This causes lower breeding success due to chicks being dislodged and not surviving their first flight.

They increase their breeding success with age and experience, until around the age of 15, when senescence seems to set in.

Rabbits live in warrens that contain two to 10 other individuals living in smaller groups to ensure greater breeding success.

Appropriate height and density are important factors for this species' breeding success.

Weather conditions are a key factor in the annual breeding success of White-fronted Geese.

In 1999 the first nest was discovered but there was no breeding success.

At undisturbed sites nests and broods are rarely attacked, as reflected in a high breeding success.

At undisturbed sites, nests and broods are rarely attacked, which is reflected in the high breeding success.

Evidence of age is noted in order to estimate seasonal breeding success.

This would also explain why the poor breeding success was first noticed in birds nesting away from buildings.
