英语. From 2004 to 2009, two colonies of Malachite Kingfisher were monitored by ringing the nestlings and adults, counting eggs and observing parental activity at the nests. Results show that 10 % of nests were destroyed by people in the Symphonies site as against 78 % in the Monastery site. Consequently, the number of nests available for breeding is lower at Monastery than at Symphonies. The number of fledged chicks per nest at Symphonies was twice that at the Monastery. Site fidelity is higher for the adults in the Symphonies site (26 %) than at the Monastery (11 %). This suggests that the Monastery site is less favourable to the survival of the Malachite Kingfisher than the Symphonies site. The best strategy to protect this species seems to be the maintenance of a good number of nesting sites.
