22nd September

The three chicks are still returning to the nest box, but are likely to move away over the next week or so.  the eldest chick is 11 weeks old tomorrow, and just shows how long Barn Owls take to fledge.

16th September update

The chicks are now 9 weeks old and look like adult Barn Owls.  They currently spend most of the time in the entrance to the box, out of view of the camera.  However wild windy conditions today persuaded them to go to the back of the box - there's no point waiting for their parents to come back with food in daytime with strong winds.  The weather forecast for this week is certainly not very good for owls and we can only hope that enough food will be brought back fro these to survive.  Just up the road from this box is another box where the eggs are hatching and this moring there were five tiny chicks and one egg........these will be very lucky to survive as they will not fledge until end of November.

29th August - growing well

The three chicks are now 6-7 weeks old and are now looking more like Barn Owls than the 'balls of fluff' earlier.   They are also much more mobile and often wander to the front section of the nestbox out of camera view.    The good long range weather forecast and the fact that prey is plentiful during periods of harvesting local wheatfields gives a promising prognosis for these youngsters.    Other Barn Owls in the area are doing much better than we thought possible at the start of the season.

11th August - ringing visit

The three chicks were ringed this morning where it was found that they are all females.  They were very fat, and are obviously being well fed.  Chicks can be aged according to how much of the wing feathers are unfurled out of their quills.  Measurements suggest that the chicks were 37, 33 and 28 days old, whereas we know that they are actually 35,29 and 26 days old, so they are developing slightly quicker than normal.  This may be down to the amiount of prey available.  There are six more pairs of Barn Owls in the same area as this box, so this area has not been too badly affected by the prolonged winter.

16th July - third chick

The third chick arrived at 07:00 this morning 16th July.  This will be the chick from the fourth egg with the second egg failing to hatch.   This CCTV is providing some interesting facts - the eggs being laid at regular intervals of three days (wheras it's normally two days) and the eggs are hatching uniformly at 31.5 days.

13th July - second chick

The second chick emerged from the egg at 07:00 on 13th July.  This is likely to be the third egg that has hatched and the second egg has failed.
