Green-rumped Parrotlets: from egg to adult Text and photographs copyright Nick Sly (except Rae Okawa where indicated) and are used with his permission. She lays an egg every day or two until completing a clutch of anywhere from five to ten eggs. Empty out the rubber boots of any nighttime invaders before pulling them on.
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.
Wood Duck ( Aix sponsa ) Female Incubating Eggs in a Nest Box “Many species of cavity-nesting birds have declined because of habitat reduction. This is the female incubating eggs in the nest box… and a couple of weeks later… then, at the ripe old age of 17 days, what’s going on out here?
My feelings about shorebirds came back to me a few days later, as I observed a mixed group of peeps and Dowitchers at Mecox Inlet, eastern Long Island, not far from where Peter Matthiessen once observed the shorebirds of Sagaponack, the stars of the first pages of his classic The Shorebirds of North America (1967). Pete Dunne and Kevin T.
It was not a kitty cat, even though all of its relatives in the Americas were. But they don’t live in North America. I find it astonishing that people argue of whether feral cats are bad for birds in North America. In North America, you’ve got Bears at the large end, Cats in the middle, and at the smaller end, the Mustilids.
Most of the Osprey breeding in North America are migratory, only Florida, the Caribbean and Baja California host non-migratory breeders 1. Osprey pairs usually form at the nest site where females are fed almost exclusively by their mates prior to egg laying behavior 1. This pair copulated several times while I was observing.
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. Native snails lay 20-50 eggs at a time during the spring. Exotic snails lay 300-500 eggs at a time, lay eggs throughout the year, and are more resistant to environmental changes.
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.
And, in South America, there is at least one species that is being heavily preyed on by North American Minks which are not supposed to be in South America. Their natural range is in a smallish region of southern South America. Which brings us to the Hooded Grebe Podiceps gallardoi.
Corey’s Best Bird of the Weekend was a surprise American Golden-Plover at Big Egg Marsh in Queens, a very good bird for the east coast in spring, as they tend to migrate north through the center of North America. How about you? What was your best bird of the weekend?
Male Phalaropes, Jacanas, Tinamous, and Rheas build nests, incubate the eggs and take care of the chicks. Perhaps the most complicated and bizarre mating system is that of the Rheas of South America. They live in flocks in the open country shrubland of Southern South America. Some of the eggs will be lost to the elements.
The Mourning Dove ( Zenaida macroura) is among the most abundant and widespread terrestrial birds endemic to North and Middle America. The nickel was placed in the nest for the photo to show me the size of the egg for identification purposes, then removed. References: 1 Birds of North America Online , 2 Droege, S.
If you were an Eskimo Curlew (and boy, do we wish you were) somewhere in Newfoundland ready to head south across the sea to South America, eating an extra bit of food before take-off will certainly be easier than going down for a quick drink of fresh water somewhere over the Atlantic. Or picture yourself as a bird fetus within an egg.
I think most of us in North America have come to the somewhat disappointing conclusion that fall migration is pretty much finished for the year. Foraging in the willows with the Palm Warblers was true-blue neotropic migrant still slumming it in North America, a Blackpoll Warbler. You’re done. Look at those bright legs!
The “Owls and Albatrosses” chapter, for example, begins with Doug’s personal experiences observing of the nesting strategies of Malleefowl and a Moluccan Megapode, Australasian “chickens who lay their eggs in unusual ways and do not parent. Why are all the real tanagers in tropical America?
They packed up in June of 2013 and headed south from San Diego with the southern tip of South America as their destination. The non-breeding distribution is virtually unknown, although they are suspected to winter in northern South America (Howell and Web 1995). Very little is known about this enigmatic species.
The featured image above shows a female incubating eggs from my first resident breeding pair back in 2007. The four to six eggs are white and unmarked. It’s not as clear as the photo of the eggs above but I did not want to disturb the female as she was circling the nest to resume her duties.
Here’s a photo of a House Finch nest before the eggs hatch and the hatchlings start producing fecal sacs. v=fHSgyxRQXvg References: 1 Birds of North America Online _ Poop Week is a week of themed posts on 10,000 Birds that cover the intersection of poop and birding, a fertile precinct if there ever was one.
Although it was formerly abundant and geographically widespread, Trumpeter Swan numbers and distribution were greatly reduced during the early fur trade and European settlement of North America (1600’s to 1800’s), when it was prized for its skins and primary feathers 1. www.youtube.com/watch?v=kq1bx7Ic2FY. v=kq1bx7Ic2FY.
However, with upcoming Easter and Passover festivities and America’s all-important Spring Break, now is a good time to focus on the peregrinations of people. As is my wont, we’ll be celebrating a secular Easter replete with colored eggs, chocolate bunnies, and a fun family hike. Where are you going this weekend?
The Bank Swallow ( Riparia riparia ) is North America’s smallest swallow. Historically, all Bank Swallow colonies in North America were found in natural sites such as banks along rivers, streams, lakes, and coasts; today, many colonies are in human-made sites like sand and gravel pits and road cuts.
