He's grown a lot. I believe when younger males have been separated from the main group or separated from individuals they start to mature more. This has been the case in Blackpool's case with the current male they have 'Raman'. He was separated from the females in the 2010 throughout the winter and although he hasn't matured a lot his face pads seem to have increased quite rapidly.

Interesting. I've wondered why Paignton's 14 year old male, Demo, still only looks 'sub-adult' despite having 3 females to himself. He spends most of his time with 2 of them. But I've read that orangs have the widest range of variation in timing of maturation among apes.
It's really only the scar round his eye that tells you that this is Gordon!
Sumatran males can in some cases, take up to 18 years before they become padded, though not always so long- depends very much on the individual, the conditions and whether there is another older male nearby which might act to supress the development.
Borneans seem to mature somewhat earlier, but within the same time-frame. I remember Twycross' original male 'Jod' who although quite small- almost stunted, was fully padded at a very early age, about 10. 12-15 is more normal.
