Green-rumped Parrotlets: from egg to adult Text and photographs copyright Nick Sly (except Rae Okawa where indicated) and are used with his permission. You don’t really know a bird until you’ve studied it on its breeding grounds. She lays an egg every day or two until completing a clutch of anywhere from five to ten eggs.
It breeds across much of North America, is present year-round in the Caribbean, northern Central America, and the west coast of northern South America, and in winter is found across the rest of Central America. They are cosmopolitan, nesting even in urban areas, but also in golf courses and parking lots.
We really don’t like the presence of Black Kites along the beach when the Pied Oystercatchers are breeding. The adult Pied Oystercatcher that is sitting on the eggs will lay as flat as possible to protect the eggs. Of course Black Kites also breed and at the moment there is a nest very close to the highway.
But when spring comes and they get into high breeding plumage, wow! Big Egg Marsh in Broad Channel, Queens, hosts a wide variety of shorebirds that come to fatten up on Horseshoe Crab eggs each and every spring. When Dunlin are in breeding plumage you certainly don’t need that field mark! Amazing, no?
They generally lay four eggs, but we have only seen a maximum of three surviving chicks after a few days. A good indication that they have eggs or young is the extreme noise that they make. They will often fly at both people and other animals in defense of their eggs and young. Masked Lapwing chick hiding in a cow footprint!
Now that passerine migration has largely wound down the attention of this New York birder has shifted to seabirds, shorebirds, and the occasional trip looking for breeding birds. It is a great spot for Horseshoe Crabs to spawn and lay eggs so it is no wonder that shorebirds congregate to eat those eggs.
A breeding bird atlas is a special kind of book. For the nature lovers and birders who participate in breeding bird surveys, the atlas represents hours, often hundreds of hours, of volunteer time spent within a community of citizen scientists doing what they love, observing birds. So, what exactly does a breeding bird atlas contain?
That issue aside, SAVING THE SPOTTED OWL—ZALEA’S STORY is a detailed nonfiction picture book with a view expands from one specific owl, to Spotted Owls in general, to conservation efforts via breeding centers to save other endangered species. One of the final spreads ends with photos of Zalea, grown and with chicks of her own.
It is not quite clear why they do this as it apparently does not affect breeding success. They have written a paper on the “Feasibility of counting breeding Pied Avocets and Black-winged Stilts using drones” It seems to work, actually – though about 20 percent of breeding pairs are being missed by drone surveys.
That of course is true of many birds.) They breed on a number of basaltic lakes in southwestern Argentina, and it is not entirely clear where they all winter, but some wintering Hooded Grebes have been found outside their breeding range (and a few none-breeding birds have been found year round at two locations on the Atlantic, apparently).
Third, observing and photographing breeding birds and their young have become acts of ethical confusion as birders, photographers, and organizational representatives debate the impact of our human presence on the nesting process. And of eggs and nests and birds on nests. Cedar Waxwings exchange berries, carry nesting material, eggs.
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. According to The Birds of Africa Volume III , “In much of the tropics present throughout the year, with breeding and non-breeding birds usually indistinguishable”.
Horned Larks breed widely over North America, including up here in the High Arctic. Horned Lark fledglings seem impossibly big to me, like they are larger than the adults (which of course they are not). Here they are a common breeding bird, one of our two species that migrate from here to Europe and then south.
May is also a good time for herons and egrets, as they are in their full breeding plumage. Understandably, after all the trouble of incubating the eggs. Of course, being mean, I only show you one of them. Lesser Coucal breeds in Nanhui, coastal Shanghai. Chinese Pond Heron. Great Egret. Black-crowned Night Heron.
Traditionally since 2000 we have encountered our first Pied Oystercatcher eggs in the first week of July, but this year one pair have decided to start laying eggs early! Sadly they have already lost one clutch of eggs to predation, so by July 1st this year they are on their second clutch. Pied Oystercatcher roost.
Of course, the Red-billed Leiothrix is a species native to Sichuan – in Britain, it is now discussed whether to regard it as an invasive species ( source ). According to the McMurray hatchery , the “Silver Pheasant is considered a good ‘starter’ breed for people who want to learn more about raising pheasants” Hm.
The birds are not allowed to breed on the runway, but many loaf around on it. Around 100,000 of these terns breed on almost every available space on the island, and walking through groups of them is a deafening and quite painful experience. This species doesn’t breed on Tern Island itself, but does sometimes turn up there.
Feel free to insert your own French joke here (though of course in the US, restaurants now serve Freedom Frogs rather than French Frogs). The breeding ecology of the Yellow-bellied Warbler was actually studied exactly here at Nonggang in 2019 by 3 Chinese researchers. This included recording a total of 77,760 minutes of video.
Living in California, I am of course speaking of the Western Bluebird ( Sialia mexicana ). This entire cycle begins in early Spring when Western Bluebirds pair up for breeding. The female alone incubates the usual 4 to 6 eggs for about two weeks beginning the day the last egg is laid.
I guess the whole point about this band name is to suggest -ironically, of course – utter blandness. Breeding in Northern Japan and wintering in the Phillippines, some seem to take a migratory rest stop (and slight deviation) at the Shanghai coast. Possibly my favorite Nanhui bird this September was the Chestnut-cheeked Starling.
There were ten students in total that had signed up for the spring break “Seabirds” course in Dry Tortugas National Park, and after long drives down from North Carolina we had all made it right on time. No, that was not a typo, the Sooty Terns fly non-stop for an average of five years before they return to the Dry Tortugas to breed.
