La fauna diurna y nocturna en las Islas y Riberas del Ebro: el bosque que no duerme<\/strong><\/p>\n

Las Islas y Riberas del Ebro son un ecosistema fluvial extraordinariamente diverso en fauna y vegetaci\u00f3n. La actividad de la fauna, tanto de aves como de mam\u00edferos, se extiende a lo largo de todas las horas del d\u00eda y de la noche. Cada especie est\u00e1 adaptada a aprovechar un recurso tr\u00f3fico y a no competir entre ellas. Hay especies que solo tienen actividad nocturna y son muy dif\u00edciles de observar; otras que prolongan su actividad durante el crep\u00fasculo o el alba; y algunas que son plenamente diurnas. La adaptaci\u00f3n de la visi\u00f3n y el vuelo silencioso son propias de aves nocturnas, como la ecolocalizaci\u00f3n lo es en el caso de los murci\u00e9lagos. Los cantos y reclamos, tanto de d\u00eda como de noche, son la forma de detectar su presencia, que a menudo pasa desapercibida.<\/p>\n

Day and Night Wildlife in the Ebro Islands and Riverbanks: the Forest that Never Sleeps<\/strong><\/p>\n

The Ebro Islands and Riverbanks form an extraordinarily diverse fluvial ecosystem in terms of fauna and vegetation. The activity of wildlife, both birds and mammals, extends throughout all hours of the day and night. Each species is adapted to exploit a specific food resource and to avoid competition. Some species are exclusively nocturnal and very difficult to observe; others extend their activity into dusk or dawn; and some are fully diurnal. Adaptations such as enhanced vision and silent flight are typical of nocturnal birds, just as echolocation is characteristic of bats. Songs and calls, both by day and by night, are often the only way to detect their otherwise unnoticed presence.<\/p>\n

\u25cf Great Cormorant (Phalacrocorax carbo<\/em>)<\/strong> \u2013 A wintering bird that dives to catch fish and rests on branches with wings spread to dry its plumage.
\u25cf Western Marsh Harrier (Circus aeruginosus<\/em>)<\/strong> \u2013 A bird of prey typical of wetlands that hunts by flying low over vegetation.
\u25cf Black Kite (Milvus migrans<\/em>)<\/strong> \u2013 A migratory bird of prey that breeds in riverside forests and feeds on carrion as well as prey captured on land or in the river.
\u25cf Common Kingfisher (Alcedo atthis<\/em>)<\/strong> \u2013 Feeds on small fish caught by plunge-diving or perching on branches above the water.
\u25cf Eurasian Coot (Fulica atra<\/em>)<\/strong> \u2013 Dives to feed on submerged vegetation. At night it gathers in floating groups to avoid terrestrial predators.
\u25cf Common Moorhen (Gallinula chloropus<\/em>)<\/strong> \u2013 Feeds in shallow waters and along banks, taking refuge in dense reed beds at night.
\u25cf Purple Heron (Ardea purpurea<\/em>)<\/strong> \u2013 Catches prey by waiting motionless in shallow waters. At dusk it reduces activity and retreats to colonies in marsh vegetation.
\u25cf Barn Owl (Tyto alba)<\/em><\/strong> \u2013 Bird of prey specialized in acoustically detecting rodents in the dark. During the day it rests in cavities or buildings.
\u25cf Little Egret (Egretta garzetta<\/em>)<\/strong> \u2013 Fishes during the day in shallow waters with quick movements. At nightfall it moves to shared tree roosts.
\u25cf Audouin\u2019s Gull (Larus audouinii)<\/em><\/strong> \u2013 An endangered gull adapted to coastal environments that travels up the Ebro River. At night it rests on islands or river beaches.
\u25cf Grey Heron (Ardea cinerea<\/em>)<\/strong> \u2013 A long-legged bird that hunts while standing still by the river. It is also active at dusk or on moonlit nights.
\u25cf Mallard (Anas platyrhynchos<\/em>)<\/strong> \u2013 Active both by day and night, feeding on aquatic invertebrates and vegetation. It also migrates in flocks at night.
\u25cf Black-crowned Night Heron (Nycticorax nycticorax<\/em>)<\/strong> \u2013 Mainly active after sunset, with distinctive red eyes adapted to darkness.
\u25cf Eurasian Scops Owl (Otus scops<\/em>)<\/strong> \u2013 The smallest nocturnal bird of prey, mainly insectivorous. Its camouflaged plumage makes it indistinguishable from tree bark during the day.
\u25cf Little Owl (Athene noctua<\/em>)<\/strong> \u2013 Active at dusk, hunting insects and small mammals. It nests and rests in natural cavities or buildings.
\u25cf Eurasian Eagle-Owl (Bubo bubo<\/em>)<\/strong> \u2013 The largest nocturnal bird of prey in Europe. Hunts birds and mammals in transitional zones between forest and open land.
\u25cf Bats<\/strong> \u2013 The only flying mammals. Key insectivores in pest control and allies of agriculture. They hunt in darkness using echolocation and roost during the day in caves, crevices, tree cavities, or bat boxes. The most common species is the Common Pipistrelle (Pipistrellus pipistrellus)<\/em>, but Daubenton\u2019s bat (Myotis daubentonii<\/em>) and the Lesser Horseshoe Bat (Rhinolophus hipposideros<\/em>) are also present.
\u25cf Eurasian Otter (Lutra lutra<\/em>)<\/strong> \u2013 A semi-aquatic mammal that is difficult to observe. Mainly nocturnal and solitary, it feeds on fish and crayfish.<\/p>\n<\/div><\/div><\/div>

