Santa Cruz, Bolivia, observamos una Gaviota Reidora Leucophaeus atricilla, el primer registro en Bolivia. Adicionalmente, observamos comportamiento indicativo de anidación de la Gallareta Chica Fulica leucoptera, una especie que se consideraba como visitante no reproductiva en Bolivia, así como una Gallareta Andina Fulica ardesiaca, el primer registro para el depto. Santa Cruz. La reproducción de F. leucoptera en la laguna Guapilo fue confrmada el 5 de mayo de 2018 mediante la fotografía de un polluelo. On 28 January 2018, MLB, AEH, NLH-H and We aged the bird during the observation SKH observed several notable birds at Laguna based on the following combination of characters: Guapilo (17°46’50”S 63°05’48”W), a semi-urban uniformly dark primaries, without the white apical park 8.9 km east of Santa Cruz city centre, dpto. spots typical of older birds; a dark tail-band; Santa Cruz, Bolivia. The habitat is dominated by a extensive ash-grey neck and breast; and worn, c.35-ha lagoon, with dense mats of reeds and water brownish wing-coverts. These features are typical hyacinth Eichhornia crassipes at the edges, and of an advanced frst-year L. -

Spectacled Eiders He Spectacled Eider Is Truly a Breed Apart
WILDLIFE AND GLOBAL WARMING Navigating the Arctic Meltdown © GARY KRAMER/GARY KRAMER.NET SPECTACLED EIDERS he spectacled eider is truly a breed apart. A diving duck named for its distinctively T“spectacled” appearance, the eider spends much of the year in places so remote that its wintering grounds were only discovered in 1999, with the help of space-age satellite tracking. With its American population decimated by poisoning from ingesting lead shot, the eider was listed as a threatened species in 1993. Now global warming poses an additional peril to this unique bird, with the potential to alter both the eiders’ breeding and wintering habitats. A Rare Bird Pacific; more nutrients are flushed into the shallow seas by The spectacled eider is a medium-sized sea duck, slightly Alaska’s great river systems. These nutrients nourish algae smaller than a mallard, but with a stockier appearance. and microscopic plants called phytoplankton, which grow Males have a white back, a black breast and belly, a thick in huge numbers in the shallow waters. Algae are then orange bill and a green head, offset by large white eye eaten by tiny animals called zooplankton, which in turn patches bordered in black—the characteristic “spectacles” serve as food for larger animals.

Spur-Winged Lapwing Vanellus Spinosus
Spur-winged Lapwing Vanellus spinosus Class: Aves Order: Charadriiformes Family: Charadriidae Characteristics: Also known as the spur-winged plover (not to be confused with the recently renamed masked lapwing of Australasia), this lapwing is a wading bird identified by their striking white cheek feathers, black head cap, brown wings against a black body and long black legs. Behavior: In Africa, lapwings don’t travel far outside their home area but merely make short movements to find wetter areas of their habitats. They spend Range & Habitat: their time searching the marshy ground for small invertebrates. Marshes and wetland habitats of central Africa Reproduction: Because of their large range, these birds have variable breeding seasons. Spur-winged lapwings nest in solitary monogamous pairs, often with other mixed species bird nesting colonies. The large nesting groups help protect the birds in the colonies against predation. The lapwing pair will build a nest in a scrape on the ground sometimes lined with vegetation. The female lays 2 eggs that are yellow with brownish black mottling. They hatch after a 28-day incubation period and both sexes help feed the young. If they double-clutch, the male tends the older chicks while the female incubates the second brood (Sacramento Zoo). Lifespan: over 15 years in Diet: captivity, up to 15 years in the Wild: Invertebrates wild.

King Eiders Mated with Common Eiders in Iceland
KING EIDERS MATED WITH COMMON EIDERS IN ICELAND BY OLIN SEWALL PETTINGILL, JR. HE Common Eider (Somateriu mollissima) is one of Icelands’ most T abundant birds, with an estimated breeding population of a half million individuals (see Pettingill, 1959). Th e majority nest in colonies whose sizes range from a few pairs to many hundreds. From May 24 to 27, 1958, it was my good fortune to study and film one of the largest colonies (5,000 nests), situated on the farm of Gisli Vagnsson, along the DyrafjSrdur in Northwest Iceland. Egg-laying at this time was virtually completed, with incubation just getting under way. In my earlier paper (op. cit.) I have described the colony and pointed out that the males were present, each one stationed close to a nest while his mate sat on it. Many nests were near together-in a few cases as close as two feet, with the result that there was marked hostility among the guarding males. Presumably the males departed from the colony after the first ten days of incubation as they did on the Inner Farne (Tinbergen, 1958)) an island off the northeast coast of England. Before I visited the Vagnsson colony, Dr. Finnur Gudmundsson, Curator in the Natural History Museum at Reykjavik, told me that I should expect to find from one to several male King Eiders (S. spectabilis) mated with female Common Eiders. He had noted many mixed pairs himself in various Iceland colonies and once published an account of his observations (Gudmundsson, 1932:96-97). He went on to say that such matings are of “frequent occur- rence” in Iceland and have been known about since the 18th Century. -

A Recently Formed Crested Tern (Thalasseus Bergii) Colony on a Sandbank in Fog Bay (Northern Territory), and Associated Predation
Northern Territory Naturalist (2015) 26: 13–16 Short Note A recently formed Crested Tern (Thalasseus bergii) colony on a sandbank in Fog Bay (Northern Territory), and associated predation Christine Giuliano1,2 and Michael L. Guinea1 1 Research Institute for the Environment and Livelihoods, Charles Darwin University, Darwin, NT 0909, Australia. Email: [email protected] 2 60 Station St, Sunbury, VIC 3429, Australia. Abstract A Crested Tern colony founded on a sandbank in northern Fog Bay (Northern Territory) failed in 1996 presumably due to inexperienced nesters. Attempts to breed in the years following were equally unsuccessful until 2012 when the colony was established. In 2014, the rookery comprised at least 1500 adults plus numerous chicks. With the success and growth of the colony, the predators, White-bellied Sea Eagles and Silver Gulls, were quick to capitalise on the new prey. Changes in the species diversity and numbers of the avifauna highlight the dynamic and fragile nature of life on the sandbanks of Fog Bay. Crested Terns (Thalasseus bergii) are the predominant colonial-nesting sea birds in the Northern Territory, with at least five islands supporting colonies of more than 30 000 nesting birds each year (Chatto 2001). These colonies have appeared stable over time with smaller satellite colonies located in the vicinity of the major rookeries. Silver Gulls (Chroicocephalus novaehollandiae) and White-bellied Sea Eagles (Haliaeetus leucogaster) prey heavily on the adults and chicks (Chatto 2001). In December 1989, Guinea & Ryan (1990) documented the avifauna and turtle nesting activity on Bare Sand Island (12°32'S, 130°25'E), a 20 ha sand dune island with low shrubs and a few trees. -
