6 THE? A UDU BON, (BU YE Pei 
A brown thrasher, mentioned earlier as having succumbed to a sudden 
cold wave, had been trapped first cn September 30, 1925, and remained at 
the station until November 5. During these five weeks he was trapped 31 
times and became so tame that he would lie quietly on one’s hand for many

of actual, persistent, fear in these repeaters has been a continuing surprise.

but because he made an inquisitive entrance into the garage through a 
partially open door. As to the warblers, it had been expected that those 
species more generally seen on the ground, as ovenbirds, water thrushes and 
Maryland yellow-throats, might be trapped, but without special warbler 
traps the capturing of most of the other of the twelve species have been
