Tiny wasp helps prevent first global bird extinction in Britain for 60 years (rspb.org.uk)

Original Title too long. Edited from: "Tiny wasp helps prevent the first global bird extinction on British soil for 60 years"

What a delightful article. Really impressive how they discovered the wasps to be successful in controlling the scale insect, without having any adverse impacts on other species and shipping them 10.000 km during covid.
