Humboldt Penguin "Carlo"

On 10 and 11 March 2009 the Antarctic Research Trust equipped 10 Magellanic and 10 Humboldt Penguins from Islotas Punihuil in Chile with satellite transmitters. Unfortunately, two transmitters went silent after a short period of time, but the remaining 18 penguins have been transmitting their position daily ever since. Most of the animals have since left the breeding island and started their winter migration, which can last up to 7 months.

The Wuppertal Zoo Society adopted Humboldt Penguin "Carlo" travelled 700 km north within the first 40 days of his migration. Then he turned around and swam almost 400 km back. On 28 April 2009 he was approximately 330 km north of his breeding island where he first received his transmitter.

After his last transmission on 28 April 2009, "Carlo" swam further south a few days later. 55 days after receiving his transmitter he again swam within 100 km of his breeding island. Since then he has been moving north. On 8 May he was 350 km north of his breeding island.

From the 20 penguins equipped with transmitters, only 8 penguins were giving off a signal on 8 May 2009. The transmitters have stopped working with the other animals. Either the transmitters have fallen off the penguins or something has happened to them.

Locations of the remaining penguins recorded on 8 May 2009

On 12 May 2009 "Carlo" transmitted his position for the last time. At this point he was again over 500 km north of his breeding island. In the 62 days where his position could be followed, "Carlo" travelled over 1700 km in a north-south direction alone. Swimming patterns to the west and east were not taken into consideration. From the 20 transmitting penguins only a single penguin was transmitting a signal on 12 May.

Whether the transmitter got lost or something happened to "Carlo" is not known. Either way, the Zoo Society wishes their sponsored penguin all the best on his migration!
