Be aware there is often considerable variation in a nest of a particular species, depending on the individual, circumstances, location and available materials, and sometimes nests are started by one species and taken over by another. For detailed descriptions of nest construction and egg identification, see Nest and Egg ID (also with links to photos of nests, eggs and young.) * = Occasionally found, but not definitive. More ID links below.

I would rather live in a world where my life is surrounded by mystery
than live in a world so small that my mind could comprehend it. Harry Emerson Fosdick
