Age‐dependent prospecting and recruitment to a breeding colony of Short‐tailed Shearwaters Puffinus tenuirostris
In a small colony of Short‐tailed Shearwaters Puffinus tenuirostris , monitored annually since 1947, many of the young ringed as nestlings returned to their natal colony for one or more years before breeding for the first time. These ‘prospectors’ were first recorded at 4.1 ± 0.1 (range 2–7) years o...
