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.

26th July update

We still have three chicks in the barn owl box, and we can assume that the second and the last egg were the ones that failed to hatch using the details below:-

egg date  & time	chick hatch	difference
05/06 @ 21:15	07/07 @ 11:30	31d 14h
08/06 @ 19:30	not hatched
11/06 @ 20:00	13/07 @ 07:00	31d 11h
14/06 @ 11:00	16/07 @ 07:00	31d 20h
17/06 @ 11:00	not hatched

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.

7th July - First chick

The first egg hatched today at 1130, which is approximately 31.5 days after being laid.   After a very poor start to the breeding season in the county, quite a few Barn Owls in Lincolnshire are now on eggs or very small chicks.

Fifth egg - 17th June 2013

The fifth egg appeared at 11:00am on Monday 17th June
