the big end. 
I cannot refrain from quoting a passage from Mr. 
Barrows’ paper, descriptive of the lively temper and 
habits of this bird : 
‘“‘ This species often persecutes smaller birds in a 
way which seems to imply pure love of mischief. 
One afternoon in July, when the river had fallen 
some feet after an unusual rise, I was walking along 
the lines of drift left by the falling water, and watch-

or other food from the wind-rows. A score or two 
of the little chestnut-backed Centrites were running 
about, and here and there a Teznioptera was looking 
quietly on. Suddenly I heard a chirp of distress, and 
looking up saw one of these small birds apparently 
making every effort to escape from a Tenioptera, 
which was following in full chase. The two birds 
were hardly a length apart and both going at full 
speed, doubling and dodging in a way that would 
have done credit to a bat. The chase lasted perhaps 
for half a minute, when the smaller bird alighted, 
and at once the other also alighted and began running 
about unconcernedly and picking up food. But the

was forced to alight. This was repeated so often that 
I was on the point of shooting the pursuer, when, 
without any notice, he flew quietly off, and resumed
