to Challenge Question #4:
Which Crane-Kids Wear the PTTs?
we said only three PTTs (satellite
transmitters) were available for the 2005 ultralight chicks. We asked: “Which
3 birds from all the HY2005 chicks would you pick to wear satellite transmitters
(PTTs)? What are
for each pick?”
turns out that TWO (we goofed) transmitters were available for the
ultralight chicks. They went to #502 and #520. (In
addition, HY2005 DAR chicks #527, #528, and #532 have
PTTs.) How does the team of WCEP scientists choose the birds? Sara
works on the team. She explains some reasons here:
But students Katie and Marcus made
terrific recommendations. They give
us all a lot to think about. We'd also like to commend Marcus for
"It's too bad there is not money for more PTTs,
because any of the Whoopers being led by the ultralight who seemed
slower or weaker in any way might also benefit from having the extra
means of locating them, in case they fall behind during the upcoming
I would put the special transmitters on the following three chicks:
#508: It mainly stays with the big group, so that way we could know
where most of the birds go.
#509: He was a really big troublemaker at the beginning and later
became one of the best fliers in cohort #2. It would be a good
one to track
because it might get into trouble somewhere.
#516: He kept getting hurt on the way to Florida and needed a lot
of help. Now he has made a lot of improvement, but you never know
going to get hurt or what he's going to do next.

I've read, it seems that the three female Direct Autumn Release (DAR)
birds, Jumblies (#527), Poe (#528), and Maya (#533), got the
PTTs. If I were the scientist, I would have chosen to give the PTTs
DAR birds, because they cannot be observed from an ultralight on
their migration--they will, instead, be following Sandhills. I would
necessarily have given them all to the female birds, though. Perhaps,
the male, Waldo
(#532), was a better flyer or was stronger than the three females,
so he seemed more likely to make the journey without trouble. If
the case, then, I would have given all the PTTs to the females, too.
