In the table below, the first 20 boxes are those erected by the bird-ringers and are of the small-hole type. They are located along Wey Top Path in Wey Wood.
Boxes 21 and 22 are examples of the open-fronted type of nestbox and are located behind a former workshop in the old farmyard. There are a number of this type of box around the farm and, to date, none of them have ever been taken up by any type of bird.
Boxes 23 to 31 are again of the small-hole type and are positioned along Wey Top Path in Wey Wood.
Those with the prefix X were put up by Brian Lavers, a Countryside Restoration Trust volunteer with both the conservation and monitoring groups at the farm. With the exception of X11 (located near the old farmyard), these boxes are to be found south of the Tankersford Wood permissive footpath.
The ten boxes with Roman numerals are all fixed high up on the north-facing side of the new dairy building. This is their first appearance in the annual summary.
The “barn owl box”, the “stock dove box”, the “river box” and the “little owl box” are purpose-made large-hole type boxes and are located in the area of Wey Wood.
In 2012, the names of the ringers were not recorded and the column is empty.

The Totals row refers to the number of ringed pulli (young birds who cannot yet fly).
Commenting on the low numbers in 2012, David Ross says, “It has been a pretty bad year all round. Last year I ringed 421 pulli, this year only 280 — and that incudes pulli from 20 new boxes in a local wood. It wasn’t that the boxes weren’t taken, they seemed to be abandoned with lots of dead young or cold eggs. The ringing secretary for Surrey bird club has found the same thing, a shortage of young birds.”
Brian Lavers adds, “The tits time their egg hatching to coincide with the appearance of caterpillars with which to feed their young, especially the caterpillars in oak trees. This year was one of those when it all went disastrously wrong due to the very wet April.”
The survey of nest boxes took place on 17th May this year and on 21st May in 2011 and 2010.
