Fall bird migration and waterfowl in southwestern USA – August 2013

In late summer (mid-late August/early September), the Brehm Fund for International Bird Conservation, Bonn, offers an ornithological tour to the United States. The southwestern part – located between the Pacific Ocean and the Gulf of Mexico – provides numerous ornithological highlights, which we will do in California and Texas Station.

California, because of its exposed location along the Pacific flyway, has an extremely diverse avifauna (over 640 species), including interesting deposits of water-and seabirds. In addition, up to 10 different species of hummingbirds, such as Anna’s, Costa’s and Calliope Hummingbird, can be observed regularly. Highlights of the trip will detour to the coastal marshes south of Los Angeles (e.g. Western Sandpiper, Belding’s Savannah Sparrow), the lagoon of Malibu (Least Tern, Black Skimmer) and in the vicinity of the Salton Sea (Caspian Tern, Yellow-footed Gull). We will also check typical chaparral habitats (coastal shrub with endemic Wrentit, California Quail, Black-headed and California Gnatcatcher) and visit the coastal mountain range with its coniferous forests (occurrence of Acorn Woodpecker, Mountain Bluebird, Steller’s Jay). The trip to a bird island of Channel Islands National Park (including endemic Island Scrub-Jay, colonies of Brandt’s Cormorant and California Gull and the possibility of observing whales) can be scheduled optional. In 2009 and 2011 excellent images of pelagic birds could be shot to enlarge the portfolio von Bird-Lens. With a bit of luck these seabirds – as you see here in the gallery– can be seen on the ferry Continue reading Fall bird migration and waterfowl in southwestern USA – August 2013

Pelagic Birds in the Western Palearctic

Pelagic or oceanic birds, seabirds or marine birds all describe bird which spend a significant portion of its life on the open ocean, rarely venturing to land except to breed. Their flight is often described as elegant and beautiful. This is particulary true for the Black-browed Albatross (Thalassarche melanophris), as you can see on the image on the right. Pelagic Birds are powerful fliers that can remain for hours while gliding or soaring over the waves. When the birds rest, they do so by swimming quite high (floating) on the water. Pelagic birds may be found hundreds or thousands of miles offshore. Pelagic birds typically feed on fish, squid and crustaceans as well as offal from fishing ships or trash dumped into the ocean. Although “Pelagic Birds” does not have a scientific meaning in it´s strict sense, normally you mean albatrosses, shearwaters and petrels are described as being pelagic. The right taxonomic description for these birds are “Procellariformes”. There are lots of pelagic bird species with a great range of sizes and ranges. In the Gallery you will find different types Continue reading Pelagic Birds in the Western Palearctic
