The young fledge or fly from the nest when they are about 26-32 days old. Purple martins raise just one brood per season with older adults nesting from May to June and subadults from June to July. Purple martins migrate to South Amer- ica in thewinter, departing Missouri by late August.

Can you paint bluebird houses? Bluebird nest boxes. Well Built: A bluebird house should be watertight, yet ventilated and with drainage holes. It should be built of a rot resistant wood, like cedar, or untreated exterior plywood. You can paint the outside a light, neutral color or coat it with linseed oil, but the inside should be untreated wood.

Do purple martins fly at night? They are inside by dark and stay inside until dawn or later. I understand that in the south it is more common for male martins to sleep outside their compartments, usually roosting in trees at night. However, female martins must stay in their compartment to incubate eggs and brood theiryoung.
