Abstract

Of 774 Atlantic Puffin (Fratercula arctica) nestlings transplanted from Great Island, Newfoundland to Eastern Egg Rock in Muscongus Bay, Maine, 147 are known to have returned to the Gulf of Maine, of these, 36 nested at Eastern Egg Rock, 17 at Matinicus Rock, and one at Machias Seal Island. Inter-island movements between these colonies decreased with age: 44% of 2-yr olds observed moved between islands, the proportion was 25% for 3-yr olds and 14% for 4-yr olds. At Eastern Egg Rock, the average age at first breeding increased from 4.2 yr in 1981 to 5.8 yr in 1985. Pairs that nested earlier in the season were more successful in producing a fledgling than those that nested later. This study demonstrated that young puffins learn the location of their natal island sometime after they are 2 wk old, and they will return and nest at a transplant site or nearby existing puffin colony. This study also demonstrated that young transplanted puffins develop a breeding schedule associated with conditions at their release site, rather than conditions where they were hatched, i.e., a genetically determined timetable for breeding. /// De 774 pichones de Fratercula arctica transplantados de Great Island, Newfoundland a Eastern Rock en la bahía de Muscongus, Maine, se conoce que 147 han regresado al golfo de Maine, de los cuales 36 anidaron en Eastern Egg Rock, 17 en Matinicus Rock, y uno en la isla de Machias Seal. Movimientos entre islas de las distintas colonias disminuyeron con la edad: 44% de los individuos observados de 2 años de edad se movieron entre islas, asi como 25% de 3 años y 14% de 4 años de edad. En Eastern Egg Rock, la edad promedio al alcanzar madurez sexual aumentó de 4.2 años en 1981 a 5.8 años en el 1985. Parejas que anidaron temprano en la temporada fueron más exitosas produciendo pichones que aquellas que anidaron más tarde. Este estudio demuestra que las aves juveniles aprenden la localización de su isla natal en algún momento despues que cumplen 2 semanas de edad, y que ellos regresarán y anidarán en el lugar del transplante o colonia activa más cercana. Este estudio tambíen demuestra que los juveniles transplantados ajustan sus patrones de reproducción a las condiciones prevalecientes en el lugar que son liberados en vez de las condiciones de donde fueron traidos, ej., patrones reproductivos determinados genéticamente.