In my imagination, the job of a male Australian Brush Turkey is pretty similar – removing or adding bits and pieces to his pile of rotting vegetation in order to get the right temperature to incubate the eggs buried underneath to hatch. It breeds in tree holes, presumably explaining the more commonly used name for it.
Even though the overall breeding range remains largely unchanged from that in the 1940′s, the entire coastal population has been in recent severe decline. The ecological requirements for Black Swifts to breed restrict them to a very limited supply of nesting locations. Photo from Wikipedia Commons taken by Terry Gray.
I was there for Arts and Birding , a five-day adult course in photography, videography, sketching, painting, writing, or any combination thereof … plus lots of birding. The established courses fill up quickly, so Audubon keeps adding new ones and attracting renowned instructors. What was it like?”
At the start of this new trail we accidentally flushed a White-tailed Nightjar that was sitting on a lone pink egg. Part of the flock of Laughing Gulls , all in fresh breeding plumage. Success, further to this was a lone Brown Booby coursing low over the water. Around a bend on the trail, we came upon a clearing.
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.
Of course, I jest a bit in the above paragraph because as a sometime New Jersey birder I have birded the Delaware Bay and seen sights such as the memorable image below, in which thousands of Red Knots, Dunlins, and Short-billed Dowitchers fly up as if connected telepathically. The visual beauty and textual facts are a strong combination.
As I sit at my desk writing this post about the latest attempt at breeding for one of our pairs of Pied Oystercatchers I realise I have written 677 posts now for this website. The photo below shows the actual nest with the eggs in, but that may not be initially clear to you, so I have underlined them in a copy of the photo below.
Also from BirdLife International: In general it prefers areas where vegetation, boulders or other landscape features at ground level provide tunnels in which to shelter and to breed. Its eggs are not known, it does not migrate, and it feeds, I understand, on insects and worms.
I, of course said, “what a great idea!” The shape of the Osprey nest changes during the breeding cycle. Pairs average 59 successful copulations per clutch, starting 14 days before, and peaking a few days before, the start of egg-laying 1. Pairs copulate most often in early morning, at the same time as egg-laying 1.
According to the HBW, when breeding, male birds do most of the incubation and parenting while females often leave the nest up to one week before the eggs hatch. According to Couzens, after laying the eggs, females sometimes immediately abandon their first mate and pair up with another male. How efficient. How surprising.
While females hatch from larger eggs and are initially heavier than their brothers, after ten days, the male chicks weigh almost 50% more than their sisters, as they receive a higher quantity and quality of prey from their parents ( source ). ” The alternative for people on a limited budget is of course the Little Black Cormorant.
Unless of course you are a cuckoo and have already eliminated the competition. A female Common Cuckoo Cuculus canorus will have taken an egg from the warblers’ clutch and replaced it with her own. Be first, reach highest and call loudest, that is the road to fledging success. They must have been very proud.
Why this one city alone would be named for birds, in this country of 1,800 species, is unclear, but it could very well be a designation inspired by the nearby Islas Ballestas, an uninhabited island group just offshore from Pisco and home to enormous breeding colonies of Humboldt Penguins , Inca Terns , Peruvian Boobies , and many other species.
The species was seemingly killed off by feather hunters, but then, after years, reappeared at the site of one of the deserted breeding colonies, Torishima Island in Japan. Although we are not close nor on a direct course, the geese are skittish.
It’s when I step outside my back door, look up, and fail to spot the black scimitar shape of a Swift, coursing across the sky. However, it’s not until the end of the first week of May that the majority of the breeding birds return to our village. Both sexes incubate, with the eggs taking an average of 19 or 20 days to hatch.
The vast majority of the 10,000+ living species of birds are passerines, and the vast majority of those have a similar system of breeding: Mom and dad bird make a nest and share parental responsibilities roughly equally, if not identically. There are variations on that theme, of course. The third hypothesis was supported.
The fields near the Tiaozini mudflats look very much like a lunar landscape, but this does not seem to keep a number of species from breeding there, sometimes directly on dirt roads. But now back to birds … Little Ringed Plovers also seem to like to breed directly on the road. Blandness sells. Also available as a set of two.
One of the more interesting aspects (in my opinion) of breeding in birds is their mating strategy. In this system, females mate and lay eggs with multiple males over the course of a breeding season, leaving males to incubate the eggs and raise the chicks. of all bird species, is polyandry. 1996, Nakamura 1998).
With only 3-5 eggs per breeding attempt, it is less productive than the European Robin with its 4-7 eggs. Of course, a robin should not only be functional and useful but also appeal to the senses. While Japanese people are generally known for their work ethics, this does not quite seem to apply to the Japanese Robin.
We have been busy walking the beach and keeping an eye on our local Pied Oystercatchers and the two pairs that laid their eggs earliest for the 2018 breeding season and successfully hatched out their chicks have now lost their chicks to predation. They have only laid one egg so far and another may be laid within a day.
The male bird has the “red cap&# more than the female during the breeding season and is believed to take less interest in the nesting. Females seem to be the only sex to sit on the eggs according to literature, but no research appears to have been done on the night time routine.
The compactness of both books (Dragonflies is 208-pages and Butterflies is 224-pages long) of course stems from the small number of each type of insect in Great Britain and Ireland; comparative field guides for Europe and Great Britain are necessarily longer and heavier. I’m going to look at Britain’s Dragonflies first.
Once the egg has been laid, the female is chased away and the males hatch it.” A juvenile, if I am correct – and a rather rare bird in Shanghai, this being rather at the southern end of the wintering breeding range. Though of course, competition for these jobs from Eurasian Spoonbills is fierce.
