The diversity of existing fauna is a consequence of the varied ecological environments that converge in the Palmeral itself. The cultivated areas are frequented by birds such as blackbirds, verdigris, greenfinches and black starlings. Associated with the irrigation network and Azarbe de las Fuentes, moorhens, amphibians such as the common frog, common and midwife toads and cattle herons, which tend to feed on insects in fields traveled by livestock, are not uncommon. In 2013, 200 specimens of fartet, an endemic fish in serious danger of extinction that feed on mosquito larvae and that seems to have adapted to this small artificial lagoon, were introduced into an irrigation pond in the Palm Grove. The forest influence of the surrounding mountains favors the presence of the “Pito real”, which also usually makes its nests in the same trunks of palm trees, and many other birds such as partridges, warblers, robins, chickadees, redstarts, owlets, scops, owls, shrikes and kestrels. Due to the proximity to the urban area, sparrows, swifts and common planes are abundant.
