“I don’t know anyone else crazy enough to try 12s,” my friend answered when told that I am about to test NL Pure 12×42. With such a background, my decision to test the new birding frontier of Swarovski 12×42 extra-wide FOV binoculars didn’t appear strange at all – to me, at least. What do you think? Are 12s right for birding?
The feature distinguishes birds from other species; All birds have them, no other species do. Beaks vary across different kinds of birds, and this great diversity in beaks is part of the great diversity of the 10,000+ species of birds that exist today; Beaks thus facilitated the diversification of birds. So how did beaks evolve?
Founded by Roberto Chavarro and his family in the early eighties, this little reserve has been dropped slap-bang into the birding spotlight by the recent claims of the rediscovery of the Bogota Sunangel Heliangelus zusii , a species that is known from one record – a skin from 1909! How much variation was there in this species?
Given how far Hokkaido is from Europe, it seems a bit surprising how many bird species wintering on this Japanese island have a name starting with “Eurasian” Or how many of these species I have also seen in my parents’ garden in Germany. It seems extra-pair paternity is very frequent in this species.
We can, of course, count wild, native, species. We can count vagrant species that made it to the area we are in under their own power. We can count introduced species that have met the criteria of the “Bird Police” for the area to which they are introduced. There are lots of birds we can’t count.
But how birds use these different senses, like the diversity in bill size and shape, varies almost as much from species to species. Chickens come in at around 24, pigeons have around 40-50 and some duck species may have a whopping 400. Honeyguides, for example, are strongly attracted to the smell of wax.
As one topic example, Marconi Campos-Cerqueira presented a paper entitled “Past, Current and Future Distributions of Puerto Rican Fauna: Implications from Climate Change.” He modeled likely future suitable habitats in a climate change scenario for a number of bird species of conservation concern.
For example, many photos are shot in poor light, obscuring the true colours. Lees and Gilroy delineate vagrancy status and trends for every bird family worldwide, highlighting examples, synthesizing research, and framing it all with their own thoughts and conclusions. Yes, this is a shameless plug, but it’s also true.].
Covid turned out not to be too much of a hindrance – I had to show a negative PCR test upon arrival on Hainan from Shanghai, and while many Chinese hotels currently do not accept foreigners, I could leave this issue to my guide. This species seems to enjoy being in mixed flocks with the White-shouldered Starling.
Looking for Northern Shrikes and redpolls was a test for winter gear and wind chill factors but the birds weren’t going to be there in the hot days of summer. For example, around here, we have to watch our step for vipers wonderfully camouflaged in the leaf litter. Add 10 species to my Costa Rica list. Promote birding.
More than 5,000 bird species in the world make some kind of seasonal movement. He gives lots of marvelous examples, such as the Blackpoll warbler, “among the most astonishing and extreme of all migratory birds.”. As a test of endurance, as a physical ordeal, it’s both miraculous and monstrous.” Eighty hours of flying.
The smellier the better, particularly as, unusually for birds, many species can boast a robust sense of smell. In any case, our hang-ups with vultures clearly stem from our own issues rather than any inherently bizarre trait of the species themselves. Vultures famously feed on carrion. Dead things. New World Vultures.
Hunting sandhill cranes in Kentucky is a bad idea from a public relations standpoint, considering the growing cadre of birders and nature enthusiasts for whom cranes are a touchstone species. Initiating a hunting season on a large, charismatic species like a crane is no way to resuscitate hunting.
The book is divided into three parts: “Introduction,” “Avifaunal Overview,” and “Species Accounts.” The authors’ detailed delineation of problems with the accuracy of NYC breeding bird surveys or with the limits of historical writings may test a reader’s patience. Most birders will go straight to the “Species Accounts.”
One big example of change this week was that as I was brushing my teeth at 4:35 am and it was the first time that a robin was not singing on territory outside my bathroom window, summer is on the downswing already. Each week a new species tried to test the patch for nesting territory. The first week it was a Sedge Wren.
Where predators are rare, turning more attention to feeding might produce a Darwinian benefit, for example. Most likely, all individuals of a given species have very similar genes guiding very similar developmental processes, but produce different results because the plasticity itself is selected for. Invasion of the birdie snatchers.
I was still telling the truth when I mentioned the four subspecies, species, taxa, forms, you name it, of the Great Egret: modesta (Asia), alba (Europe, Asia), egretta (Americas) and melanorhynchos (Africa). Absolute field marks between two similar species describe a difference that can be judged definitely by looking at a single bird.
Even if you don’t live in the summer range of a particular species, you may have opportunities to observe it while it passes through, especailly if you live in an active flyway, like I happen to. Because the ancestor of this species of bird migrated, and the migratory adaptation and all that entails were passed on.
The field site I am assigned to is located in one of the most diverse ecosystems in the world and home to a particularly rich avifauna that numbers well over 500 species. Hundreds of riotously colored birds representing 14 species of macaws and parrots flock and frolic together in less than fifty meters of forest canopy.
