Seabird feathers and eggshells are used as bio-monitors for trace metal contamination. Eleven trace element concentrations in wing primaries (n = 21) and eggshells (n = 8) are reported herein for two resident seabirds, Bridled Tern Onychoprion anaethetus and Black-naped Tern Sterna sumatrana, at Pulau Ling and Pulau Tokung Burung, Malaysia. Metal concentration followed the pattern Zn > Cr > Mn > Sr > Cu > Se > Ba > Pb > Cd > Ga > Li. Significant positive correlations existed among all trace metals, except for Cr in Black-naped Tern and Li and Cd in Bridled Tern feathers. We also analyzed metal concentrations in eggshells, and for Bridled Tern, the concentration pattern was Zn > Mn > Se > Sr > Ba > Pb > Co > Cu > Cd, whereas for Black-naped Tern it was Cr > Zn > Mn > Ba > Sr > Se > Cu> Co > Pb. A pairwise positive correlation was significant among most trace metals in feather samples, indicating synergistic effects of two or more elements. More studies are needed to build a baseline database of trace metal concentrations in seabirds of Southeast Asia, as little research on this subject has been conducted in this region.

Avian diversity study focusing on islands in Malaysia is generally scarce compared to the unsurprisingly wealth of information on mainland birds. Similarly, Pulau Bidong is one of these islands with scarce ornithological information. It is located to the northwest of Kuala Terengganu, East Coast Peninsular Malaysia. A series of field surveys were conducted on the island between August 2014 and August 2016, using both point counts and mist netting methods to assess the bird species diversity at coastal area and within the forest canopy of the island. Unpublished data from 2006 were also added as it covers the Bidong trail area. Our results indicate that the total count is 26 species, belonging to 18 families and 23 genera. This species list is not exhaustive because the survey did not cover the main migration season from October to February, when it coincides with the monsoon season and rough weather. Further surveys will be needed to cover the nearby small islands in the archipelago.

Data on the microplastic abundance in sea turtle nesting beaches of Southeast Asia are limited. We sampled four sea turtle nesting beaches in the northern and southern coastal areas of Terengganu, Malaysia between October and November 2018, to investigate microplastic abundance, shape, and colour at both high tide swash zone and dry dunes. Using optical observation, we isolated 2,489 microplastic items, belong to four types: Fibres, fragments, foam, and films. We found more microplastics at the high tide swash zone (58%) compared to the dune zone. Fibres were the most common shape (96.18%). Of the nine recognised colours found, black was the most abundant (35.64%) followed by transparent (24.53%). Of the sites investigated, those on the northern beaches had a higher abundance of microplastics. The causes of this difference were discussed. This study provides baseline data on microplastic contamination in Terengganu turtle nesting beaches. It highlights the need for further research to identify the effects on sea turtle nesting in this region
