Introduction

Bird banding and marking are important tools used in research. They help to provide the data required to answer questions regarding the biology and movements of individual birds.

Banding can give us information on the average survival and life expectancy of birds, the age at which breeding first occurs and the number of years of reproductive potential for each species. It can help to measure the annual variation in numbers of adults and young birds, and give insight into causes of avian mortality.

Banding helps researchers map the location of the summer and wintering grounds and rest areas as well as the routes followed by migrants. Recovery of banded birds yields information on the timing and duration of migration. It also helps us to determine which species are changing their migratory patterns.
