Common Swift CCTV

Edit:An hour later , it's eventually stopped raining and within minutes both adults are sitting at the entrance and eventually leave , could they sense this rain would ease and decided to wait rather than travel further to feed ?

Apus apus

Just an update re the Common swifts nesting in the loft of my house on the North-east coast of the UK, one of the chicks has disappeared which is sad as they  both seemed fit and healthy . Its raining outside and has been virtually for the past couple of days  , here a nest site sheltered from the elements comes into its own ,no nest to build so it's straight down to breeding , the nest site is well sheltered  and safe from predators although it can get very warm in the loft during the usually warm summer. Swifts usually feed in ahead of a weather front  sometimes going hundreds of miles to find food , a Swift in off the sea the other day could have come from the continent . Today both adults are with the chick and have been all morning , perhaps hoping for it to clear up so they can feed themselves and the single youngster.
