REMOVING A CUP NEST OF A TURDUS MIGRATORIUS FROM THE TERRACES OF A BRICK CHIMNEY DOCUMENTED WITH CELLPHONE, 2010
1. The Migratory Bird Treaty Act of 1918 prohibits the removal of all listed species or their parts (feathers, eggs, nests, etc.) from private property such as trees or buildings.
2. Birdnest Morphology, aka Comparative Caliology
Professor Rennie, in his little volume entitled “Bird Architecture,” written almost a century ago, took his cue from Aristophanes, an ancient Greek dramnatist, and introduced the birds as artisians accordinig to the form or nature of their nests: miners, masonis, carpenters, basket-makers, weavers, tailors, cementers, felt-makers and parasites; also grounid, platform and dome-builders […] —Burns, Frank L.

3. Behavior of Turdus Migratorius: nest-building, vocalizations
The nest is most commonly located 1.5–4.5 meters (5–15 ft) above the ground in a dense bush or in a fork between two tree branches, and is built by the female alone. The outer foundation consists of long coarse grass, twigs, paper, and feathers. This is lined with smeared mud and cushioned with fine grass or other soft materials. A new nest is built for each brood, and in northern areas the first clutch is usually placed in an evergreen tree or shrub while later broods are placed in deciduous trees. The American Robin does not shy away from nesting close to human habitation. [ . . . ]
In addition to its song, the American Robin has a number of calls used for communicating specific information. When a ground predator approaches but does not directly threaten, Robins will make a PEEK!! tut tut tut tut… warning call, often preceded by an explosive seeech each-each-each. When a nest or Robin is being directly threatened, another he-he-he-he call is used, which sounds like a horse’s whinny.
