Strength to enable the bird to hold its prey while it is being dissected. 

 Hence the habit of impaling. See Bird-Lore H, 195, where, in de-

 shows that the bird requires some object on which to impale its food 

 before devouring it. 



Appearance and Habits. — Shrikes are solitary and never abundant, but are 

 easily observed because of their habit of taking a conspicuous perch. The 

 flight is direct and generally concluded by an abrupt upward swing as the 

 bird takes its perch. Their prey is generally captured by a flight straight 

 from the perch and is sometimes impaled on a thorn, sharp twig or barbed 

 wire, or hung in a crotch. 



Song. — The Butcher Bird has a decidedly sweet, varied song of not great 

 volume; the Loggerhead is an equally ambitious but less successful vocalist.
