Just thought I would post pics of my lovely house martin egg shells. These are from the higher nest, which is occupied by a pair who returned on time, on April 18th. There are two other nests occupied by very busy housemartins under the lower eaves. They caused me great anxiety as they did not return until May 10th.
I don't know how many eggs in total as I rarely find the eggs from this nest as it is so high, they usually just get blown away or land on the small roof beneath. Luckily, these landed on the path.

Thanks Robbo. I must admit I have never seen sparrows attempting to go anywhere near that nest......doesn't mean they haven't of course. Pics of the lower nests below, not very good as dark & raining here. Please excuse state of house, it needs painting after new windows installed :-D
Sorry to hear your HM are still threatened.
