KL Bird Park is promising, i hope they will step up their game in terms of infrastructure and the variety of birds they showcase. Not as many birds like that of Singapore BP so manage your expectations. Highlight of the trip is the parrot feeding (be careful , you might get tiny scratches on your arm if they land on it, 2 ringgit for a cup of honey and milk) and the big bird feeding-free, aside from that not too much. Bring water, hat or an umbrella during your visit. If you have a working visa in Malaysia, better bring your paper (that with a redstamp) so you can have a 50% discount on the ticket.
