...because it is nesting under the windowsill of the M&P office in Hanover.
Our colleague Till Gorgs managed to capture them on a short video.
The curious tits are cavity-nesting birds which, in addition to their original tree and woodpecker cavities, mainly use nesting boxes on trees for breeding. Occasionally they also look for nesting opportunities in cracks in walls, under roof tiles, under flat roofs or in other cavities on buildings - sometimes even in letterboxes or watering cans!
Blue tits usually only breed once a year, but have very large clutches of up to 14 eggs and a correspondingly high food requirement for the hungry brood. They fledge after about 2 weeks, but are still dependent on their parents' feeding for a long time.
The blue tit (Cyanistes caeruleus) reaches a size of twelve centimetres and a weight of ten grams. This makes it just half the size of a sparrow. Despite their modest size, blue tits are very self-confident birds. They loudly defend their feeding places against other bird species and often even chase them away. If they are not killed as young by larger birds or voracious mammals such as martens, blue tits can live for up to five years.
More information about the blue tit can also be found on the website of the nature conservation organisation NABU: https://www.nabu.de/tiere-und-pflanzen/voegel/portraets/blaumeise/
It's nice that animals also feel at home with us 🙂
