| Abstract | Good estimates of the genetic parameters of natural populations, such as heritability, are essential for both understanding how genetic variation is maintained and estimating a population’s evolutionary potential. Long-term studies on birds are especially amenable for calculating such estimates because of the ease with which pedigrees can be inferred. Recent ‘animal model’ methodology, originally developed by animal breeders to identify animals of high genetic merit, has been applied to natural bird populations of known pedigree. Animal models are more powerful than traditional analyses such as parent–offspring regression because they use all of the available pedigree information simultaneously. In doing so, they can accommodate common phenomena like selection and inbreeding and are especially suitable for the complex and incomplete pedigrees typical of natural populations. Animal models not only provide a better way of estimating genetic and environmental variance components, they also allow individual phenotypes to be separated into their genetic and environmental components. Here we aim to provide the interested ornithologist with an accessible entry into the vast and sometimes daunting quantitative genetics literature and, in particular, into the literature on the animal model. We outline not only the possibilities offered by the animal model for the accurate estimation of genetic parameters in the wild but also associated potential pitfalls and limitations. On the whole, we aim to provide an accessible and up-to-date overview of the rapidly developing and exciting field of evolutionary genetics applied to long-term studies of wild bird populations. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
