The gender-specific nestbuilding--say, females alone build Bluebird nests, and beautiful Oriole pouches, while male Cardinals occasionally assist--break human conventions in construction, where males dominate. The stunning variety of nests, from flat Mourning Doves' to cupped Warblers' to covered, protective Carolina Wrens', to no nest at all for Cowbirds, Nighthawks, and Whip-Poor-Wills.
Some birds, certain warblers or vireos, use their guano to seal the edge of the nestcup.
Others like Cormorants deposit freely and unintentionally.
Much can be learned about bird behavior by studying their nests, for instance, Phoebes'
brilliant fly-catching, in the air, takes help from their partners to feed growing broods. (I must check if I have this right.)
Occasional mistaken photos, like the one for Orioles,' not showing the characteristic pendulous pouch that I only see in the Fall, once leaves have left the trees overhanging our two-lane roads, where they often build. I suppose the motorway forbids enemies from glancing up at the inviting nest, having to find it from an angle, as I do--or, usually fail to do until empty.
In Richmond, MA, we had nesting Pileated Woodpecker--impressive, resonant pecking--about one hundred feet away in a partly dead tree. Our house had a second-floor deck on two sides that gave us visual access to the Pileateds. ( )
