These studies produced an outpouring of publications in several scientific journals, largely on social factors influencing breeding behaviour in insects and seabirds, but also on insect migration in the Pyrenees and behaviour of the western sandpiper Ereunetes mauri and the willow warbler Phylloscopus trochilus
in continuous daylight.
