Winter Barn Owl Box Checks – A Helpful Reminder

If you’re lucky enough to host a Barn Owl box, we’re coming up to the perfect time of year to give it a winter clean and a quick health check. December and January are ideal months.  A little attention now can make all the difference for the Owls when the breeding season returns.

When to do it:

Choose a calm, dry day. If you can, aim for late afternoon — by then the resident owl will usually be waking up and preparing to head out to hunt, which helps minimise disturbance.

Before you go up the ladder:

Before any cleaning takes place, check the box from the ground and once again up the ladder, ensure the ladder is stable and footed by another person, and confirm the box is firmly secure before starting to clean it out,

Approaching the box:

Move in quietly and with care. Remember that something may be inside, and not always a Barn Owl, so never put your head into the entrance hole or inspection hatch. Gloves and a mask are essential — years of pellets, dust and debris can be very unpleasant, and especially so if the box has hosted Jackdaws.  If the old nest material is compacted, be prepared to gently scrape it loose.

Cleaning out:

Remove most of the old debris but always leave a couple of inches on the bottom. This acts as a natural nest base. Don’t use any pesticides, disinfectants or chemical treatments. If you’ve had to clear the box right down to the floor, add a layer of untreated wood chips so the Owls have a suitable surface for laying.  Top tip for the person footing the ladder - hood up, look down and mouth shut!  You might get a surprise ‘nest confetti shower’!

Maintenance check:

While you’re up there, give the box a quick inspection for any wear, damage or loosened fixings. A simple repair now can prevent bigger problems later.

If you have questions, need advice, or would like help with repairs, please do get in touch with us — we’re always happy to help keep Suffolk’s Barn Owls safe and comfortable.
