In a classroom
setting, each student should listen for — and
report to the class— the first robin s/he hears singing.
A teacher may
collect
all
of the observations
from the class and submit a single report. Accuracy is the most important,
so multiple reports should not be sent.
In many
years, song reports will begin near the end of February; song reports
should reach a peak during the month of March.
Robins
sometimes sing before and during migration. This is when they switch
from winter feeding and flocking behaviors to spring migratory restlessness
and territoriality. However, you can usually
distinguish migrating robins from your local robins by watching their
behavior:
A single male who stays and sings all day long is almost certainly on
its breeding territory.
While
some robins may produce their first songs on their wintering grounds,
the vast majority wait until they are actually back on territory before
singing. (After all, the reason songs work so well for defending territories
is that male robins feel stressed when hearing other robins sing—so
any songs serves to break up winter and migratory flocks.
