I'm pleased to say that the diary for 2019 has been successfully completed. It has been a pretty good year too, with a total of 17 chicks fledging from two nest boxes. As usual, no birds took any interest in Box3! The only unexplained happening in the year was that the 11 seemingly healthy chicks that were in Box2 before I went on holiday in early May, had been reduced to 8 chicks by the time I got home a week later.
I still have most of the data from last year, so you never know, I might be able to add a bit more to the 2018 record. That year was an unusual one in that the chicks in Box1 fledged at about the same time as the eggs in Box2 hatched! Such a wide difference in timing is very unusual.
As regular readers of this web site will know, this is a diary of the breeding behaviour of blue (and occasionally great) tits in our garden in Mayford, Surrey since February 2001. New readers can read a summary of what has happened in previous years by looking at the Overview page which gives the dates of the principal events, such as the start of nest building, egg laying, hatching and fledging, and the important statistics, such as how many eggs were laid, hatched and fledged. Each year has its own Summary page which gives more details about that year's events.
In 2013, 2015 and 2016, two females laid their eggs into one nest, laying a total of 21 eggs in 2013, 18 eggs in 2015 and 17 in 2016. To watch the two hens co-operating with incubating and feeding the chicks was a great privilege - we did not realise such things happened!

This is the last chick leaving Box1. This year the chicks from both boxes have fledged earlier than usual. Box2's chicks fledged on 18th May - a bluetit record. The last chick from Box1 shown here is the earliest second box too. A total of 17 chicks fledged successfully - 9 from Box1 and 8 from Box2.
We will never know why the number of chicks in Box2 dropped from 11 to 8 while I was away on holiday, but at least there were no more disappearances.
