We plan to spend 4 days in Peninsular Malaysia primarily for birding (in mid-December). Upon the completion of the trip, we plan to fly out of the Kuala Lumpur international airport late in the evening. With that in mind, what are some of the places that we could visit for birding. I have come across names of Kuala Selengor, Bukit Tinggi and Fraser's Hill. We will prefer taking a local guide and don't mind staying in these places. Will be grateful for your suggestions including names and contact details of guides. Thanks!
