Walet dalam Jaring.
The 20 cm long Hirundo rustico or barn swallows are recorded as the farthest to wander. They fly across continents from Africa, Asia all the way to Australia. During the journey, they use sun as navigation so that they never get lost. According to Prof Dr Johan Iskandar Msc, barn swallows have magnetic compass in their bodies that functions to find their flying direction. Furthermore, the birds are gifted with special memory―can well remember places they have passed-in fact, they can choose the efficient and safe routes
Walet dimakan ? disantap?
Mungkin saatnya walet menuju kepunahan, baru harga sarang bakal naik lagi...
