According to Wikipedia, birds (class Aves) are feathered, winged, two-legged, warm-blooded, egg-laying vertebrates. Most researchers agree that modern-day birds are the only living members of the Dinosauria clade. After all, they are the species that got me started building nest boxes in the first place.

But does the value of a particular trip come from the number of birds seen, viewing a particular species, seeing an endangered species, catching a glimpse of a rarity, adding a lifer, or something else? I emailed the authors and asked about their research and their use of eBird data. Birders derive “value” from birding.

You see, up to this point, let’s say 1972, perhaps 1973, I had never really been exposed to a “Threatened, or Endangered” species of any kind. The State of Oregon, in 1975 listed the bird as Threatened, and the Oregon Fish and Wildlife reaffirmed that status in 1989 under the Oregon Endangered Species Act.

An associated issue is that the Belize and Costa Rica guides share many of the same descriptions of species, written by Howell. Similarly, descriptions of species repeated across volumes do not lose their accuracy with each publication. Other species are splits and lumped and have had their names changed. Why are these issues?

We are facing a plague of poaching that is again decimating the species. A different research says, from 2002 to 2011 the known populations of forest elephants declined by 62%. The way I see it, it is a cruel joke leading towards the extinction of a threatened species. In Africa, one elephant is being killed every 15 minutes.

Birding by Impression is a conscious, deliberate method of identifying and recognizing birds based on the study and evaluation of “distinctive structural features and behavioral movements” and comparison with nearby and similar species. It is not a handbook, though it approaches species from a collective viewpoint. .* So say Kevin T.

Shockingly, the Ashy-throated Parrotbill apparently is a species heavily hunted for bird fighting in Guizhou Province, China ( source ). Shame on the researchers. The other is to mention that the name commemorates Edward Blyth (1810-1873), who published the first description of the species.

The trait must then be identifiable as to whether or not it exists in a certain species. The traits have to be unambiguously linked to the entities we are calling extinct species and thus, the traits are unambiguously linked to each other. This requires a few things to be true, depending on the fossils. What evolved into what?

The Ashy Tailorbird is a good example of the different perspectives of describing a bird – while the English name focuses on the body of the bird, the Latin species name ruficeps refers to the rufous head. The split makes the bird one of the six species endemic to Sabah, Borneo ( source ), four of which I saw during my week at Sepilok.

I guess most scientists would love to see their original research become the basis for a vast field of further studies.
