The association ANUUMigrators has published a new weekly note concerning the migration pass. The meteorological change long awaited came later a rainless August, except for thunderstorms, which have caused more harm than well-being. The abundant rainfall coincided with the first two weeks of this September, especially on the weekend of Saturday 9 and Sunday 10.
Migration has retreated a lot precisely because of the temperatures above the seasonal norm, so much so that the numbers of catches were much lower compared to the monthly total of the past years. We are talking about the period monitored by the FEIN Ornithological Observatory of Arosio, in the province of Como. The last week of August was characterized by the light migratory movement of black nannies and prispoloni.
The meteorological change in September made it possible to register a good movement, specifically once again with regard to the prispoloni, without forgetting the black nurses (the number is still lower if compared with previous years). Finally, on the 9th and 10th, the windows of heaven opened and for the summers, the season cannot yet be defined.
