population research published in the journal <em>Annual Review of Environment and Resources<\/em> in May. <\/p>\n\n\n\n<p>The review, entitled<em> The State of the World&#8217;s Birds<\/em>, showed that more than 5,200 different species of birds\u2014just shy of half the world&#8217;s total\u2014are known or suspected to be declining. About 39% (around 3,800 species) are relatively stable, and fewer than 700 species show increases. Among birds on the IUCN Red List of Threatened Species, almost 400 birds worldwide had their conservation status change for the worse in the past three decades (moving from vulnerable to threatened, or threatened to endangered)\u2014five times more than the number of bird species with an IUCN status that has changed for the better. <\/p>\n\n\n\n<p>&#8220;After documenting the loss of nearly 3 billion birds in North America alone [according to a 2019 study published in the journal <em>Science<\/em>], it was dismaying to see the same patterns of population declines and extinction occurring globally,&#8221; says review coauthor Ken Rosenberg, a conservation scientist now retired from the Cornell Lab of Ornithology. <\/p>\n\n\n\n<p>The review points to disappearing and degraded habitat\u2014stemming from climate change, urbanization, agricultural intensification, and international trade\u2014as the leading driver of bird declines worldwide. In a note of hope, the authors cite a 2020 study indicating that restoring just 5% of converted habitat in priority areas around the world could avert 60% of likely extinctions. <\/p>\n\n\n\n<div class=\"wp-block-group sidebar-alignright has-lightgray-background-color has-background is-layout-flow wp-block-group-is-layout-flow\">\n<h2 class=\"wp-block-heading\">Reference<\/h2>\n\n\n\n<p>Lees, A.
