THEANUU he wanted to remember with a press release the ringing of the first song thrush in post-nuptial migration 2017 (the period between September and November) at theOrnithological Observatory of the European Foundation Il Nibbio di Arosio (province of Como). It is a young specimen that was captured at 6 am yesterday, Wednesday 13 September 2017: the ringing took place immediately after with a ring Z494463.
Based on the provisions of the Euring (The European Union for Bird Ringing) directives, the bird was subjected to biometric measurements, in addition to the detection of fat, muscle, weight, chord, third and tarsus. The ringing of the Observatory has been going on since 1975 and this year it took place on a date that is judged to be normal.
The greatest delay in this regard was recorded on September 21th 2006, while the earliest capture occurred on September 3th (both in 1977 and 2003). Among other things, the date of this year coincides with that of 2007. The day of the capture was characterized by Nice weather since the morning, with the sun rather hot.
