I've read some similar things about them preferring platform feeders, suet and mealworms. I'm going to put one up in a big open space in my yard where alot of birds flyover and maybe if one is out and about it will be attracted to it. I will probably put a birdbath out near there too, and maybe putting mirrors out too. I will let you know if I have any success.
I did put up a platform feeder and more suet feeders this year. The first day of the platform feeder I saw a Rose-Breasted Grosbeak. I've only ever seen one a few times before and never in my yard. Unfortunately I haven't seen that bird since then. Just this week I have started seeing a Red-Bellied Woodpecker at my suet feeders so that is pretty cool.
I forgot to add that I also read somewhere that Mockingbirds like dripping water or sprinklers. This summer when I saw some Mockingbirds they were bathing themselves in a sprinkler next to some bushes and would fly in and out of the water from/to the bushes. I did get a sprinkler and I will try that again next year too.
