lanius excubitor การใช้

Some studies suggest that the northern shrike ( " Lanius excubitor " ) sings in winter often imitating small passerines that may be preyed upon when lured within reach.
It is closely related to the great grey shrike, " Lanius excubitor ", which it was previously considered conspecific; where they co-occur, they do not interbreed and are separated by choice of habitat.
With some other species from the Lanius genus, like the great grey shrike ( Lanius excubitor ), the bull-headed shrike is known to thorns so the food can be ripped into bite-sized pieces more easily.
It is similar in appearance to the great grey shrike " Lanius excubitor " and the southern grey shrike " Lanius meridionalis " being predominantly black, white and grey, with the males having pink-flushed underparts.
