We are planning a birding trip in Kuala Lumpur between the 1st and 4th of May. We have already decided on Fraser hill and Sungai Congkak, and for the remaining 2 days we would like to choose between Kuala Selangor Nature Park, Bukit Tinggi Japanese Garden, Taman Botani Negara Shah Alam, and would be very interested in any suggestions you may have. If there are other places that are more worthwhile to visit (not too far from KL), I'd appreciate it if you guys could let me know the name of the place!
