Concern about black-fronted terns

One of only two black-fronted tern fledglings produced from a colony of 60+ pairs on the upper Rangitata which was partially flooded and may have also been predated. Breaks my heart to see photos of people driving 4wds through colonies on the more stable, smaller rainfed foothill rivers in Canterbury when I see how hard these birds struggle in the more unstable high country rivers- this species is seriously on the way out unless more active management takes place
