There are Little Terns that breed across the north of Australia, Little Terns that breed on the coast of eastern and south-eastern Australia and another population that visit at this time of year from Asia. The population of Little Tern that visit from Asiabreed in Asia and visit Australia in their non-breeding months.
It’s a bang-up breeding year for super-endangered birds! The species, which migrates from the Russian Arctic to Southeast Asia, is down to about 200 breeding pairs in the wild, due to habitat loss and poaching. For the past several years, getting the birds to breed has been an exercise in futility.
I’d really like to see a Coral-billed Ground Cuckoo (South-East Asia), while to see any of the Madagascan couas would be pretty cool (there’s 11 of them). Perhaps the most curious thing about the Great Spotted Cuckoo is its distribution, for it is both a non-breeding Palearctic migrant to Africa, and a trans-Africa migrant.
Most readers here will be familiar with the plight of the Spoon-billed Sandpiper , a critically endangered wader that nests on the Russian tundra and winters in Southeast Asia. One of the great difficulties with a captive breeding program is how to avoid making things worse. Also, there’s a bear!)
The breeding season is longer, starts earlier. But, getting the nest set up, amorous acitivites, the laying and hatching of the egg, all that, happens earlier. “Many long-distance migrants arrive so late on the breeding grounds that they have little opportunity to respond to warming conditions by nesting earlier.”
The HBW even mentions the importance of Ruoergai for this species: “Key sites for migrants include the Ruoergai Plateau (China), which is also an important breeding area” Common Mergansers also seem to use these wetlands as breeding area. Understated elegance is also something the White-browed Tit is rather good at.
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. Borneo, the authors say, is under-birded. I think we need to do something about that.
Europe has one species (Eurasian Spoonbill), the Americas have one (Roseate Spoonbill), Australia two (Royal and Yellow-billed Spoonbill), and Asia has two as well (Eurasian and Black-faced Spoonbill). Studies on improving ostrich egg hatchability. Ostriches originated in Asia. Ostrich industry in Egypt. and the very topical.
She also monitors Pied Oystercatchers breeding along a 23km stretch of beach by bicycle and on foot. Speaking of pregnant snakes, do sea snakes lay their eggs ashore like sea turtles or do they keep them internally until the young are ready to hatch/ be born, like some sharks? It seems like there is great diversity in this continent.
I do not get too many comments on my blog posts, but it seems that whenever I write about jacanas – whether in Africa, Australia, or Asia – there is an unusually high number of reactions (well, maybe one or two rather than the usual zero) from female readers. This is ok as birds do not have teeth anyway). How efficient.
A female Common Cuckoo Cuculus canorus will have taken an egg from the warblers’ clutch and replaced it with her own. But when a dragonfly was offered, everything went quiet (for all you oders, it was a Blue Dasher Brachydiplex chalybea, a libellulidae common across much of Asia. Slightly tangy, I’m told ).
However, it’s not until the end of the first week of May that the majority of the breeding birds return to our village. The first eggs are usually laid at the end of May or sometimes in the first week of June, but this can vary depending on the weather. Both sexes incubate, with the eggs taking an average of 19 or 20 days to hatch.
Research required to determine its feeding ecology and breeding biology.” ” “Breeding Mar–Jun. Habitat: Range and Distribution : Sunbirds : Found across Africa, the Middle East, and parts of Southeast Asia, inhabiting a variety of environments including forests, savannas, gardens, and shrublands.
They breed from July to March in Southern Australia and from September to June in the north. They often call with a whooping bugle trumpet sound in flight and the sound is similar to a Channel-billed Cuckoo , which are returning to the Broome area from Asia to breed.
Of course, it is hard to resist looking at a paper titled “Host personality predicts cuckoo egg rejection in Daurian redstarts” Basically, the personality of a female redstart (bold or shy) predicts the responses to parasitic eggs – bold hosts are more likely to reject parasitic eggs.
This population’s breeding range is covers much of the Eastern Arctic, from northern Labrador up to Ellesmere, in as far west as the Kivaliq region (Rankin Inlet, Arviat). The population that nests in the western reaches of North America’s Arctic will cover about twice that distance, through Asia and down in to Africa.
We have seen them on remote beaches hunting shorebirds and taking their eggs and they have been responsible for much of the egg loss in breeding Pied Oystercatchers along the Broome coast. Feral cat predation on Pied Oystercatcher eggs. They are incredibly cunning and not easily trapped. Rock Doves in Broome.
Around this time of the year, the first few waders are back in Shanghai from their breeding grounds far further up north. Generally, being back here early is not a very good sign – it may indicate a failed breeding attempt, as suggested for Asian Dowitchers in a paper on their presence in Lianyungang somewhat further north of Shanghai.
The Bar-backed Partridge is a species of partridge found in southwestern China and Southeast Asia. Another, somewhat more interesting study suggests that nest sanitation (ornithologists speak for cleaning up your room) helps Common Tailorbirds to recognize and eject parasitic eggs.
Indeed, most cuckoo eggs are accepted by the babax ( source ), although a small proportion of hosts reject cuckoo eggs and often boast about this capability when having a few too many drinks. He spent the years from 1836 to 1858 in Asia, first in Indonesia, then in China, partly as the consul of the city of Hamburg in China.
What the Owl Knows is organized into nine chapters: introduction, adaptation (including vision and flight), research and researchers, vocalization, courtship and breeding, roosting and migration, cognition, and two chapters on owls and humans–captive owls (not zoos, educational owls) and owls in our cultural history.
.” It is a relief to eventually reach the chapter on The Life of Waterfowl, written in a much more conversational style and unashamedly fascinated with waterfowl’s unique breeding behaviors. Barker and Carrol L. Harrison, 2005, PUP).
A paper titled “Crested Goshawk Accipiter trivirgatus may adapt well to life in urban areas across its range in Asia” already made the same observation in 2018. Apparently, after a male first mates with a female, he throws out the first one or two eggs she lays in their nest. Black-naped Orioles are breeding in Fengxian.
