And then I saw the species names attached to the aforementioned gentlemen’s avian namesakes and gave up… So, my attempt at political correctness has been thwarted by the 18th century rules of taxonomy. Not only did my research show a lot of promising sites to visit, but I also have two good birding friends in the region, Laura and Brad.

I have always assumed that scientific researchers can overlay weather information on checklists for their research, but absent manual entry, that such information would not be available to me. I find the information helpful and insightful, as it can shed light on why some species were or were not seen on that trip.

He also believes that we are living in an era of incredible scientific research, one in which new genetic technology and findings from diverse scientific disciplines have turned assumptions upside down, opened up new lines of thought, and provided answers, or at least probable answers, to many of our questions about why birds do the things they do.

The Northern Spotted Owl is a “ threatened ” species under the U.S. Endangered Species Act and it was famously the subject of extensive and protracted litigation in the late 1980s and early 1990s, mostly relating to forestry management plans in the Pacific Northwest. A sample of this process is here.)

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?

Since the books share authors and a creation process, I thought I would review them together. It’s not clear how many of the plates have been touched up, redrawn or are new, and I hope we’ll learn more about the process, perhaps when the third book in the series by Howell and Dyer, a new guide to the birds of Mexico, is published.*

This leaves Shanghai in June with basically just the year-round species and the summer breeders, maybe with a few added ultra-lazy individuals of migratory species. Fortunately, there are a few more such breeding species than most Shanghainese are aware of. Such as the Black-winged Cuckooshrike.

If I was an ornithologist aiming for a grant, I would now definitely highlight the need for more research on this topic. The Grey-Streaked Flycatcher looks only marginally more interesting, and while the Latin species name griseisticta sounds vaguely mysterious, it only means grey-spotted.

Every time a gene is replicated, or really, a chromosome (during cell division), a bit of the end of a gene may be lost, owing to the way this process happens. This is part of the process of aging. Research done quite a while back suggests that this is adaptive. City Great Tit ( Parus major ) telomeres shortened.

GISS—general impression, size, shape—is intuitive, the result of an unconscious cognitive process derived from experience in the field. It is not a handbook, though it approaches species from a collective viewpoint. Experienced birders can identify birds using GISS; all birders can identify birds if they adopt the BBI approach.

The new-growth forests might seem to be in good shape, the researchers point out, but since avifauna (like Rusty-margined Guan , above, photographed by Enrico Zimbres and shared on Wikimedia Commons) have not fully taken to them, these trees are fighting an uphill battle for survival. The trees are also likely to disappear over time.”.

Howell and Sullivan have taken apart the identification process and turned it around, placing macro aspects first in importance (location, habitat, season), followed by situational factors (lighting, distance), behavior of the bird (what it is doing and how it sounds), and, finally, what the bird looks like (structure, plumage, variation).

Major extinction events that are geologically instantaneous have been followed by periods of time with reduction of species or unstable habitats that last for hundreds of thousands or millions of years. There are about 10,000 species of them, after all, which is a lot for a vertebrate. Here, according to the research , there is.

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.

It’s the process of using knowledge of natural history, habitat, distribution, behavior, and, yes, taxonomy, combined with specifics of adult and juvenile plumage and vocalization to identify a bird, often to the subspecies. The process is called “Wide-angle birding: Be the bird, see the bird.”. It is an intriguing choice of species.

Birding is discussed as a process that involves finding birds, viewing and hearing birds, taking notes and sketching birds, thinking about habitat and migration, and then, identifying birds. It is process that can be as simple or as complex as you wish, and I think this is where Birding for the Curious is unique.

However, given the correlative nature of this study, other processes, including stochastic shifts in the frequency and distribution of mtDNA that may have produced this mtDNA-nuDNA discordance (and any correlated phenotypic differences), should not be excluded.

Back in the 1980s, it became popular for biologists to consider plant secondary compounds in understanding inter-species relationships and other ecological matters. Some bird species, for example, bring fresh plants to the nest, which contain volatile compounds that repel parasites. The next stage in this research is obvious.

For example, if we hear distant thunder, we know that it was caused by a storm, or by lightning, or by the more precisely defined physical processes of ionized air (depending on how much we know about meteorology).

Third, observing and photographing breeding birds and their young have become acts of ethical confusion as birders, photographers, and organizational representatives debate the impact of our human presence on the nesting process. Some chapters focus on one species (Yellow Warbler), some on several related species (Chickadees and Nuthatches).
