A study on how different species of migratory nightjars organize themselves across the annual cycle in relation to latitudinal and environmental gradients. By Aaron Skinner Background For nearly two centuries, biologists have been fascinated by a simple but surprisingly powerful pattern in nature: animals tend to be larger in colder places. This idea, kn

Ramde Bhatiya The Global Nightjar Network (GNN) steering committee, together with the Kshitij Foundation, is pleased to announce the results of the first Manish Mehta Microgrant for Nocturnal Avian Ecology Research and Awareness. We received 15 applications and had a difficult time choosing among them. This is an exciting sign of how many dedicated researchers and educators are bringing atte

Photo: Ervín Hrtan A study on how white patches convey the quality of male European Nightjars By Richard Schnürmacher Many avian species sport bright, contrasting colours, but what about the birds active at night? Variation in the white markings of adult male European Nightjars suggests sexual selection on their size. Age and body condition strongly influence how big

Birds with GPS-trackers reveal their site-fidelity across the annual cycle Nightjars regularly revisit the location where they have bred and wintered Migration routes are mo
