The Rustic Frog
House Martin Egg Shell Patterning, (Delichon urbicum) (Explored)
Now, for the 3rd year running, we have another 3 young House Martins developing fast. These are the 3 egg shells found in the garden, 2 on the 29th May with an interesting fine pattern inside, (showing through the light) and the last one found 2 days later on 31st May with no patterning inside?
The shells are incredibly delicate and only the size of a small fingernail. Alas, since this photograph was taken, the birds have not visited again since 2020.
