@talentryto- That is a good question. When I decided that I wanted to attract the Western Meadowlark to my yard, I let the grass that was already growing there go to seed. I also sprinkled in some grass seed that I got from a lawn and garden store that produced thick, coarse grass.
Though I don't know much about different types of grasses, I think that most varieties will produce seeds over time if you don't mow it down or trim it. The coarse types of grass also work very well, because they seem to produce a lot of seeds as well as sturdy stalks that birds can perch on.
