Last year we used a caged feeder on an old table outside the kitchen window, and as this is only accessible to bluetits, we are using it again now. Today Barney and Fluffy appeared on the cotoneaster by the study window, so Elizabeth went immediately to collect some mealworms to put into this exclusive feeder. By the time she went outside they were in the nearby hedge, waiting for her - and this is round the corner from where they first saw her!
Later in the day, when she had been away for some time, she took some mealworms out, and called "Fluffy, Fluffy" - and both the birds arrived within a few seconds.
