Lucy68 - I meant to add that I have a variety of birds that hang out in my backyard. House sparrows, common finches, white crowned sparrows, mourning doves, etc. I have a big mulberry tree that they nest in. And they find holes in my brick exterior to nest in. They don't really care for the front yard at all - even though there is a nice tree in the corner. I usually only see the hummingbird in the front, so I'm focusing on her.
