The most interesting experience of the morning remains
to be chronicled. I was returning over the intervale and within
two hundred yards of the railroad when a Shrike (L.l.migrans)
started from a maple and flew off up the road, carrying a bird in
its bill. It alighted first on a fence post, next on a brush heap
near the railroad. I got within twenty yards of it each time. As
I was approaching it it worked busily and nervously, tearing at
its prey and eating portions of it. Finally it circled back past
me and flew out into a large field where it alighted on a fence
post. Before I could get near it again it flew a fourth time
leaving its victim which I found was a Bank Swallow. It had eaten
the head completely off and had impaled the loose skin of the lower
neck on a sharp upright splinter that projected above the post.
After examining the Swallow I walked off a few rods when the Shrike
immediately returned to it and carried it off across the road to a
small half dead willow that grew by a wall within fifty yards of a
house. I followed and had the great pleasure of watching the
Shrike impale the Swallow on a short, sharp stub of a dead twig.
It performed this operation precisely in the manner of the Northern
Shrike that I saw hang up a Field Mouse at Ball's Hill a dozen or

minutes often fluttering its wings either to keep its balance or
