Radio Tags Created to Help Penguins Are Killing Them

Here is why microchip transponders under the skin are also a really bad idea:

Radio tags designed to monitor endangered penguins could be killing them, say scientists.

A 10-year study found that King penguins with the metal rings had 39 per cent fewer chicks and 16 per cent lower survival rates than those fitted with transponders under the skin.

It is feared that flipper bands, used to identify the birds, cause physical damage and drag under the water.

Research published in Nature suggests birds with flipper bands respond differently to the climate by arriving later on Possession Island, off Antarctica, than those untouched.

Dr Yvon Le Maho, of Strasbourg University, and colleagues say the value of many surveys is questionable.

They say: “Responses of flipper-banded penguins to climate variability differ from non-banded birds.”
