For one species of seabird in the Galápagos, the child abuse "cycle of violence" found in humans plays out in the wild. The new study of Nazca boobies by Wake Forest University researchers provides the first evidence from the animal world showing those who are abused when they are young often grow up to be abusers. The study appears in the October issue of the ornithology journal, The Auk. "We were surprised by the intense interest that many adults show in unrelated young,...

Until now, the scientific community had assumed that wild animals died before they got old. Now, a Spanish-Mexican research team has for the first time demonstrated ageing in a population of wild birds (Sula nebouxii) in terms of their ability to live and reproduce. "It was always thought that senescence was something particular to humans and domestic animals, because we have an extended life expectancy", Alberto Velando, lead author of the study and a researcher at the Ecology and Animal...

This is the fifth in a series of columns on my trip to the Gal pagos Islands with KFI's Bill Handel and 100 of his friends and fans. We were getting into the routine - 6:30 a.m., time to rise and shine. After the previous day's outing, when we all saw our first blue-footed boobies and marine iguanas, the group was raring to go. Again, we broke into groups of 16 (the number of people on a zodiac) with the "kids" going first and the "not-so-fast-walkers" bringing up the rear. This...

If you ever felt at least metaphorically like you wanted to kill your brother or sister, your sibling is lucky you're not a booby. A Nazca booby, a Galápagos Island seabird, is eager and able to kill a sibling in the nest. A new study links the murderous behavior to high levels of testosterone and other male hormones found in the hatchlings. The elevated levels of male hormones, called androgens, increase aggression in both male and female chicks and prepare the birds...

The Nazca booby, a Galápagos Island seabird, emerges from its shell ready to kill its brother or sister. Wake Forest University biologists and their colleagues have linked the murderous behavior to high levels of testosterone and other male hormones found in the hatchlings. The study appears in the June 18 edition of the online journal PLoS ONE. The elevated levels of male hormones, called androgens, increase aggression in both male and female chicks and prepare the birds to fight to the...

The Blue-footed Booby (Sula nebouxii), is a seabird found along tropical and subtropical islands off the Pacific Ocean. Its most famous colony is on the Galápagos Islands, Ecuador. They also occur along the coast of California, USA. These specimens are strictly marine birds. Their only need for land is to breed, which is done along rocky coasts. This bird is quite abundant in concentrated areas and is not threatened or endangered. The Blue-footed Booby is about 32 inches in length and...

The Nazca Booby (Sula granti), is a species of booby found in the eastern Pacific ocean, mainly on the Galápagos Islands and Clipperton Island. The northernmost limit of its breeding range is Baja California where it can also be spotted on the Revillagigedo Islands. Once regarded as a subspecies of the masked Booby, it is now recognized as a separate species. Nazca boobies are known for practicing habitual siblicide. They lay two eggs, several days apart. If both eggs hatch, the elder...

The masked Booby (Sula dactylatra), is a large seabird of the gannet family, Sulidae. This is a bird of tropical waters and breeds on islands in all tropical oceans except the eastern Atlantic. This is a fairly sedentary bird that winters at sea and is rarely seen far from its breeding grounds. Some Caribbean birds wander north to warm southern Gulf Stream waters off the eastern seaboard of the United States. It is the largest booby, attaining 32 to 36 inches in length with a 60 inch...
