This guards against leaving human scent trails which nest predators might utilize. Spend as little time as possible once you arrive at the nest. How long to monitor: Try as much as possible to follow a nesting attempt through to its fate. If a nest has made it to the late nestling stage try at least to make visits at or as close to the estimated fledge date as possible. We want enough recorded information to determine if a nest has definitely failed or successfully fledged young. A nest is considered successful if it produces at least one young which fledged the nest. Parasitized nests are those in which Brown-headed cowbirds have layed eggs. Nestlings and fledglings from these eggs are reared by the host parents and can result in the death of some or all of the host nestlings. Online data entry: In addition to entering data for re-sightings of color-banded birds, it is now possible to enter nest data on the Nestwatch website (address on other side).
