Over the last week we have been doing a little project to determine what happens with our tree sparrow population throughout the year.

To this end we have been ringing the young Tree Sparrows in the nest box.

This may look a bit disruptive to the new chicks but they are only out the nest for a couple of minutes and the parents are straight back looking after them once returned to the nest.

The pictures below show a newly fledged youngster showing their sparkly new ring.

We will now monitor over time and see if they remain at Clarks bog or spread out into the local area.
