I've seen exactly the situation multiple times. A couple memorable ones were: two crows versus a Merlin in South Florida. It's hard to know which was the aggressor here, they took turns. Initially the crows were diving at the Merlin which retaliated. This went on for about 10 minutes before the Merlin moved on. A migrant heading south likely over the Gulf. The crows residents. Another time it was a Raven versus a Peregrine in the Hills above Alviso California. Once again they switched places first The Raven going after the Peregrine then the reverse. Back and forth back and forth. Both of them masters of the air.

One time in September, Mike Force and I were at Jericho Park on the west side of Vancouver BC's West side. There was a tall long-dead cottonwood snag on its south side containing a Merlin and an American Kestrel. For the next half-hour several times we witnessed these two suddenly start chasing each other. First, Merlin chasing Kestrel, return to the snag, rest, then Kestrel chased Merlin, return to snag, rest, a few minutes, rinse and repeat, the two of them alternating the chaser/chased roles at least three times. Tell me that's not play.</span></div><div dir="auto"><span style="font-size:12.8px"><br></span></div><div dir="auto"><span style="font-size:12.8px">Jericho is longer east-west than wide north-south, about a kilometer and a half long. An unwitting Cliff Swallow (remember Cliff Swallows?) entered the park at the eastern end. The Merlin immediately rocketed off to intercept it.
