Official URL: http://www.euskomedia.org/analitica/6367 AbstractIn 1995 a methodological project was started with the objective of carrying out the standard tracking of the Turtle Dove (Streptopelia turtur) reproductive period in Portugal. The results presented correspond to a 6-year annual series, which represents the national total. The method used followed transects marked in the best nesting areas for this species. Preliminary conclusions show an initial descent in the reproduction rate and a significant recovery over the last few years. Out of the whole reproductive period, June is the month that presents the highest reproduction rate.
