Now that the hatchlings are here, it is a good idea to put out plenty of mealworms. The adults and hatchlings need to eat frequently. The female bluebird must tend to the hatchlings almost continuously. The availability of mealworms in close proximity to the nestcam box helps the adults and hatchlings immensely.
The blue mealworm feeder cup can be seen on top of the mealworm feeder at the left. The adult bluebirds spotted the mealworms very quickly.
