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.
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.’
