3rd April....Female (left) begging food from the Male (right). Note the horizontal pencil line some 75mm up the left hand side of the box. As the nest is constructed it provides a good idea of how deep the structure is.
4th April...Moss and some grass is brought in daily now. Up to 100 visits by the female (who does the majority of the building) during daylight hours. The box is abandoned during the night.
7th April...The nest cup is now forming although the floor of the box is still visible.
9th April...Male feeding the female a small grub. She called and called until he came into the box with food.
21st April...Nest structure is now lined with grass, then feathers and fleece or wool. Note the 75mm line has almost disappeared. The Female has been roosting in the box from 5 minutes before sunset each day since Good Friday. Her feathers are puffed up against the cold and her head is tucked round under her wing.
22nd April...The first sign of eggs. They are usually laid early in the morning then covered with wool and feathers. One egg is usually laid each day so you would expect the first one to have been laid on Easter Monday. A clutch of eight or more is expected then incubation will begin.
28th April...The clearest view so far of the eggs. At least eight are visible. This picture was taken at 7am just after the female left the nest. The box remains empty for most of the day with just small amounts of wool or feathers brought in occasionally. The male can be heard calling around his territory throughout the day and the female begging to be fed. The feeding usually takes place in a nearby tree or hedge under cover.
Tues 29th...Nine eggs this morning. The clutch is almost if not complete

Weds 30th...No more eggs have been laid today. The male is now feeding the female inside the box more frequently and she is sitting regularly. Incubation has probably started.

Weds 30th...A typical picture of the female incubating the clutch. She is awake and quite twitchy, frequently scratching, fiddling with the nest material and turning the eggs with her head.
