The slugs are tentatively identified as Berthellina delicata, a species known to occur in the Indian Ocean and the western Pacific (Gosliner et al., 2008; 2015). Their identities cannot be confirmed as there are a few similar Berthellina species in the Indo-Pacific that are not readily distinguishable by external morphology (Gosliner et al., 2008). Regardless, the present record appears to be the first of the genus Berthellina in Singapore waters (see Tan & Woo, 2010). Although the two specimens are very similar looking, the first is a darker orange with more distinct sparse white spots on its notum (see Figs. 1 & 2). Our bservations seem to suggest that the right kind of food sponge was not offered to the second specimen. It is not known if different species of Berthellina have specific prey preferences, but there remains a possibility that the two are not conspecific. Note: This is a contribution of the Singapore Comprehensive Marine Biodiversity Survey conducted by the National University of Singapore's Tropical Marine Science Institute and the National Parks Board.

We report the first record of the Asian openbill (Anastomus oscitans) in Singapore. The six birds observed at Seletar North since 23 Jan.2013 foraged on a small, flooded field and were seen to feed on apple snails, subsequently flying to roost on adjacent trees of albizia (Falcataria moluccana) on observation days. Recent southwards dispersive movements down the Thai-Malay Peninsula based on observations of large flocks in southern Thailand and Peninsular Malaysia at multiple sites is unprecedented and may represent post or pre-breeding dispersal from colonies in central Thailand or Cambodia, although the exact causes remain unclear.

All three stints were initially identified as red-necked stints. However, from the photographs, it was noted that two of them appeared taller than the third individual when standing upright. The photographs were circulated to shorebird experts in the East Asian-Australasian Flyway for confirmation of the stints’ identities. More than ten experts (the identifiers listed above) have confirmed that two of them were little stints based on their upright posture, longer and thinner bill and longer legs. These identification characteristics are also highlighted in Sonobe & Usui (1993). Bakewell (2017) provides a detailed account of the identification In summary, the adult little stint (Fig. 1, front centre; Fig. 2, back and Fig. 4) has retained some breeding plumage on the chest and clear unmarked white on the throat, also showing darker central crown and clear split supercilium; while the juvenile bird (Fig. 1, right; Fig. 2, front and Fig. 5, right) has evenly dark centred scapulars and coverts, and strikingly dark mantle, well-streaked breast side and strongly contracted dark crown with white split supercilium. The other stint (Fig. 1, left and Fig. 3), with comparatively shorter bill and legs, is identified as a juvenile red-necked stint (Calidris ruficollis). The featured observation and photographic evidence constitute the first published record of the little stint Calidris minuta in Singapore (see Lim, 2017). This record has been accepted by the Nature Society (Singapore) Bird Group Records Committee on 24 November 2017.
