Remarks to wintering Solitary Sandpipers (Tringa solitaria) in the Pantanal

EinsiedelwasserläuferDuring scientific research in the northern Pantanal between the 20th of December 2012 and the 10th of January 2013 I often observe Solitary Sandpipers along the muddy ditches on a farm. Of the two subspecies of the solitary sandpiper recognized the subspecies present probably was Tringa solitaria solitaria which usually has a more well-defined streak between the eye and the bill which are clearly visible on the images shot. On the other hand Tringa solitaria cinnamomea typically lacks these streaks, being more finely spotted and speckled instead. First I saw the Solitary Sandpiper (Tringa solitaria) on the muddy fringes of small pools, where you could see them from wooden bridges crossing these waters. There were no more but 3 individuals which you could see at one time. In between 10 days the water level rose by about half a meter. After that you only saw Solitary Sandpipers on muddy pieces of grassland between leaves of grass. These patches were characterized by highly degraded grassland, where cattle used to feed on quite recently.

The Solitary Sandpipers were never numerous and obviously preferred the open muddy shores of various types of pools. In „Birds of Brazil, The Pantanal & Cerrado of Central Brazil“ von J. Gwynne, Continue reading Remarks to wintering Solitary Sandpipers (Tringa solitaria) in the Pantanal

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
