Young, naïve starlings are looking for their wintering grounds independently of experienced conspecifics. Starlings are highly social birds throughout the year, but this does not mean that they copy the migration route from each other. By revisiting a classic ‘displacement’ experiment and by adding new data, a team of researchers at the Netherlands Institute of Ecology (NIOO-KNAW) and the Swiss Ornithological Institute (Vogelwarte Sempach) have settled a long-lasting debate. Their findings are now published in the scientific journal Biology Letters.

An international team of scientists has examined the long-term effects of fireworks on wild birds.

The reproductive tracts of males and females contain whole communities of micro-organisms. These microbes can have considerable impact on (animal) fertility and reproduction, as shown by Melissah Rowe from the NIOO-KNAW.

Northern lapwings are easy to spot during the breeding season, with their noisy aerial acrobatics. But as research led by the Netherlands Institute of Ecology (NIOO-KNAW) shows, lapwings that breed virtually next to each other in spring may spend their winters thousands of kilometres apart. As a survival strategy, it's not enough to stop the species' ongoing decline.

An oystercatcher nest is washed away in a storm surge. Australian passerine birds die during a heatwave. A late frost in their breeding area kills off a group of American cliff swallows. Small tragedies that may seem unrelated, but point to the underlying long-term impact of extreme climatic events. In the special June issue of Philosophical Transactions of the Royal Society B, NIOO researchers launch a new approach to these 'extreme' studies.

Songbirds change their behaviour and timing when nestboxes are exposed to artificial light at night. "They become light sleepers, literally and metaphorically", says Maaike de Jong (NIOO-KNAW). She successfully defended her thesis on the effects of different colours of light at Wageningen University on Friday. The most surprising effect she's found? Some birds are forced to become more monogamous...

The great tit has revealed its genetic code, offering new insight into how species adapt to a changing planet. Initial findings suggest that epigenetics – what’s on rather than what’s in the gene – may have played a key role in the evolution of the ability to learn. And not just that of birds...
