Large groups of gulls use the wetlands, above all when the sea is rough. The black-headed gull, the Mediterranean gull, the lesser black-backed gull, the slender-billed gull can often be seen during the winter. The most common birds of prey of the wetlands of south-eastern Sicily are the western marsh harrier and the osprey and in the winter numerous booted eagles, spotted eagles and short-toed eagles are also present.
With the Spring migrations which last from late February to the end of May, you can see white spoonbills, the curious glossy ibis, and many other small and medium-sized wading birds like the black-winged stilt, the common and the little curlew, the avocet, the black-tailed godwit and the ruff, and in late spring, little stints and sanderlings on their way to the Arctic regions for nesting. The trees in the countryside around the marshes fill with small birds which have also arrived from the African continent: spotted flycatchers, European pied flycatchers, collared flycatchers, Western yellow wagtails, Eastern subalpine warblers, as well as European turtle doves, Eurasian golden orioles, Eurasian hoopoes, European bee-eaters and common cuckoos, while the air above the wetlands is filled with swallows, swifts, and common house martins.
