Abstract

<p>We surveyed nesting Peregrine Falcons Falco peregrinus in Hiroshima Prefecture from 1988 to 2023. We compared the number of falcon nests during the first (up to 2007) and second (2008-2023) survey periods. The number of falcon nests increased from 25 to 39 in the mainland area, especially in quarries, where the nest sites increased from 8 to 23. We deduce that a recent rise in quarrying activity on the mainland increased the potential nesting sites for peregrines, thus inviting falcons to attempt nesting more frequently in quarries. Nesting sites for falcons had a high continuity rate for those on natural cliffs or quarries, but when nesting in man-made structures the continuity rate was low. No clear trend was observed in the directionality of the falcons’ nesting sites</p>
