Here is a phenomenon that we are already familiar with at our own local Home Depot: house sparrows finding a place to live in big box-type stores. And why not? As the article notes, these places give a few bird species all they need - food (in the form of bird seed, etc.), water, nesting areas and few predators.
One thing that surprised me about the story is the accompanying box of text that says House Sparrow populations are declining. Wonder what this is based on? I had assumed that House Sparrows, as well as other urbanized birds such as European Starlings, were and are expanding rapidly as urban and suburban habitats provided by humans expand.
