Fourth (and final?) egg laid

NTU's resident falcons laid their fourth egg on Monday 21 March. Will it be their final one?

A fourth egg was laid on Monday 21 March. This will most likely be the last one, though it is not impossible for peregrines to lay five – in 2014, a pair in Staffordshire successfully raised five young!

As explained in the last post, the first egg was laid on 14 March at around 2 am. There was then a wait of around 56 hours until the second one was laid, which arrived on 16 March at around 10.30 am. The third egg was laid on 18 March at 9.30 pm, 59 hours after the second, and finally the fourth egg was laid on 21 March at around 1 pm, 63 hours after the third. That's 178 hours between the first and fourth egg!

The adults will now incubate the eggs almost continuously until the chicks hatch. Last year the first egg was laid on 14 March and the first egg hatched on 21 April, so we have around four weeks until we get to see the chicks. Until then, we get to enjoy the sight of the adult birds and the occasional prey item being brought in (and probably not a lot else!).

We will keep you posted on any further developments with the birds over the coming weeks.
