0:00:23 > 0:00:26at what natural wonders he has uncovered over the years
0:00:26 > 0:00:30during is epic career.
0:00:30 > 0:00:32Even before colour TV, David Attenborough was travelling
0:00:32 > 0:00:33around the world to explore remote areas
0:00:33 > 0:00:35and find out about wildlife.
0:00:38 > 0:00:40For more than 60 years now, he has been
0:00:40 > 0:00:42bringing back amazing footage of rare animals, plants and insects,
0:00:42 > 0:00:46to audiences around the world.
0:00:46 > 0:00:49These engaging chicks are so inquisitive
0:00:49 > 0:00:52that you only have to sit down to their own level for them all to
0:00:52 > 0:00:55gather around you to try and discover what sort of creature you
0:00:55 > 0:00:57are.
0:00:57 > 0:01:01He is so influential he has 30 honorary degrees, a knighthood,
0:01:01 > 0:01:05and even had a new species named after him, including a type
0:01:05 > 0:01:11of spider, a flesh eating plant and a fossilised fish.
0:01:11 > 0:01:15No museum in the world has a complete specimen of this species.
0:01:15 > 0:01:18Human beings exterminated it in the middle of the 17th century.
0:01:18 > 0:01:21There are a lot of animals today that face
0:01:21 > 0:01:25the same fate as the dodo.
0:01:25 > 0:01:27He's used his programmes to tell people about
0:01:27 > 0:01:29different animals that need protection from extinction.
0:01:29 > 0:01:32Some of his biggest admirers include US President Barack Obama and CBBC's

0:01:36 > 0:01:39My earliest memories of Sir David Attenborough were watching his
0:01:39 > 0:01:44Zoo Quest series, which was quite a long time ago now.
0:01:44 > 0:01:46I instantly thought, that is amazing,
0:01:46 > 0:01:51that is what I want to do with my life.
0:01:51 > 0:01:52Hello.
0:01:52 > 0:01:54Attenborough often gets up close and personal with the
0:01:54 > 0:01:56animals in his programmes.
0:01:56 > 0:01:58His unique voice and enthusiastic descriptions are his trademark.
0:01:58 > 0:02:01These are greylag geese, the same species that
0:02:01 > 0:02:07Konrad Lorenz worked with.
0:02:07 > 0:02:10David Attenborough has changed the way many people see and think
