Our blue tits have been busy! Over the last week our suspicions were aroused by the sudden absence of activity after lots of nest building. She must have started laying a few days ago and the eggs been hidden under nesting material, as today at least three, possibly four eggs were revealed. Blue tits typically lay a clutch of 8 - 10 eggs, approximately one a day, before settling down to incubate. So from the comfort of our Visitor Centre we can watch Chichester's peregrines on 4 eggs, Loch Garten's osprey on 3 eggs and our very soon our own blue tits on eggs... but how many?
