Higher mortality was observed among smaller nestlings (< 1100 g) compared with larger nestlings marked with wing tags, but not among those marked with leg bands. Wing-tagged adults were more likely (40%) than color-banded adults (28%) to be detected in a oneoff survey three months after marking and 65% of tagged birds were observed nesting. Over six months, 96% of tagged adults were resighted and there was no indication of impaired flight, with foraging movements ranging up to 30 km.
Survival rates of wing-tagged nestlings were compared with an equal sample of 58 nestlings fitted with colored leg-bands. The resighting frequency of wing-tagged adults was compared with resightings of 160 adults marked with colored leg-bands. Resighting frequency of adults, survival of nestlings, breeding behavior and foraging movements were monitored.
