The last ever appearance of David Attenborough in a major natural history series attracted just over 6 million viewers to BBC1 last night, March 3.
Attenborough's Life in Cold Blood concluded with 6.1 million viewers and a 26% share on BBC1 in the 9pm hour last night - up 500,000 viewers and two share points on last week's outing, according to unofficial overnights.
The audience for the fifth and final episode of Life in Cold Blood increased throughout the hour, peaking at 6.4 million and a 28% share in the final quarter hour between 9.45pm and 10pm. The series launched with 6.7 million viewers and a 28% share in early February.
Life in Cold Blood will be Attenborough's last major full-scale natural history series - the 82-year-old has vowed to film one-off programmes from now on, including one on evolution.
Attenborough's examination of the reptilian world continued to easily win its slot against the final episode of ITV1's drama series about a fictional British royal family.
