Peregrine falcons return to the same nesting site each year. Some sites have been used for centuries by multiple generations.
Peregrine falcon chicks, called eyases, eat an incredible amount of food – in six days, they double their weight. At three weeks, they are ten times their size at birth.
Some peregrine falcons will use man-made structures such as bridges and skyscrapers to nest.
Peregrine falcons may travel widely outside the nesting season- in fact, their scientific name comes from the Latin words ‘falco’, meaning ’hook-shaped,’ possibly referring to the beak or claws, and ‘peregrinus’, meaning ’to wander.’
