Spring storking


Latvia is colloquially called the Land of the Storks. The country has six times the number of nesting storks than anywhere else in Western Europe. Reasons for this are not entirely understood and based more on speculation than research from what I’ve read. Perhaps it’s just that the Latvian landscape is so stunning – who wouldn’t want to be surrounded by such spectacular scenery being a new parent? 

Ok, so seriously, this bird prefers wetlands and marsh areas for its prolific diet of frogs and insects of which Latvia still has plenty – bogs and bugs. One theory about why the country now has so many white storks is that after the Ukrainian Chernobyl disaster in 1986 they were forced to find other places to breed after their natural habitat was destroyed. Hence all Baltic States being the beneficiaries of the blessings these birds are supposed to bring.

Around 10,000 white storks fly from West Africa to Latvia every year, arriving during April to set up nest. And when I say nest, I mean something like you see on a Flintstones cartoon containing pterodactyls. Measuring around six feet deep (1.8 metres), nine feet wide (2.7 metres) and weighing up to 250 kilograms, this is not a small feat. Males collect building material such as sticks and the female places them…nothing wrong with being house proud, ladies.

In the bigger nest, smaller birds make their homes tucked in the branches – an ornithologist’s heaven. In the countryside you see nests on top of farm house roofs, church spires and wooden stands erected specifically for nesting purposes. And, of course, the chimney, which is where the saying comes from that storks bring new babies. Also, this type of stork is known to be a monogamous mater and each year breeding couples return to the same nest. It’s not uncommon to see one bird minus previous mate spending a solo season in Latvia. They lay between two to six pale coloured eggs then head south again in August after their young are able to fly, fending off the bitter winter months.

When winging back to Chad or Niger from Latvia they take a journey through Romania, onto the Bosporus to the Gulf of Suez and through the Nile Valley before reaching their final destination. At around 4500 kilometres, the journey takes one and a half months.

They are seen as harbingers of good luck and prosperity so it’s no surprise their presence here every spring is enthusiastically welcomed. It’s a sign winter has gone and warmer weather has arrived. Time to make some babies!
