Loggerhead Shrike

  Look at this bird, it is a loggerhead shrike, a species of shrike. It can be found Southern Ontario, Quebec Alberta, and south to Mexico. It seems normal. However there is a reason why loggerhead shrikes are often referred to as "butcher birds". This is because the shrike enjoys catching small invertebrates and impaling them on thorns or other sharp objects. This helps them tear the flesh into smaller, more manageable chunks and serves as a larder for the bird to return to at a later time. This strange feeding habit also allows the shrike to consume the toxic lubber grasshopper. The bird simply picks the grasshopper up, impales it, then waits one or two days for the toxins in the grasshopper to degrade, then it eats it.
  Shrikes are territorial, and these territories are
defended from other shrikes.
