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.
13 different seabird species, chief among them Common Eider and (Eurasian) Oystercatcher , stand accused of egg dumping or laying their eggs in other birds’ nests. Actually, the act seems less nefarious than oblivious since most incidents place eggs in the nests of predators!
One of my regular stops in late May and early June is Big Egg Marsh, a wonderful salt marsh just a short distance south of the much-more-famous Jamaica Bay Wildlife Refuge. 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. Eh, Semipalmated Sandpipers.
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.
Somewhat strangely, the HBW calls it a “small grey to yellow babbler” – while the species indeed has some grey parts, that is not the color that sticks to mind when seeing or remembering the bird. Plus the sibia apparently plays an important role in the pollination of one endangered rhododendron species ( source ).
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.
The Cuckoo Cuculus canorus has a bad reputation because of its habit of laying its eggs on the nests of other birds, who then raise their young. The White-rumped Swift Apus caffer , a tropical African breeding species, was only discovered breeding in Europe in the 1960s. The confusion was understandable. White-rumped Swift in flight.
Fish and Wildlife Service has listed the “Rufa” population of Red Knot ( Calidris canutus rufa ) as a threatened species under the Endangered Species Act (ESA). The other sub-species, Calidris canutus roselaari , migrates along the Pacific Coast and breeds in Alaska and the Wrangel Island in Russia. Conservation'
Besides the avian attributes of flight, feathers and laying eggs, potoos are quite possibly the most unbird-like birds in the world. This is an adaptation that it shares with other potoo species, as shown in Corey’s photo of a roosting Great Potoo. In reality though, this is actually a pretty stellar nesting strategy.
The Latin species name alphonsiana refers to Prof. 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 ). While the Buffy Laughingthrush is a nice-looking bird, its Latin species name berthemyi is quite unfortunate.
There are thousands of shorebirds that visit Broome each year and the majority of them are now in the northern hemisphere hopefully sitting on eggs. Not all of our shorebird species migrate and those that reside here are also currently sitting on eggs, or thinking about laying eggs in the upcoming weeks.
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. Apparently, birds that are fast in exploring new things – bold birds – are better at rejecting parasitic eggs ( source ).
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.
Well, not quite like clockwork, because this year one pair of Pied Oystercatchers on Cable Beach laid their first clutch of eggs a bit earlier than normal. This year the first clutch was laid at the end of May and this is the first time we have had eggs laid in May along Cable Beach since 2000. Pied Oystercatchers feeding alone.
Black-eared Cuckoos – Chrysococcyx osculans are one of the smaller Cuckoos in Australia and a Cuckoo species that I have not had much of an opportunity to photograph. Black-eared Cuckoo Black-eared Cuckoos do not raise their own young, but place an egg in another bird species nest for them to raise as their own.
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 nest was quite full once the Crested Pigeons were ready to fledge.
[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.
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 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 Cuckoos in Australia call shrilly and in a frantic descending or ascending call and often you will only hear the variety of species and not actually observe them. It was a juvenile bird and no doubt its parents had used one of the many Paperbark Flycatchers nests to lay its eggs in.
Torresian Crows Corvus orru are the most common of the Crow family in the northern part of Australia and are the most likely of the Crow species that you will encounter. In Broome it is the only Crow species and we do not have Ravens , so it makes identification easy.
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. References: 1 Baicich, Paul J.
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.
Twenty two species are distributed among six genera, depending on what happens to be extinct, and for the most part one grebe is like another. This makes Grebes vulnerable to climate change and the predation of invasive species. It is easy to see how Minks set lose in a welcoming habitat could eat an entire species.
There are no Atlantic Puffins on Hog Island; they live locally only on Eastern Egg Rock, a painstakingly-restored seabird nesting colony which hosts three species of tern (including the endangered Roseate Tern ), Eider Ducks , Black Guillemots , and more, as well as 120 pairs of puffins. There’s one!”. I wanted more birds.
The local Bald Eagles are getting busy, I suspect there is an egg in the nest. The birds were too far away to identify, and I know more than one species does this, but if I had to guess they were starlings. If half the Warblers go extinct, that would be a lot of species but you’d still pretty much have Warbler DNA.
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. Not a sustainable concept of development. Now you know what bird poop is.
The pair may have to compete for nesting cavities with several other species including native Tree Swallows and Violet-green Swallows, as well as non-native House Sparrows and European Starlings. The female alone incubates the usual 4 to 6 eggs for about two weeks beginning the day the last egg is laid.
My family took our annual post-Easter Egg hunt hike at Powder Mills Park, where I spied several gorgeous matched pairs of Wood Ducks along with lots of different woodpecker species. The month and this particular period is all the more auspicious for me and mine, as so many friends and families celebrate spring birthdays.
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.
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.
When it comes to New World flycatchers, empids tend to irritate me for the same reasons they irritate everyone, but species in the genus Contopus make me much happier for inexplicable reasons.
But now, it’s time to go for many species. These gulls are back at the breeding colonies in October, even though they don’t lay eggs until April. As the climatic conditions over the Mediterranean become stable in the summer months, the water column becomes very stratified and little nutrient and plankton gets to the surface.
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 ).
The name wasn’t proposed to settle a trans-Atlantic dispute like the previous two names, but instead merely in an effort to give this little species a suitably noble name. The name didn’t stick and the species went back to being the White Tern, but it’s a change I liked and would have been happy to see remain.
Birds hatch out of eggs, like some species of snakes, who also have no boobs, although with a snake the fact is more readily apparent. While snakes protect their eggs, and may protect their young for a short period of time after they hatch, baby snakes are very soon on their own.
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.
A discarded pigeon’s egg reminded me that spring is just around the corner and that nest boxes should be readied in anticipation. If you have room for only one nest box in your garden, target a likely species and select a suitable style of box with the appropriate entrance opening. What’s this? Where did winter go?
I remember once reaching over 130 species (a good total for a May Day in England) without having seen or heard a Jay, despite spending time in oak woodland. Not only eggs but nestling birds of many species fall prey to the Jay.” It’s a different matter in the spring.
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.
In these situations, the birds have been treated like pests and targeted for extermination, or lost their eggs and nestlings to harvesting of the fields. federal level, and a Species of Special Concern in California. (For Recently, Audubon California announced that its partnership with six California farms and the U.S.D.A.’s
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.
Award-winning free-lance science journalist Nicola Jones , most noted for her work on climate change and environmental issues, ventured into the book world with a picture book on the wildlife rehabilitation efforts for one of North America’s most endangered bird species, the Northern Spotted Owl.
Brown-headed Cowbirds evoke strong feelings in many birders, some of whom can’t abide a bird that lays its eggs in other birds’ nests, often to the detriment of the nest owners’ offspring. Now nearly ubiquitous from forests to urban centers And our young have even more bird species as mentors.
