Longueur 85-102 cm, envergure 140-170 cm, poids 960-1 680 g.
Elle habite les grandes zones humides de plaine, s'installant souvent dans les larges roselières épaisses et inaccessibles. Ses terrains de chasse comprennent les prairies humides ou sèches, marais, rizières, lacs et étangs.
La Grande Aigrette se nourrit surtout de poissons et d'insectes aquatiques lorsqu'elle peut pêcher, sinon de micromammifères et d'insectes terrestres. Elle peut s'attaquer également aux lézards, aux mollusques et aux jeunes oiseaux.
L'espèce chasse souvent seule ou en petits groupes éparpillés. Les rassemblements en période internuptiale comprennent parfois quelques dizaines d'individus. Le couple se forme au retour de printemps. Elle niche isolément ou en colonie. Après une période de vols d'observation autour de la colonie, les mâles commencent à défendre vigoureusement les sites de nid potentiels. Chacun construit de petites plates-formes qui servent de sites de parade. Les plumes scapulaires érectiles sont en évidence durant les parades.
Le nid est une pile de roseaux ou de branchettes garnie de matériaux plus fins, pouvant dépasser 1 m de diamètre. Il est construit dans une roselière inondée, dans un arbre ou un arbuste au-dessus de l'eau. Les nids arboricoles peuvent se toucher mais sont nettement espacés dans les roselières. La ponte unique de 3-5 œufs (extrêmes : 2-6) est déposée à partir d'avril. L'incubation dure 25-26 jours et les jeunes sont volants vers l'âge de 42 jours.

The map presents a summary at the 10 x 10 km grid of the observation data for the species transmitted to the SINP. These data have been subjected to validation filters.
The map presents a reference distribution layer of the species at the scale of departments and marine sectors. The presence and absence data were established by expertise within a network of partners. This reference distribution is used in the validation process of the SINP data at the INPN level.
Corresponds to a report on the basis of at least one observation proved within a period of 10 years (20 years for little-known invertebrates) preceding the year and no presumption of extinction since obtaining the last data nor doubt on reproductive and implemented nature of this population. For migratory species, the presence indicated concerns areas of reproduction.
This status is based on one or more of the following criteria:
This point covers the absence, more difficult by nature to demonstrate than presence. This status is based on one or more of the following criteria:
This status must be assigned to a department in which the presence of the species is casual.
Particular case of absence due to a proven extinction less than a half century ago (older disappearances are treated as "no probable or definite").
In the state of knowledge, we can not comment on the presence or absence in the current department. This is the default status when not comprised in one of the previous categories or whenever there is doubt.
The map shows the global distribution of the species based on GBIF data (Global Biodiversity Information Facility).
