In a classroom
setting, each student should listen for — and
report to the class— the first robin s/he hears singing. Accuracy
is important, so teachers should verify observations. A teacher may
collect all of the observations from the class and submit a single report;
multiple reports are not as useful.
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.
