Extinction Crisis Looms for Birds, New Study Warns
A dramatic aerial clash: Ascension Frigatebirds display social and competitive behaviour above their oceanic breeding colony. Once nearly wiped out by invasive predators and habitat loss, this species was highlighted in a recent study among the world’s most functionally unique birds at risk – underscoring the need for targeted recovery, habitat protection, and ecosystem-wide conservation. © Kini Roesler
