PVC nest.

During the period that takes the reproduction season, from June to August 2005, were maintained and substituted 30 artificial nest boxes previously installed. Material to make 40 more nests were acquired, 10 of which substituted damaged ones. The boxes were installed mainly on locations were the loss of trees and natural nests has taken place. After being installed the artificial nests are being monitored weekly through the reproductive season.

During the monitoring (October/2005 – April/2006) we will keep track of the development of the offspring through the survey on biological, behavioural, and veterinarian information, up to the post fledging period. The artificial nests will be plotted in maps through geographic information system. At the end of the reproductive season the reproductive success will be evaluated. All installed nests will receive a new inspection for cleaning, restoration and, if necessary, substitution for new ones.

The checking out artificial nests will be carried out between June and October 2006 after the reproduction period. In this period, will continued maintenance and/or the restoring and the construction of new artificial nests. For this, all the reproduction area will checked for the conditions of the artificial nests and also to verify which were the necessary measures for its maintenance. Material to make more nests will be acquired. The boxes will be installed mainly on locations where the loss of trees and natural nests has taken place. After being installed the artificial nests will be monitored weekly through the reproductive season, from October 2006 to April 2007.
