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.
The obvious choice was the Mallard , that plucky familiar northern hemisphere species that is the father of the even more familiar domesticated duck. In fact, as the species was quickly identified as as creating hybrids with Grey Ducks, the opinion was by the 1920s that the species shouldn’t be released further.
And of eggs and nests and birds on nests. Into the Nest , as the title says, is about the courting, mating, egg-laying, nesting, and parenting behavior of “familiar birds”. Some chapters focus on one species (Yellow Warbler), some on several related species (Chickadees and Nuthatches). And of birds courting and mating.
Crested Pigeons only lay two eggs and the nest we observed in our local park successfully hatched out two young. The Crested Pigeon would have incubated the eggs for twenty one days. The Crested Pigeon will breed at any time of year if the conditions are right.
Decades of land transformation and hydrological changes resulted in the decline of the only species of apple snail native to Florida and the kite population followed suit. While the native apple snail continued declining, another species of apple snail native to South America began to appear in canals and ponds in South Florida.
While these birds are very much liked by Chinese birders, the species could unfortunately not be named the National Bird of China as the Latin species name of the bird is Grus Japonicus. There is a great song by The Chills titled “ Complex “ Great link, right? A nice example of gender equality of sorts.
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.
But now, it’s time to go for many species. With south-westerlies they come right up to the cliffs as they make their way out towards the coast of West Africa where they will spend the winter. These gulls are back at the breeding colonies in October, even though they don’t lay eggs until April.
I spent some quality time recently with a flock of Semipalmated Sandpipers at Big Egg Marsh in my home borough of Queens, the same spot I enjoyed the company of some confiding Least Sandpipers last week. I was mostly trying to get decent flight shots of flocks of the small sandpipers whenever they flushed from feeding on Horseshoe Crab eggs.
But, for right now, we are celebrating — both Ozzie and Harriet, the pair of Ospreys that have graced the nest platform at Dunrovin since at least 2011, are back once more. Right now, the new information is coming so thick and fast that all I can do is stand amazed. Birds nests Ospreys web cams'
In California, coveys break up and pairs begin forming in February or March, followed by nest building and egg laying in May or June. She will usually lay 12 to 17 eggs, averaging five per week 1 , before beginning incubation. Occasionally, larger clutches occur due to egg dumping by other females. www.youtube.com/watch?
In late July, I travelled a half hour north of Morelia to Lake Cuitzeo (kweet-SAY-oh) to see if our two inevitable first migratory species from up north, Baird’s Sandpiper and Wilson’s Phalarope, had begun arriving. At that point, neither species was yet present, and there wasn’t much of a lake, either. So trusting.
yanked the steering wheel to the right, slammed on my brakes, grabbed my binoculars, and threw myself out of the car. A half-hour boat cruise around Eastern Egg Rock gave me a glimpse of seabird paradise, then yanked it away. There are boat trips to Eastern Egg Rock, as well as to other small islands. Soon the girls emerged.
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. Two different females among the captive group have laid eggs , and scientists are keeping a watchful eye on a few others. Now, it’s Spoon-billed Sandpipers’ turn.
Less than 1% of all species exhibit role some type of role reversal where males do what females typically do. Male Phalaropes, Jacanas, Tinamous, and Rheas build nests, incubate the eggs and take care of the chicks. Females then begin to lay eggs in the nest the male prepared. Some of the eggs will be lost to the elements.
You may be right in remarking that this is a very poor poo pic, and indeed it is. Or picture yourself as a bird fetus within an egg. Drinking and peeing through the egg shell? And it can be stored easily by the bird fetus within the egg. There are bird species that poop the white fraction and the white fraction only.
Here they are a common breeding bird, one of our two species that migrate from here to Europe and then south. I had hoped to have some Semipalmated Plover chick photos for comparison but as of last night they seem to be still at the egg stage. These ones had a head start, nesting right near the shore. With some serious legs.
Right now we’re pretty much a three species town, Ravens with a chance of Hoary Redpolls and a sprinkling of Rock Ptarmigan. (I I smashed the High Arctic Christmas Bird Count record this January 2nd by managing to find all three species here in town. Typically there are four eggs in a brood especially on good year.
As far as I can tell it is the most northern breeding record for the species. Last year the nest failed, the eggs apparently not viable, never hatching. I had crossed the stream and was approaching for a quick look to see how many eggs were in the nest this year. It would be a hard act to ignore. Splish Splash. Come and get me.
We can, of course, count wild, native, species. We can count vagrant species that made it to the area we are in under their own power. We can count introduced species that have met the criteria of the “Bird Police” for the area to which they are introduced. When we eat eggs we eat chicken eggs almost exclusively.
So, the basic idea is to show 15 species of Australian birds in each post and give you the usual trivia about them. This species has also eliminated the need for childcare – the chicks emerge from this pile on their own and never even get to see their parents. Similarly, the Grey Shrikethrush is neither a shrike nor a thrush.
