a

Total number of admissions at the center during the period of the study.

b

Estimation of resident population (individuals) of the region during the wintering and breeding seasons according to the Catalan wintering bird Atlas 2009 and the Catalan breeding bird Atlas 1999-2002. Post-nuptial migration population is highly fluctuant and is not considered.

c

Seasonal cumulative incidence (SCI) cases per 1000 animal/year =  [(total season casesa/estimated season populationb)* 1000]/12.

d

Number of individuals. Estimated population at the breeding season was calculated from the number of pairs multiplied by the number of chicks.

*Only species with at least up to 100 cases are represented in the table.

W =  Wintering period; B =  Breeding period.
