Bird of the Week … Northern Mockingbird

Thomas Jefferson with his Mockingbird Dick.

Well, not sure any of you guessed this, but our 3rd President of the United States, Thomas Jefferson, had a pet Northern Mockingbird named “Dick.” He actually had several Mockingbirds at various times, but Dick was the only one he mentioned by name in his diary and apparently was his favorite. Jefferson often left the cage open in the White House and allowed him free range of his office (now the State Dining Room). Dick would perch on Jefferson’s couch or shoulder and sing or take a piece of food from Jefferson’s lips. When Jefferson played his violin, Dick would pour out his songs.

Although maybe not the prettiest of all birds, Northern Mockingbirds certainly make up for looks with their beautiful extended repertoire of songs. These birds sing endlessly, and can learn up to 200 different songs. Both the male and female sing and can mimic many other bird calls, other animals and even mechanical sounds. There is a mockingbird near my house and he sounds exactly like a Red-tailed Hawk. Many of us have been fooled by these comical birds as they imitate Blue Jays, Orioles, Killdeer, frogs, dogs and even squeaky wheels. They tend to repeat phrases 2-6 times before shifting to a new sound. Unmated males will are the most insistent singers and may sing late into the night.
