Observation: Never saw this bird around here, asked the older people and they never saw it in our village either. Did research on it and we think it is a European bird called Great Grey Shrike (Lanius excubitor), it was the only one that matched our picture and bird call.
Guide to North American Birds – Northern Shrike (Lanius excubitor), "Semi-open country with lookout posts; trees, scrub. Breeds in far north in partly open or scattered spruce woods and in willow and alder scrub along streams or edges of tundra." (Source: Audubon)
