| Abstract | Signal behavior of three crane species was chosen to test the logic of the ritualization hypothesis. Its claims to explain the origin and functioning of the “highly ritualized” communication signals in birds are discussed. It is shown that such signals are observed in a wide range of situations, including those in the absence of a social partner for communication (perceiver). In its presence a signal may be performed in a way that it cannot be perceived by the partner. The same actions (“ritualized preening”) vary in length and intensity, and such variability is present in nearly all situations. In each situation, it is difficult to discriminate between the ritualized preening and actual comfort behavior. It may take place even when a social partner is present. Short preening that may be readily considered as ritualized signals are more common in the all situations, including those with an absent partner. The endogenous cyclicity in unison calling by mates indicates that communication cannot be regarded as a simple exchange of signals in accordance to the ‘stimulus-reaction’ principle. Similar actions by the more ancestral Siberian Crane may appear to be more ritualized than in the evolutionary advanced Red-crowned Crane. All these findings contradict the concept of emancipation and ritualization of behavioral actions during evolution and selection for increasing communication efficiency. According to that hypothesis, during this process such actions, due to selection for more efficient communication, evolve into discrete meaningful communication signals (displays). They stand out against the background of the monotonous, unexpressive (non-signal) everyday behavior and thus appear as the main carriers of information serving principal communication functions. A more realistic approach seems to be the understanding of communication as a process of a continuous mutual fine-tuning of the social partners’ behavioral attitudes towards each other. In either participant, its behavior is an integral structure, inseparable into categories of more or less important signals (flow of behavior). Even minor changes in performance by one individual reflect alteration in its motivational state which, in its turn, changes that of the other participant and the subsequent lines of its behavior. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
