Please credit: Scottish Wildlife Trust. A female osprey has laid her third egg of the season at a reserve run by the Scottish Wildlife Trust in Perth and Kinross. The bird coded NC0 laid the latest egg at the Loch of the Lowes wildlife reserve near Dunkeld at around 7.40am on Saturday. NC0 was ringed as a chick near Loch Ness in 2016, with her 13-year-old mate LM12 breeding at the Loch of the Lowes for 10 seasons. Osprey eggs are the same size as large hen eggs and NC0’s chicks are expected to hatch in mid to late-May.
