Food delivery at 8:13.

Based on all of the data that I have, egg 3 should arrive between 2:30 am and 11:00 am Wednesday. Using only numbers for the current female, that narrows to 2:30 am to 6:30 am.

Landing is a bit tricky when the breeze blows towards the box.

Egg number three arrived at 3:11 a.m.

We now have three eggs. A fourth egg is possible but this female has not laid a fourth egg in previous years.

This was an unusual interaction. The male arrived to take over incubation but the female didn't leave. After 36 min on the edge of the box, she got back on the eggs.

The condition of one egg is concerning me. It looks as though it is damaged.

A very early changeover at 3:31. Note the egg nearest to the camera. This is the one that is probably not viable. It is moved very easily, suggesting that the contents have dried out.

We have to wait and see whether the damaged gets knocked to one side and ignored or whether the birds eat the shell.

Wakefield's first female peregrine fledged 29 chicks in eight seasons, i.e. an average of 3.6. Our present female has fledged three chicks in three seasons, giving an average of 1.0.

Egg 4 being laid at 11:39. Watch closely.

We now have four eggs. Counting 34 days from the laying of the third egg gets us to Tuesday, 28th April. This is approximately when we expect hatching to start. One egg appears to be damaged and that number could increase if the female carries on being as clumsy as in this clip.

First changeover of the day.
