What were the birds doing?
When participants entered their information about active nests on the website, they were asked to describe the status of the nest. For most species, nests were most commonly observed either when they were being built or when chicks were present.
For example, on 21% of the occasions when an active Blackbird nest was recorded it was being built, and 28% of the time chicks were present.
Nest building and feeding chicks are two conspicuous activities, when parent birds are busy entering and leaving the nest frequently, in contrast to incubation, when one parent will sit quietly and inconspicuously on the nest for long periods of time.
