Biology

Diet

This little heron forages either by standing in the water, by sitting on a very low perch over the water to watch and wait for prey to come by, or by stalking its prey. Food items include fish, insects, invertebrates , and amphibians .

Reproduction

The breeding season occurs from late March to late July, with a peak from mid-April to late May. The male and female build a platform-style nest of sticks and twigs in shrubs or small trees close to or over the water. The female lays from 2-7 (usually 2-4) eggs , which both she and the male incubate for 21-25 days. The young are semi-altricial and fledge from the nest 35-35 days after hatching . The adults take care of the young for approximately a month after they fledge. Then the young birds become independent .

Green Herons are solitary nesters and do not nest in rookeries like many other species of herons.

• Breeding Habitat : Wetland-open water
• Clutch Size: 4-5
• Length of Incubation : 21-25 days
• Days to Fledge: 34-35
• Number of Broods: occasionally 2
