This shrike prefers open or semi-open habitats such as moorland, heathland, taiga, steppe, agricultural areas with scattered trees, and clearings. Look for it perched prominently on elevated points like fence posts, utility wires, tall shrubs, or the tops of small trees.

Spotting a Great Grey Shrike often involves looking for its characteristic upright posture on an exposed perch. It has an undulating flight pattern. Its calls include harsh chattering, trills, and whistles, and it is also known to mimic other birds. The prominent black 'mask' across its eye is a key identification feature. Observe its hunting behavior, which may involve impaling prey.

Great Grey Shrikes are diurnal, active during daylight hours. Resident populations can be observed year-round in suitable habitats. Migratory populations are best seen during their spring (March-May) and autumn (September-November) migrations, and throughout the winter months in their wintering grounds.
