The strategy of this pair of Pied Oystercatchers is to lay their eggs in a dune area which is amongst the busiest area for vehicles on the beach. There are numerous species of raptors around Broome including Black Kites and Whistling Kites. Meanwhile, the other pairs of Pied Oystercatchers along Cable Beach have begun to breed as well.
Hence, back to strategy. Other species of interest include the southernmost breeding population of Greylag Goose in Europe, Goosander (at bigger and deeper Megali Prespa), Hazel Grouse (at Mt. The local bird list is impressive at 273 species and my September daily averages were around 50 bird species.
This large flock is generally the non-breeding birds and on one occasion we have observed a nest there, but we do not know the outcome of it. In recent years there have been Pied Oystercatchers attempting to breed along the shores of Roebuck Bay. Many of the migratory shorebirds still have some of their breeding plumage.
This year we have continued to monitor the breeding of several pairs of Pied Oystercatchers along the coast in Broome from Gantheaume Point to Willie Creek on the south side. This species are long living and so the population appears to be sustainable at this stage despite the predation. Pied Oystercatcher family searching for food.
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.
I was happy to read that the wood stork ( Mycteria Americana ), a bird near and dear to me, was down-sited from the status of endangered to threatened species. Fish and Wildlife Service is down-listing the wood stork from endangered to threatened under the Endangered Species Act (ESA). However, birds in the U.S. Photo: U.S.
Its population actually fluctuates in response to the availability of Spruce Budworm and though it nests on the ground it is entirely inseparable from the forests of the north during breeding season. Even more surprising is that Tennessee Warblers often molt and migrate simultaneously, a strategy that few other birds take advantage of.
The species that manage to colonize these islands evolve in competition with relatively few other species, developing survival strategies based on interdependence, co-evolution, and mutualism rather than adapting to deal with a broad range of predators and competitors. A species, wiped off the earth, never to exist again.
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 The goal of Around the World For Penguins is simple: Describe the 18 species of penguin and their breeding grounds “from the perspective of a traveller.”
This seems like a strange – but welcome – turn of events after having failed to see this species several times in the region. It initially ran off, but then adopted a different strategy by crouching on the ground and relying on its camouflage, its big eyes looking up at me.
Starvation and predators make it hard to grow up, and birds have evolved a lot of strategies to give (at least some of) their chicks the best chance in life. One strategy that varies among birds (and other animals) is the number of offspring. Seabirds are one group of birds that go for the latter strategy.
It is one of three species of ani ( Groove-billed and Greater Anis are the other two) and together form a unique branch in the cuckoo family. In addition to having a communal nesting strategy, anis also spend a significant amount of time allopreening, huddling together, and sunning themselves together on exposed branches.
Counting the Birds I was in my teens when I undertook my first bird-survey: it was field work for the British Trust for Ornithology’s The Atlas of Breeding Birds in Britain and Ireland. The breeding and wintering birds of Britain and Ireland. Published in 1976, The Atlas was, I believe, the very first work of its kind.
However, there are those species which have a hard time bringing attention to themselves such as Yellow-shouldered Blackbird , Giant Nuthatch , and Vinaceous-breasted Parrot. Regardless of their popularity, these species and the threatened ecosystems they inhabit are equally spectacular. Curassows are such stately birds.
In China, wherever there is one real tourist attraction (like the Great Wall), the local strategy seems to be to add some fake attractions – replicas of palaces or tombs, amusement parks, shopping centers – in order to maximize the income from tourists. But the starting point has to be a real attraction, not a fake one.
Predators that rely on lemmings, like the Snowy Owl , took advantage of the bounty and had great breeding success, raising large broods which, after the lemming population crashes, dispersed far and wide. And while I haven’t made it over their yet I hope to before they disperse into breeding territories. I’m a messy eater.
It has recently been reclassified as Critically Endangered on the IUCN Red List; this category is reserved for only the most threatened species in the world. If this bird did become extinct, it would be the first pheasant species to have been lost in the 400 years since proper records began.
Over the next few days, the Alpine Accentors ( Prunella collaris ) will arrive on their high-Alpine breeding grounds – it is time to start singing, despite that the treeless Alpine landscape is still under metres of snow. all Alpine Accetor photos digiscoped (c) Dale Forbes. all Alpine Accetor photos digiscoped (c) Dale Forbes.
Both the male and female of the species have a bright red crown. Groups may also contain up to 10 male and female non-breeding helpers, usually offspring of the group produced in prior years 1. Acorn Woodpeckers are the only species to store individual nuts in holes drilled in granaries. Click on photos for full sized images.
It is interesting to see the different evolutionary strategies of closely related bird species – the various snow-white egrets with their “I don`t give a damn who can see me” attitude contrasting with the ridiculously well-camouflaged yellow bitterns. So, here are some of the species living in Nanhui, Shanghai.
They are two strikingly different strategies, both of which seem to working well this spring, as everywhere one turns there is new life on the Tundra. Horned Larks breed widely over North America, including up here in the High Arctic. They are fed by one or both parents, even after they’ve fledged and left the nest.
With my recent relocation to the central forests of Trinidad, I have been afforded the incredible opportunity of observing three oft-confused species in close proximity to one another. In reality these species are rarely in the same place at the same time, however! All the more reason to keep birding!
