Aside from feeders and water, mixed plantings will attract a wide variety of birds. My lot has numerous canopy trees, understory vegetation and shrubs, some open areas, and some dense evergreens and thickets of things like Crabapples for cover and berries. And several gardens with a mix of many native perennials and grasses, and annuals that make seeds and harbor insects for the birds. As previous posters stated, attracting insects is important because 90% of terrestrial birds raise their young almost exclusively on insects, such as the larvae of moths and butterflies. The best way to nurture a healthy population of insects is to plant woody plants that are native to your region. Although most people don't think it looks tidy, and are usually compulsive about cleaning up dead wood, it's very attractive to all cavity nesters to leave a dead tree or two standing and even dead branches, if they are safely located and won't drop on the house or deck or anything. Birds also love to perch on dead lower branches in trees. My back yard is much more naturalized than the front and I've left about 10 or so dead pine tree snags standing back there, some of which are old enough to have multiple woodpecker holes. This year there are White-breasted Nuthatches and Eastern Bluebirds nesting in the dead snags that I've noticed so far! :)

Oh, I am sure it will be fun. Yesterday evening one dived down into the yard, flew under the shade sail over the pond and snatched a bee of of a flower. I am sure once they have babies to feed, that will be a common occurrence. They fly so fast, darting and diving in what looks like a very wreckless manner. They are in pursuit of insects so they don't follow a straight line when they fly. The next couple of months should be quite interesting!

I wasn't able to see. I'll try again tomorrow.

I find the birds definitely like to have a somewhat sheltered area where they can perch, feed, etc.. Think of a small clearing between some large mature trees with a couple smaller trees or large shrubs to perch in. This blocks them from the wind and also makes it tougher for predators like hawks to attack. Bird baths are especially popular during warm dry days, and the birds are fussy about the bath being full of fresh clean water. I have a heavy, old rough concrete one that is probably more than 70 years old. I've never had a heated bath, but would imagine it would be very popular on freezing days as water would be frozen elsewhere. I also have wooden suet poles for woodpeckers and other birds that can use them. And hummingbird feeders too. Now if only they would eat more of the berries and crab apples.....
