Just last year, 5 new bird species and 5 new subspecies were discovered in a few short weeks of fieldwork on the islands of Taliabu, Peleng and Batudaka. In recent years Indonesia has been competing with the Andes as the region giving rise to the biggest number of undescribed bird species (naturally, all of them endemics).

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. My research in the Congo supports this idea. During the former periods, we certainly came across animals, but rarely.

This example is important because it appears that the protector species, not just the protected species, gains a benefit, the latter having been documented many times before.

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. .*

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.

Well, in comparison to many other birds, young ravens leave the nest earlier and are thus more clumsy and helpless when they are found on the ground or on low branches, all by themselves. As a rule of thumb, with quite a number of exceptions, if the species sports feathery ears and is not an eagle-owls, it’s an “Eule“.
