11 May: First week with Otto

This aerial photo shows the first weeks data on the movements of the gander Otto, caught at Valsted Enge 3 May. We only track ganders with satellite transmitters because North American studies back from the 1980s had found that females deployd with radio transmitters failed to breed. Perhaps bacause the antanna interferes with the birds mating behaviour.  
Otto is named after Otto Friedrich Müller (1730-1784), Danish zoologist who in his Zoologiae Danicae Prodromus in 1776 descibed the light-bellied brent goose as being different from the dark-bellied brent goose that Carl von Linné had descibed in 1758.
