Annual report.

Nest box 10.           2004.
Built-in observation box
The nest box northerly
Results
3 eggs
2 young common swifts

  I think that one Common Swift didn't come back and the Common Swift that, at the end of the season stays in nest box 12, has taking his place. This is based on the behaviour of one of the birds during the first days of the season. As long as we cannot identify we must guess.
This year we also have follow the Common Swifts in detail from arrive until leaving by detect system.
The report is completed with photos and a sound of fighting Common Swifts. (Digital logbook)
