The swifts are feeling the heat today! Both pairs appear to be incubating eggs, with Box 6 starting incubation on 12th with hatching due around 1st July. Still not sure what’s going on with Box 1 - the parents still appear to be incubating but we cannot see the eggs for feathers! Here they are, suffering from the heat, (hence the open bills to try to cool off) and having just done a changeover on the nest.
