I have been writing a short piece in the Grantham Canal Society newsletter each month for the last three years – I thought it would be fun to share these little snippets on here!

January 2018 – Long tailed tits
A walk down the towpath in January is likely to be accompanied by the flutter of wings and warning calls as birds forage in the path-side hedgerows. One of the smallest species in the UK is likely to be among them, but far from being discreet they make their presence disproportionately known as they forage.
Long tailed tits, weighing just 9g, are highly social birds – they move through the landscape in flocks of closely related individuals, maintaining a shrill ‘si-si-si’ call-and-response as individuals keep in touch. Their aim, at this time of year especially, is to forage for enough high-value food to keep their tiny bodies warm enough to survive. They seek invertebrate prey by preference, capitalising on their low weight to pick food such as moth eggs as well as other invertebrates from the higher reaches of twigs and leaves which their heavier counterparts are unable to reach.
At night, the flock remains together, nestling down in a shrub or tree to form a dense ball with just their tails sticking out. As spring marches on, they will be building their tiny nests out of moss, lichen and spiders webs, lined with feathers. Interestingly, they are also social at nesting time – they will try to pair up and nest on their own but if unsuccessful, they will help at the nest of a close relative.
Listen out as you walk this winter – the distinctive call will alert you to the presence of these charming little ‘flying teaspoons’!
