1. Main path in North-West Thailand. Majority of Amur Falcon, ranged in number per migrating flock of all sexes and age-classes, from tens to hundreds makes a passage from NE (over golden triangle of Laos, Thailand and Myanmar from Vietnam) to SW direction into Eastern Myanmar. Most of sightings of migrating flocks have been observed in Chiang Rai and Chiang Mai provinces; i.e. Tha Ton, Mae Ai, Chiangsaen Basin, Doi Lang, Doi Chiangdao. This migration can be seen from mid-October.

2. Stray of singles. Only juvenile (fist-year/hatch-year)and fewer records of adult female have been observed (as southbound individual strays), in central and southern Thailand, such as Lampukbia in Phetchaburi, and raptor watch sites; e.g.Radar Hill and Khao Dinsor.
