Was playing around with a few figures about the percentage of hatching
year young (HY) to the total of birds of this subspecies I, with the
help of Dr. Jack and Mrs. Pat Fletcher, banded in the years 1993 to
1999, excluding 1997 because mostly inactive banding that year. Also the
dates when the subspecies were first banded that particular year, last
banded that year, and the first date of banding of HY birds.