The female alone incubates the usual 4 to 6 eggs for about two weeks beginning the day the last egg is laid. Here you can see two chicks have already hatched, one egg is split open with the chick ready to emerge and one egg has a hole in it pipped by the chick from the inside. i Kamakawiwo?ole’s
Photo Essay: Green-rumped Parrotlets from Egg to Adult Wednesday, 18 July An unusual auk baby. Baby Mute Swans – “immutabilis morph” Cavity Nesting Birds of North America and Their Babies!
Today, the species has all but disappeared east of the Mississippi River and has declined in western parts of its range, most likely caused by the expansion of the House Wren which destroys and removes their eggs from nest sites 1. References: 1 Birds of North America Online. This is what I am used to seeing.
Isla Rasa was declared a sanctuary in 1964, and egg-collecting and disturbance during the breeding season are discouraged. If you want to learn a lot about bird species, I find “Birds of North America Online” the best resource on the net. References: 1 Birds of North America Online , 2 BirdLife International.
The female chooses the nest site, builds the nest, lays around 10 eggs over a two week period and incubates them for about a month. References: 1 Birds of North America Online a. entrance hole. The male seldom sticks around once the female begins incubation. The young are born precocial and leave the nest within 48 hours.
Young Least Terns , some still begging for food, begin to appear on Florida beaches and will soon continue their flight south eastern South America. By early May most terns have laid eggs. There were a lot more terns incubating eggs than what we had estimated. Nesting on a rooftop is by no means safer than doing so on the beach.
The scope is worldwide; of the 24 birds depicted, five are from the Americas; five from Eurasia; three from New Zealand; two from Australasia; three from Africa; one from Africa and Asia; one from Antarctica; two worldwide, and two from Asia, introduced worldwide. of Chicago Press, 2014).
The Andean Flamingo ( Phoenicopterus andinus ) is one of the three flamingos occurring in the high Andes of South America. 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.
Green Iguanas range from southern Mexico and the Caribbean islands to South America and are relatively common. The female of the species lays ten to thirty eggs in a burrow she digs about 65 days after mating.
In North America and the Caribbean, they are found mostly in suburban, urban, and agricultural areas where grain, roost, and nest sites are available. They usually lay two eggs per clutch and most often, successive clutches will be laid while adults are still attending fledglings! This next map is data from 2007 through 2008.
They nest on large inland lakes in western North America and migrate to the Pacific coast in winter, however they maintain local populations year-round in California. They normally lay 3 to 4 eggs per clutch. Click on photos for full sized images.
The Brown Pelican occurs in both the Pacific and Atlantic coasts of North America and northern South America. They nearly disappeared from North America between the late 1950s and early 1970s because of pesticides entering the food chain. Brown Pelicans in non-breeding plumage.
Within a group, 1–7 male co-breeders compete for matings with 1–3 joint-nesting females who lay their eggs in the same nest cavity. References: 1 Birds of North America Online a. Most Acorn Woodpeckers are cooperative breeders and live in family groups of up to a dozen or more individuals.
In North America, at least in the eastern part of it, we celebrate the return of the Baltimore Oriole to parks and farms this time of year. The two dozen species are, nearly to an individual, long bodied and bicolored. Troupials raise their own chicks, generally 3 to 4 per clutch, they just steal the nest in which they raise them.
” And then I found out that bird song doesn’t just belong to the males, that there are female birds who sing too, only not so much in North America, and my mind was blown.**. They’re just like us–they talk with their hands (er, wings) and their feet and some are even crafty!” And, that’s it.
Its first flight will take it from its burrow, usually on the west coast of the United Kingdom, to the coast of South America, an extraordinary journey for an unaccompanied minor. After mating, a single egg is laid and incubation duties are shared by both parents. The gulls are able to use the sounds to locate their stumbling prey.
Saint Helena Island, situated in the south Atlantic ocean between the continents of Africa and South America, is one of the remotest inhabited islands in the world. Its numbers are declining rapidly due to feral cats and this duck is currently listed as vulnerable. Eaton’s Pintail by N. The only way to reach the island is by ship.
She will be a great fit on 10,000 Birds and I ask you all to give her a warm welcome (and feel free to ask her about those robin eggs that it seems like half of North America wants to know what to do with).
References: 1 Birds of North America Online. This is an excerpt from that report: “Because much native nesting habitat has been converted to agriculture and stored grains provide an essentially limitless food resource, tricolors have since the 1980s nested in large numbers in association with dairies.
Each chapter focuses on a specific geographic area of penguin population: (1) Antarctica, (2) South Georgia, (3) Falkland Islands, (4) South Africa and Tristan de Cunha, (5) New Zealand and Australia, (6) South America and Galapagos. Sections and subsections are denoted with the types of outline numbers I used to use in high school.
This results in all eggs and chicks being taken by the water and a failed nesting attempt. During the wet or flooded season most Amazonian shorebirds congregates on the eastern coast of South America in coastal mangroves, estuaries, coastal lagoons, river mouths, and even rice fields.

Being a westerner — raised in California, and now living in western Mexico — I was perhaps most excited about the migratory birds that breed in eastern North America. And then there was a Green Heron , not only showing us its nest, but also an egg. Then, around 4:00 p.m., And yet, there it was. But what could I do?
Cliff Swallows migrate to North America from their wintering grounds in South America to nest in large colonies, sometimes numbering in the thousands. It is illegal for any person to take, possess, transport, sell, or purchase them or their parts, such as feathers, nests, or eggs, without a permit.
