It is a karstic marsh in western Bulgaria near the town of Slivnitsa.
It is close to Dragoman marsh.
Not so impressive, but it has its beauty.
My friend, with whom we took these pictures, has caught fish in it. There is pike in it.
In Aldomirovtsi marsh nest or reside many birds.
Unfortunately they were frightened and it was extremely difficult to take pictures.
Because of the warm weather the insects were calm and I was able to shoot several butterflies and beetles.
In the autumn or the next spring I will visit it again to try again to photograph the birds in the reserve.
