Well, it is that time of year again and shorebirds are breeding. Hopefully all of the migratory shorebirds that left Roebuck Bay earlier this year have been successful at breeding in the Northern Hemisphere and will soon be heading back to our shores. I have also learnt to not count my chickens before they hatch.
Chaka is a small town, with just about 2000 people. Apparently, this is another bird species that feels not so certain about flying (many humans have similar feelings). Citrine Wagtails are rare in Shanghai but apparently quite common around Chaka, though unfortunately most of the ones we saw were not in breeding plumage.
It has not been seen in its small home range in central Vietnam since around 2000. The EAZA Galliformes Taxon Advisory Group, with help from the European Conservation Breeding Group of WPA, are paving the way for this to happen by initially identifying a pure group of unrelated birds from which to breed.
Over the next few days, the Alpine Accentors ( Prunella collaris ) will arrive on their high-Alpine breeding grounds – it is time to start singing, despite that the treeless Alpine landscape is still under metres of snow. all Alpine Accetor photos digiscoped (c) Dale Forbes. all Alpine Accetor photos digiscoped (c) Dale Forbes.
Kirtland’s Warbler is a classic niche species; they breed in only very specific conditions, which occur in only a very specific area. this species breeds. Fortunately, there were still a handful of immature birds alive at sea, and a few years later they were back on Toroshima breeding again. Somebody won a Nobel Prize.
I have observed Pied Oystercatchers breeding in an area on Cable Beach since July 2000. The birds have moved the nest site slightly each year depending on human interaction, but it is still confined to one small section of grey rocky outcrops with a great view for sitting for 28 days.
The Spoon-billed Sandpiper, one of the world's most threatened birds, is rapidly heading towards extinction because young birds are being targeted for human consumption. In 2000, around 1,000 breeding pairs were known, but by 2009, the number had plummeted to just 120-220 pairs, a decline of 88%.
Kinabalu (at 13,455 feet the highest peak in southeast Asia), and human development that has resulted in freshwater rice fields, secondary forest, and oil palm plantations, this means that Borneo offers an incredibly high degree of biodiversity. The plates show differing plumages as required by the individual families and species.
Due to Prime Hook’s strategic location on the Delaware Bay, the refuge has national conservation significance as a designated RAMSAR Wetland of International Significance Site (1999), American Bird Conservancy-Important Bird Area (2000), and a Western Hemisphere Shorebird Reserve Network site (1986). www.youtube.com/watch?v=sk_5pt9OTLA.
And since the year 2000, we have an even greater bird, the… Greater Rhea ! On the contrary, the birds were quite satisfied with their new-found freedom and realms, and started breeding immediately after their escape in the spring of 2001, much to everyone’s surprise. Turns out, it wasn’t.
Whitebaters are a peculiar kiwi breed of fishermen that catch tiny migratory baitfish and then fry them up in a kind of pancake. This was at least what I was left pondering this week as read about a rogue swan attack here in New Zealand that almost left a whitebaiter dead.
Not all habitat change is due to humans; there is Chestnut Blight destroying American Chestnuts in the early 1900s, and the more recent Dutch Elm disease. The authors’ detailed delineation of problems with the accuracy of NYC breeding bird surveys or with the limits of historical writings may test a reader’s patience.
The longer Introduction lists and briefly summarizes topics covered in the Portfolio (evolution feathers, coloration, variation, senses, movement, physiology, migration, food and foraging, survival, social behavior, birds and humans, threats). copyright @2020 by David A llen Sibley. The Portfolio of Birds is comprised of 87 2-page spreads.
” California Condors are thriving now, mostly, but Osborn’s experiences in the early 2000’s were years of triumph and heartbreak. I ended up looking for photographs of Peregrine hack sites, captive breeding aviaries, Hawaii tropical forest, and the California Condors of the Grand Canyon on the Internet.
The species is listed as Vulnerable – the estimated number of individuals is 4600-5100 (HBW), of which about 2000 winter on Hokkaido. The eagles do not breed on Hokkaido, spending only a few winter months there – so if you want to see courtship displays as described in here , you have to go further North a bit later in the year.
The Grey-backed Shrike apparently prefers locations close to human settlements – not because humans are particularly nice (we are not), but “because these habitats offer a better foraging substrate and places safe from large predators” ( source ). Bad manners, I think. Difficult – no, hopeless.
Natural History is another favorite section, descriptions of behavior–how it forages for food, whether it tends to be solitary or part of a group, if the species can be trained to receive food from humans, method of movement (hopping or running), what time of day the male bird tends to sing, and more.
