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.
Feeding Wild Birds in America: Culture, Commerce & Conservation by Paul J. The growth of community bird feeding programs in the 1920’s, for example, is shown to be rooted in post-World War I America prosperity–more spending money, more time, and (this is the part I like) the availability of cheap grain. And conservation.
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.
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”. Cedar Waxwings exchange berries, carry nesting material, eggs. Egg biology, from Part I. Oops, the curmudgeon in me slipped.) Peregrine Falcon nests.
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.
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!
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.
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.
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.
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 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
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.
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.
Horned Larks breed widely over North America, including up here in the High Arctic. 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. Let’s start with the altricial birds, shall we? Here are five in a nest, close to fledging.

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.
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.
Plus the fact that they only lay one egg per season which is incubated for about four weeks and the chicks don’t fledge for another fifty days gives you some notion as to why these birds are a Species of Special Concern. Photo from Wikipedia Commons taken by Terry Gray.
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.
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.
Typically there are four eggs in a brood especially on good year. Once the eggs hatch the family begins the long walk down to the shoreline. Some of these birds, breeding up here at 73 degrees north will winter at the tip of South America, Tierra Del Fuego, 54 degrees south or so. This was a later nest. “Are we there yet?
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.
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.
One of the two sub-species of Red Knot occurring in North America, the Rufa subspecies breeds in the Canadian Artic Region and migrates along the east or Atlantic coast of the United States. migration corridors from Argentina in the Southern tip of South America to Canada.
This pair first appeared four years ago, and are amongst the most northerly known breeding Pacific Loons in North America. I could see from the road there was an egg in the nest and when a Glaucous Gull began circling the nest I expected one of the pair to lift from the lake and return to defend the nest. A different Glaucous Gull.
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.
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.
” 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.
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).
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?
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.

Some of these snakes had evidence of birds in their stomachs and some were gravid with up 55 eggs nearly ready to be laid. I volunteered to help with the first python round up in 2010 when the first large African Pythons were captured. Rock Python.
Instead, they lay their eggs in other species’ nests, and let those nest-making birds (often significantly smaller than the cowbirds) raise their young. So that is a negative mark on both their records. In contrast, the Brown-headed Cowbird is a same-continent invasive species.
This happened to me recently on a birding trip, with somewhat egg-on-the-face results. Bill has led birding trips all across North America and has spoken or performed at more than 100 birding and nature festivals worldwide. I was on a birding quest trip with my friend Geoff Heeter.
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.
The White-headed Woodpecker is a non-migratory bird found in mixed coniferous forests dominated by pine trees in far western North America. White-headed Woodpeckers usually lay 4 to 5 eggs in a clutch and we’ve seen at least three different nestlings here now. References: 1 Birds of North America Online.
Now, more than ever, they are an iconic piece of the birding landscape, for David Sibley’s “ The Sibley Field Guide to to Birds of Eastern North America ,” features none other than an American Goldfinch on the cover! Unlike many other songbirds, these goldfinches subsist entirely on a vegetarian, seed-based diet.
