Scientists learn things, and share what
they learn with other scientists, by recording their data. Every single
time that Nancy Newfield handles a hummingbird, she fills out a data
sheet about it.
Nancy Newfield records
data after capturing a male Rufous Hummingbird that already had
a band on his leg.
This is the form Nancy
fills out whenever she captures a hummingbird that was already
banded. The form she fills out for unbanded hummingbirds is white,
but most of the information she records is the same.
Look carefully at the data sheet. To read a band number, Nancy must
use her magnifier. Where it says Capture, how the bird was captured,
the letters NTO stand for Net, Trap, or Other. Sometimes an unusual
hummingbird is noticed by a feeder watcher a few days before Nancy bands
it, and remains for days, weeks, or months afterwards. That is what
the "Date Detected" and "Date Departed" mean. Can
you figure out what the other items on this form mean?
