Birdfeeders in our Glasgow garden were swarming with Blue tits until mid-May, but since then none! Where have they gone, and why?
They have gone about 20 mins down the motorway to my garden, why? Because they chose to nest in my trees Joking aside John they will have been nesting and raising their chicks and they may have chose to nest somewhere well beyond your garden thats all. I am sure they will be back soon once the young has all fledged and they need some easy to find food .
Bluetits Diet
During summer, their diet comprises mainly of small insects, caterpillars, spiders and invertebrates such as millipedes. In urban and rural areas, they will continue to feed in gardens where food is provided. In the spring they will also feed on tree buds, often causing damage to fruit trees.
