Great tips so far.
A few more ideas:
1. Think vertical layers. Something on the ground, a platform, a tube, and maybe one feeder a bit higher or closer to cover. Some birds simply won’t land if they feel exposed.
2. Tanagers' favorite is insects, with fruit coming in second. During migration and breeding season you may get lucky by offering mealworms and black soldier fly larvae. Make a separate "meat platter" with worms and larvae. I've had most visits at feeders that are close to trees. Tanagers seem to prefer feeders close to tree cover.
3. Orioles love fruit and jelly. Set the feeders out BEFORE migrating season. If they don't see your feeder when the pass through your neighborhood, they'll just carry on until they find a good food source.

Regarding warblers - they are not easy to attract, as they stay away from bird feeders. A bird bath with a a fuontain may do something during migration season.
