I had expected it to be a House Sparrow or Blue Tit not ......

...... a Magpie.
It did its best to get its head through the bars but left empty beaked.
As far as I could tell it was the only visitor.
There were no beak marks in any of the jars of peanut butter.
Early days yet. It had only been up for a few hours.
The bird table has had lots of activity, mainly House Sparrows, Starlings and Blue Tits.
An occasional visitor is a Coal Tit.

As is usual at this time of year the Coal Tit will take black Sunflower seeds and hide them in the ground or in a crevice in a tree trunk. I have watched them do both in previous Winters.
