For example, a hypothetical National Bulbul would have no chance to get any coverage here. A paper on the species asks the important question “Does nest sanitation elicit egg rejection in an open-cup nesting cuckoo host rejecter?” ” So, either just a fake egg or a fake egg and trash (a peanut shell).
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.
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 Daurian Redstarts , personality traits (specifically, whether a bird is shy or bold) partly determine how good an individual is in rejecting cuckoo eggs in its nest. Apparently, birds that are fast in exploring new things – bold birds – are better at rejecting parasitic eggs ( source ).
A discarded pigeon’s egg reminded me that spring is just around the corner and that nest boxes should be readied in anticipation. Wrens for example might use anything that will support their nest. What’s this? Where did winter go? You don’t have to use shop-built boxes.
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. Raptors and owls are the classic examples of pellet-emitters, but there are many, many more species that are capable of that. Not a sustainable concept of development.
For example, there seems to have been dinosaurs that used feathers as their body covering. But bipedalism is a feature shared by many dinosaurs that did not fly, and counts as another example of a trait we link to birds found broadly in many dinosaurs that were bird relatives before birds ever flew.
Besides three Pioneer League championships and a bounce house for kids down the left field line, the Osprey have a vital distinction among minor league teams: the only example in pro baseball of a live mascot living simultaneously in its natural habitat and at the stadium. In a town of this size they’re a sporting Big Deal.
This is the time of year when the Pied Oystercatchers breed and already three of the sixteen pairs along this stretch of beach have successfully laid eggs. The first pair to lay eggs this season have only a few more days of sitting and then they will be very busy guarding their chicks from predators.
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. The story of Duncraft is a good example. Margaret A. The writers have created a good book.
The lengthy Introduction gives both a personal history and a global history of birds and art, including brief profiles of John James Audubon and the far lesser known Genevieve Estelle Jones, who conceived of a book eventually called Illustrations of the Nests and Eggs of Birds of Ohio in the late 19th century. Cleaning brushes, for example.
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?
Penguins are cartoons, emoticons, animated films, children’s books (though owls really take first place here), sports teams, a book publisher, and a Batman villain (a rare example of penguin negativity, though Burgess Meredith did bring an endearing attitude to his 1960’s TV portrayal).
There is something about a mature rainforest, for example, that cannot be replicated by any human. Having successfully claimed ownership of the nest, the Piratic Flycatchers move in, lay and incubate their eggs, and ultimately raise their young in the pirated nest. When out birding, I prefer completely wild habitat. Piratic Flycatcher.
.” His classes attracted diverse groups of students, often with little scientific background: “Students have to first pass biology, but most come in knowing next to nothing about birds except that they can fly, that they have feathers, and that they lay eggs.”. Examples here , here , and here.)
When we eat eggs we eat chicken eggs almost exclusively. The example of the Eurasian Collared-Dove in Florida during the late 20th century provides a model application of this rule (Population Growth and Range Expansion criteria), even though the origin of this species in the state may be in doubt. Americans love chicken.
This laughingthrush is a cooperative breeder – nestlings are fed by all members of a group, often 6-12 (not just 2 as in Wham!): “A female may share a nest with another, and 3 or more adults may take turns incubating the eggs and feeding the chicks.” ” ( source ).
A few families have a small number of eggs in the clutches, like gulls or cormorants. Others, like the petrels and some of the auks, will lay a single egg per breeding attempt. Others invest much more effort into fewer young, giving a smaller number a much better start. Seabirds are one group of birds that go for the latter strategy.
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.
Take the Wood Sandpiper above as an example. A stem of plant material with a cluster of pink Apple Snail’s eggs are marring the picture by covering part of the eye. For those who adhere to the holistic approach and who would prefer to keep the snail’s eggs on the stem, why not just move it to the side?
Maureen Eiger categorizes any unidentifiable featherless nestlings as “ Tufted Puffins ;” to Letitia Labbie, they’re “Eggs With Legs.”. Here’s an example. Upon arrival, each bird receives a chart, which is soon filled with hieroglyphics. Hit by car, HBC; caught by cat, CBC; window strike, WS.
For example, in the Delaware Bay, warming coastal waters can cause horseshoe crabs to lay their eggs earlier than normal; conversely, more intense and frequent coastal storms can cause late spawning. In both cases, knots, which feed on the crabs’ eggs, can miss their peak refueling opportunity.
Hints of potential warming in the HBW species description: “Date of first egg-laying on Honshu now 7 days earlier than it was 25 years ago” There are also quite a few Cuckoos. For example, the main article states that “At Lac de Grand Lieu, W France, birds commute 2–38 km between colony and feeding territories.”
Here’s a sad example of where logic failed. “Apparently she found a fallen American Robin ‘s egg,” she wrote, “and kept it in there for two weeks! “Five hatchling House Sparrows in a Happy Meal box,” said Johanna Walton, also in Connecticut. Obviously, there’s no air in there.” She even slept with it.”
