This study was conducted to clarify the characteristics of bird communities between before and after forest fire in tropical deciduous Dipterocarp forest of Mondulkiri protected forest of the northeastern Cambodia from January to April 2009. The DBH distribution of trees were different in each DBH class. Most of the trees (> 80%) were belong to < 30 cm DBH. After the forest fire, coverage of understory layers were dramatically decreased by the fire. Total 64 species of birds were recorded, and 64 and 46 species of birds were observed before and after the fire, respectively. Observed number of individuals of bee-eaters, treepies, kingfishers, lapwings, herons, junglefowl, peafowl, prinias and warblers were decreased after the fire. The decrease of those species would be related with the change of habitat condition, such as decrease of water amount and understory coverage. For the management and conservation of junglefowls, peafowls, prinias and warblers, understory vegetation should be maintained in Mondulkiri protected forest, northeastern Cambodia.

본 연구는 캄보디아 동북부에 위치한 몬둘킬리 보호림내 열대낙엽활엽수림지역에서 우기와 건기에 조류군집의 특성을 파악하기 위해 실시되었다. 연구지역내에 생육하고 있는 수목은 대부분 흉고직경 30㎝ 미만이었으며, 엽층의 피도량은 우기가 건기에 비해 모든 엽층에서 높은 것으로 나타났다. 특히 하층 식생과 상층 임관의 피도량에 있어서 큰 차이를 보였다. 총 84종의 조류가 관찰되었으며, 시기별로 살펴보면 우기에 68종, 건기에는 52종의 조류가 기록되었다. 물총새류와 백로류, 솔새류, 탱기물떼새류, prinias 등의 조류가 계절적으로 우기와 건기 사이에 가장 큰 차이를 보이는 것으로 나타났다. 본 연구를 통해 조사지역의 숲은 건기와 우기에 하층식생 및 상층임관 피도량의 급격한 변화를 보였으며, 이러한 서식환경의 변화에 따라 조류 군집의 종 구성 및 특성에 큰 영향을 주는 것으로 판단된다. This study was conducted to clarify the characteristics of bird communities between rainy and dry seasons in tropical broadleaved deciduous forest in Mondulkiri Protected Forest of the northeastern Cambodia. Most of the trees in the study sites were belong to small DBH (diameter at breast height) classes which were less than 30㎝. All the average foliage profiles were higher in rainy than dry seasons in the study sites. Total eighty four bird species were recorded in the study sites. Also, sixty eight species were observed in rainy season and fifty two species were in dry season. Kingfishers, herons, warblers, lapwings and prinias were significantly different between rainy and dry seasons. Characteristics of bird communities seem to be strongly effected by changes of habitat condition, such as decrease of coverages in understory vegetation and canopy.
