We Hate Meeces to Pieces?

As on many remote islands, rodents are decimating ground/burrow-nesting birds on Marion island. Marion island is an uninhabitated, sub-Antarctic island in the Southern Indian Ocean. The island is home/a breeding location, used by albatros, penguins and petrels etc. House mice were accidentally introduced to Marion, by fomer seal hunters. Mouse populations have subsequently boomed and these rodents now feed on eggs, chicks and even some adult birds. The Mouse-Free Marion programme aims to totally remove these rodents (https://www.theguardian.com/environment/2023/mar/21/world-biggest-single-eradication-operation-remove-mice-marion-sland). The intention is use a fleet of helicopters to drop rodenticide over the entire island. This technique has worked in other places, such as the Antarctic's South Georgia. This approach, however, is not without some difficulties. Rats and mice are burrowing animals and can get into some relatively inaccessible locations. Ingested Warfarin also causes internal bleeding in any animals that ingest it. Dropping this rodenticide from helicopters, may have to be repeated several times. Using this technique on Gough Island has, for example, not, thus far, eradicated all rodents. Rat and mouse killing is, unfortunately, a prerequisite for conserving endangered remote island populations of seabirds.
