The Socotra Grosbeak Rhynchostruthus socotranus is a bird that is native to the Indian Ocean. The population of these kinds of finches has significantly decreased over the years. These species are also known as Golden-winged Grosbeak. The plumage of males is brownish and a black bill together...
Species recognition in Darwin’s finches (Geospiza, Gould). III. Male responses to playback of different song types, dialects and heterospecific songs - Ratcliffe, Grant - 1985 () Citation Context ...st and/or most bulbous bills of these assemblages. Bill shape could therefore be important ...
Peter Grant and colleagues tested Gause's principle by studying seed-eating finches (birds) that live on the Galapagos Islands in the Pacific Ocean. They found that different finch species can coexist if they have traits that allow them to specialize on particular resources. For example, two fin...
If all finches (雀科鸣鸟) were identical, for example, and their environment changed in some significant, harmful ways, like an increase in the temperature or a decrease in water, all of them would be equally affected and the species might become extinct. This insight into variation comes ...
Among them, the zebra finch (Taeniopygia guttata) has been widely used as a model species to study the behavioral, cellular and molecular substrates of vocal learning. Various methods using taped song playback have been used in the laboratory to train young male finches to learn a song. Since...
Birds-Of-Paradise Blue Bird Of Paradise Order: Passeriformes Family: Paradisaeidae Birds of paradise are famous for the elaborate and brightly-colored plumage of many of the males. There are 42 species in the birds of paradise family, Paradisaeidae. They are found in eastern Indonesia, Papua...
A new study sheds light on how sensitivity to communication sounds is established in the brain. Juvenile finches raised with tutors of either the same or different species always learned the tutors' songs. Cortical neurons developed selectivity for the learned song by tuning for its secondary ...
For greenfinches, songs from different places in Europe have been studied. It has been determined which characteristics are constant (typical for all songs) and which are variable (typical for one place only). The song of greenfinches is not stereotyped: a given song element may be followed ...
If Sea World can't attract and retain visitor loyalty on its own merits, WITHOUT misleading said visitors about things our species has been doing for the past few thousand years, then maybe they need to do some serious reexamination of their true goals....
illustrate that there is probably not ‘one form’ of reciprocity (Table1; see also the glossary Online Supplementary Material, S1). Yet, many studies did not differentiate between them; consequently, we thus lack knowledge on the use of different strategies and mechanisms in many species. ...
