Distinguished Author

José Vicente Barbosa du Bocage
  (1823-1907).

A Portuguese zoologist and politician. He was the curator of Zoology at the Museum of Natural History in Lisbon. His work at the Museum consisted in acquiring, describing and coordinating collections, many of which arrived from the Portuguese colonies in Africa, such as Angola, Mozambique, etc. He published more than 200 taxonomic papers on mammals, birds, and fishes. In the 1880s he became the Minister of the Navy and later the Minister for Foreign Affairs for Portugal. The zoology collection at the Lisbon Museum is called the Bocage Museum in his honor. He was responsible for identifying many new species, which he named according to the naturalist who found them.

Species of the month

Christmas Island frigatebird

Fregata andrewsi

Fregata andrewsi

Some facts about this bird:

Length: 89–100 cm (35–39 in)

Wingspan: 215 cm (7.15 ft)

Weight: 1.50 kg (3.42 lb)

Diet: The Christmas Island frigatebird is a piscivorous i.e. fish-eating bird of prey. They mostly feed on fish taken in flight from the ocean's surface (mostly Flying fish, Exocoetidae), but sometimes indulge in kleptoparasitism, harassing other birds to force them to regurgitate their food.

Range: The Christmas Island frigatebird is endemic to the Christmas Island in the Indian Ocean.

Habitat: Oceans and islands. They nest in large trees of species Celtis timorensis and Terminalia catappa which may grow to 35 metres (115 feet) tall.

Conservation status: Classified as Vulnerable (VU) on the IUCN Red List. In 2003 the total adult population was estimated to be between 3,600 and 7,200 individuals. There are only a total of 4 remaining nesting colonies in the world, all on the same island.

First described: By the Australian ornithologist Gregory Macalister Mathews in 1914.

Notable fact: This species is one of the "marathon fliers" among seabirds. In 2005, the female specimen was tagged with a satellite transmitter, and scientists were able to track a non-stop flight for 26 days. The flight went 4.000 km (2.500 mi) from Christmas Island via Sumatra, Java and Borneo, then back to Christmas Island where her cub was waiting for her. The scientists found that the bird did not make any stops during this flight, but instead fed over the sea and slept while flying.
