A very cold day today. Northeasterly wind ant temperature 10 degrees lower than yesterday. All 4 swifts on camera stayed at home til mid afternoon. I was going to try and move the new camera but as the others had stayed in I decided to delay moving the camera not wanting to disturb the possible new pair so early in their residence. Same weather forecast for tomorrow as well so will probably wait a few days. It’s not going to be easy so putting it off for a couple of days is easy. No clips tonight as they would be exactly the same as yesterday.
