats. This usually happens in mid-late May.
"Migrating Rufous only here a couple hours feeding on nectar in feeder. Only the second time we have seen that species. Normally only the Ruby throated ones stay and breed," wrote Garry from James River Bridge, Alberta on May 14th.
