Tamarindus Indica Grove

When i was kid some 20years back, we had rented a small house and which had a nice little backyard. The backyard consisted of huge grove of tamarind trees (Tamarindus indica) adjacent to our backyard. And the space invited so many colorful avi-fauna, which as a kid me and my elder brother engaged our self into. Now since we had relocated our self from there, but when i went to refresh my memories recently, the entire back yard along with the beautiful backyard, have been ripped apart and apartments have come up. I wonder how the avi-fauna who resided there might have sustained themselves, while my memories have been completely stripped out.
