I sing in a choir <a href=" http://www.aaapp.org.au/order-zoloft.pdf ">children taking zoloft for ocd</a> Not that solitude is the first thing that comes to mind when you&rsquo;re standing in the middle of a penguin colony on an Antarctic shoreline. When I visited, in early February, there were thousands of birds packed tightly on every rock, both shy gentoo penguins and the bolder adélies, which seemed happy for us to wander among them, our cameras clicking furiously at the grey fluff-ball chicks tapping their parents&rsquo; beaks to be fed. Adult penguins nudged each other into the sea and &ldquo;porpoised&rdquo; through the water like leaping salmon, their oiled white feathers gleaming silver in the sun. Later in the trip I saw chinstrap penguins on Livingstone Island, looking just as if they were sporting old-fashioned motorcycle helmets.
