Our backyard has been alive with birds this year. They seem to like our vegetation as well as the occasional birdseed and crumbs provided by us. We heard about a study on urban birds through the Cornell Lab of Ornithology. We decided to participate. It was very interesting. The first day we only saw a pair of Mourning Doves. We knew we have House Finches and Sparrows sometimes. We hypothesized that it was the time of day or the absence of food. We filled the bird feeders the next day and waited. We saw a few more birds. We then changed from afternoon to morning and voila more birds. Apparently the birds like the early morning or early evening in our yard.
