The species was in the news because some scientists had finally managed (or bothered – it’s much the same thing) to locate the population high in the mountains of the Solomon Islands, and catch and photograph one. I’m not going to rehash the arguments for scientific collecting here. Box after box of egg.
Green-rumped Parrotlets: from egg to adult Text and photographs copyright Nick Sly (except Rae Okawa where indicated) and are used with his permission. Getting intimate with a species over the course of the breeding cycle is one of the more rewarding aspects of birding, and field research too.
More than 150 bird species are known to have become extinct over the past 500 years, and many more are estimated to have been driven to extinction before they became known to science. The Gray Crowned-Crane is a new addition to the list of the world’s Endangered species, creeping up a category from Vulnerable.
[Kimball] Garrett will circulate a package in approximately the next two months to the new committee proposing to include the species on the state list. 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. punctulata.
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.
Given that according to the HBW, the species prefers dense primary and secondary montane forests, the note that the bird also forages among kitchen waste (in the same HBW entry) seems somewhat incongruous. Fish & Wildlife Service has a web page for this species – but it contains absolutely no information. ” ( source ).
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. The Guillemots pack on to the ledges, shoulder to shoulder.
It covers 403 species: 172 nonpasserine species and 231 passerine species in the Species Accounts, 198 species beautifully illustrated by the author in the Plates section. The scarcity of information on the young of some avian species is astounding.
The birdlife in the Cape is nothing short of spectacular, with a healthy dose of charismatic endemic species. Over 40 species of South African endemics can be found in the Cape – Cape Sugarbirds, Cape Rockjumpers, Orange-breasted Sunbirds to name but a few. White Sharks, especially young ones, will prey on African Penguins.
So, in order to show a few more photos of the bird than the usual two or three had I included this bird in a post of birds seen around Wolongshan, Sichuan), here is one dedicated to the species. The Latin species name is semitorques , which means something like “half-twisted” – but I have no idea why.
It is a relatively small hornbill, and not very shy – some photos below were taken on the campgrounds of Kruger Park, which more or less seem to be the species’ natural habitat by now. Also, it is the largest species of hornbill worldwide and frankly, it still is a bit miffed that it is not called Giant Hornbill.
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 Andean Flamingo is now protected under the Endangered Species Act of 1973. Photo: Marcio Cabral de Mora – Flickr).
There are 154 species of cuckoos in the world, and they’re all a fascinating bunch. It’s not a species you are likely to overlook, either, as it is extremely noisy, its cackling call carrying great distances. Give it a few more years and there’s a good chance that it will be split into a full species, just like the Cyprus Scops Owl.
BirdLife International believes that this might be maximum population the species can reach, as it seems to completely saturate its range. 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.
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.
It feels good to start a post with some truly attractive birds – such as two species of broadbills. Strangely, there do not seem to be many papers on this species. In one paper , you can find fascinating sentences such as “The new species is most similar to D. My cats refuse to even try Fiery Minivets.
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.
However, the lockdown forces me to go deeper and deeper into my photo collection, if I want to write anything at all. So, the basic idea is to show 15 species of Australian birds in each post and give you the usual trivia about them. The parrot is multicolored, providing a simple explanation for the Latin species name of varius.
Isla Rasa was declared a sanctuary in 1964, and egg-collecting and disturbance during the breeding season are discouraged. With the breeding colony concentrated on one small island this species is vulnerable to a catastrophic weather event. You know what one of my favorite things is about bird blogging?
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?
Even the Latin species name soror (“sister”) indicates the similarity to another pitta species (blue-naped). The eBird description of the Small Niltava starts with the surprisingly dull statement that “size distinguishes this species from other niltavas” Who would have thought.
We saw dozens of small, brown birds hopping in and out of the vegetation like Sickle-winged Chat , Mountain Pipit , various lark species, a Southern Bald Ibis that only a mother could love, and fewer raptors like Bearded Vultures and Cape Griffon.
