It’s been hot and sunny and swifts screaming round the house most of the day. The chicks are doing great. Parents very attentive and bringing plenty of food. When the “bangers” the non breeding swifts scream flying up to the used nest there is always a parent looking out and screaming back. This is normal swift behaviour.
Managed with the right light to get a clip of the chicks in the chimney nest in colour without IR.
Not much room in the chimney nest to stretch wings
More room in the bedroom nest!
