New update by the ringing station of thePonza Island: “Yesterday we recorded another special recapture. This time it was a Swallow (Hirundo rustica) that it had already been ringed in Norway, whose body responsible for ringing is the Stavanger Museum. It is probably Norway to which he is flying again, to return there for there breeding season.
As is well known, birds and animals in general do not know borders, only geographical and topographical barriers if anything. However many of them have evolved to overcome them, such as long-range migratory birds such as the Swallow, which cross the Sahara Desert and the Mediterranean Sea before reaching the distant goal they set for themselves. These days the activity is fairly quiet, with average catches of around 200-300 birds per day, quite constant.
There are no peculiarities to report: no extraordinary species or exorbitant numbers, therefore. The weather is mostly clear and sunny. May is often the month when the days of 'blow', i.e. extraordinary numbers of catches, occur more frequently and more likely, so we continue our business ready for exceptional days!