Ridgway himself had 23 species, 10 subspecies, and two genera of birds named for him, including Ridgway’s Hawk.) The team explored Nevada and Utah, with Ridgway collecting thousands of bird specimen, plus nests and eggs for the Smithsonian. That’s a photo of Ridgway’s office on the right, fifth floor of the South Tower.
Do not buy these books, unless you are collecting old bird books. First published in 1973 in association with the Asa Wright Center, the book focuses on species descriptions, with illustrations grouped together in plates positioned in the center of the book. The AOU has not accepted that split. And, they are beautiful.
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! La Paz, the capital city of Baja California Sur, the southern half of the Mexican Baja, has been a real joy, with both the desired weather, and a much expanded variety of bird species. Mom on nest.
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. It’s fascinating stuff. Most of the chapters in The Bird Way focus on one or two scientists who has done extensive research on ‘outlier behavior.’
Oil begins to wash up on the beaches throughout May and June of 2010 May 6, 2010 Oil washes ashore on the Chandeleur Islands off the Louisiana coast, an important nesting and breeding area for many bird species. The babies that hatched from these eggs were released on Florida’s east coast.
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.
There are important details within that dictum that we will ignore here, but this has to do with knowing when a characteristic doesn’t really tell you about the relative position of species on a “tree of life” vs when the characteristic works for that purpose. Rather, cladistics is a way of looking at the process of evolution of species.
The most common species we see are the Stoke’s Sea Snake Astrotia stokesii , Dubois’ Sea Snake Aipysurus duboisii and the Olive Sea Snake Aipysurus laevis. 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?
For instance, I can lay my hands on data for primates and rodents (because I’ve collected those data for research) but I don’t have comparable data for bovids (just selected data) and zero data for birds (in spreadsheets on my computer). To remedy this, I visited the Animal Diversity Web site at the University of Michigan.
Osborn, a passionate field biologist who participates to the core of her being three re-introduction projects aimed at saving three very different, endangered species: Peregrine Falcon, Hawaiian Crow (‘Alala)*, and California Condor. Sophie Osborn’s stories are personal and inspiring, but this is more than a personal memoir.
She doesn’t know the species till it emerges, almost dreamlike, from the heavy glare of the sun. The Achiever’s survey voyages took place from 2005 to 2008; the goal was to collect baseline data on sea mammals and marine birds. Fox encounters 69 species, some singly, some in huge feeding or migrating flocks.
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.”. Oops, the curmudgeon in me slipped.) Peregrine Falcon nests.
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.
Pough “with illustrations in color of every species” by Don Eckelberry, Doubleday, 1946. The National Audubon Society Birds of North America covers all species seen in mainland United States, Canada and Baja California. The press material says it covers over 800 species, so you know I had to do a count.
beats have still managed to share 82 checklists and accounted for 737 species. Jamaica Bay, Big Egg Marsh. Jamaica Bay, Big Egg Marsh. Jamaica Bay, Big Egg Marsh. Jamaica Bay, Big Egg Marsh. Jamaica Bay, Big Egg Marsh. Jamaica Bay, Big Egg Marsh. Jamaica Bay, Big Egg Marsh. 01 Jun 2019.
The lack of people does not mean we have any less extinct or threatened bird species than other countries. Even the first explorers to Australia documented there was a risk of extinction of birds and animals into the future and subsequently decided to collect as many specimens as possible!
Interestingly, these juveniles look more similar to another species, the Pale-billed Parrotbill, than the adult babblers – and they sometimes are part of the same flock. If you want to see how this species builds its nest, see here.) These roads are much less of a hindrance for the Pin-striped Tit-babbler , a mid-story bird.
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. This kind of detailed genetic and developmental work has traditionally relied on model species in the lab (aka chickens).
In most years, that wouldn’t be all that special — the lake is normally where I can see the most species in a single day, so I usually go there first. These photos exaggerate the size difference between the two species, which is actually so minimal as to be almost useless for ID purposes.). Was it practicing?
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.
I couldn’t wait to give names to all my new species. I tried using the Internet, but found it frustrating for all the usual reasons; websites either didn’t include all species or were difficult to use for identification. Each species account is 2-pages long, one page of text and one page of photographs.
