BIRD STUDY 44: 176-181 Part 2 JUL 1997
Abstract:
A survey of quarry-nesting Peregrines conducted in the Republic of Ireland between
1991 and 1993 estimated that 65 quarries were occupied by Peregrines. There was
a marked east/west gradient in occupancy with most occupied quarries in the east.
Occupation of quarries by Peregrines is primarily influenced by cliff height.
