We are now living less than 5 minutes away from what most people describe as being the center of the city, the Plaza de Catalunya. Posh hotels, Hard Rock Cafe, couple of big fountains and weird sculptures. And lots and lots of pigeons, expecting to being fed by the occasional tourist. And they’re lucky, as the tourists come here in their millions.
This said, as in most big european towns, pigeons are considered a nuisance or a plague. The municipality of Barcelona does not kill them, but chemically neuters 20.00 of them every year. Does it work? Not really, not on Plaza Cataluny anyway.
