Once again, the house sparrow and the chaffinch (pictured) are running a neck-and-neck race to see which is the most common bird in the gardens of Flanders, following last week’s volunteer census organised by Natuurpunt. The organisation asked members of the public to spend half an hour on Saturday and Sunday counting the number of birds in their garden, noting the species where possible. About 3,000 people have reported back so far, with more to come.
