Modelling and mapping potential hooded warbler (Wilsonia citrina)habitat using remotely sensed imagery

Hooded Warbler (Wilsonia citrina) Science Article 1


Modelling and mapping of hooded warbler (Wilsonia citrina) nesting habitat in forests of southern Ontario were conducted using Ikonos and Landsat data. The study began with an analysis of skyward hemispherical photography to determine canopy characteristics associated with nest sites. It showed that nest sites had significantly less overhead canopy cover and larger maximum gap size than in non-nest areas. These findings led to the hypothesis that brightness variability in high to moderate resolution remotely sensed imagery may be greater at nest sites than in nonnest areas due to larger shadows and greater shadow variability related to these gap characteristics.
