We've had an excellent week down here at Cape Shirreff. My birthday on the
3rd was one of the most beautiful days we've had so far - calm, sunny, &
full of activity. I spent about 4 hours on the beach doing penguin band
resights, watching groups of penguins come leaping or "porpoising" out of
the water after a day at sea, then preening themselves on shore. They are
so amazing to watch when they swim. The parents then waddle up to the colony
with full bellies, call to their chicks & the chase begins. It's one of
the most entertaining spectacles in the natural world - chicks running down
their parents for food (does this seem familiar to those of you with kids
when you come home from a trip?) Right now the non-breeding adult penguins
are in the midst of their molt. It's a terrible time for the birds. They
are very vulnerable & their flippers (normally used for defense; strong enough
to break a skua's wing) are engorged with blood, soft & useless. They will
sit patiently facing a rock for 3 weeks until their new feathers grow in.
The penguin chicks are also molting from their fluffy down to adult
plumage. They look like little punk rockers with mohawks & other tufts of down
remaining. Soon they'll all look like miniature adults. The seal pups are
molting from their dark puppy fur into sleek silver adult coats. They look
beautiful & now they can devote all of their resources to getting fat
instead of thermoregulating. They are getting pretty good at swimming &
they truly own the cape right now, scurrying around in gangs, chasing penguins,
terrorizing chicks, & romping on our doorstep. They're still very cute &
make me laugh as they chase me down the beach. On the evening of my
birthday I had the good fortune of watching a leopard seal hunt & catch a pup, then
devour it. It was fascinating to watch him eat, throwing the small
carcass in the air to tear it up while flocks of Wilson's storm petrels tried to
steal small pieces of meat. Leopard seals are amazing aquatic predators.
So good, in fact, that we think one munched one of our birds wearing a $2000
satellite transmitter. His signal hasn't been transmitting & we haven't
seen him come to feed his chicks in over a week. At this stage in the game the
chicks are old enough that they will probably survive to fledge even with
just one parent. My birthday party was great. We barbequed pork chops on
the deck. Layla & Rodrigo made a delicious dinner & cake & I got some
excellent presents - store-bought, homemade & favors (breakfast in bed, a massage).
It's the best birthday I've had in a while. People down here are great - all
8 of them. We lost our camp leader, Mike, this week. He went back to
California. Very sad because he was our best chef & had an excellent sense
of humor. We have exactly 1 month left down here. Today we are doing a
chinstrap chick census - counting thousands of chicks. We still have a few
more days of diet sampling, the big chick banding fiasco (invariably on
the wettest, muddiest day of the year), & a bit more skua work. The busy
summer cycle of life will start winding down. Enjoy the end of winter up north.
Lots of love, Iris
