Apirat Iamsiri and George A. Gale (2008) Breeding habitat use by the globally near-threatened Hume's Pheasant Syrmaticus humiae in northern Thailand was assessed in the Doi Chiang Dao Wildlife Sanctuary, perhaps the best remaining habitat for the species in the country.  We modeled its microhabitat preferences in evergreen forest using MANOVA, principal component analysis, and logistic regression.  At least 5 groups of birds were observed in areas from 1365 to 1560 m in elevation.  Hume,s Pheasant tended to use areas containing larger-diameter and taller pines more frequently than areas with oaks or other evergreen tree species.  Areas with higher levels of herbaceous species richness below 50 cm were preferred over dense and uniform grassland which may have been related to their ability to detect predators or to their diet and/or foraging behaviors.  As this habitat is relatively common above 1000 m and the number of detections was low, available habitat appears not to be saturated with pheasants.  The reason for the apparent low numbers requires further investigation.  It is also possible that Hume,s Pheasant uses densely vegetated areas and steep grassy/rocky slopes but remains undetected; therefore significantly more telemetry data will be required to adequately assess their fine-scale habitat use.

Key words: Hume's Pheasant, Thailand, Doi Chiang Dao Wildlife Sanctuary, Habitat use.
