I am sure you have wondered if eastern bluebirds have difficulty feeding their young in the spring when temperatures are low a rainy weather dominates the weather for days on end. Actually, bluebird parents can sometimes find it hard to find enough insects and other invertebrates to feed their seemingly insatiable nestlings during times when these important food items are not moving about.
If you suspect this is happening in your yard, you can offer the adult bluebirds a number of supplemental foods. Here are some of the food items you might try: mealworms, fruits and berries, sunflower hearts and suet. Some bluebird enthusiasts even feed bluebirds scrambled eggs during these trying times.
Experiment with different foods until you determine which delicacies are favored by your bluebirds and then focus on feeding the bluebirds only their preferred foods.
Your feeding efforts can actually save the lives of many young bluebirds. However, even if the parents don’t actually need additional food to meet the demands of their young, the extra food you provide will most likely be gobbled up by other birds. In the meantime, you will sleep better knowing that you did all you could to ensure a new generation of bluebirds lived through a potential food shortage.
