| Abstract | Paridae are among the bird families benefiting from food storing. However, not all its members hoard food. Our objective was to clarify the role of ecological factors in occurrence of food storing. We reviewed the data on major ecological characteristics of the Paridae species and analysed their association with the presence/absence of food storing. Our statistical model revealed that geography (distribution in North America) and taxonomy (genus Poecile) are better predictors of food storing than any of the studied ecological traits. Nevertheless, food-storing Poecile species inhabit mixed or coniferous woodlands with seasonal richness of food, while non-storing species tend to prefer edge and open habitats, where alternative food sources are available. Sociality and territoriality outside breeding season coincides with food storing. The analysis performed within the Baeolophus–Lophophanes–Periparus–Poecile clade with ancestral food storing revealed no factor except continental climate that would explain the persistence of food storing. The phylogenetic analysis of ancestral states of the studied characters allowed us to propose a possible scenario for the emergence of food storing in Paridae. (1) Food storing is not ancestral in Paridae and appeared only once in the common ancestor of the Baeolophus–Lophophanes–Periparus–Poecile group. (2) According to estimation of molecular clock in Paridae, food storing appeared before their radiation in North America. |

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.
