The welfare of the birds must always have the highest priority. Do not cause stress to the birds or expose them to danger by approaching too closely or interfering with their natural behaviour.
Adjust your behaviour to the location. Walk slowly, speak quietly, drive cautiously. Watch from a distance.
Approach nests carefully and do not stay nearby for long periods. Your visit may assist predators to find eggs or young; your continued presence may drive parents away.
Do not harass ground birds by repeated disturbance.
Accept good distant views of a bird rather than risk causing stress by approaching too close.
Do not harass rare or vagrant birds by long periods of intense observation. They may be in strange territory and vulnerable to exhaustion and predation.
