pleasant surprises. While ovenbirds and water thrushes were frequently 
trapped in the fall, of the other warbler species only two black and white 
warblers and a single Nashville warbler visited fall traps. 
One female robin unwittingly proved to be an assistant by her jerkings 
at the string attached to the drop trap, in efforts to carry it off as nesting 
Fox Sparrow “hypnotized” on hand 
material. On the first occasion she brought down the trap so as to imprison 
a white-throat, but she persisted whether birds were in the trap or not and 
became such a nuisance that it was necessary to sidetrack her by laying out 
numerous bits of loose string, which she accepted in place of the trip cord 
of the trap. 
The close inspection one is enabled to give banded birds allows a study 
of the individual variations in colorations and markings to an extent not 
possible otherwise. For instance, the chest streakings borne by immature 
white-throats not only throw light on the relative proportions of old and 
young in the fall, but also on their order of travel in migration. This last 
varied somewhat, but in about half the instances the earliest banding was 
of an adult, as though the parent birds led the way southward, as one might 
expect. As to the proportions of adults and immature throughout these 
twenty years, in those trapped before September 21 the young have been 
62%, between September 21 and October 10 they increase to 76%, rising to 
83% between October 10 and 20, and amounting to 93% after October 20. 
The total percentage of young in the fall bandings figures 77%, or a little 
more than three young to one adult. As their eggs are variously stated to 
range from three to five in a nest, this suggests either an adult mortality
