I have never photographed swallows feeding chicks until now. There are many swallows in Greece, much more, than in Hungary. I don't know what is the reason, but I suppose swallow nests are in more safety in Greece, because people don't destroy them. One of these little birdies eat 1000 mosquitoes per day. Millions of them eat tons of mosquitoes per year, that's why we must save them!
