Green-rumped Parrotlets: from egg to adult Text and photographs copyright Nick Sly (except Rae Okawa where indicated) and are used with his permission. I present here an annotated collection of photos documenting the entry of new parrotlets into this world. Empty out the rubber boots of any nighttime invaders before pulling them on.
Truth be told, I picked up this week’s beer long before we embarked on this surreal “three-hour tour” we are now collectively enduring. Collective Arts: Stranger than Fiction. The post Collective Arts: Stranger than Fiction appeared first on 10,000 Birds. Good birding and happy drinking — and be well, everyone.
We have often suspected that the Sand Goannas would steal eggs as a food source from the Pied Oystercatcher nests if they found them. The two pairs should have been close to hatching their eggs from their first clutch. The pair of Pied Oystercatchers to the north have now laid a second clutch of two more eggs.
They don’t nest until they are at least four or five years old, when they finally acquire full adult plumage, with the female laying just a single egg that takes 44 days to hatch. There were typically four teams of Climmers at Bempton, with each team taking 300-400 eggs a day.
And of eggs and nests and birds on nests. In the all too brief introduction to the book, they state, “This book aims to shed light on the family lives of birds, a topic that has captured our collective imagination and enriched our language despite being shrouded in mystery.”. Egg biology, from Part I. Peregrine Falcon nests.
Observers have noted these colorful crows flying up to 18km to and fro from an old oakwood when collecting acorns. They are normally shy and relatively secretive woodland birds, but at this time of the year when they are in full acorn-collecting mode, they become much bolder and more conspicuous. It’s a different matter in the spring.
The two have built up a devoted following through years of triumph – like last season, when they fledged three young – and tragedy – like the season before, when their eggs didn’t even hatch. Ozzie and Harriet with the 2013 brood.
The text is divided, not taxonomically or chronologically, but with a weirdly visual bent – one section is devoted to what birders do, while roughly twice as many pages go to matters like decorating with a bird theme or collecting bird memorabilia and art. As I read, I realized that I had encountered books very much like this before.
The use of eBird data is interesting and it shows just how valuable the collected reports of birders can be in figuring out the status and distribution of species. Just as interesting is the nugget that Pin-tailed Whydah , an introduced species itself, has adapted to using Nutmeg Mannikins as a host for its eggs.
It didn’t occur to me till I started reading The Falcon Thief: A True Tale of Adventure, Treachery, and the Hunt for the Perfect Bird that there was also a possible threat to the eagle herself: poachers, who steal raptor eggs and chicks. McWilliam realizes he’s dealing someone special, a career falcon egg-thief.
The early threats of guano harvesting and eggcollecting have been replaced by the more ominous threats of oil pollution and overfishing of their favorite food source – pilchards. On the mainland they face predation from domestic cats, dogs, genets, mongoose and Cape Gulls which steal their chicks and eggs.
We continue to have egg predation at many of the nest sites and chick loss, but one pair of Pied Oystercatchers is being successful in raising two chicks so far. There has never been two eggs hatch and two chicks survive for more than about ten days since we started to keep an eye on them in 2000.
Next is the already noted “Illustrated Glossary” is a unique collection of photographs and drawings illustrating scientific terms for parts of the mouth and beak; bones of the leg, feet, and wings; feather tracts; feather development; as well as the standard bird topography diagrams.
This laughingthrush is a cooperative breeder – nestlings are fed by all members of a group, often 6-12 (not just 2 as in Wham!): “A female may share a nest with another, and 3 or more adults may take turns incubating the eggs and feeding the chicks.” ” ( source ).
Egg harvesting to sell as food was intensive then, with thousands taken annually from the breeding colonies in Chile. Eggcollection for local consumption still continues at lower scale. The initial decline in the Andean Flamingo’s population appears to have started as early as the mid 20th Century.
Some lingered to gaze at samples from the Field’s collection of bird specimens, such as perfectly preserved thrushes, warblers, and even a Rose-breasted Grosbeak under glass. Other hardy souls signed up for an early morning “Ostrich Run” 5k, with the prizes beinging–you guessed it–actual ostrich eggs.
They may be about bird eggs ( The Most Perfect Thing: The Inside (and Outside) of a Bird’s Egg , 2016), or a 17th-century ornithologist ( Virtuoso by Nature: The Scientific Worlds of Francis Willughby, 2016), or How Bullfinches learn songs from humans ( The Wisdom of Birds: An Illustrated History of Ornithology.
With populations plunging dramatically over the last decade, researchers from the Wildfowl and Wetlands Trust, Birds Russia, and a number of other conservation organizations made the always-controversial call to pluck eggs from the imperiled wild population and establish a captive breeding program as a final hedge against extinction.
Last year not a single chick survived and there is much predation of both eggs and young birds along the length of beach. The first pair of Pied Oystercatchers to lay eggs this year was the same as last year. The first egg laid is not necessarily the first to hatch and often there is a day in between when they hatch.
After 28 days of sharing the duty of sitting on three eggs we finally had the arrival of our first Pied Oystercatcher chicks for 2012 on Friday August 3rd. It is unusual for three eggs to be laid here in Broome and many eggs do not even hatch due to predation each season.
Unlike the Common Cuckoo, the young GSC doesn’t eject its foster parents’ eggs or chicks from the nest, but is reared alongside them. A Jay of the endemic Cypriot race glaszneri It was in the Botanical Gardens, too, that I watched Red-rumped Swallows collecting mud for their nests ( below ).
