"Report
Cards" for Cranes in Training

In
August, before most of us are back in school, the WCEP
chicks are already getting report cards! They don't get graded on reading
or math. But like us, they do get graded on the important skills
needed
to face some of their big challenges in life. Of course, the crane team
doesn't call these crane report cards. They call them "cohort
data sheets." For what
subjects do they get scored? What kinds of grades do the cranes get?
What does a crane "report
card" look like? Find out, and then and grade two cranes.
Subjects
and Tasks
Cranes get "graded" in two subjects:
- Attention
to handler
- Attention
to aircraft
Grading
System (.pdf )
Like our A-B-C-D-F system, cranes can get 5
scores, or grades:
5 |
Very
positive |
Crane
is attentive, follows handler/ aircraft closely, easily moved into
pen. |
4 |
Positive |
Crane
follows handler/ aircraft from a distance, can be led into pen. |
3 |
Neutral |
Crane
tentatively follows handler, will approach aircraft once it has
stopped moving. |
2 |
Negative |
Crane
shows no anxiety but ignores or will not follow handler/ aircraft,
difficult to move into pen, leaves handler to forage in wetland. |
1 |
Very
negative |
Crane
displays anxiety or fear, will not approach handler/ aircraft, must
be forced in or out of pen. |
Other
Grading Categories
Flying
As the chicks learn to fly, researchers keep track of how they're
doing in a
precise way. They record the baby cranes' progress at taking off and
flying. The cranes get marks for these time and distance tasks:
- Run/flap
distance (how far the crane must run and flap before getting up in the
air)
- Flight
duration with aircraft (how many minutes the crane can fly with the
Ultralight before tiring)
- Flight
duration without aircraft (how many minutes cranes stay up when observed
flying on their own)
Social and
Health Notes
- Position
each crane holds in the hierarchy (dominance order or pecking order)
with its cohorts
- Alliances
the crane holds with other cranes — that is, which cranes
it spends the most time with
- Whether
it has foraged in a wetland with its handler
- Whether
it has foraged in a wetland on its own
- Notes
about any medication or treatments the cranes receive.
- Notes
about when
the
birds get treats, where they roost, and so on.
A
Crane Report Card

|
Use
the pilot's notes and the grading system above to decide:
- How would you score
chick #10 on this day?
- How would you score chick #11 on this day?
- How
do your scores compare to the pilot's? Explain.

Questions
- If you
were keeping data on the WCEP cranes, what information would you
want
to record?
- Scientists
could record many different things, such as exactly how many items
of natural food each crane is eating,
what times the cranes preen, sleep, feed, and bathe, what vocalizations
each crane makes, and so on. 0..Why do you think the crane data
sheet doesn't include all these things?
- How does
this information help the team decide whcih birds get PTTs for satellinte
tracking in addition to their radio transmitters? How to divide birds
into two groups when two wintering sites are used?
- If
you were to keep a data sheet about your own or a friend's pet,
what data would you record?
National
Science Education Standards
- Science
investigations involve asking and answering a question and comparing
that to what scientists already know about the world.
- Scientists
use different kinds of investigations depending on the questions they
are trying to answer.
- Scientists
develop explanations using observations (evidence) and what they already
know about the world.
