Finding migrants is one of the most exciting aspects of visiting Bangkok's parks for birding and any visit during the dry season is likely to turn up Asian Brown Flycatcher, Taiga Flycatcher, Brown Shrike, Black-naped Oriole and Common Kingfisher. However, this is also an excellent place for finding much rarer migrants, particularly in September/October and March/April when species such as Yellow-rumped Flycatcher, Forest Wagtail, Siberian Blue Robin, Asian Paradise Flycatcher and many others are frequently found as they pass through. Rarer migrants which have been found here include Ruddy Kingfisher, Siberian Thrush, Blue-winged Pitta and Thailand's first record of Hartert's Leaf Warbler. On a good morning here during migration the birding can be very good indeed.
