Thijs Fijen is, by his own admission, a fanatic birdwatcher. For years he has been visiting various sites in the Netherlands – heathlands, dunes, dikes, forest edges – to observe and count migrating birds. During those visits, well before he became a pollinator researcher at Wageningen University, Fijen and other observers would also count the bumble bees that passed through the Dutch countryside.
