Population justification: The population on Réunion has been estimated at over 10,000 mature individuals (V. Bretagnolle in litt. 1999, M. le Corre in litt. 1999) and on Mauritius there is an estimated minimum of 2,244-2,610 birds (G. Middleton per C. Jones in litt. 2000), thus the total population is expected to fall within the range 10,000-19,999 individuals. This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals. |
|
Trend justification: Over recent years, the population on Réunion has increased substantially (A. Cheke verbally 2000), whilst that on Mauritius has declined, making it difficult to judge the overall population trend. |
