In birds, behaviours of nestlings and provisioning adult birds are greatly varied. In most species, jostling by senior nestlings to reduce food access of younger nestlings is common. In birds like storks where chicks are altricial, or featherless and blind at hatching, competition for food among nestlings is a common feature. The bigger and more…Continue reading Brooding over White Stork nest behaviours
Feeding in flocks is hard work. And no one knows this more than ibises. Jostling ibis flocks in marshes are common, and fights often break out as birds try to get at food before their neighbours can. Flock-feeding is not all about competition though – more eyes and ears make for a safer feeding experience.…Continue reading Touchy-feely Crested Ibis fare better amid visual egrets
The only endangered species of spoonbills is the Black-faced Spoonbill, and this species also has the most restricted distribution range of any spoonbill species. In the 1950s the population of this species was reduced to 300 in the wild. A large number of wild eggs were harvested immediately after the Korean war, which was likely…Continue reading Black-faced Spoonbills increase!!
Two new papers in the recently-completed March 2017 issue of the journal Waterbirds explore the biology and behaviour of spoonbills. Csaba Pigniczki documents a fascinating feeding behaviour of the Eurasian Spoonbill that was presented with the problem of a large frog that did not want to be swallowed. Csaba writes of how observations showed that…Continue reading Spoonbill work featured in the Mar 2017 issue of “Waterbirds”
Many Ibis species have bare heads. While it is commonly thought that this somehow helps them with keeping cool, studies to demonstrate this have been absent. Until now. Ismael Galván at the Department of Evolutionary Ecology, Doñana Biological Station in Spain, and his colleagues, decided to put this hypothesis to test. For this, they used…Continue reading Dark-coloured Ibises cannot keep a cool head! Or can they?
Eurasian Spoonbills are among the most easily identifiable bird species in the world. Their unique, spatulate bill and their sweeping method of foraging is well known to many, expert and novice alike. An equally unique group of people have come together to keep an eye on the well-being of the Eurasian Spoonbill – a widely…Continue reading The ESIEG
European LIFE+ Human Led Migration 2016. Contributed by SIS-SG member Johannes Fritz. On August 19, 2016, the human-led migration started. At 10:30 am two microlight aircrafts and 25 birds departed from the training camp in Seekirchen am Wallersee, country of Salzburg. The route leads along the Mountainranges Tennengebirge and Dachstein to the south, then along…Continue reading 25 Northern Bald Ibis start a new life!
