Anyone else here into this? I've been feeding wild birds for a couple of years now and gotten a few DDFers hooked. I've also spoken to people recently who've wanted to get started now that they're stuck in quarantine.
The main thing I've found is to attract the biggest variety of birds you need to put out a variety of foods. That generic mixed bag of bird seed has its place, but most birds prefer certain types of food and have a preferred way of eating. The more you cater to their whims, the more birds you'd get.
At the moment my feeding station consists of 5 different feeders plus a bird bath, and I've observed 24 different species to date:
3 kinds of finches (american goldfinch, house, and purple)
4 kinds of sparrows (chipping, house, tree, and white-throated)
3 kinds of woodpeckers (downy, hairy, and red-bellied)
American robin
Black-capped chickadee
Blue jay
Carolina wren
Common grackle
Dark-eyed junco
European starling
Gray catbird
Mourning dove
Northern red cardinal
Northern mockingbird
Pine warbler
Tufted titmouse
White-breasted nuthatch
Unlike your pictures, I have you beat with species count..
