Flocks of herons also inhabit the salt-works, but their number is decreasing faster than other groups of birds, primarily because of the uncertainty of the environment. On the return from Africa, tens of thousands of swallows use salt-works as a place of rest. It happens that the Hirundo and Delichon swallow fly on the whole territory. Travnik, Saxicola rubetra, yellow wagtail, motacila flava, Spotted Flycatcher fly in flocks of up to 10,000 birds per day!