Avocets, Black-necked Stilts , and Spotted Sandpipers breed at the Henderson Bird Viewing Preserve. Well, they weren’t so much of a flock as they were a group of birds all following their own foraging strategy in the same area. Later in the season more species show up. No, make that two Lucy’s Warblers !
Though these plovers are common on the North Norfolk coast, their nearest breeding grounds are far to the north. A few do breed in Europe, on the extreme north-east of European Russia. Both species of geese have increased hugely in recent years. Pinkfooted Geese.
Though Ron is based in Ontario his reports are eagerly anticipated by birders across the northeastern United States and eastern Canada because it takes into account a vast array of data to figure out which irruptive species might show up where. See individual species forecasts for details.
The Brown Pelican and the Peruvian Pelican are closely related and once were considered the same species. Brown Pelicans in non-breeding plumage. Both are the only Pelican in their non-overlapping breeding grounds. Peruvian Pelican in non-breeding plumage. Brown Pelican in Breeding Plumage.
In the pelagic ‘deserts’ of Florida, as in deserts on land, specialist bird species manage to carve out an existence. This species also has a noticeably stronger and direct flight pattern, which can be very helpful when identifying individuals from a distance on a boat.
As bad as a cold, wet, and windy Memorial Day Weekend is for people it is even worse for birds, especially species that rely upon flying insects for sustenance. Strong wind and lots of rain has only added to the misery. It’s a horrible picture of a Cliff Swallow , but this one of two that were foraging with the flock.
With all of those birds singing and showing off their breeding colors, it’s no surprise that we see major bird races like Champions of the Flyway and The World Series of Birding , along with other main birding events like the Global Big Day. They got all three potoo species in Costa Rica.
The highly specialized foraging strategy of flamingos makes them vulnerable to the effect of subtle changes in habitat quality. Egg harvesting to sell as food was intensive then, with thousands taken annually from the breeding colonies in Chile. The Andean Flamingo is now protected under the Endangered Species Act of 1973.
When you monitor a species of birds over many years you learn a lot from your observations and you soon become aware of the fact that some birds are just better at parenting than others. Each pair has a strategy and sometimes it is successful and sometimes it is not. There was one mystery-where had the pair from Gantheaume Point gone?
Finally in 1799, the first visitors on this volcanic land were a group of French seal hunters who were after the fur seals that can be found hauled out on the beaches for fur and oil, which almost wiped out the local population of the species. About half of all breeding Wandering Albatross nest on the Prince Edward Islands.
A lovely looking and distinctive sounding bird (so they say, I sadly have not seen one…yet), the Kirtland’s Warbler can only be found during its breeding season in Jack Pine forests 5 to 20 years old in the northern Lower Peninsula of Michigan. Fish and Wildlife Service endangered species list.
That is hardly a surprise: this area holds 3 to 4 breeding pairs of White-tailed Eagles, which represents the biggest density per square mile anywhere in the country! Annex II of the Bern Convention lists 45 of Beljarica’s bird species, with a further 91 species in Annex III.
192) from the timing of seasons to the ferocity of weather to the shape of breeding, wintering, and stopover habitat to even the size of birds themselves. Climate change looms large over all migration research, it “is reshaping every single thing about migration” (p. It is often hard to be positive.
Illustrated by Chandler’s mainly excellent photos, the book shows about 180 species, or some 80 % of the total. Basically, it is an overview of the world’s 226 shorebird (in Europe: wader) species (following the IOC checklist), proceeded by essays on their plumages and behavior. What is it, then? Have you ever heard of it?
All species are from the ABA area, and all groups must meet at least one of these criteria: (1) the group “represented a good opportunity to build core birding skills,” (2) the authors thought it was a group that needed “a refreshed treatment,” (3) the authors were intrigued by the group and wanted to present it using their unique format.
I was surprised that this species is named for its vocalization – which sounds like laughter. For example, the Diamond Dove is the world’s second-smallest species of the columbidae order ( source ). The Latin species name haematonotus (“blood-backed”) sounds a bit more exciting but not necessarily more accurate.
The warm, sunny climate beckons a wide variety of passerines, raptors, and shorebirds to spend the winter, inflating the species diversity to the extent that Miami-Dade can go toe-to-toe with counties in Texas and Arizona during this season. Can we hit 200 ABA-countable species in four days next year?
Since discovering our first Pied Oystercatcher nest on Cable Beach in July 2000 we have observed the breeding of these local shorebirds along the coast between Gantheaume Point in the south and Willie Creek in the north, which is a distance of 23 kilometres. For birds that rarely fly they were suddenly constantly in the air.
The one bird I did not see here, however, was the Bateleur Eagle … One highlight in the area is the Saddle-billed Stork , likely to be the tallest species in the stork family. The African Spoonbill is one of the six global spoonbill species, and the main African one (there are also some Eurasian Spoonbills in Africa).
Breeding bird surveys appears to show the resplendent Allen’s Hummingbird (like Corey’s capture, above) in decline—but not in Southern California, where examination of eBird data reveals that members of a residential population appear to be faring much better than their migrating brethren. sports championships ).
He brings to this book an academic background in biology and horticulture and, more importantly, decades of experience developing strategies for the best backyard bird feeding practices. There is also a major section on 180 bird species that is 123 pages long, about 1/3 of the book. The latter appear to be suburban apartments.
