BIRD FEEDERS, IN THE FOCUS!

In winter, feeding the birds that visit our gardens, balconies and terraces is a good way to help them to overcome the coldest months of the year, which are the more energetically demanding as well.

In several countries: the United States, the United Kingdom and Australia, about half of the households keep active feeders and, only in the UK, the amount of food destined for this activity is believed to be enough to feed 196 million birds. Given these figures, it is not difficult to imagine that its ecological impact on bird populations is huge, both positive and negative.

Researchers from the British Trust for Ornithology (BTO) have discovered, from the data obtained through garden monitoring projects, that the diversity of birds that visit these gardens has tripled in the last 40 years, for example. On the other hand, some species, such as Blackcap or Anna's hummingbird, have modified their migratory strategies by becoming regular wintering birds in the UK and Canada, respectively.

So far we have exposed the positive effects of the proliferation of feeders in the gardens of some countries, but what about the negatives? In the aforementioned study it has also been seen that feeders are a perfect tool for disease transmission. Moreover, it is known that the decline of the Common greenfinch population in the United Kingdom between 2006 and 2016 - when it plummeted from 4.3 to 1.5 million birds - was directly related to this fact.

In conclusion, feeders in winter yes, but as clean as can be!