The Red List category is justified as follows: “This poorly known species qualifies as Critically Endangered because it is estimated to have a tiny population, which is in decline owing to egg-collection, disturbance and the loss of coastal wetlands” So it was quite exciting to see 3 of them at Nanhui, Shanghai – two adults and one (..)
Barnacles are attractive geese that have long been popular in wildfowl collections According to the Atlas , the combined population for the Russian, Baltic, Netherlands population is around 770,000 individuals, which is an awful lot of geese. A pair did lay infertile eggs in Iceland in 2018, but that’s about the only record I can find).
Isla Rasa was declared a sanctuary in 1964, and egg-collecting and disturbance during the breeding season are discouraged. Heermann’s Gulls form large breeding colonies on arid islands in the Gulf of California, Mexico, from March through July.
As a Northeast birder I am familiar with the alarming decrease in the number of Red Knots along Atlantic shores and have signed petitions and written e-mails calling for legislation and rules that will limit the overharvesting of the horseshoe crab, whose eggs Red Knots depend on. million in the late 1990’s. Should the gulls be controlled?
Data collection for the Second Breeding Bird Atlas Project of Pennsylvania took place from 2004 through 2009, roughly twenty years after the first official atlas project, 1983 through 1989. It was a gigantic, innovative project that collected and catalogued massive amounts of data about birds, habitat, and ecological change.
We had a nice collection of birds of prey for the day. In spite of our proximity, it spent a good while positioned as if it had eggs there. But this photo is just good enough to show a total lack of white on the bird’s rump, confirming that it, and all its companions, were Tree Swallows rather than Violet-green Swallows.
Occasionally the Tristan Thrush Nesocichla eremita will prey upon chicks from the two-egg nest of the Inaccessible Island Rail but this not enough in any way to threaten the species. So desirable was it, however, to find out what this flightless rail was like that he left collecting material with the late Rev.
Once upon a time, people and especially children felt free to interact with wild birds in any way that would satisfy their curiousity — watching and learning, yes, but also harassing and chasing, collectingeggs and nests, stealing nestlings as “pets”, and killing birds for amateur taxidermy efforts.
En route they will be “birding in nearly every country in mainland North and South America,” and, as they say on their excellent blog , “Our journey is about collecting valuable data on bird species, their status and distribution, current conservation issues, and more along the way.
Peripatetic ornithologist Nick Sly has long been a friend of the blog here and has contributed such classics as Green-rumped Parrotlets from Egg to Adult and Forpus passerinus and the Ornithologists of Masaguaral. Please read and then vote for either Nick or Maria’s research!
Rock Hyrax Stuart provided a wonderful field lunch alongside a stream with samosas, a field-standard hard-boiled egg, and other snacks. We did not make too many other stops other than to head back to the “Highest Bar in Africa” for a celebratory beer and I was able to add to my foreign currency collection with a $20 Lesotho Loti.
However, the lockdown forces me to go deeper and deeper into my photo collection, if I want to write anything at all. It has been more than 5 years since I last went to Australia, and I was even less of a qualified bird photographer then than I am now. And that seems to be the only vaguely satisfying thing left to do at the moment.
There is a lot of extreme behavior here (and a lot of that behavior takes place in Australia), but this is not simply a collection of the world’s most fantastic bird tales.
After collecting nearly 70K bird photos, he felt that it was time to share them, so he now has his bird blog in order to do just that! Once the nest was done, she began sitting on it, preparing to lay her eggs. They’ve been traveling the world ever since!
If we had been predators, their actions would have (hopefully) led us away from the nest, keeping their eggs and chicks safe. Next to it lay an egg, the baby inside fervently pecking and tapping until it too could break the shell and emerge onto the dunes. While not as adorable as chicks, I still love to see bird eggs!
The Indochinese Green Magpie is one of four species of green magpie (it used to be only three, but one of the subspecies collected enough frequent flier miles to get an upgrade to full species). Altruism, fortunately not of the Sam Bankman-Fried variety, though probably not very effective either.
If there’s one common theme to this week’s bird news items, it’s their collective bizarreness: The eagle has landed—on the drone, as France trains birds to take out drones that stray into restricted airspace. Scientists ponder the feasibility of genetically engineering chickens to lay the eggs of endangered bird species.
A schoolboy eggcollection and a house near the sea, as well as a childhood that allowed me to become acquainted with almost every nook and cranny for 4km in any direction. was perhaps no different to many of my peers.
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? These do lay eggs on land and are (reasonably) mobile once they hit the beach. It seems like there is great diversity in this continent.
Breeding is well underway and everywhere you look the Glaucous Gulls are, ahem, engaged or collecting grasses and sedges for nests. Friends of mine came home from those lakes with tales of Sandhill Cranes , Snowy Owls with eggs in the nest and others.

I enjoy collecting children’s books about birds and nature that I come across in the expected (book stores) and unexpected (academic library conference reports) places. Here are three excellent but very different children’s books I enjoyed this year (two were published in 2013, one in 2011). Other Europeans came.
To make a great omelet you've just gotta break eggs. The fishing is best where the fewest go and the collective insecurity of the world makes it easy for people to hit home runs while everyone is aiming for base hits.” – Tim Ferriss. So what are you afraid of most? Is it your success? Ruffling feathers? An Experiment.
