A peregrine chick has been spotted in the nest on the clock tower of City Hall Cardiff. It appears that there is only one chick this year but after last year's breeding failure this is great news.
It was Valentine's Day for Peregrines too
Valentine’s Day is traditionally the day when birds start to pair up and our Clock Tower Peregrines seem to be no exception.
Thursday the 12th of February saw Mrs Peregrine (the bigger of the two birds) clearing out a possible nest site very high up on the tower. Although we could only see her back and tail feathers, it was clear she was busy, as leafs and small twigs were spirally down behind her, occasionally hitting Mr Peregrine who was perched nearby, maybe overseeing operations.
Friday the 13th saw more action as Mr P left the Tower in a swift hunting flight mid-afternoon. He was soon back with a Valentine’s Day meal of Pigeon for the female. Offering dinner to your partner works for Peregrines as well as humans! She didn’t wait for Saturday the 14th though and after a plucking the prey in a shower of feathers, tucked into her meal without any courtship ceremony.
They are often on the tower together now, and I think it won’t be long before they make their choice of nest site and start carrying a few new sticks in to build it up.

The nest of Peregrine falcons in the clock tower appears to have failed, due to unknown causes sometime during the last week or so. However, after an absence of several days, both birds are showing renewed interest in the nest-site. Today has seen considerable activity with one bird visiting the nest several times and apparently busying itself tidying the interior while the other bird of the pair watched from close by. Although peregrines only have one brood each year, if the first brood is lost at an early stage they sometimes re-lay a second clutch, either in the original nest, or perhaps more often, at a nearby site. We now watch, wait and hope that a new clutch of eggs will be laid sometime in the near future and that these magnificent falcons will have more success the second time around.
It now looks that the breeding attempt by Peregrine Falcons in the clock tower has failed. All indications were that eggs were laid during late March and early April and if all had gone according to plan, they should have been hatching about now (eggs are usually incubated for 31-33 days). Unfortunately, no birds have been seen at the nest or perched nearby on the clock tower for several days now so it seems certain that the nest has been abandoned. We do not know why this breeding attempt has failed but the most likely cause is that the eggs have been eaten by predators, perhaps crows, ravens or gulls. Although peregrines only raise one brood each year it remains possible that the birds will make a second attempt to breed and we remain vigilant in case that happens.
The Peregrines are back on the City Hall Clock Tower. One bird seems to be spending most of the day hidden in the recesses of the nest (on the right hand side of the ledge underneath the clock face), suggesting that she may have started incubating eggs. This would imply a laying date a little earlier than we have seen in previous years. However, we are aware of another local pair of peregrines that are incubating eggs, so perhaps it is an early season this year. Museum Curator Adrian Plant has taken over the duties of the Peregrine Web-cam, and will be keeping an eye on them for us.
We will keep you posted on what happens.
