![]() L’efficacité des nichoirs peut être évaluée en examinant les paramètres de reproduction des oiseaux dans les nichoirs pour déterminer si les données sont comparables à celles des cavités d’arbres.Ĭette recherche sur les nids artificiels de calaos a été menée dans le parc national de Budo-Su-Ngai Padi, en Thaïlande, depuis 2003. Les nichoirs sont un outil de conservation permettant d’augmenter la disponibilité des nids. Our two target species do not equally benefit from nest boxes. The study results suggest that reproduction parameters of hornbills in nest boxes are different from natural cavities in many aspects. The average life cycle of the fiberglass nest box is about 11.38±4.23 SD years. Eight nest boxes so far have been utilized by hornbills: six by Great Hornbill with 58 nesting successes and two by Rhinoceros Hornbill with 1 nesting success. The results also showed that the Great Hornbill prefers to select a large nest box than a small one: 37.3% and 17.3%, respectively (the two binomial proportions test gives: Zc = 3.4, P < 0.00068 < α = 0.05). The study results indicated that the proportion of nest occupancy of Great Hornbill breeding in natural nests was higher than nest boxes: 48.9% and 31.4%, respectively (the two binomial proportions test gives: Zc= 4.01, P < 0.0006 < α = 0.05). These nest boxes were monitored from 2004 to 2021. Twenty nest boxes were installed between 20. There were two designs small nest box: 50 x 49 cm at base and 95 cm height, and large: 65 x 70 cm at base and 95 cm height. The nest boxes were constructed from fiber-reinforced plastic. This project aims to increase the breeding propensity of two large species of hornbills the Great Hornbill ( Buceros bicornis) and the Rhinoceros Hornbill ( Buceros rhinoceros) that coexist in the study area, by utilizing nest boxes. The hornbill artificial nest research was conducted in Budo-Su-Ngai Padi National Park, Thailand since 2003. The efficacy of nest boxes can be assessed by examining the breeding parameters of birds in nest boxes to see whether data are comparable with tree cavities. Nest boxes are a conservation tool for increasing the availability of nests.
