Abstract

The environs of Taungoo Township, Bago Region are one of the high biodiversity areas in Myanmar, locating eastern side of the high mountain ranges of Middle Yoma. The dense of every green and deciduous forest in the middle Middle Yoma were logging since 10 - 20 years ago. The birds inhabiting in that area have to refuge in suitable habitats nearby. The resent status of bird species is needed to assess the diversity of birds with the respect to distribution and seasonal variation after the construction of Yangon-Nepyitaw, Myanmar after twenty years ago. A total of 50 species of 27 genera, 22 families under nine orders were recorded. That represented 44 resident species (32 terrestrial species and 12 water bird species), and 6 species of migratory birds (1 terrestrial species and 5 water bird species). As habitat utilization, 24 bird species in paddy fields, 21 species in scattered trees, 33 species in wetland and 25 species in forest habitat types were investigated. Some species used more than one habitat types. According to the assessment of abundance categories based on the calculation of individual numbers of the birds, abundant category (3 species), common bird (1 species), frequent category (5 species), uncommon category (3 species) and rare species (28 species) were categorized. Hence, bird community was still sustainable in this area. In the aspect of conservation status, all recorded bird species were under least concern categories, according to the IUCN Redlist in the study area.

Highlights

The Middle Yoma Mautain Range is running along the middle of Myanmar country from north to south tip
A total of 50 bird species belonging to 28 families under10 orders were observed during the study period
Among the 50 bird species, 17 species of waterbirds belong to five migratory species and 33 species of terrestrial bird belong to one species of migratory bird were recorded in the study sites (Table 1)

Summary

Introduction

The Middle Yoma Mautain Range is running along the middle of Myanmar country from north to south tip. The evergreen forests and misdeciduous forest, including valuable trees of teaks and many other trees grow dense in this range. The forests were depleted during the time of Yangon-Nepyitaw highway road construction. In the Middle Mountain range of Myanmar, the forest ecosystem is fantastic with very high species diversity. The canopy cover is very thick and we cannot see the sun even at the noon time in the forest. After depletion of those forests, the dependent forest fauna species face with habitat loss, habitat fragmentation consequencely. The question is that where the forest dependent species including birds move to
