Since the installation of the webcam in 2016 we have been able to monitor the progress of the adults and their clutch. This has enabled us to compile data on the egg laying and hatching dates, and the number of days from the laying of the penultimate egg to first hatching. These observations provide invaluable insight into the breeding ecology of the Wakefield peregrines.
The information gathered for the 2016 and 2017 breeding seasons shows the eggs were laid within a 1-day window. However, in 2018 the eggs were laid around 10 days later. The exact reason for this is unknown, but a theory is that the female was put off entering the nestbox by the sight of the new webcam that had been installed which was white. The webcam was covered in dark tape and the female entered the nestbox shortly afterwards.
Normal peregrine clutches are three or four eggs, with two or three hatching. The data below is the breeding record for the Wakefield Peregrines since 2015.
On 14 June 2018 a young juvenile peregrine (ringed TAA) fell from a nest high in the KC Stadium at Hull. He could not be returned to a place near the nest, so a
decision was taken to re-home him. After consultation with the relevant parties involved in the rescue, it was decided that Wakefield Peregrine Project could take on an extra chick. Natural England gave the necessary permission for the action, and TAA was put on the walkway at the top of the tower, close to the nestbox. TAA successfully fledged, along with the three juveniles.
