  1. Use lights low in spectral red to reduce mortality from artificial lights

    A study on an oil rig in the southern North Sea on three nights in October 2007 (van de Laar 2007) found that the number of migrating birds circling the rig was 10-50% of the number expected when the majority of external lights were replaced with ‘low red’ bulbs (150-2,500 birds observed circling vs. 750-5,000 birds expected). Low red bulbs emit lower levels of red light than standard bulbs. Attracted birds were mainly songbirds, waders and wildfowl and expected numbers were estimated based on previous observations and calculated from the number of migrating birds recorded on nearby islands, the number observed from the rig and the weather conditions.
