For most of us, the range of winged animals we see in a day is rather limited. Maybe an inbound flutter of a pigeon heading directly towards you, the piercing squawk of a seagull over the city or a muddle of mischievous magpies. If we extend that array of sightings to a year, then the number of species we see probably only jump up by around 10 or so and that’s if we’re lucky enough to cram a few holidays in. Or is that the case? Are we just blind to the extent of sky life around us?  If you’re Arjan Dwarshuis, you’d agree with the latter. There are currently around 10700 recognised species of birds across the entire world. In a single year Dwarshuis spotted almost two thirds of those species’ in a dedicated swoop of the world that was mapped across 40 different countries. Arjan set the new world record with this effort in 2016. Being a world record holder is quite a title, but what’s more impressive, we believe, is the reason behind Arjan’s hobby turned vocation.
