Do all bird houses need perches?

How do you keep snakes out of bluebird houses?
Writhing across an open space such as a mowed lawn exposes snakes to predators.

Meal worms, suet, sunflower hearts, softened fruits, and cornmeal muffins can all be fed to bluebirds. Most of these will be accepted during the cold weather months if bluebirds have wintered over. But, meal worms are the best food to feed bluebirds and they will readily eat them year-round.
Do bluebirds use nest boxes in winter?
In winter, a few species of songbirds—the ones that nest in tree cavities or birdhouses in spring—will also use roost boxes to stay warm. Among them: bluebirds, chickadees, titmice, screech owls and some woodpeckers. There’s not much research on which roost boxes work best, but prefabricated boxes are worth a try.
Where do you put mealworms for bluebirds?
Once they become familiar with the routine, the mealworms should be placed inside the feeder. The location of the feeder can also be varied. Initially one can place the feeder close (~25 feet) to the nestbox. Then incrementally move it farther away (to ~100 feet) as the bluebirds become familiar with it.
