Abstract

Vegetal food is the most important resource for herbivores. The study of food consumed by bird community in Indonesia, especially in urban environments is needed to provide an overview of the ability of City Parks to support bird communities. The aim was to determine the urban park vegetation in the Lapangan Banteng park as a potential food source for urban birds, especially frugivores, nectarivores and granivores. The study was conducted in September until December 2018 . Data were analyzed using Rstudio and ImageJ. The results showed that there were 7 species of birds consisting: four species of granivores (Passer montanus, Streptopelia chinensis, Lonchura punctulata, and Pycnonotus aurigaster) and three species of frugivores (Psittacula alexandri, Dicaeum trochileum, Treron vernans) which were observed to use plants as food resource Lapangan Banteng park. Birds used 30% of trees (Syzygium polyanthum, Melaleuca leucadendra, Ficus benjamina) and 70% of herbaceous ground cover (Arachis pintoi., Phoenix sp., Pennisetum purpureum, Axonopus compressus, Cynodon dactylon, Cyperus rotundus, and Eleusine indica). The availability of sufficient natural food in nature will have an impact on both bird conservation and the environment. The availability of natural food will improve bird conservation and ensure the sustainability of urban biodiversity.

Abstract

The main mode of communication in Anura is acoustic signals, but environmental noise can hinder effectiveness signal transmission and reception. The adaptation to noise is by visual signals. This study was conducted to determine the density, the type of visual signals detected, and whether there is an influence of environmental noise and conspecific density on the prevalence of Leptophryne borbonica population displaying visual signals. This study was conducted by descriptive method with purposive sampling technique. The data taken was in the form of the number of individuals with visual signals, the number of individuals vocalizing, and the noise of the surrounding environment. The data was processed using the Solomon Coder and analyzed by Poisson regression. 159 individual frogs were found in 40 plots during observations, with the density of individuals in each plot being 3-8 individuals with noise range of 45-74 dB. Noise significantly affected the display of visual signals in a population, while conspecific density did not affect the output of visual signals.
