Abstract

The Cabadbaran Mangrove Eco-Park (CaME) intends to rehabilitate and establish eco-tourism through nature immersion and birdlife watching. However, baseline assessment of avifauna is lacking. Thus, this study aimed to identify the composition of diurnal bird species present in the designated mangrove eco-park, determine the diversity, dominance and evenness of the mangrove avifauna, and compare the bird species richness in the three sites. A total of 36 avian species representing 24 families and 9 orders were recorded during the study. Among the 373 individuals documented, 181 were found in abandoned fishponds which is 49% of all bird individuals; while C. hybrida, T. stagnatilis, and E. garzetta were the most abundant species. Shannon-Wiener diversity index revealed that mangrove site (H’=2.78) was the most diverse among the three sites which can be attributed to the presence of lush vegetations. Conversely, dominant species were recorded in the abandoned fishponds which were composed of migratory species mostly. There was a significant difference of species richness in mangrove site compared to other sites since species richness was highly influenced by vegetations. Moreover, this study also documented the first scientific record of migratory species in the area, which could be one of the stopovers of migratory species. Henceforth, the es

菲律宾卡巴巴兰市指定红树林生态公园的日间鸟类物种

卡巴巴兰红树林生态公园(come)打算通过自然沉浸和鸟类观赏来恢复和建立生态旅游。然而，缺乏对鸟类的基线评估。因此，本研究旨在确定指定红树林生态园日栖鸟类的组成，确定红树林鸟类的多样性、优势度和均匀性，并比较3个地点鸟类物种丰富度。研究共记录鸟类9目24科36种。在373只鸟类中，有181只在废弃的鱼塘中被发现，占鸟类总数的49%;其中，杂交稻(C. hybrida)、停滞稻(T. stagnation)和甘露稻(E. garzetta)种类最多。Shannon-Wiener多样性指数显示红树林样地的多样性最高(H′=2.78)，植被丰富。废弃鱼塘的优势种以迁徙鱼种为主。红树林样地物种丰富度受植被影响较大，与其他样地相比存在显著差异。此外，本研究还首次记录了该地区迁徙物种的科学记录，该地区可能是迁徙物种的中途停留地之一。从此以后，美国人

期刊介绍： The AJCB publishes important new ideas and findings that have general implications for the scientific basis of conservation of plants and animals. It includes research papers, reports, comments, subject reviews, and book reviews in the following subjects: -biodiversity -population biology -evolutionary ecology -conservation genetics -conservation biogeography -natural history -conservation economics -conservation management practices -epidemiology -freshwater and marine biology -GIS/spatial analysis in conservation planning The AJCB is essential reading for conservation biologists, policy-makers and students.
