Key messages

A small study from Puerto Rico found that nine Puerto Rican parrot Amazona vittata nests were repaired, resulting in no chicks dying of cold.

 

About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. A small study on nest success of Puerto Rican parrots Amazona vittata in the Luquillo Mountains, Puerto Rico, between 1973 and 1989 (Lindsey 1992) found that nest guarding and repair work by volunteers and biologists/technicians prevented the failure of nine nests in nest holes that had wet cavities, which, without repair, would have resulted in the eggs becoming chilled. A total of 71 nests were guarded. This study is also discussed in ‘Guard nests to increase nest success’.
