The only difference being, that the victim then was a tercel gentle, and now it would be a white dove.
Shakespeare tells us to choose "a falcon or tercel for flying at the brook, and a hawk for the bush."
These he fastened firmly together, and set them securely within that window, by which the tercel would come to his lady.
By the falcon is always understood the female, as distinguished from the tercel, or male, of the peregrine or goshawk.
Whilst the lady yet wondered upon him, the tercel became a young and comely knight before her eyes.
The tassel, or tercel, was the male of the peregrine falcon, and was noted for its docility and gentleness.
The latter was probably called the tercel, or tiercel, from being about a third smaller than the falcon.
"male falcon," late 14c., from Old French tercel (c.1200), from Medieval Latin tertiolus, from Latin tertius "third, a third," from root of tres "three" (see three). Various theories as to why it is called this; one says it's because the males are a third smaller than the females, another because a third egg in the nest (smaller than the other two) is believed always to produce a male bird.
