Genus: Bubulcus
Bonaparte, 1855
Species: B. ibis

The Cattle Egret (Bubulcus ibis) is a cosmopolitan species of heron (family Ardeidae) found in the tropics, subtropics and warm temperate zones. It is the only member of the monotypic genus Bubulcus, although some authorities regard its two subspecies as full species, the Western Cattle Egret and the Eastern Cattle Egret. Despite the similarities in plumage to the egrets of the genus Egretta, it is more closely related to the herons of Ardea. Originally native to parts of Asia, Africa and Europe, it has undergone a rapid expansion in its distribution and successfully colonised much of the rest of the world.

It is a stocky white bird adorned with buff plumes in the breeding season which nests in colonies, usually near bodies of water and often with other wading birds. The nest is a platform of sticks in trees or shrubs. Unlike most other herons, it feeds in relatively dry grassy habitats, often accompanying cattle or other large mammals, since it catches insect and small vertebrate prey disturbed by these animals. Some populations of the Cattle Egret are migratory and others show post-breeding dispersal.

The adult Cattle Egret has few predators, but birds or mammals may raid its nests, and chicks may be lost to starvation, calcium deficiency or disturbance from other large birds. This species removes ticks and flies from cattle, but it can be a safety hazard at airfields, and has been implicated in the spread of tick-borne animal diseases.

AIRONE GUARDABUOI

Nome scientifico: Bubulcus Ibis
Ordine: Ciconiiformes
Famiglia: Ardeidae

Airone di piccole dimensioni (48-53 cm) dal piumaggio bianco candido e dal becco giallo, apertura alare di circa 100 cm. E' il meno "acquatico" degli aironi. Si alimenta di solito nelle vicinanze delle mandrie di bovini al pascolo, i quali, pascolando, fanno muovere dal terreno prede, come cavallette, coleotteri e lucertole, di cui si nutre. La dieta include inoltre molti invertebrati che sono pericolosi parassiti dei bovini, come zecche e mosche emofaghe, per cui è possibile vederli appollaiati sopra i bovini al pascolo. In realtà i ruminanti non traggono benefici solo dalla liberazione dei parassiti, ma, questi uccelli, sono pronti a dare l'allarme in caso di pericolo (da qui il nome di airone guardabuoi). Ora i guardabuoi hanno imparato che possono avere gli stessi risultati seguendo nei campi le macchine agricole che smuovono gli insetti dal terreno. Quando caccia nell'acqua si nutre di rane e pesci. E' diffuso in tutto il mondo, in Italia vive nelle zone costiere della Sardegna e, con minor diffusione, nelle zone risicole della pianura Padana. Nidifica sugli alberi in dense colonie, spesso in compagnia di altre specie di aironi (garzaie). I nidi spesso sono così vicini da toccarsi gli uni con gli altri (a volte fino a 100 nidi sullo stesso albero).

Ciao Luciano,
On daily events, chat are ..:)
A lovely capture of this egrets. Good composition with sharp details.

Ciao Luciano,
non si tratta certamente di Garzette, ma credo siano dei Guardabuoi, che eventualmente potrebbero essere confusi con Airone bianco maggiore, che è però decisamente più grande sia della Garzetta che del Guardabuoi. In fotografia le dimensioni sono difficili da giudicare se non ci sono confronti diretti, ma in questo caso le sagome mi sembrano quelle tipiche del Guardabuoi, anche se ovviamente, dato il periodo, non hanno alcun segno di livrea riproduttiva. Bella cattura, dalle mie parti ne posso osservare molti in questa stagione.
Grazie e complimenti
Buona serata
Ciao Maurizio

Bonjour Luciano,

Les arbres cadrent bien les oiseaux. La prise de vue permet de voir les détails et les couleurs des Hérons garde-boeufs. la lumière de l,après-midi rehausse les couleurs de l'image. Bonne journée.

Pierre

Interesante toma de este grupo de Bubulcus. Por aquí los tenemos
con relativa abundancia.
Saludos Luciano:
