I found this particularly funny. It wasn’t like a funny accidental thing. Dude was trying to mate with the bird.

In September 2004, Walnut arrived at NZCBI’s Virginia campus, where scientists regularly breed cranes that have behavioral or physical limitations by using assisted reproduction techniques, including artificial insemination. By observing and mimicking how NZCBI’s male white-naped cranes interacted with their mates during breeding season, bird keeper Chris Crowe gained Walnut’s elusive trust. He pair-bonded with her by flapping his arms in a manner similar to the species’ unison dance, offered her nesting materials and brought her food. Once she was receptive to breeding, Crowe was able to use sperm collected from a male crane to artificially inseminate Walnut without the need for physical restraint

They had 8 chicks together.
