Hunting and Migration: ANUU, completed the eighteenth year of survey as part of the Wintering Project.
With the sunny day of January 25, 2014, the 18th year of the Wintering Project ended, relating to the monitoring of avifauna through the scientific ringing technique carried out at the FEIN Ornithological Observatory of Arosio (CO). The Project is coordinated by the Higher Institute for Environmental Protection and Research (ISPRA) based in Ozzano dell'Emilia (BO). During the monitoring 4 transects of mist-nets were used, for a total of 140 m., Positioned in different environments. At the Arosian station the technical staff carried out 6 study days divided into three in December 2013 (8-14-30) and three in January 2014 (3-11-25) analyzing 30 subjects belonging to 9 different species . The subjects analyzed in this last phase are added to those ringed within the project since 1996, thus reaching 1.702 subjects, of which 52 in the period 1996/97, 86 in 1997/98, 86 in 1998/99, 185 in 1999/2000, 103 in 2000/01, 215 in 2001/02, 159 in 2002/03, 89 in 2003/04, 46 in 2004/05, 53 in 2005/06, 37 in 2006/07, 179 in 2007/08, 112 in 2008/09, 47 in 2009/10, 73 in 2010/11, 53 in 2011/12 and 99 in 2012/13.
Also in this eighteenth year, the species analyzed were: the Great Tit with 14 subjects analyzed, the Robin with 6 subjects, the Marsh Tit with 3 subjects, the Long-tailed Tit with 2, the Fiorrancino, the Blue Tit, the Chaffinch, the Sparrow and the Redwing with a single subject. Among the subjects analyzed, as many as 25 were self-catching, that is birds that at the time of capture already had a ring in the tarsus, placed before the project was carried out, again at the Arosio Observatory.
In total, therefore, the different ringed species since 1996 have been 29, belonging to 12 families of European avifauna such as Finches (Chaffinch, Peppola, Greenfinch, Siskin, Frosone and Goldfinch), Paridae (Great Tit, Blue Tit, Marsh Tit, Coal Tit , Long-tailed Tit), Turdidae (Robin, Blackbird, Song Thrush, Redwing and Cesena Thrush), Silvidae (Small Luì, Blackcap, Regulus and Fiorrancino), Picidi (Great Spotted Woodpecker and Green Woodpecker), Certidae (Common Rampichino), Motacillidae (Ballerina yellow), Accipitridae (Sparrowhawk), Columbidae (Eastern Collared Dove), Ploceidae (Italian Sparrow), Prunellidae (Sparrow) and Sittidae (Nuthatch).
Also during this last phase of the project 8X50 binoculars were used with which, respecting the times and considering six cardinal points outside the capture systems arranged one to the north, one to the north-west, one to the north -east, one south-west, one south-east and one south, it was possible to observe, in addition to the analyzed species, also the Wren, the Blackbird, the Regulus, the Coal Tit, the Siskin, the Great Spotted Woodpecker , the Green Woodpecker, the Nuthatch, the Common Rampichino, the Black Redstart, the Collared Dove, the Buzzard, the Wood Pigeon, the Domestic Pigeon, the Hooded Crow, the Magpie and the Jay.
In conclusion, therefore, it is emphasized that these data do nothing but testify how the winter season, characterized by abundant rainfall and temperatures above the norm, has favored the stop of several individuals who, like every year, find, in the territory of the Arosian station, the ideal environment useful for their survival.
