Hi,
Just a quick update and for anyone's interest.
I went to Nairobi National Park today with Ben Mugambi (thanks again for everyone's advice) - Ben was fabulous - knows his stuff more than inside out, and I second comments above recommending him without hesitation.
Personal highlights of today were Pangani longclaw, Madagascar Squacco heron, and topping it all off 2 white-backed night herons (been after that one for a long time...) - as well as black rhino and lion.
I would also like to push Nairobi Np as an amazing destination on the doorstep of a city - always worth visiting and a great one day trip for those who are on restricted time - I love it every time!
Thanks again everybody,
Liam
