“…The number of sampling stations in each habitat cover type was based on a previous study in Fiji whereby a minimum of five stations was sufficient to record 95% of the bird diversity in a forest habitat (Naikatini 2009). In this study, we noted all birds seen or heard at every survey point (Naikatini 2009;Reid et al 2019).…”

“…was located along the Savuione waterfall track. The forest is secondary regrowth due to shifting subsistence agriculture and traditional tree removal practices (Reid et al 2019). The dominant tree species include native trees such as Pterocimbium oceanicum (Sterculiaceae), Bischofia javanica (Phyllanthaceae), Syzygium malaccense (Myrtaceae), Vitex vitilevuense (Verbenaceae) and Dendrocnide harveyi (Urticaceae) (Keppel et al 2022).…”

“…We used bird point count data collected from forest and grassland habitat cover types on Viti Levu, Fiji and asked if avian species diversity and community assemblage differ across years and habitat cover types. Reid et al (2019) carried out a shortterm study during July in 2016 and found consistency of point count data across survey days. We compared (1) avian species diversity and community composition, (2) the proportion of different foraging guilds (insectivore, nectarivore, granivore, frugivore, omnivore), and (3) the distribution status (endemic, native, introduced) at the species level and the individual level across habitats.…”

“…Furthermore, 49 (74%) of the 66 native land bird species are extant on Viti Levu island. The habitat associations for some of these native and endemic species have briefly been discussed by Gorman (1975) and Reid et al (2019) including some observations and records (Clunie 1984;Watling 2001;Tabudravu 2009) but patterns of occurrence in different habitat types across years has never been quantitatively analysed. To better manage the extant avifauna in forest and anthropogenically modified grasslands in Fiji, we urgently need comparative data on patterns of avian diversity and abundance between habitat types.…”

Context. Habitat loss is a global problem and in Fiji >50% of the land area once covered by forests has been converted to grasslands and agricultural land. About 99% of Fiji's endemic biodiversity and 80% of the land bird species have been identified as forest species. Aims. In this study, we compare forest and grassland sites and test for consistency in avian diversity, abundance, foraging guild, and distribution status (endemic, native, introduced to Fiji) over a 5-year period (2016-2020). Methods. We surveyed bird communities using the point count method with a 100 m radius and 7-min observation period per site. Key results. A one-way analysis of similarities (ANOSIM) analysis showed significant differences in species composition and bird abundance between the forested habitats and grassland habitats. A general linear model test showed significant differences in foraging guild composition and distribution status between forested and grassland habitats. There were no significant differences between the three forested sites (primary montane forest, secondary old-growth forest, old-growth mahogany plantations with regenerating native species), while grassland sites had stronger annual change in species composition. Implications. Forest cover, irrespective of whether these forests are of primary or secondary nature, therefore plays an important role in maintaining the native and endemic land bird species and other biodiversity in oceanic island ecosystems such as Viti Levu Island, Fiji.

“…Fiji's avifauna are diverse and hold significant cultural value (Watling, 2013). About 34 of the known 66 land bird species characterized in Fiji are endemic, with majority residing in the forest (Reid et al, 2019), but knowledge regarding their ecology and behaviour remains rare (Naikatini et al, 2022). It has been documented that more than 60 % of Fiji's native forest was deforested, creating a mosaic of primary and secondary forest (Olson et al, 2010).…”

Forests are increasingly becoming fragmented and declining due to natural causes and human-induced activities. The latter creates an imbalance which put the survival of vulnerable species such as those of avifauna at risk. Honeyeaters are group of birds common in Fiji, with certain species strictly confined to specific habitats. This study is an attempt to compare the abundance and foraging behaviours of three sympatric honeyeaters namely Kikau wattled honeyeater, Orange-breasted myzomela and Giant honeyeater at two contradicted sites (USP campus and Colo-i-Suva Forest Reserve). The survey was carried out using point count method along three different transect routes of approximately 2 Km on each study sites . A higher species diversity and abundance was observed in Colo-i-Suva Forest Reserve than in USP campus. Kikau wattled honeyeater are more populated at USP campus due to adequate nectar-producing plants. Whereas both Orange-breasted myzomela (highly adaptable bird species) and Giant honeyeater (forest specifics) are frequent in Colo-i-Suva Forest Reserve. All exhibited a wider range of foraging techniques across forest vertical strata and plant species, except for Giant honeyeater (not observed). The statistical analysis showed that there is a significant difference (p < 0.05) in abundance as well as between the number of honeyeater species in both sites across the forest vertical strata. However, there is no significant difference in the foraging behaviour and the number of honeyeaters found foraging on diverse plant species (p > 0.05).
