I noticed two magpies flipping around my green ash tree this morning. Then I noticed what all the flipping was about. They were chasing a squirrel.
The magpies had a plan. They kept the squirrel in between them. The squirrel would run down the tree to find one magpie at the bottom. The squirrel quickly moved to the opposite side of the tree so the tree was between him and the magpie. As the magpie moved to go around the tree the squirrel ran up the tree until it met the magpie who was guarding the top of the tree. All of this took place in the first 3 meters of the tree.
I was surprised that the squirrel seemed to be wanting to leave the tree and run on the ground. Finally, the squirrel did leave the tree and I thought he would be a goner. However, the one magpie flew just behind the squirrel and didn't seem able the hit the squirrel from above. The squirrel ran under a fence and it was game over as the magpie had to fly over the fence and by that time the squirrel had disappeared.
I noticed one of the magpies sitting on the fence with it's mouth wide open so the squirrel gave them a good run for their money.
I have never seen or heard about such a conflict. Magpies are usually satisfied with something much easier.

Another Sneaky Merlin Story
We have a foot bridge which crosses the Red Deer River at the River Bend Golf Course. There are two large cement girders which support the bridge. The bridge is about 150 meters long.
In the summer there are hundreds of cliff swallow nests on the girders. The birds find it easy to attach their nests to the cement girder. Since the bridge obviously crosses the river there is a tremendous insect population. This makes it ideal habitat for the swallows. There is also a bank swallow colony on the river bank at one end of the bridge. So in July there are hundreds of birds around this bridge.
Now I get to the merlin. I found a merlin sitting on the bridge railing one evening. I also noticed that the swallows where swarming overhead and making an awful racket. One hunting tactic that merlins use is to get under a flock of birds . The birds try to fly up and away from the merlin. All the merlin is waiting for is for one bird to drop out of the flock and then the merlin dives and catches the bird. Birds that are old , sick or young will become exhausted and drop down to find a perch. This merlin didn't bother to fly and keep the birds rising. He just sat on the bridge rail waiting for a meal to drop out of the sky for him. Very smart birds!

Close Encounters with a Merlin
I have always admired the merlin with its rapid wing beat and exuberant flying patterns. The merlin is a small falcon with streaked underparts, the male with a blue gray back and female with light brown back. The merlin winters in central Alberta. My residential district in Red Deer usually has a resident merlin for my viewing pleasure.
A few days ago I had a new exprience with a merlin. A female flew by me at eye level a little more than arms length from me. Super experience.
I was out about 10:30 AM for a walk. The merlin buzzed a spruce tree on the opposite side of the street. There were several house sparrows in the spruce but they did not flush...just made a racket. The merlin quickly darted over the house and disappeared. So I thought well that's interesting and I resumed walking. I had walked about 10 steps when I heard the merlin coming again. ki ki ki! This time the merlin flew right by me at eye level. I could clearly see all markings.
What was she up to? After my shock I realized I was standing beside a large spruce tree which had house sparrows in it. I suppose the merlin wanted to use me as post to try and flush the sparrows. The sparrows didn't buy the trick. They squawked but did not flush and the merlin disappeared over the house.
I'm sure that the merlin caught breakfast shortly as she was intent on scaring something out of the trees where it could be caught.
Another hunting technique used by the merlin is to get under a flock of bohemian waxwings. The waxwings rise to get away from the merlin. Sooner or later one of the waxwings will tire and drop out of the flock. The merlin hones in on the hapless individual and like a bullet contacts the falling bird and the merlin has its prey.
