What
are the temperatures at the Observation Posts today? As you
track these over the next few weeks, you may want to revise
your predictions. |
As
you look at these current snow-cover maps, ask yourself, "Are
robins likely to return here or begin singing yet? Why or
why not?" |
When
did robins arrive at the NOPs last year? When did they start
to sing? Do you think they will follow the same pattern this
year? Why or why not? |
