Another sunny swift day. Again all 4 swifts out all day returning between 6 and 7 pm. Still no obvious eggs and no brooding behaviour. From the Bristol swift blog it is possible that there have not been enough insects for them to be able to produce eggs yet. It seems that across the country egg laying has been delayed. There were 4 screaming round the house early this morning. Three short clips. The first two showing the empty nests and one showing the bedroom nest swifts moving around.
