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. In science speak, this is named the optimal body mass hypothesis.
The birds were too far away to identify, and I know more than one species does this, but if I had to guess they were starlings. There is a bit of science news. If half the Warblers go extinct, that would be a lot of species but you’d still pretty much have Warbler DNA. But there were a gazillion of them. This makes sense.
The first half describes the problem (why birds hit windows, the scale of the deaths, scientific research, what happens when birds strike windows) and the second half discusses what to do about it (community and worldwide education, window deterrent solutions, legal mandates and building codes, citizen science–what individuals can do).
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. Way back when I started what turned out to be my thesis research (on humans), it became important for me to learn about bird migration.
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.
March 14, 2011 Kentucky Department of Fish and Wildlife Jon Gassett, Commissioner One Sportsman’s Lane Frankfort, Kentucky 40601 Dear Mr. Gassett, I am a writer, naturalist and artist with a special interest in human/bird interactions. This slow reproduction rate is unlike any other avian game species currently hunted.
The book is divided into three parts: “Introduction,” “Avifaunal Overview,” and “Species Accounts.” Not all habitat change is due to humans; there is Chestnut Blight destroying American Chestnuts in the early 1900s, and the more recent Dutch Elm disease. Most birders will go straight to the “Species Accounts.”
” 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. was responsible for maintaining the universe, judging the dead, and for writing and science ( source ).
This non-technical book is a development from a series of lectures, tried and tested in numerous adult education courses given to non-specialists. Those bears live in the wild and are not used to humans. Cactus finch, Geospiza species. Galapagos cactus finch, Geospiza species. Blackcap, Sylvia atricapilla.
Farm animals also benefit from the humane farming movement, even if the animal welfare changes it effects are not all that we should hope and work for. Go vegan, go vegetarian, go humane or just eat less meat. If we all decide to consider animals as precious as humans, the only logical place for us is back in the jungle.
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?),
