One tracks bird around about lake (8)

I believe the answer is:

titicaca

I'm a little stuck... Click here to teach me more about this clue!

'lake' is the definition.
(I've seen this before)

'one tracks bird around about' is the wordplay.
'one tracks bird' becomes 'titi' (I am not sure about this - if you are sure you should believe this answer much more).
'around' becomes 'ca' (circa).
'about' becomes 'ca' (circa).
'titi'+'ca'+'ca'='TITICACA'

Can you help me to learn more?

(Other definitions for titicaca that I've seen before include "Large lake on the Peru-Bolivia border" , "Large Andean lake" , "World's highest lake, between Peru, Bolivia" , "high water" , "high lake" .)

I've seen this clue in The Sunday Times and The Times.
