Bluebirds are quite tolerant of human presence but be prepared for some dive-bombing. Complete the monitoring as quickly as possible to minimize disturbance. When handling the nestlings or removing them from the nest, they should be placed in something that will protect them from the sun or wind while preventing their escape. Always check to make sure the box door is closed and records your observations. A tidy nest is built with fine grasses or pine needles with a fairly deep cup.
Adults remove fecal sacs and nests remain clean right though until fledging.
The nest generally has a flatter cup and is usually lined with feathers. Their nests can get messy before fledging. Chickadee build a nest of moss and plant down with the nest cup lined with hair. They lay 5-8 white eggs covered with brown specks. Sometimes the eggs will be buried under nest material.
