Hatching success can vary by beach and year, due to changing environmental conditions and rates of nest predation.
Nest monitoring can also provide extremely valuable information about nesting behavior, habitat selection, and nest predation.
Another risk faced by antbirds in fragmented habitat is increased nest predation.
High rates of nest predation may select for smaller clutches to reduce the parental investment in a single nesting attempt.
Species responsible for nest predation are not generally known.
Since crows do not seem to mind human development, it was suggested that the crow population increase would cause increased rates of nest predation.
Therefore, the human relationship with crows and ravens did not significantly increase nest predation, compared to other factors such as habitat destruction.
Since nest predation is common, several adaptations have evolved in this species.
Sage grouse apparently have high rates of nest desertion and nest predation.
Another reason could be nest predation by coyotes and/or mink.