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.
From what I read, birds are the class of Aves [feathered, winged, bipedal, warm-blooded, egg-laying and vertebrate animals]. Also, and this is pretty cool, there are extinct birds that have different characteristics [no wings, for example. Life, Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species. Who knew?].
For one thing, we become more aware of cultural biases in our science (new findings on warbling female birds, for example, reveal both gender and geographic biases). As Ackerman explains in her Introduction, studying extreme behavior brings new insight into what we think we know.
Here are a few examples: The Ostrich Communal Nesting System. Studies on improving ostrich egg hatchability. Also, I learned that in the US , ostrich eggs are priced at $40-$75. Each fresh egg weighs 4 pounds and is the equivalent of 24 chicken eggs. . Medicinal and commercial uses of ostrich products in Tanzania.
They have special adaptations to stay warm and to keep their eggs and chicks warm. Penguins are flightless, but some species locomote over long distances on antarctic ice to travel between breeding grounds and the sea.
Pileated Woodpecker, for example. For example, how does an observer actually determine if a bird is breeding in a specific area? Looking at this combination of textual and graphic data, I learned a lot about each bird in a few minutes.
As you can easily judge from the dullness of this information, it is not something I made up but rather an appalling example of nepotism in the naming of birds. Sir James McGrigor (1771-1858) Director Gen. of Army Medical Department 1815-1851.
There was no breeding behaviour evident amongst the thrushes on any of the 4 sightings over a 4-week spread from the last week of August to the last week of September, though other species were gearing up for the season, with a Southern Lapwing seen on eggs. An individual that can easily be identified could help to provide a few answers.
The smart-looking example in the photo above is by Michael Catanzariti, through Wikimedia Commons.). Scientists ponder the feasibility of genetically engineering chickens to lay the eggs of endangered bird species. So crazy it just might work?
Here is an example of one of the 36 plates, presenting Belted Kingfisher (ABA Bird of the Year!) Harrison, and Nests, Eggs, and Nestlings of North American Birds, 2nd ed. References to plate numbers (in the Plates section) and photograph numbers (in a Photo Gallery) are also placed prominently next to species name.
Or, Pygmy leaf-folding frogs, Afrixalus brachycnemis, from Tanzania, tiny climbing frogs who lay their eggs in leaves and then fold the leaves over them for protection, sealing the nest with secretions. The male and female position themselves close to each other, on top or in back, so that the eggs are fertilized as the female releases them.
Signaling theory comes up frequently in bird literature (one example I can think of off-hand is Nick Davies’ Cuckoo: Cheating by Nature, Bloomsbury, 2015), but if you’re not familiar with its basic ideas you must read the Introduction. I wish there was more discussion of research techniques and resources.
For example, why is it so hard for our family members and co-workers – many of whom have companion animals that they love – to cut cruelty from their diets and go vegan? And why do so many people say the oppose the cruel practices of factory farming, yet still eat meat, eggs and dairy products? In the author's words.
For example, it is a big, bulky bird, with a bright yellow eye and a “ patch of bare blue skin behind the eye.” When searching for a Venezuelan Troupial, look for woodland areas or open savannahs, where they search for insects, fruits, and eggs. It was introduced to Puerto Rico and other island nations, and now flourishes.
For example, the Brown Honeyeater visits more than 300 different flowers. While females hatch from larger eggs and are initially heavier than their brothers, after ten days, the male chicks weigh almost 50% more than their sisters, as they receive a higher quantity and quality of prey from their parents ( source ). ” ( source ).
For example, a government might refuse to protect - or even willfully destroy - its own natural treasure, as when, in the 1990s, Saddam Hussein's regime drained the wetlands that were home to the persecuted Marsh Arabs. In Nicaragua, the army patrols beaches to protect sea turtle eggs.
Organization within families is oriented towards user convenience rather than a strict taxonomy; for example, Ducks are divided into Resident Ducks and Migrant Ducks, Bulbuls are divided into Bulbuls and Bulbuls of the Hills and Mountains. So, we start with Megapodes (scrubfowl), Pheasants, and Partridges, then on to Ducks.
According to the HBW, when breeding, male birds do most of the incubation and parenting while females often leave the nest up to one week before the eggs hatch. According to Couzens, after laying the eggs, females sometimes immediately abandon their first mate and pair up with another male. But maybe that is actually a good thing.
They breed in dense colonies, incubate their single egg on the feet, and take more than a year to fledge a chick. The length of each bird species account varies, depending on whether the bird is native or a “visitor” (the book’s term for migrant) or vagrant, breeding or non breeding.
Did you know for example that some species of bee are cleptoparasites , exploiting the nests of other species for their own eggs. I was engaged from the very first paragraph. The preface opened my eyes to the wonderful world of bees and had me gagging for answers.
