POPULATION TREND: This species has declined by well over 50 percent in recent decades and now numbers fewer than 2,000 breeding pairs. Populations have also suffered from loss of natural breeding habitat, high chick mortality due to predation by introduced mammals, and gillnet entanglement. THREATS: Yellow-eyed penguins are seriously threatened by food shortages resulting from sea-temperature changes driven by global warming. The bird's average lifespan is 23 years.įEEDING: The yellow-eyed penguin feeds primarily on red cod, opal fish, sprat, and squid. LIFE CYCLE: Males may not breed until they are three to 10 years of age, but females usually reach maturity earlier in life. Eggs are incubated for 39 to 51 days and chicks fledge at 106 to 108 days. MIGRATION: Adults are sedentary, but juveniles disperse north as far as the Cook Strait.īREEDING: Yellow-eyed penguins breed from August through March and lay eggs in shallow scrapes of leaves, grass, and twigs. RANGE: The yellow-eyed penguin is endemic to New Zealand, inhabiting the southeast coast of the South Island, Foveaux Strait, and Stewart, Auckland, and Campbell islands. The species forages over the continental shelf. Very little coastal forest remains on the east coast of the South Island, where the bird must use scrub remnants, but forest remains the dominant habitat in breeding areas on other islands. Infant jaundice is a common condition, particularly in babies born before 38 weeks gestation (preterm babies) and some breast-fed babies. Infant jaundice occurs because the babys blood contains an excess of bilirubin (bil-ih-ROO-bin), a yellow pigment of red blood cells. This article talks about the possible causes of jaundice in children and adults. Infant jaundice is yellow discoloration of a newborn babys skin and eyes. The yellow color comes from bilirubin, a byproduct of old red blood cells. HABITAT: Historical breeding habitat for this species was primarily in coastal forest and mixed-species scrub on slopes above landing areas. Jaundice is a yellow color in the skin, mucous membranes, or eyes. It has pale yellow eyes and its head is capped by yellow, with black-centered feathers bordered by a bright yellow band extending from the eye to around the back of the head. ![]() ![]() Scleral icterus is a common medical term to. Bilirubin is a yellowish pigment that your body produces when it breaks down red blood cells. Jaundice can affect newborns, children, and adults. The yellow hue is caused by an increase in bilirubin levels. Jaundice is a discoloration of the skin and eyes caused by elevated levels of a pigment called bilirubin. Different underlying medical conditions can cause the eyes to take on this color. Scleral icterus and jaundice are commonly confused because they share similar causes, symptoms, and treatment options. Scleral icterus refers to just the yellowing of the eyes and typically precedes the systemic development of jaundice throughout the body. YELLOW-EYED PENGUIN } Megadyptes antipodesĭESCRIPTION: A medium-sized penguin, the yellow-eyed penguin is between 22 and 31 inches in length and weighs 8 to 19.6 pounds. Scleral icterus describes the yellowing ( jaundice) of the eyes. While similar, jaundice and scleral icterus are two separate conditions.
