                       of habitats.

                       habitat.
F  -  Fairly common    Likely to find in small numbers on most days in suitable
                       habitat.
U  -  Uncommon         Possible to find in small numbers on one in four days in
                       suitable habitat.
R  -  Rare             Seldom found in any numbers even in suitable habitat.
X  -  Extremely rare   Found only in some years and only one or two occurences in
                       the season.

Abundance ratings reflect the success rate of experienced birders who are familiar with available habitat within the county and the habitat requirements for the particular species.
