Note 1.  After the first 8 eggs had been laid, a fight over possession of the nest took place.  Fresh nesting material was brought in and nearly 3 weeks later the new hen started laying.  By the time that a further 3 eggs had been laid the original clutch had resurfaced and she probably thought she had laid all 11!  Six eggs eventually hatched and five chicks fledged.

Note 2.  Three chicks were taken from the nest box by a great spotted woodpecker shortly before they fledged.

Note 3. The female disappeared shortly after she had completed the nest.  The male continued to call her and bring food to the nest for her for over two weeks.

Note 4.  A great tit pair occupied Box1 these years.  Incubation and fledging times differ little from those of bluetits.

Note 5. Three days after hatching, all the chicks in this box were dead.  How they died is not known for certain, but is believed to be due to lack of food..

Note 6.  This nest was deserted for unknown reasons early on 1st May.

Note 7.  This nest was started by a bluetit but deserted before the nest was completed or eggs laid.  The nest box was subsequently taken over by a great tit who started adding more material on 7th May.  The rest of the dates relate to the great tit's occupancy.

Note 8.  After a couple of days, the male great tit seemed to lose interest in bringing food to the nest.  He only visited infrequently and on the third day the chicks started dying.  By the morning of the fifth day, all the chicks were dead.

Note 9.  The male bluetit disappeared during egg laying and only 3 of the 10 eggs hatched.  The female managed to bring these chicks to a successful fledging by herself. 

Note 10.   The female disappeared shortly after being fed by her partner at 11.30am on Saturday 17th April, the day after she laid her first egg.  The male continued to visit the nest box once each day for several days.  We fear the female must have been predated.

Note 11.  Two females laid eggs in this nest box and then competed to see which would incubate the eggs.  Amy won that competition!

Note 12.  At the time we would have expected the bluetit pair interested in this box to have started building a nest, our next door neighbour was building a car port the other side of the hedge and only a few feet away from the nest box.  This may have contributed to the lack of a nest being built in Box3 this year.

Note 13.  The very cold early Spring meant that the nests in both Box1 and Box2 were started in a very haphazard way.  1st April was around the right date for both.

Note 14.  Two females shared this nest box.  Sally laid 11 eggs and Scruff laid about 10 making about 21 in total.  The first egg was laid by Sally on 23rd April and Scruff's first egg was laid on 1st May.  They both laid eggs for 3 days before Sally stopped laying.

Note 15.  The use of the next door neighbour's car port  was sufficiently disturbing to put birds off using Box3 again this year.  We shall have to find a new location for this box in 2014

Note 16.  The female parent disappeared sometime during the afternoon of 25th May.  Without the female to keep them warm overnight, the chicks all died.

Note 17.  Some time last December a bluetit roosted in this box for several days.  This was sufficient excuse not to move the box this year.  However, the bluetit stopped roosting and again no nest was built.

Note 18.  Three days after they had hatched out, Georgie's chicks started dying.  One the first day, one a couple of days later and by five days later they were all dead.  No clues at to the cause of this have been forthcoming.

Note 19.  As in 2013 (see Note 14) two females shared this nest box.  Suzie and Rosie started laying on the same day and the number of eggs increased by 2 each day until the total was 18.  They then both stopped laying.

Note 20.  What happened to the chicks in this box is a mystery.  Perhaps the female was predated and the male could not manage to look after them by himself.  Perhaps they caught some bug or other - who can tell.  All we know is that it is another failure to add to the already extensive catalogue of failures in Box3!

Note 21.  Patch, the male bluetit in Box1, was last seen on 24th May, the day the last egg in this box was laid.  Whether he was predated or just decided he wasn't interested is not known.  His disappearance meant certain death for the chicks.
