On Friday 11th July 2014, the Young Ospreys that nest on Bassenthwaite in the Lake District National Park, Cumbria, UK, are ringed and fitted with a satelite tracker. they are ringed by Pete Davis, a licensed bird ringer, and the satelite tracker is fitred by Roy Dennis. Roy is theonly person in the UK, licensed to fit satelite trackers to birds of prey. The tracing is part of the Bassenthwaite Osprey project, to see whereabouts in Africa the young migrate to, before returning hopefully to the UK to nest.Ospreys recolonized the Lake district in 2001, after an absence ovf over 150 years. In the last fourteen years of breeding over half a million people have visited the project to view these spectacular fish eating birds.

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.

Leucistic Antarctic Fur Seal pup, Arctocephalus gazella, South Georgia, South Atlantic Ocean. Leucism is a general term for the phenotype resulting from defects in pigment cell differentiation and/or migration from the neural crest to skin, hair or feathers . This results in either the entire body surface or patches of the body surface having a lack of cells capable of making pigment.
