Ornithological Society – Nest Record Scheme

The object of the scheme is to provide data on length, time and peak of breeding seasons, clutch size, number of clutches, incubation and fledgling periods, nest sites and materials used in nest building, to provide an abundant and comprehensive data on bird breeding habits and success. Hundreds of cards are needed before a valid analysis can be attempted for any one species and hundreds more to confirm results of the first analysis and show what variations occur between seasons or between districts.

Data on length, time and peak of breeding seasons, clutch size, number of clutches, incubation and fledgling periods, nest sites and materials used in nest building.
