The bill-clatterers are currently occupying nests atop old factory chimneys, church towers and other prominent vantage spots, often in the middle of villages, towns and cities. They are perfectly safe up there. Humans don't interfere with them because, as we all know, from time to time they bring along human babies. Less well-known is their legendary ability to tell the future.
White Storks always nest within a short flight of meadowlands, marshlands or riverbanks. These are their preferred habits for stalking around on long legs and prodding with long beaks for small mammals, large insects, lizards, snakes, frogs and fish.
Widespread environmental destruction and use of pesticides have caused the collapse of stork populations in some parts of Europe over the past half century. Mercifully, they are still fairly plentiful in the Algarve all year round.
For the next few months they will be concentrating on raising families (like this couple atop a Silves supermarket). Mature adults are now adding sticks to the same nests they used last year and the year before. The males will stay on the great big bundle of sticks most of the time, only leaving to feed. The females will lay four eggs this month or next. Both parents will take in turn to incubate, with much bill-clattering at changeover times.
