BIRD NUMBERS

The newsletter of the Avian Demography Unit

Volume 10 Number 2, December 2001

    © Avian Demography Unit 2001

BIRD NUMBERS is published by the AVIAN DEMOGRAPHY UNIT (ADU), Department of Statistical Sciences, University of Cape Town, Rondebosch, 7701, South Africa. It is distributed free of charge to ADU project participants.

The ADU is a research unit of the University of Cape Town and enjoys the partnership of BirdLife South Africa.

The mission of the Avian Demography Unit is to contribute to the improved understanding of bird populations, especially bird population dynamics, and thus make a contribution to their conservation. We achieve this through mass-participation projects, long-term monitoring, innovative statistical modelling and population-level interpretation of results. The emphasis is on the curation, analysis, publication and dissemination of data.
