vesper bat

Thanks for the suggestion !!

which of bat species is this.......??

I'll tell you, yet another, interesting fact, about my house being an attractive spot, for some wandering bats. First of all, check out the link, to see the photograph of the, ceiling of Drive-in, in my house :- "https://picasaweb.google.com/darvesh.singh/DropBox?locked=true&pli=1&gsessionid=WgTYWwgoRtTQ3DtJM-LYFQ#5606189839197571362" There are 100 concave depressions, on the design of the ceiling. Now, these depressions reflect and amplify even the slightest of sound. So when passing-by bats navigate through sonar, they get confused from the heavy reflections from the ceiling, and perceive the underneath of the Drive-in to be a cave. And caves are an attractive place for the bats to hunt. I have seen this behavior mostly in the night time when its cold and pleasant outside. :-)

With the information given by you gals, i add some facts and listen the story that goes this way. Recently, i am busy, with the construction of my Recording Studio. An my construction area, there are two rooms, that are intended for soundproofing and thus are constructed with all the sides closed without any windows even. So naturally these rooms are damp and cold. Say, probably some 4 to 5 months ago, there was a bat of this species living in one of these damp rooms. Could it be the same bat, if, for a moment we consider that, this bat is infected with some problem. Now, if the bat is infected, with some disease then it will not be able to compete with other healthy bats in a swarm so this one could have had, deliberately isolated itself from its competitors. And moreover my construction site is full of plants, that support insects and that what bats feed on !!! A probable question is that could this spotting be the same bat, that i have seen in one of my damp rooms ? secondly, if the previous bat was infected then could it survive for 5 months, to reappear again [ my house and the construction site are very close to each other ,just about 100 m apart ]

OK, that's interesting, i cannot tell very clearly about, bat being in trouble, as it was very stationary and just when i finished clicking the last photo it flew away. :-)

Why dear ??

id please !
