The trials of the Common Swift - bird of the year in the Czech Rep
Over the last couple of days we've seen one of the first signs of autumn here in Prague, as swifts have started gathering for their annual migration to the south. But for how much longer will this annual ritual continue? The common swift has been chosen this year by the Czech Ornithological Society to be the subject of its annual Bird of the Year campaign to heighten a growing threat to the swift's traditional habitats.
The swift is no stranger to Czech cities, as the breed favours nesting under the eaves of apartment buildings or even within building themselves. Pavel Vasak is from the Czech Ornithological Society. He explains how the bird developed new habits in reaction to changing trends.
"After 1989 the majority of cities in the Czech Republic - especially Prague - began seeing extensive reconstruction of old buildings in very poor shape. The repairs of facades and roofs, however, meant that the birds' nesting choices eventually grew limited, which eventually influenced the species to begin nesting in ventilation shafts in pre-fabricated apartments. Today, that has proven to be a bad choice."
Setting up home within ventilation shafts is a habit that has now put the birds at threat. There have been many cases of birds being holed up, trapped inside ventilation shafts with access routes cut off.
The danger to the swift is one reason the Ornithological Society chose the bird for its 2004 campaign in the first place, and in part thanks to the campaign the society along with the Ministry for Regional Development, City Hall, and members of the concerned public, have been able to put pressure on construction firms to respect the birds' habitat, and rebuild in such a manner as not to put the species at continued threat. Pavel Vasak again:
"In past years our experience with construction companies was not that positive. But since last year we began co-operating with the Ministry for Regional Development and City Hall - that has made the difference. Construction firms - and the public - are now more aware of the needs of the swift and what needs to be done - and can be done - to help the bird's habitat survive."
In primeval times swifts used to nest in cracks and crannies on the sides of natural cliffs but their choosing man-made structures for nesting goes back to ancient times too - to the first stone structures and villages ever built by man. That set-up proved successful for millennia: the Czech Ornithological Society will do every thing within its power to makes sure that set-up continues.
