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.
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.
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 SouthAmerica began to appear in canals and ponds in South Florida.
They packed up in June of 2013 and headed south from San Diego with the southern tip of SouthAmerica as their destination. We hope that our journey will provide important information about many Neotropical bird species as well as inform conservation.” Very little is known about this enigmatic species.
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.
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. Perhaps the most complicated and bizarre mating system is that of the Rheas of SouthAmerica.
If you were an Eskimo Curlew (and boy, do we wish you were) somewhere in Newfoundland ready to head south across the sea to SouthAmerica, 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. Drinking and peeing through the egg shell?
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 –especially when reviewing books like A Field Guide to the Wildlife of South Georgia or Far from Land: The Mysterious Lives of Seabirds.
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.
The flocks that just a fortnight ago held multiple species in varied, if subdued, hues, now overwhelmingly consist of a single species. I hadn’t heard anything either way, but we’ve had abnormally high numbers of all three of those species moving through the area this fall.
The Andean Flamingo ( Phoenicopterus andinus ) is one of the three flamingos occurring in the high Andes of SouthAmerica. 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.
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 SouthAmerica in coastal mangroves, estuaries, coastal lagoons, river mouths, and even rice fields.
And, I started daydreaming about encountering something a little different, maybe a Horned Frog, Ceratophrys cornuta, a large, squat green and brown frog of SouthAmerica, with a wide mouth large enough to eat other frogs as well as reptiles. A book about all the frogs and toads of the world is an ambitious undertaking.
Cliff Swallows migrate to North America from their wintering grounds in SouthAmerica 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.
Though they weight less than two ounces, Least Terns migrate from SouthAmerica to the West, East, and Gulf Coast to breed on dunes or flat gravel roofs (there are also populations in the middle of the United States). In Florida, the Least Tern is a state-designated threatened species; the interior populations are federally endangered.
The island contains 80,000 breeding Sooty Terns, in addition to 4,500 breeding Brown Noddies and another 100 breeding pairs of the huge Magnificent Frigatebirds, not to mention pelicans, herons, Black Skimmers , other tern species, and so much more. Sooty Terns are incredibly birds. Trips bird banding dry tortugas Florida'
With a hardiness that belies their delicate looks (but helps explain their phenomenal success), these pioneering pigeons are already sitting on eggs at at least one location in Montana. Especially of all the species that had been introduced to the US. So right now I’m feeling pretty good about Eurasian Collared-doves.
Does the word define a species within country terms, regional terms etc? Is the term defined at the sub-species or full species level in terms of classification? The species must be listed as a separate, full species by both of the most widely used ornithological bird lists, Sibley/Monroe and Clements.
We have just three native species of lizard in New York State ( Northern Fence Lizard , Five-lined Skink and Coal Skink ) and one introduced species ( Italian Wall Lizard ). Green Iguanas range from southern Mexico and the Caribbean islands to SouthAmerica and are relatively common.
First published in 1973 in association with the Asa Wright Center, the book focuses on species descriptions, with illustrations grouped together in plates positioned in the center of the book. The guide covers 477 species, an expansion of 35 from the second edition, which was published in 1991. The AOU has not accepted that split.
At the very least appreciated for their hard-shell adaptation, the way they quietly survive in ponds, rivers, oceans, islands, forests, even, for a few species, deserts, and, if you are of a certain age, their cultural depiction as ninja warriors. Or that tortoises and terrapins are considered part of the turtle family.
Pough “with illustrations in color of every species” by Don Eckelberry, Doubleday, 1946. The National Audubon Society Birds of North America covers all species seen in mainland United States, Canada and Baja California. The press material says it covers over 800 species, so you know I had to do a count.
The text goes far beyond just those two birds, however, as Doug works his way through the puzzles presented by the incredibly wide diversity of bird behavior, even within species, citing current research and new and old theories, reasoning out the most likely and unlikely answers. The six middle chapters are my favorite reading. ” (p.
As summer ends these same birds (and the new year’s broods) then escape the snow and ice and head south for the austral summer, finding warmth, long days and abundant insect life. In the High Arctic we find several migrating species that break that mould. Anywhere from 3-8 very pale blue eggs are laid, incubated by both parents.
Like crows and jays, they are social, vocal, intelligent, and omnivorous (including eating eggs and nestlings). These are the six species that occur in Costa Rica: Yellow-throated Toucan (Ramphastos swainsonii). About the same size as a crow, this colorful creature is the largest toucan species in Costa Rica.
Ridgway himself had 23 species, 10 subspecies, and two genera of birds named for him, including Ridgway’s Hawk.) The team explored Nevada and Utah, with Ridgway collecting thousands of bird specimen, plus nests and eggs for the Smithsonian. Robert Ridgway wrote over 500 articles and 23 books, illustrating many of them himself.
Osborn, a passionate field biologist who participates to the core of her being three re-introduction projects aimed at saving three very different, endangered species: Peregrine Falcon, Hawaiian Crow (‘Alala)*, and California Condor. Sophie Osborn’s stories are personal and inspiring, but this is more than a personal memoir.
The Brown Pelican and the Peruvian Pelican are closely related and once were considered the same species. The Brown Pelican occurs in both the Pacific and Atlantic coasts of North America and northern SouthAmerica. The species reached pre-pesticide numbers by the late 1990s and was fully delisted in 2009.
In the marshes of the estancia , he discovers what he comes to believe is a new species of rail – one of the “accidentals” of the title. And the nandu, a South American rhea, has an intriguing chick-survival strategy: a week before hatching, the male (who does the incubating) pushes one egg out of the nest.
The title is a bit deceptive, for while photographs are a huge part of the book, it is grounded in the 239 species accounts written by woodpecker guru Gerard Gorman. This background material is a good, succinct framework within which to read the Species Accounts, particularly for birders new to woodpecker study.
It is from the Jan Smuts airport restaurant and offers (in two languages) chilled fruit juice, rolled oats, corn flakes, rice krispies, smoked cod, calfs liver, broiled bacon, eggs, corned beef, ham, polony, tea, toast, coffee, marmalade, jam and honey! Read about them here but also get out and experience them.
And, I looked at my eBird list and realized I’ve seen nine species of Antpitta and one of Gnateater. Antpittas and Gnateaters covers 64 species in six genera and two families. (I The Species Accounts feature highly detailed text by Harold Greeley, distribution maps, and over 250 photographs by a number of photographers.
