Nest description: twigs, grasses and debris. May be primarily of slender, dry stems with small leaves attached, lined with soft, wooly branch tips. May contain grass stems, plant fibers, leaves, rootlets, hairs, string and wool, lichens. Sometimes nest in wreaths on doors of houses - see photos. Not typically found in nestboxes, although they may use slot boxes and metal Purple Martin houses.

Eggs ypically oval, smooth shell, slight gloss, pale bluish white/green with sparing, delicate black (or dark brown or olive) spots/dots, speckles or streaks on the large end of the egg, forming a fine, loose ring. Occasionally eggs are unmarked. Length may vary. Eggs are typically laid in the early morning, with the first one a day or several days after nest construction ends.

After nestlings are 5 days old, they defecate on the edges, creating a filthy mess, in a halo or wreath effect.
