This is Bird Note. She was an incredible astronomer, master of the stars,

extremely knowledgeable of landscapes and geography, an expert forger and healer,

an amazing naturalist. She was in tune with the birds and their calls, notably the hoot of a bard owl.

Harriet Tubman was a heroic abolitionist in the cause to end chattel slavery and an expert

birder. On the underground railroad, Tubman used the song of the bard owl as a signal to let freedom

seekers know that she had arrived. Her call let them know when it was safe to come out. She mastered

the sound and used it throughout the underground railroad. After learning this story, I was inspired

to learn this hoot myself in homage to Tubman. It was so smart to use the bard owl song as a signal.

It's easily disguised, it's nature. She knew to use it at night when it would blend in with other

nighttime sounds. But those in the no knew it was Tubman. And when they heard it, it was an important

signal on a journey to freedom. This week is Black Birders Week. To learn how to participate,
