Robins are noted for defending their nests fiercely against intruders of all sorts.
Nesting robins are dangerous only if you are a worm or a bug.

How to Make a Robin Nest BoxRobins build nests in trees or on other structures. Some of us naturally think that the robins that make their nests in the most natural settings will have better success than those that nest on houses. Sure enough, once in a while a baby robin crashes to a hard cement patio and dies when it first fledges from a nest built on a porch light. Baby robins in tree nests have far softer landings in the branches below their nest branch.Nest Boxes Can Help Protect Baby RobinsA problem even more dangerous to baby robins than falling is predation, especially by American Crows. Most crows are reluctant to come too close to buildings, so robins that nest on porch lights, window sills, eaves, and other spots on houses are usually safe from them. Robins nesting on buildings are often easy to study during their nesting period. If you want to study nesting robins, getting them to nest in a box or other structure can be good for you AND good for the robins!Problems associated with robins nesting on houses:Robin adults may attack people who come too close. If you put up a nest shelf, you might want to locate it on a side of the house that gets little human traffic.Robins may discover their reflection in a window, and start attacking it. This happens as often with robins nesting in trees as on houses. To deal with that issue, see Help! There's a Robin Hitting My Window!Baby robins may crash to hard cement below. If you want to put up a nest platform above a deck, patio, sidewalk, or other hard surface, a few days before the babies are due to fledge you might want to put a wheelbarrow or wagon filled with something soft below.
The bird you are refering to is not a Robin at all. This bird is a non native bird that has come to America and is now competeing with Robins and other native birds for nesting areas.
Yes, robins do and can fly.
Robins! Robins! Robins!
You could collect some bugs or leave some mealworms around in sight, but that would attract other birds that might disturb her nesting. Ms. Robin can take care of herself. Watch her and enjoy, without worrying.
No robins can swim but they can fly
Actually Robins will nest in boxes but they won't use boxes designed for the Tit family. Use a template for an open fronted nest box & place it somewhere under cover & away from prying eyes (including yours). Robins will abandon their nest if they are disturbed. You need to also make sure that it's also inaccessible to predators such as Jays, Magpies, Cats etc. A regular supply of live mealy worms will also help. Templates for both types of box are here: http://www.bto.org/nnbw/make.htm American robins are not cavity nesters, but the EUROPEAN ONES MAY.
