It’s been cold today. I even dug out my winter vest. Adults away for long periods trying to collect food for the chicks. I spent some time looking carefully at the two cameras. I am now sure there are 3 chicks in each nest. Very good news. Swifts only ever have 1 2 or 3 chicks. Never more. I am afraid I didn’t get the 3 chicks in the chimney nest. Often the app closes when I am recording from that nest. Also it’s so hard to pick the right time. Nice clip from the bedroom nest showing clearly the 3 chicks.
