More eggs!

When I looked this morning, I think I could see 4 eggs in the oak tree nestbox. Just as well I looked early on, as later the blue tit came in and covered up the eggs. Reading up on various blogs and forums, I discovered that the eggs can be laid over a period of a week or so and incubation does not start in earnest until all the clutch is laid. This ensures that all the eggs hatch at the same time, rather than staggered a week. There has been very little activity in any of the boxes today, but the bluetit returned and settled on the eggs once it was dark. This shot shows the eggs covered over with some of Bryn’s fur from the nesting feeder!
