This was the first time in 5 years that I had ever seen this unbelievable behavior by a Peregrine Falcon. This was a new mom since I had been following the nest, and she was a fierce as they come! With 3 chicks in the nest, she went after every Pelican, Gull, or Osprey that passed by. The Pelicans were so shocked that they lost their balance. In this case, this poor Pelican turned completely upside down as the Falcon grabbed his feet with his talons. The Pelican ended up ok and flying away but was shaken up!
