cordwood nestboxes 2012

Blue tit eggs
The 2012 breeding season was the first year for siting nestboxes at Cordwood.

The year was notable because:
  • our drought that had begun in February 2011 continued until May 2102 and was immediately followed by the wettest summer on record;
  • ground & tree clearance and building work in 2012 inevitably impacted on wildlife.
So, an unusual year in which to begin siting a total of seventeen nestboxes:
  • Twelve small nest boxes with entrance holes of various diameters - nine occupied by great, blue and coal tits
  • One small box with an open front - unoccupied
  • One medium box with an open front - unoccupied
  • Two kettles with lids removed - one occupied by robins with two broods being taken
Two of the boxes were damaged by grey squirrels and a further two boxes were damaged by greater spotted woodpeckers.

·      Robins occupied one kettle and raised two broods (av. brood size not determined).
Only one nest inspection undertaken in May 2012.
Next year, more nestboxes of different kinds will be added to increase diversity of birds using them. I also hope to do more than one nestbox inspection and may even be able to encourage friendly birdringers to come along and ring fledglings. 
Of course, I'll use EpiCollect to collect data and geotag nestbox locations.
