In general, the best thing you can do for a bird nesting near a human dwelling is to try to minimize the disturbance—stay at a respectful distance, minimize foot traffic, door openings/closings, and postpone and projects or construction slated for the area.
If a bird is nesting in an inconvenient place on your property, the good news is that the nesting period is not forever, and in some species may only be matter of weeks. The nesting cycle for most songbirds, robins included, is around 4 weeks from egg laying to chicks leaving the nest (two weeks of incubation, two weeks of nestlings). Try not to use the area around the nest until the young have fledged to ensure that the parents will not abandon their nest. If this is not possible, try to minimize your presence around the nest; many yard birds are tolerant of occasional disturbances.
