Great Tit researchers Lysanne Snijders and Lies Zandberg of the Behavioural Ecology Group and NIOO-KNAW write together with Peter de Vries of NIOO-KNAW a blog on the website ‘Beleef de Lente’.

Now the breeding season is about to start again, Lysanne and Lies keep you updated in the coming months via their blog about their experiences and adventures with The Great Tit. Together with the blog, from March 1 also the cameras of the ‘vogelbescherming’ will be activated again, so that you can also follow the great tit from home.

New publication: Neighbouring birds sing 'out of tune'


Last week, also a new article was published by Lysanne Snijders entitled ‘Song Trait Similarity in Great Tits Varies with Social Structure‘. Great tits are territorial and use their song to signal their territory to unfamiliar potential competitors and familiar neighbours. The study of Lysanne shows that great tit neighbours more often differ in the rate that they sing their songs (songs per minute) than great tits that are not neighbours. This, according to the researchers can have two causes: either neighbouring birds sing actively different to prevent confusion, or the difference is due to a preference for certain neighbours while picking out a territory. The authors conclude that great tit neighbourhood structure is likely to be a relevant in shaping variation in territorial birdsong.
