As announced by the association ANUUMigrators, first prispolone in post-nuptial migration was ringed at theArosio Ornithological Observatory, in the province of Como. This is the structure managed by the European Foundation Il Nibbio (FEIN) and the event dates back to last August 16th, to be precise at 8:XNUMX am. overcast sun and temperatures around 25 degrees.
The date almost two weeks ago represents the second time ever after twenty-six years of monitoring. The first prispoloni in this area of Lombardy, ringed with five specimens. Since 1993, the year in which the first catches of some target species are indicated, this date was only reported in 1994 with a ringed specimen. In addition to the black Balia which has been noticed in a continuous and very modest form, there is the arrival of the Pigliacatcher, the Redstart, the Canapino, the Cannaiola and the Beccafico with the Bigiarella.
The big Luì and the green Luì were also present. If the good weather continues with the favor of the moon which reached its maximum splendor on the night of Sant'Alessandro (August 26), traditional date for the summers, there is hope for a good migration after this weekend's weather change. We will talk about it again next week.
