Food, shelter and water ...

Look up what your local birds eat and plant those things - flowering things for hummingbirds, seeds and berries for other birds.

Shelter - dense bushes so small birds can hide from predators.

Water, if you dump it daily to avoid mosquito breeding.

Feeders will attract birds, but they also provide a place where predators will have a high kill rate. Look at all the complaints about hawks catching birds at feeders.

Tall trees, preferably with bare branches, and other tall open places to perch where they can look at the terrain.

If you are at ground level, that could be tough. I am at the rooftop level of my neighbors and I see tons of birds. They come so close and are not afraid of us.

A good bird feeder and a suet feeder might do the trick. We get a ton of hummingbirds because of our lobelia plants.

Awesome advice guys, thanks!

gracie01 do you have any suggestions for a heated bath? In my head I have a very funny image of a little bird jacuzzi!

All though it's expensive and there are cheaper ones, This is a heated bird bath. I think Houzz also has some for sale, and you may find something useful when you search "heated bird bathes" in the Houzz search bar. Although a bird jacuzzi would be funny!

I like your suggestion lime, it's a good price and isn't too flashy. I've often been wary of bird baths as some seem a little extravagant in their design, or worse, too bland!

Glad I helped. There are ones cheaper, but no sure how good quality they are.

Check on Amazon for heated bird baths too.

Trumpet vines attract hummimgbirds as well. I had hummingbirds coming to my holly holcks this year

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.....

My feeders are between the house and some trees. There is no 'swooping' room for hawks to feast on my feeder visitors. I have had a nesting pair of Red-shouldered next door for the past few years and, although they come close, I have never seen them near my feeders.
