As to “repeats” the same season as banded, the story is quite different. 
Of the various finches 24% of those banded did so repeat, although of all 
the other species only 15% repeated. Whether it has been due to their 
preponderant frequency in being trapped, or from some particular trait of 
avian psychology, the white-throats easily led the list of repeaters, doing 
so especially during the fall migrations, as though they had more leisure 
and were free from the biologic urge which is believed to play the important 
role in causing the trek north. From two to five repeats were common, and 
some individuals had as many as 15, 27, 35 and 37 recaptures to their credit. 
One, an immature bird, No. 683853, made a total of 77 visits to the traps 
from September 22 to October 22, 1928. In this period it was caught in 
three different traps, although it vastly preferred the sparrow trap in which 
it had been first caught. On three different days it was taken from traps as 
Immature White-throated Sparrow Adult White-throated Sparrow 
many as five times. Toward the end of its stay on several occasions it would 
re-enter a trap by the time its releaser had retreated to a distance of 50 
feet, even though just a few seconds before it had shrieked loudly in apparent 
fright when being taken from the trap. It grew so tame that it would feed 
energetically while one stood beside the trap, though it would flutter 
violently during the procedure of opening the trap exit and removing’ it. 
These athletic actions became increasingly injurious to its tail feathers, so 
that all of them had been broken off by the time of its final disappearance. 
In the spring of that year a north-bound white-throat had been trapped on 
May 20, and remained until June 14, in that period being captured 40 times, 
making use of six traps, though chiefly a large sparrow trap and the tilt- 
bottom trap. It would be most interesting to know whether the bird repeat- 
ing so often in the fall was an offspring of this white-throat that piled up so 
many repeats in the spring!
