CAMBODIA HIV+ couple making handicrafts. Toul Sambo village is a resettlement area outside of Phnom Penh. Set in rural tranquility surrounded by paddy fields, it is a peaceful place for its residents. A Caritas Cambodia project, it has two focus groups who live there. One group is largely HIV+ and used to reside in a Phnom Penh slum called Borey Kila, until they were evicted by the government who wanted to develop the land for offices and shopping malls. The other group consists of those made homeless when a river's bank subsided in their village, destroying their homes. At the home of Kea Nimal and Kem Sokhorn, both HIV+. They are very industrious working at home making paper bags and ornaments, some with recyclable materials. They can earn $12-$15 per 5-day working week, and live quite comfortably in their attractive home with TV, motor-cycle and other conveniences. They say they are much better off than in the crowded and unhealth slum of Borey Kila in Phnom Penh where they used to live. They get regular orders for the handicrafts they make. They stay healthy by taking ARVs, which are supplied free of charge by the Hope Organization. PHOTO by Sean Sprague

Chinstrap penguin (Pygoscelis antarctica) chick head detail at colony on Useful Island near the Antarctic Peninsula. There are an estimated 2 million breeding pairs of chinstrap penguins in the Antarctic peninsula region alone, perhaps as many as 7.5 million breeding pairs in all of Antarctica. Their name derives from the narrow black band under their heads which makes it appear as if they are wearing black helmets, making them one of the most easily identified types of penguin. Other names for them are "Ringed Penguins", "Bearded Penguins", and "Stonecracker Penguins" due to their harsh call. They grow to 68 cm (27 in). The average adult weight of a Chinstrap Penguin is 4.5 kg (10 lbs). Weight can range from 3 to 6 kg (6.6-13.2 lbs), with males being slightly larger and weight varying based on where the penguin is in the breeding cycle. Their diet consists of krill, shrimp, and fish. On land they build circular nests from stones, and lay two eggs, which are incubated by both the male and the female for shifts of five to ten days. They can also breed on icebergs, though they prefer non-icy conditions. The chicks hatch after about 35 days, and have fluffy gray backs and white fronts. The chicks stay in the nest for 20?30 days before they go to join a creche. At around 50?60 days old, they moult, gaining their adult plumage and go to sea. The Chinstrap Penguin was first described by German naturalist Forster in 1781. Its specific epithet was often seen as antarctica, however a 2002 review determined the genus Pygoscelis was masculine, and hence the correct binomial name is Pygoscelis antarcticus.
