The tranformations caused by the raising urban planning generally result in a meaning reduction of the original diversity. The observation of fauna in parks as well as in remainder vegetation areas in a metropolis is a primordial step in order to analyse the current diversity in urbane environment. That is one of the reasons why a lifting of bat species of Prainha Park- RJ has been carried out. Some ecological analyses have been done. There were considered three different places of collection: Sede, Trilha and Mirante do Caet?. The results were monthly collected between april 2006 and february 2008, mist nets were used and aleatorily prepared. Each person had his weight observed, as well as his tibia length, cranium length, forearm length, besides sex, reproductive condition and capture time. The obtained result includes 19 species divided in three families: Phyllostomidae, Vespertillionidae and Molossidae, that totalizes 402 specimen. The most captured sort was Artibeus Lituratus (28,36%); the second most captured sort was Carollia Perspicillata (23,87%); the third one was Artibeus Fimbriatus (18,65%). The other bat species which were found are: Anoura caudifer obscurus, Chiroderma Doriae, Desmodus Rotundus, Glossophaga Soricina, Micronycteris Minuta, Platyrrhinus Lineatus, Platyrrhinus Recifinus, Sturnira Lilium, Tonatia Bidens, Trachops Cirrhosus, Vampyressa Pusila, Eptesicus Brasiliensis, Histiotus Velatus, Myotis Nigricans and Molossus Molossus (29, 12%). The efficiency of the capture changed from 0,0167 bat per time-net in Sede to 0,1771 in Trilha station. The region of Prainha Park has presented a diversity H?= 1,71, significant differences have been checked ( Sede, H?= 1,57; Caet?, H?= 1,21 and Trilha, H?= 0,82). The wealth of the species (Rate of Margalef) found for the Park was R= 3,0018. Te proportion between males and females has been established around 1:1, in some cases, 1:2. The community of bats of the place is similar to the communities of other localities in many aspects. It suggests that even small forest fragments are valuable for the maintenance of some sorts of barts, because these fragments offer a great deal of the resources which bats need. Another reason is that these fragments are arranged in order to make easy the utilization of the landscape
