Peregrine Falcon hunting a Merlin

This morning (18 October 2018) I witnessed a breathtaking, long-winded chase overtop the crashing waves of the Ottawa River. I was viewing from near the lighthouse at Dick Bell Park. For nearly one minute (estimate) a juvenile Peregrine Falcon was slicing and dicing its way ever closer toward a succulent meal… locked on to its target like a fighter jet. The meal wasn’t a Dunlin, or a yellowlegs…it was a Merlin! A few times, the Peregrine managed to drive the Merlin right toward the waves of the Ottawa. Each time, I was surprised to see the Merlin pop up a bit further along, desperate to gain equal altitude to the Peregrine in order to avoid another stoop attack. By the end of the chase, the Merlin appeared fatigued and flew more like a sharpie with short series of flaps followed by long glides as it made it ashore. Have other birders in this forum seen Peregrines hunting Merlins? I was surprised, and my impression at the time was it was a once-in-a-lifetime observation (luck!) Absolutely amazing drama…

Good birding