Even more than warbler, shorebird, and sparrow identification, this is a field that tests our endurance (gull watching is too often done in bitter cold, windy conditions), patience (even getting one good photo can take hours as you try to separate the ‘interesting gull’ from the flock), observational skills (so many plumages!)
Understanding a pointed finger may seem easy, but consider this: while humans and canines can do it naturally, no other known species in the animal kingdom can. It’s no coincidence that the two species that pass Hare’s pointing test also share a profound cross-species bond.
Described in the “Territoriality and aggression” chapter, this is a sublime example of behaviour from the “Understanding Animal Behaviour” by Rory Putman, an Emeritus Chair in Behavioural and Environmental Biology at Manchester Metropolitan University, UK. Cactus finch, Geospiza species. Galapagos cactus finch, Geospiza species.
” Funny how the difficulty of breeding a species can be illustrated in simple monetary terms. But that may have helped me to see them – the species is quite nomadic and settles wherever there is rain. Ok, back to the (presumably non-sacred, certainly non-mummified) Australian species. In a paper published in 1938 (!),
When we scuff our knees and test the resiliency of our joints to peer into a bush at a Swainson’s Warbler in an urban park? Ok, that last example might be more indicative of obsession than something from the world of Doug Henning but I bet you get the point. I hope I see a White-bellied Mountain-gem.
Here is an AP story highlighting the impact these pharmaceutical substances are having on aquatic and avian species. For example, exposure to these substances is negatively impacting the reproductive abilities of some fish species, threatening their extinction. It's a problem for animals, particularly aquatic animals, as well.
For example, we might just enjoy the calls and antics of those White-throated Sparrows while searching for a Harris’s. Most of all, I love showing people birds, species both common and mysteriously evasive. Whether a birder is eager for eyefulls of common species or needs to test the birding Zen and.
Phoebe Snetsinger was an American birder who first passed the 8,000 species mark. Before leaving the safety of the car I heeded the park’s advice and checked for animal tracks belonging to any biting, gnawing, mauling, trampling, stabbing or disembowelling species. She died in a car accident during a birding trip.
You’re a mammal, so you might be tempted to use yourself as an example mammal, but humans are actually kind of bad examples of mammals, so perhaps we’ll use a well studied hoofed animal instead. Think about the difference between birds and mammals. Prior to insemination, things are different as well.
Bill Schmoker , Nikon Birding ProStaff member, and I spent a day in the field testing the new Nikon EDG VR Fieldscope. Ultimately, this species can look drastically different in their molting phases, but this bird should prove to be a male. So, how about this adult female Common Goldeneye for example.
One of the most spectacular examples of communication among birds that is all about mating but involves no song is the bower and gifts assembled by the male bower bird, where just like in humans, a nice place to hang out, a pile of cool but useless presents, and excellent dancing often leads to a second date.
When it comes to breeding, Yellow-rumped Warblers are a good example of what many people regard as a “regular” bird. Greater White-fronted Geese are one of many species that mate for life. This is just a small slice of how birds get it done. Other infamous brood parasites include cowbirds and Old World cuckoos.
It’s easy for West Coast birders to covet the variety of wood-warblers back east, while eastern birders may lament the dearth of hummingbird species on their side of the continent. There was also a certain appeal to bravado in testing one’s mettle by downing the latest “hop bomb”. Of course, reading field guides breeds jealousy.
One of the nestlings decided to test its flight feathers during the photo shoot, to the dismay of its sibling. There are several species of birds whose eye color changes from birth to adulthood. One species, in which you may be familiar with this phenomenon, is the Red-tailed Hawk (Buteo jamaicensis).
The best female strategy seems to be to mate with as many of the males as possible, as this means more help in feeding the chicks by all the potential fathers (I guess the fathers do not have easy access to paternity tests). They found that the species is diurnal (well, using cameras, would they even have seen nightly activities?),
There is much to enjoy and appreciate here and I only wish I could have tested out some of these species accounts in pelagic waters before writing about them (sadly, the 10,000 Birds pelagic to Antarctica was canceled this year). SCOPE & SPECIES ORGANIZATION. It covers 434 species across 9 orders and 18 families of birds.
But off the top of my head, I cannot think of any examples of non-exploratory people who are open to the unexpected at home. Researchers comparing these traits across groups of closely related species – parrots, tits, sparrows, darwins finches etc – find no general correlation between neophobia and exploration.
1 spot Sprintally: Not included in the top 10 (despite some rather broad “bird species” making into the list, e.g. “kingfisher”) Chipper Birds : This is a list of the top 30 but the Golden Pheasant is listed as No. ” Owlcation: Included at number 7 but species may not be listed in any particular order.
The species name is cyanouroptera , meaning dark blue tailed and -winged. Of course, me writing about the meaning of “gorgeted” rather than providing bird-specific information indicates a lack of papers on the species. In fact, Spectacled Barwings wearing contact lenses are easily mistaken for this other species.
For example, without this blog, would you know that the Barn Swallows of Nanhui are now having their own housing boom, ignorant of the overinvestment that has characterized China’s construction industry? Chestnut-winged Cuckoo: This could be your host species! Yes, you do, trust me. Arguments in favor: 1. It looks nice 2.
