It is not wicked at all, just Tree Swallows in their mating ritual. When mating, the male performs a number of flybys while his mate raises her head backwards as seen in this photo. The male then mounts, and using his beak grabs the crown of the female.

"Something wicked this way comes" is a line from William Shakespeare's play Macbeth. Spoken by one of the three witches, "something wicked" is a reference to Macbeth. Actors and theater people often consider it bad luck to mention Macbeth by name while inside a theater, and instead call it "The Scottish Play" or "Bard's play".

Although superstitions by definition are deemed irrational, it is amazing how common they are. Superstitions are applied to acts related luck, prophecies, spiritual beings and predicting future events. The other day I wished someone a happy birthday and got scolded for saying it one day too early. Irrespective of our intentions, there will always be someone offended...

• - It's my birthday tomorrow.
• - Well, Happy Birthday!
• - [Scoldingly] You can't say that, you ruined it!