Day and Night Wildlife in the Ebro Islands and Riverbanks: the Forest that Never Sleeps<\/strong><\/p>\n

The Ebro Islands and Riverbanks form an extraordinarily diverse fluvial ecosystem in terms of fauna and vegetation. The activity of wildlife, both birds and mammals, extends throughout all hours of the day and night. Each species is adapted to exploit a specific food resource and to avoid competition. Some species are exclusively nocturnal and very difficult to observe; others extend their activity into dusk or dawn; and some are fully diurnal. Adaptations such as enhanced vision and silent flight are typical of nocturnal birds, just as echolocation is characteristic of bats. Songs and calls, both by day and by night, are often the only way to detect their otherwise unnoticed presence.<\/p>\n

\u25cf Great Cormorant (Phalacrocorax carbo<\/em>)<\/strong> \u2013 A wintering bird that dives to catch fish and rests on branches with wings spread to dry its plumage.
\u25cf Western Marsh Harrier (Circus aeruginosus<\/em>)<\/strong> \u2013 A bird of prey typical of wetlands that hunts by flying low over vegetation.
\u25cf Black Kite (Milvus migrans<\/em>)<\/strong> \u2013 A migratory bird of prey that breeds in riverside forests and feeds on carrion as well as prey captured on land or in the river.
\u25cf Common Kingfisher (Alcedo atthis<\/em>)<\/strong> \u2013 Feeds on small fish caught by plunge-diving or perching on branches above the water.
\u25cf Eurasian Coot (Fulica atra<\/em>)<\/strong> \u2013 Dives to feed on submerged vegetation. At night it gathers in floating groups to avoid terrestrial predators.
\u25cf Common Moorhen (Gallinula chloropus<\/em>)<\/strong> \u2013 Feeds in shallow waters and along banks, taking refuge in dense reed beds at night.
\u25cf Purple Heron (Ardea purpurea<\/em>)<\/strong> \u2013 Catches prey by waiting motionless in shallow waters. At dusk it reduces activity and retreats to colonies in marsh vegetation.
\u25cf Barn Owl (Tyto alba)<\/em><\/strong> \u2013 Bird of prey specialized in acoustically detecting rodents in the dark. During the day it rests in cavities or buildings.
\u25cf Little Egret (Egretta garzetta<\/em>)<\/strong> \u2013 Fishes during the day in shallow waters with quick movements. At nightfall it moves to shared tree roosts.
\u25cf Audouin\u2019s Gull (Larus audouinii)<\/em><\/strong> \u2013 An endangered gull adapted to coastal environments that travels up the Ebro River. At night it rests on islands or river beaches.
\u25cf Grey Heron (Ardea cinerea<\/em>)<\/strong> \u2013 A long-legged bird that hunts while standing still by the river. It is also active at dusk or on moonlit nights.
\u25cf Mallard (Anas platyrhynchos<\/em>)<\/strong> \u2013 Active both by day and night, feeding on aquatic invertebrates and vegetation. It also migrates in flocks at night.
\u25cf Black-crowned Night Heron (Nycticorax nycticorax<\/em>)<\/strong> \u2013 Mainly active after sunset, with distinctive red eyes adapted to darkness.
\u25cf Eurasian Scops Owl (Otus scops<\/em>)<\/strong> \u2013 The smallest nocturnal bird of prey, mainly insectivorous. Its camouflaged plumage makes it indistinguishable from tree bark during the day.
\u25cf Little Owl (Athene noctua<\/em>)<\/strong> \u2013 Active at dusk, hunting insects and small mammals. It nests and rests in natural cavities or buildings.
\u25cf Eurasian Eagle-Owl (Bubo bubo<\/em>)<\/strong> \u2013 The largest nocturnal bird of prey in Europe. Hunts birds and mammals in transitional zones between forest and open land.
\u25cf Bats<\/strong> \u2013 The only flying mammals. Key insectivores in pest control and allies of agriculture. They hunt in darkness using echolocation and roost during the day in caves, crevices, tree cavities, or bat boxes. The most common species is the Common Pipistrelle (Pipistrellus pipistrellus)<\/em>, but Daubenton\u2019s bat (Myotis daubentonii<\/em>) and the Lesser Horseshoe Bat (Rhinolophus hipposideros<\/em>) are also present.
\u25cf Eurasian Otter (Lutra lutra<\/em>)<\/strong> \u2013 A semi-aquatic mammal that is difficult to observe. Mainly nocturnal and solitary, it feeds on fish and crayfish.<\/p>\n<\/div><\/div><\/div>
