UN-led Task Force Issues Guidance on Addressing Unprecedented Outbreaks of Avian Influenza in Wildlife

The Scientific Task Force on Avian Influenza and Wild Birds – co-convened by the Convention on the Conservation of Migratory Species of Wild Animals (CMS) and the Food and Agriculture Organization of the United Nations (FAO) – has sounded the alarm on the current near-global spread of highly pathogenic avian influenza (HPAI) and the unparalleled scale of mortality among wild birds. Among other recommendations, the Task Force urges countries to consider HPAI as a conservation issue, plan accordingly and avoid culling measures of wild birds.

World Migratory Bird Day 2022 Theme to Focus on Light Pollution

Light Pollution will be the focus of the World Migratory Bird Day 2022 campaign.  Artificial light is increasing globally by at least 2 per cent per year and it is known to adversely affect many bird species. Light pollution is a significant threat to migratory birds, causing disorientation when they fly at night, leading to collisions with buildings, perturbing their internal clocks, or interfering with their ability to undertake long-distance migrations.

ACAP Proposes a World Albatross Day

At its Eleventh Meeting held in Brazil this May, the Advisory Committee of the Agreement on the Conservation of Albatrosses and Petrels identified an urgent and persistent conservation crisis for albatrosses and petrels. Thousands of albatrosses and petrels are continuing to die every year as a result of fisheries operations, notably by longline and trawl vessels. Considerable efforts by ACAP and other bodies have been put into researching and recommending effective mitigation measures to address seabird bycatch in fisheries. Nevertheless, in many instances these recommendations have not been fully implemented or have not been implemented at all.