Among birds the Egyptian Vulture uses rocks to crack Ostrich eggs, the New Caledonian Crow and Woodpecker Finch (one of several Darwin Finches of the Galapagos Islands), uses sticks to extract grubs from inside a branch. This is similar to the fact that all birds, even first time breeders within a species build identical nests.
I’ve been fortunate to see two Penguin species in the wild (African and Galapagos) and have dreamed of seeing more–maybe even all!–especially The goal of Around the World For Penguins is simple: Describe the 18 species of penguin and their breeding grounds “from the perspective of a traveller.”
Egg harvesting to sell as food was intensive then, with thousands taken annually from the breeding colonies in Chile. Egg collection for local consumption still continues at lower scale. Andean Flamingoes and Chilean Flamingo (far right) (Photo: Ron Knight – Flickr). Photo: Marcio Cabral de Mora – Flickr).
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?
The flocks that just a fortnight ago held multiple species in varied, if subdued, hues, now overwhelmingly consist of a single species. It’s funny, given how common Palms are at the right time of the year, that I almost never see the two populations together. It seems to me to have been a good budworm year.
This was only my fourth encounter with the species (all on the east side). He should have visited my home last month, when both species were visiting my birdbath almost daily. He should have visited my home last month, when both species were visiting my birdbath almost daily. Two other birds, both residents, surprised us.
Then, I was not sure whether this was the right thing to do. I pointed at the bird shown below but he insisted it could not be that species – no long tail … For people of a certain age, gender and background, at some point The Smiths were the most important band in the world. A happier shrike. This one looks different.
When you monitor a species of birds over many years you learn a lot from your observations and you soon become aware of the fact that some birds are just better at parenting than others. There is egg predation, chick loss and sometimes possibly just some “bad parenting”! Three eggs in the nest.
Plus a few truly difficult species. Sure, it is an introduced species in Germany. But the Kentish Plover was sheltering its young under its body, and the Little Ringed Plover was incubating an egg — right in the middle of downtown Madrid! Mandarin Ducks, Munich, Germany. But they were still Mandarin Ducks!
Life, Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species. From what I read, birds are the class of Aves [feathered, winged, bipedal, warm-blooded, egg-laying and vertebrate animals]. No surprise: there are about 10000 different species of birds in the world currently living. Because it’s important to get this right.
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.
For mankind to snatch away a species’ very existence is wrong on so many levels that I can’t begin to explain them. However, despite our best efforts to wipe them off the face of the earth, some of the more vulnerable species have managed to hang on. this species breeds. Here are some U.S. Fish and Wildlife Service.
Kind of a dull example of the species but it was still a Lark Sparrow ! I went out into Big Egg Marsh hoping for a Nelson’s Sparrow and found one, though this shot is of a Saltmarsh Sparrow. I went out into Big Egg Marsh hoping for a Nelson’s Sparrow and found one, though this shot is of a Saltmarsh Sparrow.
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).
Once you travel further north from Broome there are numerous opportunities to observe this species and any fresh water body is worth checking. Thankfully the red crest is very helpful in identifying this species. They often make a shrill sound in flight and often don’t fly very far.
Wikipedia grudgingly admits that the species “has dramatic coloration unlike any other member of its genus”. To be called Lesser Racquet-tailed Drongo – what does this do to the morale of a species? Orange-bellied Leafbird among leaves: somebody got it right naming this bird. Want to see a bird shaped like an egg?
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. Once the nest was done, she began sitting on it, preparing to lay her eggs. And, it is on this boat that I got to be a part of a great story.
I have observed this species many times (my eBird says 28 times this year alone) and never had one landing near me. Personally, I wasn’t happy, but I do not live there and do not have a septic tank in my backyard, so I felt that I have no right to complain against something that would obviously improve the lives of local inhabitants.
Large and round-headed, smartly-striped, with a gentle gaze of mysterious black eyes, in the European south of its range this species chooses preserved mountain forests, preferably mixed deciduous and conifers. Egg-laying starts in late March to early April and they remain in the vicinity till early June. Fortunately, B.
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.
If you’re a cuckoo or cowbird hoping to pawn off your parenting duties on another species, new brood parasitism research shows you’ll have better luck if the eggs you deposit in their nest are blue-green instead of brown. contemplating the pretty blue eggs are American Robins are soon to lay is a good coping strategy.).
Sedge Wren – There are records of this species in Queens, generally along the coast in fall. Great Shearwater – At this point, seabirds are my weakest family in Queens with the most species having reported in the borough that I have not seen. Western Tanager – Pretty unlikely but a guy can dream, right? 0 out of 1!).
In her free time she travels near and far to find birds to continue building her life list, though many of her favorites can still be found right in her own backyard. As we looked closer, we saw the Sooty Terns nesting right on the ground itself, calling back and forth to each other as they sat on their speckled eggs.
