salt at the lower end of their possible concentrations, helping to lower the amount of ingested salts. The amount of sodium imposed by this sort of diet is still relatively heavy and can create complications when considering the less tolerant chicks. Adult Adélie penguins feed their chicks by regurgitating the predigested krill, which can impose an excessive salt intake on the chicks. Adult birds address this problem by altering the ion concentrations while the food is still being held in their stomachs. By removing a portion of the sodium and potassium ions, adult Adélie penguins protect their chicks from ingesting excessive amounts of sodium. Adélie penguins also manage their salt intake by concentrating
1031:-discoloured coastal areas (red/brown patches in areas with no snow) in the satellite images, and augmented their findings with field surveys in areas where no good satellite images were available or where the presence of multiple penguins species was suspected. The results of field surveys were only used if they had been done within the previous four years. This census found an estimated 3.79 million breeding pairs in 251 distinct breeding colonies, including more than 40 that had never been surveyed before, a 53% increase over a census completed 20 years earlier. The colonies are distributed around the coastline of the Antarctic land and ocean. Colonies have declined on the

When they had succeeded in pushing one of their number over, all would crane their necks over the edge, and when they saw the pioneer safe in the water, the rest followed." Levick also detailed the mating habits of Adélie penguins.

poking their heads to and fro in their usually absurd way, in spite of a string of howling dogs straining to get at them. "Hulloa!" they seem to say, "here's a game – what do all you ridiculous things want?" And they come a few steps nearer. The dogs make a rush as far as their harness or leashes allow. The penguins are not daunted in the least, but their ruffs go up and they squawk with semblance of anger.… Then the final fatal steps forward are taken and they come within reach. There is a spring, a squawk, a horrid red patch on the snow, and the incident is closed.
496:. This coat of feathers is typically silvery-grey (darker on the head), though some birds are much darker overall. Within 10 days, the chick moults into another set of down feathers, this time all dark smoky-grey. Once they have moulted a third time, 7–9 weeks after hatching, the immature birds are similar to adults in appearance, though they tend to be smaller with a bluer tinge to their upperparts and white (rather than black) chins and throats. They lack the full white eye ring of the adult until they are at least a year old.

or 28 °F/-19 °C or -2.2 °F), the parents take turns incubating the egg; one goes to feed and the other stays to warm the egg. The parent that is incubating does not eat and does not even leave to defecate but instead projects faeces away from the nest. In March, the adults and their young return to the sea. The Adélie penguin lives on sea ice but needs ice-free land to breed. With a reduction in sea ice, populations of the Adélie penguin have dropped by 65% over the past 25 years in the
Antarctic Peninsula.

The Adélie penguin is a mid-sized bird, measuring 70–73 cm (28–29 in) in length and weighing 3.8 to 8.2 kg (8.4 to 18.1 lb). Although the sexes look the same, females have shorter wings and beaks and weigh significantly less. The adult is black on the head, throat and upper parts,

Young Adélie penguins that have no experience in social interaction may react to false cues when the penguins gather to breed.
