A fourth young marsh harrier appeared this morning! As the usual clutch size is 4-5 eggs, this isn't surprising, but females can lay as many as 8 eggs, so how many more are there?

The timing of their appearance is interesting - 21st, 23rd, 28th, 30th. This five-day interval between the second and third fledglings suggests that the third chick died, and we are seeing numbers 1, 2, 4, 5.
