Wetland Bird Survey (I-WeBS)
Ireland Wetland bird survey counts of
Rogerstown Estuary
The birds of Fingal's estuaries and
coast line are counted once a month between September and March as part of
I-WeBS. The counts have to be coordinated to provide accurate numbers as birds
frequently move from one area to another. For Rogerstown a team of counters meet
up and are given a section of the estuary to count. The numbers and then
correlated and passed onto the I-WeBS office. The results are published annually
and are used to track population trends over time.
