A large number of rats have been found around the sooty tern colony on Ascension Island – with evidence of having fed on chicks.
Now one has been captured on video, probing round a nest at night while a tern refuses to move away.
The video has been published on the Ascension Island Conservation group’s Facebook page, which reports on a project by researcher Emily Dawson to study the black rat.
It says: “Emily Dawson, an MSc student from the University of Exeter, has found a high density of rats in the area surrounding the sooty tern colonies most with large quantities of sooty tern chick remains in their stomachs.”
