Great Egret (Ardea alba)
By Lisa Graham
The Great Egret is one of the most iconic and visually striking birds you might encounter in wetlands, marshes, and coastal areas. With its snow-white plumage, long neck, and elegant stature, this bird is hard to miss and utterly mesmerizing. If you’re looking to catch a glimpse of these majestic creatures, you’ll want to venture to areas with abundant shallow water and fish – not something you’ll find in a typical backyard.
Reaching heights of 40 inches and boasting wingspans that can extend over five feet, the Great Egret is a symbol of grace and beauty. As they stand in the shallows, their striking yellow beaks and black legs contrast sharply against their pure white feathers. When in breeding plumage, males sport elegant, long ornamental plumes that cascade down their backs – that’s pretty hard to resist!
Great Egrets are renowned for their hunting prowess. They exhibit a mix of patience and precision as they wade through the water, waiting motionless for their prey to approach. Their diet primarily consists of fish, frogs, and small crustaceans. With a quick thrust of their long beak, they have perfected the art of spearing fish, making them effective hunters. Unlike their more frantic relatives, these egrets exude a calm, deliberate demeanor.
During the breeding season, which typically occurs in the spring and early summer, male Great Egrets perform elaborate courtship displays to attract females. They will stretch their necks high, engage in sham fights, and showcase their beautiful plumes. Once they’ve formed a pair bond, they will collaboratively build large nests made from twigs and branches, often found in the dense vegetation of wetlands or trees near water.
In the colony, both parents play active roles in raising their young. Clutches typically consist of three to five eggs, which incubate for about 25 to 30 days. Once hatched, the nestlings are fed and cared for until they fledge, which can take several weeks. Sibling rivalry can be fierce, as the parents may face pressure to provide enough food for all their young, leading to a struggle for survival among the nestlings. The Great Egret saw significant population declines in the late 19th and early 20th centuries due to the feather trade. Demand for their beautiful plumes for fashion led to conservation efforts, and these magnificent birds have since made a remarkable comeback, thanks in part to the establishment of wildlife protection laws.
Great Egrets are common in the Austin area. You can find them along the Colorado River, in Lady Bird Lake, and in McKinney Falls State Park. Look for them anywhere there are ponds, marshes, rivers and lakes.
