Plaintive Cuckoo (Cacomantis merulinus) is a small cuckoo species in Family Cuculidae that is mainly distributed in the Oriental Region. On May 1. 2016, one juvenile Plaintive Cuckoo was found at Somaemuldo Island, Korea ($34^{\circ}37^{\prime}38.73^{{\prime}{\prime}}N$ $128^{\circ}33^{\prime}0.44^{{\prime}{\prime}}E$). The bird was identified as C. merulinus by its morphological traits, especially primary projection, the shape of bars on tertials, and pale supercilium. These characteristics were distinctive from other similar small cuckoos in genus Cacomantis and Cuculus, during the field observation and examination of photographs. This record is the first of this species in Korea, and the northernmost record of this species.

In order to investigate the contents of total mercury in zoo animal located near in Seoul, we measured the contents of total mercury in fur and feather collected in zoo animal by the Mercury Analyzer. The contents of total mercury in mammals was $61.56\pm 20.32 \mu g/kg$, but in birds $659.49\pm 162.73 \mu g/kg$. Compared with feeding pattern, the contents of total mercury of omniverous and carniverous were detected higher than those of herbiverous in mammals, and also same as in birds. The contents of total mercury of Cuculidae and Ciconidae were detected highestly among classification of family in zoo animal, but those of Camelidae and Cervidae were detected lowestly. Of carniverous, 30.5% was higher than $1000 \mu g/kg$, but the ratio of omniverous detected less than $100 \mu g/kg$ was 45.5%, and in herbiverous 95.4%.
